    Incorrect

    • A 19-year-old female patient has visited her doctor seeking advice on changing her current contraceptive pill due to concerns about its effectiveness. She wants to know the safest option available to minimize the risk of pregnancy.

      What would be the most appropriate contraceptive to recommend?

      Your Answer: Combined oral contraceptive pill

      Correct Answer: Progesterone implant

      Explanation:

      According to research, the contraceptive implant is the most reliable method of birth control, with the exception of abstinence. The intrauterine device (IUD) and depot injections are equally effective as the implant. However, oral contraceptive pills are not as dependable as implanted or injected medications.

      Implanon and Nexplanon are both subdermal contraceptive implants that slowly release the hormone etonogestrel to prevent ovulation and thicken cervical mucus. Nexplanon is an updated version of Implanon with a redesigned applicator to prevent deep insertions and is radiopaque for easier location. It is highly effective with a failure rate of 0.07/100 women-years and lasts for 3 years. It does not contain estrogen, making it suitable for women with a history of thromboembolism or migraines. It can be inserted immediately after a termination of pregnancy. However, a trained professional is needed for insertion and removal, and additional contraception is required for the first 7 days if not inserted on days 1-5 of the menstrual cycle.

      The main disadvantage of these implants is irregular and heavy bleeding, which can be managed with a co-prescription of the combined oral contraceptive pill. Other adverse effects include headache, nausea, and breast pain. Enzyme-inducing drugs may reduce the efficacy of Nexplanon, and women should switch to a different method or use additional contraception until 28 days after stopping the treatment. Contraindications include ischaemic heart disease/stroke, unexplained vaginal bleeding, past breast cancer, severe liver cirrhosis, and liver cancer. Breast cancer is a UKMEC 4 condition, meaning it represents an unacceptable risk if the contraceptive method is used.

    Incorrect

    • A 28-year-old woman, who is 10 weeks pregnant with twins, presents to the emergency department with worsening nausea and vomiting over the last 3 weeks. This is her second pregnancy. Her first pregnancy had several complications, including hypertension of pregnancy and delivering a large for gestational age baby. What is a significant risk factor for developing HG based on this history?

      Your Answer: Pre-eclampsia

      Correct Answer: Multiple pregnancy

      Explanation:

      Hyperemesis gravidarum (HG) is a condition characterized by persistent vomiting, dehydration, weight loss, and electrolyte imbalance, often accompanied by ketosis. Women with multiple pregnancies are at an increased risk of developing HG due to the higher concentrations of pregnancy-related hormones.

      Other risk factors for HG include trophoblastic disease, molar pregnancy, and a history of previous hyperemesis. Hypertension of pregnancy typically occurs after 16 weeks and is not associated with an increased risk of HG.

      Large for gestational age is not a risk factor for HG as it is usually diagnosed later in pregnancy during growth scans. Multiparity alone is not a risk factor, but a history of previous hyperemesis or nausea and vomiting during pregnancy increases the risk.

      Hyperemesis gravidarum is a severe form of nausea and vomiting that affects around 1% of pregnancies. It is usually experienced between 8 and 12 weeks of pregnancy but can persist up to 20 weeks. The condition is thought to be related to raised beta hCG levels and is more common in women who are obese, nulliparous, or have multiple pregnancies, trophoblastic disease, or hyperthyroidism. Smoking is associated with a decreased incidence of hyperemesis.

      The Royal College of Obstetricians and Gynaecologists recommend that a woman must have a 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance before a diagnosis of hyperemesis gravidarum can be made. Validated scoring systems such as the Pregnancy-Unique Quantification of Emesis (PUQE) score can be used to classify the severity of NVP.

      Management of hyperemesis gravidarum involves using antihistamines as a first-line treatment, with oral cyclizine or oral promethazine being recommended by Clinical Knowledge Summaries. Oral prochlorperazine is an alternative, while ondansetron and metoclopramide may be used as second-line treatments. Ginger and P6 (wrist) acupressure can be tried, but there is little evidence of benefit. Admission may be needed for IV hydration.

      Complications of hyperemesis gravidarum can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth restriction, pre-term birth, and cleft lip/palate (if ondansetron is used during the first trimester). The NICE Clinical Knowledge Summaries recommend considering admission if a woman is unable to keep down liquids or oral antiemetics, has ketonuria and/or weight loss (greater than 5% of body weight), or has a confirmed or suspected comorbidity that may be adversely affected by nausea and vomiting.

