    Incorrect

    • A 27-year-old woman comes in for her regular prenatal check-up at 30 weeks gestation. She reports feeling well and has had an uncomplicated pregnancy thus far. Her vital signs are as follows:
      Respiratory rate: 18 breaths/min
      Heart rate: 70 beats/min
      Blood pressure: 130/88 mmHg
      Temperature: 37.2ºC
      Oxygen saturation: 97% on room air
      Urinalysis results show:
      Protein: +
      Glucose: -
      Nitrites: -

      What is the most appropriate course of action for this patient?

      Your Answer: Prophylactic aspirin

      Correct Answer: Routine management

      Explanation:

      If a pregnant woman has new-onset BP ≥ 140/90 mmHg after 20 weeks AND ≥ 1 of proteinuria, organ dysfunction, she is diagnosed with pre-eclampsia. However, if a patient presents to a routine antenatal appointment at 28 weeks gestation and her blood pressure does not meet the threshold of ≥ 140/90 mmHg, she should continue with routine management even if her urine is positive for protein. Therefore, commencing nifedipine and fluid restriction is incorrect as they are only used in the management of severe pre-eclampsia. Similarly, commencing prophylactic aspirin, prophylactic aspirin and labetalol, or prophylactic aspirin and nifedipine is incorrect as they are only used if the patient is diagnosed with pre-eclampsia.

      Pre-eclampsia is a condition that occurs during pregnancy and is characterized by high blood pressure, proteinuria, and edema. It can lead to complications such as eclampsia, neurological issues, fetal growth problems, liver involvement, and cardiac failure. Severe pre-eclampsia is marked by hypertension, proteinuria, headache, visual disturbances, and other symptoms. Risk factors for pre-eclampsia include hypertension in a previous pregnancy, chronic kidney disease, autoimmune disease, diabetes, chronic hypertension, first pregnancy, and age over 40. Aspirin may be recommended for women with high or moderate risk factors. Treatment involves emergency assessment, admission for observation, and medication such as labetalol, nifedipine, or hydralazine. Delivery of the baby is the most important step in management, with timing depending on the individual case.

    Correct

    • A 29-year-old woman who is 39-weeks pregnant presents to the labour suite with sporadic contractions. She had noticed a mucous plug in her underwear earlier in the day. Upon examination, she appears to be breathing heavily and experiencing some discomfort. The cardiotocography is normal and progressing smoothly. During a vaginal examination, her cervix is estimated to be dilated at 2 cm. What phase of labour is she currently in?

      Your Answer: Latent 1st stage

      Explanation:

      The correct stage of labour for a woman with a cervix that is just beginning to ripen and dilate is the latent phase of the 1st stage. This stage is characterized by a cervix dilation of 0-3 cm. The active phase of the 1st stage, which is characterized by a cervix dilation of 3-10 cm and more regular contractions, is not applicable in this scenario. The active 2nd stage is also not a descriptive stage of labour, as it only refers to the general stage that ends with the expulsion of the foetus.

      Labour is divided into three stages, with the first stage beginning from the onset of true labour until the cervix is fully dilated. This stage is further divided into two phases: the latent phase and the active phase. The latent phase involves dilation of the cervix from 0-3 cm and typically lasts around 6 hours. The active phase involves dilation from 3-10 cm and progresses at a rate of approximately 1 cm per hour. In primigravidas, this stage can last between 10-16 hours.

      During this stage, the baby’s presentation is important to note. Approximately 90% of babies present in the vertex position, with the head entering the pelvis in an occipito-lateral position. The head typically delivers in an occipito-anterior position.

    Correct

    • A 35-year-old primip is being evaluated on day six postpartum for unilateral breast discomfort. The discomfort began two days ago, and despite continuing to breastfeed, it has not improved. She feels generally fatigued, but she is currently eating and drinking well.
      During the examination, you observe an erythematosus, firm, and swollen area in a wedge-shaped distribution on the right breast. There is a small crack in the nipple. The examination is painful.
      Her vital signs are stable, and her temperature is 37.5 °C.
      What is the most appropriate initial management, given the above information?

      Your Answer: Advise her to continue breastfeeding and start empirical antibiotics

      Explanation:

      Management of Lactational Mastitis: Advice for Patients

      Lactational mastitis is a common condition that affects breastfeeding women. It is important to manage this condition promptly to prevent complications such as breast abscesses. Here are some management options for lactational mastitis:

      1. Advise her to continue breastfeeding and start empirical antibiotics: If the patient presents with lactational mastitis and has a nipple fissure, it is suggestive of an infective cause. In this case, the patient should be reassured, asked to continue breastfeeding, offered adequate analgesia, and started on empirical antibiotics.

      2. Reassure the patient, ask her to continue expressing milk and review if there is no improvement in two days: If there is no evidence of infection, reassurance and advice to continue breastfeeding, as well as simple analgesia, are a good first management option. However, if symptoms do not improve in 24 hours, then there is an indication for starting empirical antibiotics.

      3. Admit the patient to hospital for intravenous antibiotics and drainage: Admission is advisable for intravenous antibiotics and drainage if oral antibiotics fail to improve symptoms, the patient develops sepsis, or there is evidence of the development of a breast abscess.

      4. Advise her to continue breastfeeding and send a breast milk culture and treat if positive: A breast milk culture should be sent before starting antibiotics, but in this case, given the patient fulfils the criteria for starting empirical treatment, you should not delay antibiotic therapy until the breast milk culture is back.

      5. Reassure the patient, advise her to continue breastfeeding and offer simple analgesia: Reassurance, advice to continue breastfeeding, and simple analgesia are offered to women who first present with lactational mastitis. If symptoms do not improve after three days, there is an indication to offer empirical antibiotics.

      In conclusion, lactational mastitis should be managed promptly to prevent complications. Patients should be advised to continue breastfeeding, offered adequate analgesia, and started on empirical antibiotics if necessary. If symptoms do not improve, further management options should be considered.

    Incorrect

    • A 30-year-old woman with a previous macrosomic baby and a history of gestational diabetes presents in her second pregnancy. She is at eight weeks’ gestation and attends the midwife booking visit.
      What is the most suitable test to diagnose gestational diabetes in this patient?

      Your Answer: A 2-hour oral glucose tolerance test (OGTT) at 24–28 weeks

      Correct Answer: A 2-hour OGTT as soon as possible following the booking visit

      Explanation:

      Gestational diabetes is a condition where pregnant women experience high blood sugar levels. It is diagnosed through a 2-hour oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy. Women with risk factors such as a BMI over 30, a previous macrosomic baby, a family history of diabetes, or from an area with high diabetes prevalence should be offered the test. Random serum glucose, fasting serum glucose, HbA1c, and urinalysis are not recommended for diagnosis. Gestational diabetes can have negative effects on both the mother and fetus, including fetal macrosomia, stillbirth, neonatal hypoglycemia, and an increased risk of type II diabetes and obesity in the baby’s later life. Women with pre-existing diabetes should have their HbA1c monitored monthly and at booking to assess pregnancy risk, but HbA1c is not used to diagnose gestational diabetes. Early detection and management of gestational diabetes is crucial to prevent complications.

      Regrettably, the mother experienced a perineal tear during delivery. The tear involves the superficial and deep transverse perineal muscles, but the anal sphincter remains intact.

      What is the recommended course of action for management?

      Your Answer: Suturing on the ward

      Explanation:

      A second-degree perineal tear can be repaired on the ward by a midwife or clinician with sufficient experience. This type of tear involves the perineal muscle but not the anal sphincter, and is commonly seen in first-time mothers. Repairing the tear on the ward is a safe option that does not pose any long-term risks. For first-degree tears, a conservative approach is usually taken as they only involve superficial damage. Packing and healing by secondary intention is not appropriate for perineal tears, as it is a treatment for abscesses. Referring the patient to a urogynaecology clinic is also not necessary, as perineal tears require immediate repair. Repair in theatre is reserved for third and fourth-degree tears, which involve the anal sphincter complex and rectal mucosa.

      Perineal tears are a common occurrence during childbirth, and the Royal College of Obstetricians and Gynaecologists (RCOG) has developed guidelines to classify them based on their severity. First-degree tears are superficial and do not require any repair, while second-degree tears involve the perineal muscle and require suturing by a midwife or clinician. Third-degree tears involve the anal sphincter complex and require repair in theatre by a trained clinician, with subcategories based on the extent of the tear. Fourth-degree tears involve the anal sphincter complex and rectal mucosa and also require repair in theatre by a trained clinician.

      There are several risk factors for perineal tears, including being a first-time mother, having a large baby, experiencing a precipitant labour, and having a shoulder dystocia or forceps delivery. It is important for healthcare providers to be aware of these risk factors and to provide appropriate care and management during childbirth to minimize the risk of perineal tears. By following the RCOG guidelines and providing timely and effective treatment, healthcare providers can help ensure the best possible outcomes for both mother and baby.

    Correct

    • A 35-year-old woman comes to the obstetric clinic during her 28th week of pregnancy. She has been diagnosed with gestational diabetes and has been taking metformin for the past two weeks. However, her blood glucose levels are still elevated despite following a strict diet and taking the maximum dose of metformin. What is the next best course of action to manage her blood glucose levels?

      Your Answer: Add on insulin therapy

      Explanation:

      When a woman has gestational diabetes, it is important to control her blood glucose levels to prevent complications such as premature birth, stillbirth, and macrosomia. If diet and exercise changes along with metformin do not meet blood glucose targets, insulin therapy should be added, according to NICE guidelines. Sulfonylureas are not recommended for gestational diabetes as they are less effective than the metformin and insulin combination and have been shown to be teratogenic in animals. Metformin should not be stopped as it increases insulin sensitivity, which is lacking during pregnancy. SGLT-2 antagonists are also not recommended due to their teratogenic effects in animals. Continuing metformin alone for two weeks despite high blood glucose levels increases the risk of complications, so insulin therapy should be added at this stage.

      Gestational diabetes is a common medical disorder affecting around 4% of pregnancies. Risk factors include a high BMI, previous gestational diabetes, and family history of diabetes. Screening is done through an oral glucose tolerance test, and diagnostic thresholds have recently been updated. Management includes self-monitoring of blood glucose, diet and exercise advice, and medication if necessary. For pre-existing diabetes, weight loss and insulin are recommended, and tight glycemic control is important. Targets for self-monitoring include fasting glucose of 5.3 mmol/l and 1-2 hour post-meal glucose levels.

    Correct

    • A 35-year-old woman has been diagnosed with gestational diabetes during her second pregnancy. Despite progressing well, she has been experiencing persistent nausea and vomiting throughout her pregnancy. In her previous pregnancy, she tried taking metformin but it worsened her symptoms and caused frequent loose stools. As a result, she refuses to take metformin again. She has made changes to her diet and lifestyle for the past two weeks, but her blood results show little improvement. Her fasting plasma glucose levels are 6.8 mmol/L, which is still above the normal range of <5.3mmol/L. What should be the next step in managing her gestational diabetes?

      Your Answer: Commence insulin

      Explanation:

      If blood glucose targets are not achieved through diet and metformin in gestational diabetes, insulin should be introduced as the next step. This is in accordance with current NICE guidelines, which recommend that pregnant women with any form of diabetes aim for plasma glucose levels below specific target values. Commencing anti-emetic medications or metformin would not be the most appropriate options in this scenario, as the former would not address the underlying issue of gestational diabetes and the latter is not acceptable to the patient. Additionally, offering a 2 week trial of diet and exercise changes would not be appropriate at this stage, as medication is now required. However, this may be an option for patients with a fasting plasma glucose of between 6.0 and 6.9 mmol/L without complications, who can be offered a trial of diet and exercise for 2 weeks before medication is considered if blood glucose targets are not met.

    Incorrect

    • A 28-year-old woman attends the antenatal clinic at 41 weeks of gestation, worried that she has not yet gone into labour. She reports normal foetal movements and has not been recently ill. She has no significant medical history and this is her first pregnancy. On examination, her abdomen is soft and a palpable uterus is consistent with a term pregnancy. Her Bishop's score is calculated as 5. What is the first step in managing this patient?

      Your Answer: Vaginal prostaglandins

      Correct Answer: Membrane sweep

      Explanation:

      Before inducing a pregnancy, it is important to calculate the Bishop’s score to determine if spontaneous labor is likely or if induction may be needed. For this patient who is past her due date, a score below 8 suggests that induction may be necessary. The most initial step in this case is a membrane sweep, which can be performed in the antenatal clinic by a midwife or obstetrician. This method involves separating the chorionic membrane from the decidua to trigger natural labor and is considered an adjunct to labor rather than an actual method of induction.

      While an artificial rupture of membranes (amniotomy) is another method of induction, it carries certain risks such as increased risk of cord prolapse and infection, making it a less favorable option. If a membrane sweep alone is not enough to induce labor, vaginal prostaglandins are recommended according to NICE guidelines. Oxytocin can also be used to stimulate uterine contraction, but it is not recommended as the initial step in induction due to the risks of uterine contraction against an unprimed cervix.

      It is important to note that this patient’s Bishop’s score is 5 and she is already at 41-weeks gestation, which increases the risk of complications such as macrosomia and stillbirth. Therefore, it is inappropriate to discharge her without discussing methods of inducing labor.

      Induction of labour is a process where labour is artificially started and is required in about 20% of pregnancies. It is indicated in cases of prolonged pregnancy, prelabour premature rupture of the membranes, maternal medical problems, diabetic mother over 38 weeks, pre-eclampsia, obstetric cholestasis, and intrauterine fetal death. The Bishop score is used to assess whether induction of labour is necessary and includes cervical position, consistency, effacement, dilation, and fetal station. A score of less than 5 indicates that labour is unlikely to start without induction, while a score of 8 or more indicates a high chance of spontaneous labour or response to interventions made to induce labour.