    Incorrect

    • A 25-year-old woman is seeking information about the combined oral contraceptive pill for contraception purposes. She has concerns about the pill causing cancer and wants to know more about its potential risks. What advice can you provide her?

      Your Answer: There is no evidence that the combined oral contraceptive pill causes increased risk of cancer

      Correct Answer: The combined oral contraceptive pill increases the risk of breast and cervical cancer but is protective against ovarian and endometrial cancer

      Explanation:

      The combined oral contraceptive pill has been found to have a slightly higher risk of breast cancer, but it is protective against ovarian and endometrial cancer. Women with known breast cancer mutations like BRCA1 should avoid taking the pill as the risk may outweigh the benefits. Additionally, women with current breast cancer should not take the pill. After 5 years of use, there is a small increase in cervical cancer risk, which doubles after 10 years. However, cervical cancer is not a reason to avoid using the pill.

      Pros and Cons of the Combined Oral Contraceptive Pill

      The combined oral contraceptive pill is a highly effective method of birth control with a failure rate of less than one per 100 woman years. It is a convenient option that does not interfere with sexual activity and its contraceptive effects are reversible upon stopping. Additionally, it can make periods regular, lighter, and less painful, and may reduce the risk of ovarian, endometrial, and colorectal cancer. It may also protect against pelvic inflammatory disease, ovarian cysts, benign breast disease, and acne vulgaris.

      However, there are also some disadvantages to consider. One of the main drawbacks is that people may forget to take it, which can reduce its effectiveness. It also offers no protection against sexually transmitted infections, so additional precautions may be necessary. There is an increased risk of venous thromboembolic disease, breast and cervical cancer, stroke, and ischaemic heart disease, especially in smokers. Temporary side effects such as headache, nausea, and breast tenderness may also be experienced.

      Despite some reports of weight gain, a Cochrane review did not find a causal relationship between the combined oral contraceptive pill and weight gain. Overall, the combined oral contraceptive pill can be a safe and effective option for birth control, but it is important to weigh the pros and cons and discuss any concerns with a healthcare provider.

  • Question 4 - What is an accurate depiction of the proliferative phase during the menstrual cycle?...

    Correct

    • What is an accurate depiction of the proliferative phase during the menstrual cycle?

      Your Answer: Oestrogen produced by the follicle results in the thickening of the endometrium and the formation of spiral arteries and glands

      Explanation:

      The proliferative phase is characterized by the thickening of the endometrium due to the presence of oestrogen secreted by the mature follicle.

      As oestrogen levels rise during this phase, the endometrium undergoes proliferation and thickening. Tubular glands extend and spiral arteries form, leading to increased vascularity. Additionally, oestrogen stimulates progesterone receptors on endometrial cells.

      Phases of the Menstrual Cycle

      The menstrual cycle is a complex process that can be divided into four phases: menstruation, follicular phase, ovulation, and luteal phase. During the follicular phase, a number of follicles develop in the ovaries, with one follicle becoming dominant around the mid-follicular phase. At the same time, the endometrium undergoes proliferation. This phase is characterized by a rise in follicle-stimulating hormone (FSH), which results in the development of follicles that secrete oestradiol. When the egg has matured, it secretes enough oestradiol to trigger the acute release of luteinizing hormone (LH), which leads to ovulation.

      During the luteal phase, the corpus luteum secretes progesterone, which causes the endometrium to change to a secretory lining. If fertilization does not occur, the corpus luteum will degenerate, and progesterone levels will fall. Oestradiol levels also rise again during the luteal phase. Cervical mucus thickens and forms a plug across the external os following menstruation. Just prior to ovulation, the mucus becomes clear, acellular, low viscosity, and stretchy. Under the influence of progesterone, it becomes thick, scant, and tacky. Basal body temperature falls prior to ovulation due to the influence of oestradiol and rises following ovulation in response to higher progesterone levels. Understanding the phases of the menstrual cycle is important for women’s health and fertility.

    Incorrect

    • A 10-year-old boy is being released from the hospital following an episode of acute testicular pain. The cause of his admission was an anatomical abnormality related to the processus vaginalis. What is the probable diagnosis?