      Possible methods of induction include membrane sweep, vaginal prostaglandin E2, oral prostaglandin E1, maternal oxytocin infusion, amniotomy, and cervical ripening balloon. The NICE guidelines recommend vaginal prostaglandins or oral misoprostol if the Bishop score is less than or equal to 6, while amniotomy and an intravenous oxytocin infusion are recommended if the score is greater than 6.

      The main complication of induction of labour is uterine hyperstimulation, which refers to prolonged and frequent uterine contractions that can interrupt blood flow to the intervillous space and result in fetal hypoxemia and acidemia. Uterine rupture is a rare but serious complication. Management includes removing vaginal prostaglandins and stopping the oxytocin infusion if one has been started, and considering tocolysis.

    Correct

    • A 32-year-old woman who is P1 G2 is 30 minutes post-partum of an uncomplicated delivery. Suddenly, she starts gasping for breath and appears cyanosed with a blood pressure of 83/65 mmHg, heart rate of 120 bpm, and a respiratory rate of 33/min. She becomes unresponsive. What is the probable diagnosis?

      Your Answer: Amniotic fluid embolism

      Explanation:

      The symptoms and time frame mentioned in the question strongly suggest an amniotic fluid embolism, which typically occurs during or within 30 minutes of labor and is characterized by respiratory distress, hypoxia, and hypotension. On the other hand, intracranial hemorrhage is usually preceded by a severe headache, while convulsions are indicative of eclampsia and drug toxicity. The symptoms experienced by the patient during normal labor would not be expected in cases of drug toxicity. Additionally, hypoxia is not a typical symptom of drug toxicity.

      Amniotic fluid embolism is a rare but serious complication of pregnancy that can result in a high mortality rate. It occurs when fetal cells or amniotic fluid enter the mother’s bloodstream, triggering a reaction that leads to various signs and symptoms. While several risk factors have been associated with this condition, such as maternal age and induction of labor, the exact cause remains unclear. It is believed that exposure of maternal circulation to fetal cells or amniotic fluid is necessary for the development of an amniotic fluid embolism, but the underlying pathology is not well understood.

      The majority of cases of amniotic fluid embolism occur during labor, but they can also occur during a cesarean section or in the immediate postpartum period. Symptoms of this condition include chills, shivering, sweating, anxiety, and coughing, while signs may include cyanosis, hypotension, bronchospasms, tachycardia, arrhythmia, and myocardial infarction. Diagnosis is primarily clinical and based on exclusion, as there are no definitive diagnostic tests available.

      Management of amniotic fluid embolism requires a multidisciplinary team and critical care unit. Treatment is mainly supportive, focusing on addressing the patient’s symptoms and stabilizing their condition. Given the high mortality rate associated with this condition, prompt recognition and management are crucial for improving outcomes.

    • A 26-year-old woman with type 1 diabetes mellitus visits her General Practitioner (GP) with her partner to seek advice on nutritional supplementation as they plan to start trying for a baby. She is not using any contraception and her diabetes is well managed, with her latest HbA1c level at 32 mmol/mol (recommended by the Royal College of Obstetricians and Gynaecologists < 48 mmol/mol). What is the most suitable recommendation for folic acid supplementation?

      Your Answer: Commence folic acid 5 mg daily now and continue throughout pregnancy

      Correct Answer: Commence folic acid 5 mg daily now and continue until week 12 of gestation

      Explanation:

      Folic Acid Supplementation in Pregnancy

      Explanation: Folic acid supplementation is recommended for all women who are trying to conceive and during pregnancy to reduce the risk of neural tube defects and other congenital abnormalities. The recommended dose is 400 micrograms daily from the preconception period until the 12th week of gestation. However, women with certain high-risk factors, such as diabetes, a family history of neural tube defects, or obesity, are advised to take a higher dose of 5 mg daily from the preconception period until the 12th week of gestation. It is important to continue folic acid supplementation until the end of the first trimester to ensure proper formation of the brain and other major organs in the body. Side-effects of folic acid treatment may include abdominal distension, reduced appetite, nausea, and exacerbation of pernicious anaemia.

    Incorrect

    • A 35-year-old pregnant woman attends the Obstetric clinic for a routine early pregnancy scan. She has been struggling so far during the pregnancy, suffering from extreme, persistent nausea and vomiting. On the ultrasound scan, the image observed resembles ‘a snow storm’. The physician is concerned that this may be a complete molar pregnancy.
      What percentage of complete molar pregnancies go on to become invasive?

      Your Answer: 66%

      Correct Answer: 15%

      Explanation:

      Hydatidiform Moles and Choriocarcinoma

      Hydatidiform moles are tumours of trophoblastic villi that can be classified into two subtypes: partial and complete. Both subtypes have the potential to become invasive and develop into choriocarcinoma, a malignant trophoblastic tumour. Macroscopically, a complete molar pregnancy resembles a bunch of grapes and appears like a snowstorm on ultrasound scans. Approximately 15% of complete moles become invasive, and the incidence of subsequent choriocarcinoma is around 3%. It is crucial to remove the molar pregnancy from the patient due to the risk of invasion and carcinoma. Post-evacuation, it is essential to monitor serum human chorionic gonadotropin (HCG) levels to follow up on the patient’s condition.

    Correct

    • A 32-year-old pregnant woman comes for a routine check at 28 weeks gestation. During the examination, her symphysis-fundal height measures 23 cm. What is the most crucial investigation to confirm these findings?

      Your Answer: Ultrasound

      Explanation:

      The symphysis-fundal height measurement in centimetres should correspond to the foetal gestational age in weeks with an accuracy of 1 or 2 cm from 20 weeks gestation. Hence, it can be deduced that the woman is possibly experiencing fetal growth restriction. Therefore, it is crucial to conduct an ultrasound to verify if the foetus is indeed small for gestational age.

      The symphysis-fundal height (SFH) is a measurement taken from the pubic bone to the top of the uterus in centimetres. It is used to determine the gestational age of a fetus and should match within 2 cm after 20 weeks. For example, if a woman is 24 weeks pregnant, a normal SFH would be between 22 and 26 cm. Proper measurement of SFH is important for monitoring fetal growth and development during pregnancy.

      Blood negative
      Protein negative
      Glucose trace
      Nitrites negative
      Leukocytes negative
      What would be the most suitable course of action next?