      Your Answer: Epididymitis

      Correct Answer: Testicular torsion

      Explanation:

      The gubernaculum is responsible for assisting the testicles in descending from the abdomen to the scrotum, while the processus vaginalis precedes this descent and then closes. Abnormalities such as a patent processus vaginalis, also known as bell clapper deformity, can increase the risk of testicular torsion. Nutcracker syndrome occurs when the left renal vein is compressed between the superior mesenteric artery and the aorta, leading to a varicocele due to the left gonadal vein draining into the left renal vein. Acute testicular pain may be caused by epididymitis or mumps orchitis, but these conditions are not related to defects in the processus vaginalis. Signs of bowel obstruction may indicate an incarcerated inguinal hernia.

      The Development of Testicles in Foetal Life

      During foetal life, the testicles are situated within the abdominal cavity. They are initially found on the posterior abdominal wall, at the same level as the upper lumbar vertebrae. The gubernaculum testis, which is attached to the inferior aspect of the testis, extends downwards to the inguinal region and through the canal to the superficial skin. Both the testis and the gubernaculum are located outside the peritoneum.

      As the foetus grows, the gubernaculum becomes progressively shorter. It carries the peritoneum of the anterior abdominal wall, known as the processus vaginalis. The testis is guided by the gubernaculum down the posterior abdominal wall and the back of the processus vaginalis into the scrotum. By the third month of foetal life, the testes are located in the iliac fossae, and by the seventh month, they lie at the level of the deep inguinal ring.

      After birth, the processus vaginalis usually closes, but it may persist and become the site of indirect hernias. Partial closure may also lead to the development of cysts on the cord.

    Incorrect

    • A 35-year-old pregnant woman presents for her initial prenatal visit. She has a history of four previous pregnancies and is a smoker. Her body mass index is 33kg/m² and her blood pressure is 135/80 mmHg. Considering the number of risk factors she has, what is the most suitable approach to managing her pregnancy?

      Your Answer: Commence low molecular weight heparin from week 28 and continue 6 weeks postnatal

      Correct Answer: Commence low molecular weight heparin immediately and continue 6 weeks postnatal

      Explanation:

      A pregnant woman who has 3 risk factors should receive LMWH from 28 weeks until 6 weeks after giving birth. If she has more than 3 risk factors, she should start LMWH immediately and continue until 6 weeks postnatal.

      The risk factors for thromboprophylaxis include age over 35, a body mass index over 30, parity over 3, smoking, gross varicose veins, current pre-eclampsia, immobility, family history of unprovoked VTE, low risk thrombophilia, multiple pregnancy, and IVF pregnancy.

      In this particular case, the woman has 4 risk factors, including being 36 years old, a smoker, having a parity over 3, and a body mass index of 33. Therefore, she needs to begin taking low molecular weight heparin immediately and continue until 6 weeks after giving birth.

      While all pregnant women should be advised to stay mobile and hydrated, this woman requires medical treatment due to her increased risk factors.

      Pregnancy increases the risk of developing venous thromboembolism (VTE), which is why it is important to assess a woman’s individual risk during pregnancy and take appropriate prophylactic measures. A risk assessment should be conducted at the time of booking and on any subsequent hospital admission. Women with a previous VTE history are automatically considered high risk and require low molecular weight heparin throughout the antenatal period, along with input from experts. Women at intermediate risk due to hospitalization, surgery, comorbidities, or thrombophilia should also be considered for antenatal prophylactic low molecular weight heparin.

      The risk assessment at booking should include factors that increase the likelihood of developing VTE, such as age over 35, body mass index over 30, parity over 3, smoking, gross varicose veins, current pre-eclampsia, immobility, family history of unprovoked VTE, low-risk thrombophilia, multiple pregnancy, and IVF pregnancy. If a woman has four or more risk factors, immediate treatment with low molecular weight heparin should be initiated and continued until six weeks postnatal. If a woman has three risk factors, low molecular weight heparin should be initiated from 28 weeks and continued until six weeks postnatal.

      If a diagnosis of DVT is made shortly before delivery, anticoagulation treatment should be continued for at least three months, as in other patients with provoked DVTs. Low molecular weight heparin is the preferred treatment for VTE prophylaxis in pregnancy, while Direct Oral Anticoagulants (DOACs) and warfarin should be avoided. By taking these measures, the risk of developing VTE during pregnancy can be reduced.

    • A 25-year-old woman who is 36 weeks pregnant presents to the hospital with a blood pressure reading of 160/110 mmHg, proteinuria, headache, blurred vision, and abdominal pain. What typical feature would be anticipated in this scenario?