      Your Answer: Request an oral glucose tolerance test

      Correct Answer: Reassure and safety-net

      Explanation:

      During pregnancy, hormonal changes can lead to increased blood flow to the kidneys and an increase in the glomerular filtration rate (GFR), allowing for more efficient filtering of the blood. The patient’s symphysis-fundal height is within the expected range, indicating that the baby is not macrosomic. The patient does not exhibit symptoms of gestational diabetes, such as polyuria, polydipsia, or nocturia, and does not have any risk factors for the condition. Therefore, arranging for a fasting glucose test is not the best option for diagnosing or excluding gestational diabetes. Instead, an OGTT should be considered the gold standard. Prescribing labetalol is not necessary as the patient does not exhibit any concerning signs of pre-eclampsia. Similarly, prescribing metformin is not indicated as the patient has not been diagnosed with gestational diabetes and does not require medication for diabetes at this time.

      Physiological Changes During Pregnancy

      The human body undergoes significant physiological changes during pregnancy. The cardiovascular system experiences an increase in stroke volume by 30%, heart rate by 15%, and cardiac output by 40%. However, systolic blood pressure remains unchanged, while diastolic blood pressure decreases in the first and second trimesters, returning to non-pregnant levels by term. The enlarged uterus may interfere with venous return, leading to ankle edema, supine hypotension, and varicose veins.

      The respiratory system sees an increase in pulmonary ventilation by 40%, with tidal volume increasing from 500 to 700 ml due to the effect of progesterone on the respiratory center. Oxygen requirements increase by only 20%, leading to over-breathing and a fall in pCO2, which can cause a sense of dyspnea accentuated by the elevation of the diaphragm. The basal metabolic rate increases by 15%, possibly due to increased thyroxine and adrenocortical hormones, making warm conditions uncomfortable for women.

      The maternal blood volume increases by 30%, mostly in the second half of pregnancy. Red blood cells increase by 20%, but plasma increases by 50%, leading to a decrease in hemoglobin. There is a low-grade increase in coagulant activity, with a rise in fibrinogen and Factors VII, VIII, X. Fibrinolytic activity decreases, returning to normal after delivery, possibly due to placental suppression. This prepares the mother for placental delivery but increases the risk of thromboembolism. Platelet count falls, while white blood cell count and erythrocyte sedimentation rate rise.

      The urinary system experiences an increase in blood flow by 30%, with glomerular filtration rate increasing by 30-60%. Salt and water reabsorption increase due to elevated sex steroid levels, leading to increased urinary protein losses. Trace glycosuria is common due to the increased GFR and reduction in tubular reabsorption of filtered glucose.

      Calcium requirements increase during pregnancy, especially during the third trimester and lactation. Calcium is transported actively across the placenta, while serum levels of calcium and phosphate fall with a fall in protein. Ionized levels of calcium remain stable, and gut absorption of calcium increases substantially due to increased 1,25 dihydroxy vitamin D.

      The liver experiences an increase in alkaline phosphatase by 50%,

    Correct

    • A 36-year-old pregnant woman has a vaginal swab taken at 34 weeks gestation despite being asymptomatic. She informs you that during her previous pregnancy a bacteria which can cause sepsis in babies was detected on one of her swabs, which is why she needs to be tested again.

      The microbiology report reads as follows:
      Sample: Positive (awaiting sensitivities)
      Gram stain: Positive
      Morphology: Cocci in chains
      Growth requirements: Facultative anaerobe

      What is the most likely organism present based on this report?

      Your Answer: Streptococcus agalactiae

      Explanation:

      Mothers who have previously tested positive for Group B Streptococcus during pregnancy should be given intravenous antibiotics as a preventative measure during labor or offered testing in late pregnancy and given antibiotics if the test is positive. Group B Streptococcus is a bacterium that can cause severe infections in newborns, including pneumonia and meningitis. It is a Gram-positive coccus that forms chains and is a facultative anaerobe. In contrast, Neisseria gonorrhoeae is a Gram-negative, diplococcus that requires oxygen to grow and is associated with conjunctivitis in newborns. Clostridium difficile is a Gram-positive, anaerobic bacillus that causes diarrheal illness, not neonatal sepsis.

      Group B Streptococcus (GBS) is a common cause of severe infection in newborns. It is estimated that 20-40% of mothers carry GBS in their bowel flora, which can be passed on to their infants during labor and lead to serious infections. Prematurity, prolonged rupture of membranes, previous sibling GBS infection, and maternal pyrexia are all risk factors for GBS infection. The Royal College of Obstetricians and Gynaecologists (RCOG) has published guidelines on GBS management, which include not offering universal screening for GBS to all women and not offering screening based on maternal request. Women who have had GBS detected in a previous pregnancy should be offered intrapartum antibiotic prophylaxis (IAP) or testing in late pregnancy and antibiotics if still positive. IAP should also be offered to women with a previous baby with GBS disease, women in preterm labor, and women with a fever during labor. Benzylpenicillin is the preferred antibiotic for GBS prophylaxis.

    Correct

    • During a routine examination of a woman who is 35 weeks pregnant, she reports feeling short of breath. Which of the following cardiac examination findings would require further evaluation and not be considered normal?

      Your Answer: Pulmonary oedema

      Explanation:

      Physiological Changes During Pregnancy

      The human body undergoes significant physiological changes during pregnancy. The cardiovascular system experiences an increase in stroke volume by 30%, heart rate by 15%, and cardiac output by 40%. However, systolic blood pressure remains unchanged, while diastolic blood pressure decreases in the first and second trimesters, returning to non-pregnant levels by term. The enlarged uterus may interfere with venous return, leading to ankle edema, supine hypotension, and varicose veins.

      The respiratory system sees an increase in pulmonary ventilation by 40%, with tidal volume increasing from 500 to 700 ml due to the effect of progesterone on the respiratory center. Oxygen requirements increase by only 20%, leading to over-breathing and a fall in pCO2, which can cause a sense of dyspnea accentuated by the elevation of the diaphragm. The basal metabolic rate increases by 15%, possibly due to increased thyroxine and adrenocortical hormones, making warm conditions uncomfortable for women.

      The maternal blood volume increases by 30%, mostly in the second half of pregnancy. Red blood cells increase by 20%, but plasma increases by 50%, leading to a decrease in hemoglobin. There is a low-grade increase in coagulant activity, with a rise in fibrinogen and Factors VII, VIII, X. Fibrinolytic activity decreases, returning to normal after delivery, possibly due to placental suppression. This prepares the mother for placental delivery but increases the risk of thromboembolism. Platelet count falls, while white blood cell count and erythrocyte sedimentation rate rise.

      The urinary system experiences an increase in blood flow by 30%, with glomerular filtration rate increasing by 30-60%. Salt and water reabsorption increase due to elevated sex steroid levels, leading to increased urinary protein losses. Trace glycosuria is common due to the increased GFR and reduction in tubular reabsorption of filtered glucose.

      Calcium requirements increase during pregnancy, especially during the third trimester and lactation. Calcium is transported actively across the placenta, while serum levels of calcium and phosphate fall with a fall in protein. Ionized levels of calcium remain stable, and gut absorption of calcium increases substantially due to increased 1,25 dihydroxy vitamin D.

      The liver experiences an increase in alkaline phosphatase by 50%,

    Incorrect

    • A 25-year-old woman had blood tests taken at her 12-week booking appointment with the midwife. This is her first pregnancy and she has no significant medical history. The results of her full blood count (FBC) are as follows:
      - Hb: 110 g/L (normal range for females: 115-160 g/L)
      - Platelets: 340 x 10^9/L (normal range: 150-400 x 10^9/L)
      - WBC: 7.2 x 10^9/L (normal range: 4.0-11.0 x 10^9/L)

      What would be the most appropriate course of action based on these results?

      Your Answer: Check serum ferritin levels

      Correct Answer: Start oral iron replacement therapy

      Explanation:

      To determine if iron supplementation is necessary, a cut-off of 110 g/L should be applied during the first trimester.

      During pregnancy, women are checked for anaemia twice – once at the initial booking visit (usually around 8-10 weeks) and again at 28 weeks. The National Institute for Health and Care Excellence (NICE) has set specific cut-off levels to determine if a pregnant woman requires oral iron therapy. These levels are less than 110 g/L in the first trimester, less than 105 g/L in the second and third trimesters, and less than 100 g/L postpartum.

      If a woman’s iron levels fall below these cut-offs, she will be prescribed oral ferrous sulfate or ferrous fumarate. It is important to continue this treatment for at least three months after the iron deficiency has been corrected to allow the body to replenish its iron stores. By following these guidelines, healthcare professionals can help ensure that pregnant women receive the appropriate care to prevent and manage anaemia during pregnancy.

    Correct

    • A woman experiences a significant post-partum haemorrhage leading to shock. Subsequently, she develops a visual field defect and severe headache. What are the most probable complications that may arise?

      Your Answer: Sheehan’s syndrome

      Explanation:

      Peripartum Complications: Sheehan’s Syndrome, Eclampsia, and Other Causes of Headache and Visual Disturbances

      Peripartum complications can present with a variety of symptoms, including headache and visual disturbances. Sheehan’s syndrome is a condition that results from pituitary infarction due to haemorrhagic shock during labour and the peripartum period. It typically affects the anterior pituitary, leading to hormonal deficiencies that may present acutely or more indolently. Hormone replacement is the mainstay of treatment.

      Eclampsia is another peripartum complication that can cause high blood pressure and seizures, sometimes leading to loss of consciousness. It requires urgent medical attention.

      Other causes of headache and visual disturbances in the peripartum period include subarachnoid haemorrhage, which may present with sudden onset headache and visual disturbances, and extradural haemorrhage, which is typically found in trauma adjacent to fractures of the temporal bone. Occipital haemorrhagic infarction can also cause these symptoms, but a visual field defect is more suggestive of Sheehan’s syndrome.

      It is important for healthcare providers to be aware of these potential complications and to promptly evaluate and manage them to ensure the best possible outcomes for both mother and baby.

    Correct

    • A 30-year-old woman, para 2+ 0, has given birth to a healthy baby. The third stage of labor was actively managed with Syntocinon, cord clamping, and controlled cord traction. The midwives examined the placenta, which appeared complete. However, the woman is experiencing postpartum bleeding and has lost an estimated 1,500 ml of blood. She has no prior medical history. What is the initial pharmacological treatment of choice to stop the bleeding?

      Your Answer: IV syntocinon

      Explanation:

      Postpartum haemorrhage (PPH) caused by uterine atony can be treated with various medical options including oxytocin, ergometrine, carboprost, and misoprostol. Initially, non-pharmacological methods such as bimanual uterine compression and catheter insertion should be used. RCOG guidelines recommend starting with Syntocinon 5 Units by slow IV injection, followed by ergometrine (avoid in hypertension), and then a Syntocinon infusion. Carboprost (avoid in asthma) and misoprostol 1000 micrograms rectally are then recommended. If pharmacological management fails, surgical haemostasis should be initiated. In a major PPH, ABCD management should be initiated, including fluids while waiting for appropriate cross-matched blood. Primary PPH is defined as a loss of greater than 500 ml of blood within 24 hours of delivery, with minor PPH being a loss of 500-1000 ml of blood and major PPH being over 1000 ml of blood. The causes of primary PPH can be categorized into the 4 T’s: Tone, Tissue, Trauma, and Thrombin. Uterine atony is the most common cause of primary PPH.

      Understanding Postpartum Haemorrhage

      Postpartum haemorrhage (PPH) is a condition where a woman experiences blood loss of more than 500 ml after giving birth vaginally. It can be classified as primary or secondary. Primary PPH occurs within 24 hours after delivery and is caused by the 4 Ts: tone, trauma, tissue, and thrombin. The most common cause is uterine atony. Risk factors for primary PPH include previous PPH, prolonged labour, pre-eclampsia, increased maternal age, emergency Caesarean section, and placenta praevia.

      In managing PPH, it is important to involve senior staff immediately and follow the ABC approach. This includes two peripheral cannulae, lying the woman flat, blood tests, and commencing a warmed crystalloid infusion. Mechanical interventions such as rubbing up the fundus and catheterisation are also done. Medical interventions include IV oxytocin, ergometrine, carboprost, and misoprostol. Surgical options such as intrauterine balloon tamponade, B-Lynch suture, ligation of uterine arteries, and hysterectomy may be considered if medical options fail to control the bleeding.

      Secondary PPH occurs between 24 hours to 6 weeks after delivery and is typically due to retained placental tissue or endometritis. It is important to understand the causes and risk factors of PPH to prevent and manage this life-threatening emergency effectively.

    Incorrect

    • A 27-year-old female patient arrives at 38 weeks gestation with a 4-day history of headaches and swelling in her lower limbs. Upon examination, her heart rate is 80 bpm, her blood pressure is 168/86 mmHg, and a urine dipstick reveals proteinuria. While being examined, she experiences a generalized tonic-clonic seizure that resolves on its own. An emergency C-section is planned, and another seizure occurs. What is the best course of action for her treatment?

      Your Answer: Magnesium sulfate until 24 hours after delivery or until seizure stops

      Correct Answer: Magnesium sulfate until 24 hours after last seizure or 24 hours after delivery

      Explanation:

      Magnesium sulfate should be continued for at least 24 hours after delivery or the last seizure in the management of eclampsia. This patient’s condition has progressed to eclampsia, and the primary concern is preventing seizures and delivering the baby. Magnesium sulfate is the preferred agent for managing seizures and providing neuroprotection to the baby. Stopping magnesium sulfate immediately after the last seizure still poses a risk of another seizure occurring, so it should be continued for another 24 hours. Correcting hypertension alone is unlikely to resolve the seizures, so antihypertensive therapy should be given in addition to magnesium sulfate.