      Your Answer: Bradycardia, hypertension and respiratory irregularity

      Correct Answer: Haemolysis, elevated liver enzymes and low platelets

      Explanation:

      The patient’s medical history suggests pre-eclampsia, which is characterized by high blood pressure and protein in the urine after 20 weeks of pregnancy. antihypertensive medication should be used to manage blood pressure. Women with this condition may also develop HELLP syndrome, which is characterized by low platelets, elevated liver enzymes, and haemolysis (indicated by raised LDH levels). If left untreated, pre-eclampsia can progress to eclampsia, which can be prevented by administering magnesium sulphate. Delivery is the only definitive treatment for pre-eclampsia.

      Symptoms of shock include tachycardia and hypotension, while Cushing’s triad (bradycardia, hypertension, and respiratory irregularity) is indicative of raised intracranial pressure. Anaphylaxis is characterized by facial swelling, rash, and stridor, while sepsis may present with warm extremities, rigors, and a strong pulse.

      Jaundice During Pregnancy

      During pregnancy, jaundice can occur due to various reasons. One of the most common liver diseases during pregnancy is intrahepatic cholestasis of pregnancy, which affects around 1% of pregnancies and is usually seen in the third trimester. Symptoms include itching, especially in the palms and soles, and raised bilirubin levels. Ursodeoxycholic acid is used for symptomatic relief, and women are typically induced at 37 weeks. However, this condition can increase the risk of stillbirth.

      Acute fatty liver of pregnancy is a rare complication that can occur in the third trimester or immediately after delivery. Symptoms include abdominal pain, nausea, vomiting, headache, jaundice, and hypoglycemia. ALT levels are typically elevated. Supportive care is the initial management, and delivery is the definitive management once the patient is stabilized.

      Gilbert’s and Dubin-Johnson syndrome may also be exacerbated during pregnancy. Additionally, HELLP syndrome, which stands for Haemolysis, Elevated Liver enzymes, Low Platelets, can also cause jaundice during pregnancy. It is important to monitor liver function tests and seek medical attention if any symptoms of jaundice occur during pregnancy.

    Incorrect

    • A 55-year-old woman comes to the clinic with a lump in the upper outer quadrant of her left breast. Which of the following statements about the breast is false?

      Your Answer: None of the above

      Correct Answer: Nipple retraction may occur as a result of tumour infiltration of the clavipectoral fascia

      Explanation:

      Breast malignancy often leads to skin dimpling and nipple retraction, which are caused by the tumour infiltrating the breast ligaments and ducts. The axillary contents are enclosed by the clavipectoral fascia, and the breast’s lymphatic drainage occurs in both the axilla and internal mammary chain. The breast is highly vascularized, with the internal mammary artery being a subclavian artery branch.

      The breast is situated on a layer of pectoral fascia and is surrounded by the pectoralis major, serratus anterior, and external oblique muscles. The nerve supply to the breast comes from branches of intercostal nerves from T4-T6, while the arterial supply comes from the internal mammary (thoracic) artery, external mammary artery (laterally), anterior intercostal arteries, and thoraco-acromial artery. The breast’s venous drainage is through a superficial venous plexus to subclavian, axillary, and intercostal veins. Lymphatic drainage occurs through the axillary nodes, internal mammary chain, and other lymphatic sites such as deep cervical and supraclavicular fossa (later in disease).

      The preparation for lactation involves the hormones oestrogen, progesterone, and human placental lactogen. Oestrogen promotes duct development in high concentrations, while high levels of progesterone stimulate the formation of lobules. Human placental lactogen prepares the mammary glands for lactation. The two hormones involved in stimulating lactation are prolactin and oxytocin. Prolactin causes milk secretion, while oxytocin causes contraction of the myoepithelial cells surrounding the mammary alveoli to result in milk ejection from the breast. Suckling of the baby stimulates the mechanoreceptors in the nipple, resulting in the release of both prolactin and oxytocin from the pituitary gland (anterior and posterior parts respectively).

    Correct

    • A 35-year-old woman presents with sudden onset of shortness of breath 3 hours after giving birth. The delivery was uncomplicated. On examination, her pulse is 120/min, blood pressure is 160/100 mmHg, and respirations are 24/min. Diffuse crackles are heard in all lung fields and pulse oximetry shows 85%. A chest x-ray reveals a peripheral wedge-shaped opacity. Despite appropriate interventions, she passes away. Autopsy findings reveal fetal squamous cells in the pulmonary blood vessels.

      What is the most likely diagnosis?