      Understanding Eclampsia and its Treatment

      Eclampsia is a condition that occurs when seizures develop in association with pre-eclampsia, a pregnancy-induced hypertension that is characterized by proteinuria and occurs after 20 weeks of gestation. To prevent seizures in patients with severe pre-eclampsia and treat seizures once they develop, magnesium sulphate is commonly used. However, it is important to note that this medication should only be given once a decision to deliver has been made. In cases of eclampsia, an IV bolus of 4g over 5-10 minutes should be given, followed by an infusion of 1g/hour. During treatment, it is crucial to monitor urine output, reflexes, respiratory rate, and oxygen saturations. Respiratory depression can occur, and calcium gluconate is the first-line treatment for magnesium sulphate-induced respiratory depression. Treatment should continue for 24 hours after the last seizure or delivery, as around 40% of seizures occur post-partum. Additionally, fluid restriction is necessary to avoid the potentially serious consequences of fluid overload.

      In summary, understanding the development of eclampsia and its treatment is crucial in managing this potentially life-threatening condition. Magnesium sulphate is the primary medication used to prevent and treat seizures, but it should only be given once a decision to deliver has been made. Monitoring vital signs and urine output is essential during treatment, and calcium gluconate should be readily available in case of respiratory depression. Finally, fluid restriction is necessary to avoid complications associated with fluid overload.

    Correct

    • A 26-year-old female arrives at the emergency department complaining of sporadic abdominal pain and vaginal bleeding. She believes her last menstrual cycle was 8 weeks ago but is uncertain. She has no prior gynecological history and has never been pregnant before. Her vital signs are stable, with a blood pressure of 130/85 mmHg and a pulse rate of 79 bpm. A pregnancy test conducted in the department is positive, and a transvaginal ultrasound confirms a pregnancy in the adnexa with a fetal heartbeat present. What is the most appropriate course of action in this scenario?

      Your Answer: Surgical management - salpingectomy or salpingostomy

      Explanation:

      The patient has a confirmed ectopic pregnancy, which requires definitive treatment even though there is no evidence of rupture. While expectant management may be an option for those without acute symptoms and decreasing beta-HCG levels, close monitoring is necessary and intervention is recommended if symptoms arise or beta-HCG levels increase. If a fetal heartbeat is present, conservative and medical management are unlikely to be successful and may increase the risk of rupture, which is a medical emergency. Therefore, surgical removal of the ectopic is the most appropriate option. If the opposite tube is healthy, salpingectomy may be the preferred choice. However, if the opposite tube is damaged, salpingostomy may be considered to preserve the functional tube and reduce the risk of future infertility.

      Understanding Ectopic Pregnancy

      Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. This condition is characterized by lower abdominal pain and vaginal bleeding, typically occurring 6-8 weeks after the start of the last period. The pain is usually constant and may be felt on one side of the abdomen due to tubal spasm. Vaginal bleeding is usually less than a normal period and may be dark brown in color. Other symptoms may include shoulder tip pain, pain on defecation/urination, dizziness, fainting, or syncope. Breast tenderness may also be reported.

      During examination, abdominal tenderness and cervical excitation may be observed. However, it is not recommended to examine for an adnexal mass due to the risk of rupturing the pregnancy. Instead, a pelvic examination to check for cervical excitation is recommended. In cases of pregnancy of unknown location, serum bHCG levels >1,500 may indicate an ectopic pregnancy. It is important to seek medical attention immediately if ectopic pregnancy is suspected as it can be life-threatening.

You provide information about the combined test. What other blood markers, in addition to nuchal translucency, are measured?

      Your Answer: Beta-human chorionic gonadotrophin (beta-hCG) and pregnancy associated plasma protein A (PAPP-A)

      Explanation:

      NICE updated guidelines on antenatal care in 2021, recommending the combined test for screening for Down’s syndrome between 11-13+6 weeks. The test includes nuchal translucency measurement, serum B-HCG, and pregnancy-associated plasma protein A (PAPP-A). The quadruple test is offered between 15-20 weeks for women who book later in pregnancy. Results are interpreted as either a ‘lower chance’ or ‘higher chance’ of chromosomal abnormalities. If a woman receives a ‘higher chance’ result, she may be offered a non-invasive prenatal screening test (NIPT) or a diagnostic test. NIPT analyzes cell-free fetal DNA in the mother’s blood and has high sensitivity and specificity for detecting chromosomal abnormalities. Private companies offer NIPT screening from 10 weeks gestation.

Upon obstetric examination, her uterus was non-tender, however, her baby was in breech presentation. The foetal heart rate was also normal, and she denied experiencing any contractions during the bleeding episode. What is the recommended next investigation for the most probable diagnosis?

      Your Answer: Transabdominal ultrasound

      Correct Answer: Transvaginal ultrasound

      Explanation:

      Understanding Placenta Praevia

      Placenta praevia is a condition where the placenta is located wholly or partially in the lower uterine segment. It is a relatively rare condition, with only 5% of women having a low-lying placenta when scanned at 16-20 weeks gestation. However, the incidence at delivery is only 0.5%, as most placentas tend to rise away from the cervix.

      There are several factors associated with placenta praevia, including multiparity, multiple pregnancy, and embryos implanting on a lower segment scar from a previous caesarean section. Clinical features of placenta praevia include shock in proportion to visible loss, no pain, a non-tender uterus, abnormal lie and presentation, and a usually normal fetal heart. Coagulation problems are rare, and small bleeds may occur before larger ones.

      Diagnosis of placenta praevia should not involve digital vaginal examination before an ultrasound, as this may provoke severe haemorrhage. The condition is often picked up on routine 20-week abdominal ultrasounds, but the Royal College of Obstetricians and Gynaecologists recommends the use of transvaginal ultrasound for improved accuracy and safety. Placenta praevia is classified into four grades, with grade IV being the most severe, where the placenta completely covers the internal os.

      In summary, placenta praevia is a rare condition that can have serious consequences if not diagnosed and managed appropriately. It is important for healthcare professionals to be aware of the associated factors and clinical features, and to use appropriate diagnostic methods for accurate grading and management.

    • A 29-year-old woman who is 10 weeks pregnant presents to the early pregnancy assessment unit with vaginal bleeding and abdominal pain that started yesterday. She has a history of Von Willebrand disease. A trans-vaginal ultrasound scan confirms a missed miscarriage. The patient is currently stable without fever or hemodynamic instability. What is the most suitable initial approach to manage this patient's miscarriage?

      Your Answer: Vaginal misoprostol

      Explanation:

      The recommended medical management for a miscarriage is the administration of vaginal misoprostol, as stated in the 2018 NICE guidelines. This is particularly suitable for patients with a medical history of coagulopathy, such as Von Willebrand disease, as it is a safer option than expectant management. Oral methotrexate is not appropriate for a miscarriage, as it is used for the medical management of ectopic pregnancies. Salpingectomy is a surgical procedure used for tubular ectopic pregnancies, but not for miscarriages. Vacuum aspiration is a surgical option for miscarriages, but medical management is preferred as it is safer and allows the patient to have more control over the process.

      Management Options for Miscarriage

      Miscarriage can be a difficult and emotional experience for women. In the 2019 NICE guidelines, three types of management for miscarriage were discussed: expectant, medical, and surgical. Expectant management involves waiting for a spontaneous miscarriage and is considered the first-line option. However, if it is unsuccessful, medical or surgical management may be offered.

      Medical management involves using tablets to expedite the miscarriage. Vaginal misoprostol, a prostaglandin analogue, is used to cause strong myometrial contractions leading to the expulsion of tissue. It is important to advise patients to contact their doctor if bleeding does not start within 24 hours. Antiemetics and pain relief should also be given.

      Surgical management involves undergoing a surgical procedure under local or general anaesthetic. The two main options are vacuum aspiration (suction curettage) or surgical management in theatre. Vacuum aspiration is done under local anaesthetic as an outpatient, while surgical management is done in theatre under general anaesthetic. This was previously referred to as ‘Evacuation of retained products of conception’.

      It is important to note that some situations are better managed with medical or surgical management, such as an increased risk of haemorrhage, being in the late first trimester, having coagulopathies or being unable to have a blood transfusion, previous adverse and/or traumatic experience associated with pregnancy, evidence of infection, and more. Ultimately, the management option chosen should be based on the individual patient’s needs and preferences.

    Incorrect

    • A woman at 12 weeks gestation experiences a miscarriage. Out of these five factors, which one is most strongly linked to miscarriage?

      Your Answer: Heavy lifting

      Correct Answer: Obesity

      Explanation:

      Obesity is the only factor among the given options that has been linked to miscarriage. Other factors such as heavy lifting, bumping your tummy, having sex, air travel, and being stressed have not been associated with an increased risk of miscarriage. However, factors like increased maternal age, smoking in pregnancy, consuming alcohol, recreational drug use, high caffeine intake, infections and food poisoning, health conditions, and certain medicines have been linked to an increased risk of miscarriage. Additionally, an unusual shape or structure of the womb and cervical incompetence can also increase the risk of miscarriage.

      Miscarriage: Understanding the Epidemiology

      Miscarriage, also known as abortion, refers to the expulsion of the products of conception before 24 weeks. To avoid any confusion, the term miscarriage is often used. According to epidemiological studies, approximately 15-20% of diagnosed pregnancies will end in miscarriage during early pregnancy. In fact, up to 50% of conceptions may not develop into a blastocyst within 14 days.

      Recurrent spontaneous miscarriage, which is defined as the loss of three or more consecutive pregnancies, affects approximately 1% of women. Understanding the epidemiology of miscarriage is important for healthcare providers and patients alike. It can help to identify risk factors and provide appropriate counseling and support for those who have experienced a miscarriage. By raising awareness and promoting education, we can work towards reducing the incidence of miscarriage and improving the overall health and well-being of women and their families.

    • You are summoned to the Labour Ward to assess a 29-year-old woman who is receiving consultant-led care for gestational diabetes. She was induced at 38+5 weeks’ gestation and has been on oxytocin for augmentation for one hour. She is currently experiencing regular contractions, with six to seven every ten minutes, each lasting at least 45 s. The cervix is dilated to 5 cm. The cardiotocograph (CTG) displays a fetal heart rate baseline of 130 bpm, variability of 20 bpm, accelerations and variable decelerations lasting > 60 s, with a reduced baseline variability in up to 50% of contractions for 30 minutes or more.
      What is the next appropriate step in managing this patient?

      Your Answer: Emergency Caesarean section

      Correct Answer: Reduce the oxytocin infusion rate

      Explanation:

      Management of Uterine Hyperstimulation Syndrome and Suspicious CTG in Labor

      Uterine hyperstimulation syndrome can lead to a suspicious CTG, which requires prompt management to prevent fetal distress. If the patient presents with uterine hyperstimulation syndrome caused by oxytocin infusion, the first step is to reduce the infusion rate and review the CTG in half an hour. If the CTG shows acute bradycardia or prolonged deceleration for more than three minutes, an emergency Caesarean section should be performed if the patient’s cervix is not fully dilated. Instrumental delivery, in the form of forceps or ventouse, is only indicated under certain circumstances, and the patient must be fully dilated. Increasing the oxytocin infusion rate should be avoided as it exacerbates the symptoms of uterine hyperstimulation. When the CTG is normal, no action is required. Early decelerations occur with uterine contractions and are associated with compression of the fetal head during contraction, leading to vagal nerve stimulation and slowing of the fetal heart rate.

      Her past medical history includes hypothyroidism and irritable bowel syndrome. She smokes 6 cigarettes a day. The foetus was conceived via in-vitro fertilisation (IVF).

      On examination, it is found that she has lost 3.2kg, with a pre-pregnancy weight of 64.3kg. Her blood results show the following:

      Na+ 124 mmol/L (135 - 145)
      K+ 3.2 mmol/L (3.5 - 5.0)
      pH 7.46 (7.35-7.45)

      What factors in this patient's history have increased the risk of her presentation?

      Your Answer: Multiple pregnancy

      Explanation:

      Hyperemesis gravidarum, a severe form of nausea and vomiting during pregnancy, can lead to pre-pregnancy weight loss and electrolyte imbalance. Women with multiple pregnancies, such as the patient in this case, are at a higher risk due to elevated levels of the hormone human chorionic gonadotropin (HCG). Hyperthyroidism and molar pregnancy are also risk factors, while hypothyroidism and irritable bowel syndrome are not associated with hyperemesis gravidarum. In-vitro fertilisation (IVF) indirectly increases the risk due to the higher likelihood of multiple pregnancy.

      Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy that occurs in around 1% of pregnancies and is most common between 8 and 12 weeks. It is associated with raised beta hCG levels and can be caused by multiple pregnancies, trophoblastic disease, hyperthyroidism, nulliparity, and obesity. Referral criteria for nausea and vomiting in pregnancy include continued symptoms with ketonuria and/or weight loss, a confirmed or suspected comorbidity, and inability to keep down liquids or oral antiemetics. The diagnosis of hyperemesis gravidarum requires the presence of 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance. Management includes first-line use of antihistamines and oral cyclizine or promethazine, with second-line options of ondansetron and metoclopramide. Admission may be needed for IV hydration. Complications can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth issues.

    • A 36-year-old G5P2 woman comes to antenatal clinic at 35+2 gestation with a history of uneventful pregnancy except for moderate morning sickness in the first trimester. She reports several minor symptoms. What symptoms would require further investigation and raise concern?

      Your Answer: Dysuria

      Explanation:

      While many symptoms experienced during pregnancy are normal and not a cause for concern, it is important to be aware of symptoms that may indicate a medical issue, such as dysuria.