      Your Answer: Amniotic fluid embolism

      Explanation:

      The presence of fetal squamous cells in the maternal blood vessels of a woman who died during or after labor suggests that she had amniotic fluid embolism instead of pulmonary thromboembolism.

      The patient displayed symptoms of pulmonary embolism shortly after giving birth, including acute shortness of breath, tachycardia, and tachypnea, as well as a wedge-shaped infarction on her chest x-ray. The resulting hypoventilation caused hypoxia. Given that pregnancy is a hypercoagulable state, there is an increased risk of thrombus formation and subsequent embolization, making pulmonary thromboembolism the primary differential diagnosis.

      However, the histological findings during autopsy confirmed that the woman had amniotic fluid embolism, as fetal squamous cells were found in her maternal blood vessels. The risk of fetal and maternal blood mixing is highest during the third trimester and delivery, and fetal cells can act as thrombogenic factors. Although rare, this condition has a high mortality rate, and even those who survive often experience severe deficits, including neurological damage.

      Fat embolism typically occurs after long bone fractures or orthopedic surgeries, while air embolism is very rare but can cause immediate death. Cholesterol embolization is a common scenario after cannulation, such as angiography, where the catheter mechanically displaces the cholesterol thrombus, leading to emboli.

      Amniotic Fluid Embolism: A Rare but Life-Threatening Complication of Pregnancy

      Amniotic fluid embolism is a rare but potentially fatal complication of pregnancy that occurs when fetal cells or amniotic fluid enter the mother’s bloodstream, triggering a severe reaction. Although many risk factors have been associated with this condition, such as maternal age and induction of labor, the exact cause remains unknown. 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 occur during labor, but they can also occur during cesarean section or in the immediate postpartum period. Symptoms of amniotic fluid embolism include chills, shivering, sweating, anxiety, and coughing, while signs include cyanosis, hypotension, bronchospasms, tachycardia, arrhythmia, and myocardial infarction. However, there are no definitive diagnostic tests for this condition, and diagnosis is usually made by excluding other possible causes of the patient’s symptoms.

      Management of amniotic fluid embolism requires immediate critical care by a multidisciplinary team, as the condition can be life-threatening. Treatment is primarily supportive, and the focus is on stabilizing the patient’s vital signs and providing respiratory and cardiovascular support as needed. Despite advances in medical care, the mortality rate associated with amniotic fluid embolism remains high, underscoring the need for continued research into the underlying causes and potential treatments for this rare but serious complication of pregnancy.

    Correct

    • A 65-year-old female presents to you with a complaint of urinary incontinence whenever she coughs or sneezes. She has a history of obesity and has given birth to five children, four of which were vaginal deliveries and one by caesarean section. A negative urinary dipstick is noted, but a vaginal examination reveals some muscle weakness without prolapse. The most probable diagnosis is stress incontinence. What is the most appropriate initial management option for this patient?

      Your Answer: Pelvic muscle floor training

      Explanation:

      First-line treatment for urinary incontinence is bladder retraining for urge incontinence and pelvic floor muscle training for stress incontinence. Surgery is a later option. Toileting aids and decreasing fluid intake should not be advised. Patients should drink 6-8 glasses of water per day.

      Urinary incontinence is a common condition that affects approximately 4-5% of the population, with elderly females being more susceptible. There are several risk factors that can contribute to the development of urinary incontinence, including advancing age, previous pregnancy and childbirth, high body mass index, hysterectomy, and family history. The condition can be classified into different types, such as overactive bladder, stress incontinence, mixed incontinence, overflow incontinence, and functional incontinence.

      Initial investigation of urinary incontinence involves completing bladder diaries for at least three days, performing a vaginal examination to exclude pelvic organ prolapse, and conducting urine dipstick and culture tests. Urodynamic studies may also be necessary. Management of urinary incontinence depends on the predominant type of incontinence. For urge incontinence, bladder retraining and bladder stabilizing drugs such as antimuscarinics are recommended. For stress incontinence, pelvic floor muscle training and surgical procedures may be necessary. Duloxetine, a combined noradrenaline and serotonin reuptake inhibitor, may also be offered to women who decline surgical procedures.

      In summary, urinary incontinence is a common condition that can be caused by various risk factors. It can be classified into different types, and management depends on the predominant type of incontinence. Initial investigation involves completing bladder diaries, performing a vaginal examination, and conducting urine tests. Treatment options include bladder retraining, bladder stabilizing drugs, pelvic floor muscle training, surgical procedures, and duloxetine.