      Dysuria, or painful urination, can be a sign of a urinary tract infection (UTI), which should be treated promptly during any stage of pregnancy. UTIs have been linked to premature birth, as the inflammation caused by the infection can irritate the cervix and trigger preterm labor.

      Fatigue during pregnancy is a common experience and can have multiple causes. In the third trimester, it is considered normal. Lower back pain is also a common symptom, caused by the hormone relaxin increasing laxity in the sacroiliac joints and the added mechanical strain of pregnancy.

      Nausea and vomiting are most commonly experienced in the first trimester, but can still occur throughout pregnancy and are generally considered normal.

      Minor Symptoms of Pregnancy

      During pregnancy, women may experience minor symptoms that are common and not usually a cause for concern. These symptoms may include nausea and vomiting, tiredness, and musculoskeletal pains. Nausea and vomiting, commonly known as morning sickness, can occur at any time of the day and may last throughout the first trimester. Tiredness is also a common symptom, especially during the first and third trimesters. Musculoskeletal pains, such as back pain and pelvic pain, may also occur due to the changes in the body’s structure and weight distribution. While these symptoms may be uncomfortable, they are typically manageable and can be relieved with rest, exercise, and proper nutrition. It is important to consult with a healthcare provider if these symptoms become severe or persistent.

    • A 30-year-old woman in the delivery room experienced a primary postpartum hemorrhage (PPH) 3 hours after delivery. Following adequate resuscitation, she was assessed and diagnosed with uterine atony as the underlying cause. Pharmacological treatment was initiated, but proved ineffective. What is the most suitable initial surgical intervention?

      Your Answer: Intrauterine balloon tamponade

      Explanation:

      The majority of cases of postpartum hemorrhage are caused by uterine atony, while trauma, retained placenta, and coagulopathy account for the rest. According to the 2009 RCOG guidelines, if pharmacological management fails to stop bleeding and uterine atony is the perceived cause, surgical intervention should be attempted promptly. Intrauterine balloon tamponade is the recommended first-line measure for most women, but other interventions may also be considered depending on the clinical situation and available expertise. These interventions include haemostatic brace suturing, bilateral ligation of uterine arteries, bilateral ligation of internal iliac (hypogastric) arteries, selective arterial embolization, and hysterectomy.

      Understanding Postpartum Haemorrhage

      Postpartum haemorrhage (PPH) is a condition where a woman experiences blood loss of more than 500 ml after giving birth vaginally. It can be classified as primary or secondary. Primary PPH occurs within 24 hours after delivery and is caused by the 4 Ts: tone, trauma, tissue, and thrombin. The most common cause is uterine atony. Risk factors for primary PPH include previous PPH, prolonged labour, pre-eclampsia, increased maternal age, emergency Caesarean section, and placenta praevia.

      In managing PPH, it is important to involve senior staff immediately and follow the ABC approach. This includes two peripheral cannulae, lying the woman flat, blood tests, and commencing a warmed crystalloid infusion. Mechanical interventions such as rubbing up the fundus and catheterisation are also done. Medical interventions include IV oxytocin, ergometrine, carboprost, and misoprostol. Surgical options such as intrauterine balloon tamponade, B-Lynch suture, ligation of uterine arteries, and hysterectomy may be considered if medical options fail to control the bleeding.

      Secondary PPH occurs between 24 hours to 6 weeks after delivery and is typically due to retained placental tissue or endometritis. It is important to understand the causes and risk factors of PPH to prevent and manage this life-threatening emergency effectively.

    Incorrect

    • A 30-year-old woman is being seen on the postnatal ward 3 days after an uncomplicated, elective lower-segment caesarean section. This is her first child and she is eager to exclusively breastfeed. Her lochia is normal and she is able to move around independently. She is scheduled to be discharged later in the day and is interested in starting contraception right away. She has previously used both the combined oral contraceptive pill and an intrauterine device, both of which worked well for her. What options should be presented to her?

      Your Answer: Intrauterine device fitting in hospital before she is discharged

      Correct Answer: Progesterone-only pill to start immediately

      Explanation:

      Women who have recently given birth, whether they are breastfeeding or not, can begin taking the progesterone-only pill at any time. However, for this patient who is only 2 days postpartum, it is recommended to prescribe the progesterone-only pill as it does not contain estrogen and is less likely to affect milk production. Additionally, it does not increase the risk of venous thromboembolism, which is a concern for postpartum women until 21-28 days after giving birth. The combined oral contraceptive pill should be avoided until 21 days postpartum due to the risk of thrombosis and reduced breast milk production. The patient cannot resume her previous contraceptives at this time. While an intrauterine device can be inserted during a caesarean section, it is advisable to wait 4-6 weeks postpartum before having it inserted vaginally. It is incorrect to tell the patient that she cannot use any contraception if she wishes to breastfeed, as the progesterone-only pill has been shown to have minimal effect on milk production in breastfeeding women.

      After giving birth, women need to use contraception after 21 days. The progesterone-only pill (POP) can be started at any time postpartum, according to the FSRH. Additional contraception should be used for the first two days after day 21. A small amount of progesterone enters breast milk, but it is not harmful to the infant. On the other hand, the combined oral contraceptive pill (COCP) is absolutely contraindicated (UKMEC 4) if breastfeeding is less than six weeks post-partum. If breastfeeding is between six weeks and six months postpartum, it is a UKMEC 2. The COCP may reduce breast milk production in lactating mothers. It should not be used in the first 21 days due to the increased venous thromboembolism risk post-partum. After day 21, additional contraception should be used for the first seven days. The intrauterine device or intrauterine system can be inserted within 48 hours of childbirth or after four weeks.

      The lactational amenorrhoea method (LAM) is 98% effective if the woman is fully breastfeeding (no supplementary feeds), amenorrhoeic, and less than six months post-partum. It is important to note that an inter-pregnancy interval of less than 12 months between childbirth and conceiving again is associated with an increased risk of preterm birth, low birth weight, and small for gestational age babies.

    Correct

    • A 30-year-old primiparous woman who is 10 weeks pregnant is curious about iron supplementation. Her blood tests reveal a Hb level of 110 g/L. What is the appropriate Hb cut-off for initiating treatment in this patient?

      Your Answer: 110

      Explanation:

      During pregnancy, women are checked for anaemia twice – once at the initial booking visit (usually around 8-10 weeks) and again at 28 weeks. The National Institute for Health and Care Excellence (NICE) has set specific cut-off levels to determine if a pregnant woman requires oral iron therapy. These levels are less than 110 g/L in the first trimester, less than 105 g/L in the second and third trimesters, and less than 100 g/L postpartum.

      If a woman’s iron levels fall below these cut-offs, she will be prescribed oral ferrous sulfate or ferrous fumarate. It is important to continue this treatment for at least three months after the iron deficiency has been corrected to allow the body to replenish its iron stores. By following these guidelines, healthcare professionals can help ensure that pregnant women receive the appropriate care to prevent and manage anaemia during pregnancy.
