A 27-year-old woman visits her GP with complaints of itchy eyes. She reports a sensation of grittiness in both eyes and observes that they stick together in the morning. The grittiness is most severe upon waking up. She denies experiencing any other symptoms.
What is the probable diagnosis based on her presentation?Your Answer: Blepharitis
Explanation:The patient is experiencing bilateral grittiness that is worse in the mornings and sticking eyelids, which is a classic symptom of blepharitis. Dry eye syndrome, which is more common in the elderly, can also cause a bilateral gritty feeling, but symptoms are typically worse at the end of the day and may be associated with pain. Cellulitis, on the other hand, would present with redness, inflammation, tenderness, and signs of infection such as fever or discharge. A basal cell carcinoma (BCC) of the eyelid may cause a gritty feeling in the eye, but it would be unilateral, not bilateral. Allergic rhinitis (hay fever) may also cause itchy eyes, but other symptoms such as sneezing, a runny nose, and an itchy nose are typically present.
Blepharitis is a condition where the eyelid margins become inflamed. This can be caused by dysfunction of the meibomian glands (posterior blepharitis) or seborrhoeic dermatitis/staphylococcal infection (anterior blepharitis). It is more common in patients with rosacea. The meibomian glands secrete oil to prevent rapid evaporation of the tear film, so any problem affecting these glands can cause dryness and irritation of the eyes. Symptoms of blepharitis are usually bilateral and include grittiness, discomfort around the eyelid margins, sticky eyes in the morning, and redness of the eyelid margins. Styes and chalazions are also more common in patients with blepharitis, and secondary conjunctivitis may occur.
Management of blepharitis involves softening the lid margin with hot compresses twice a day and practicing lid hygiene to remove debris from the lid margins. This can be done using cotton wool buds dipped in a mixture of cooled boiled water and baby shampoo or sodium bicarbonate in cooled boiled water. Artificial tears may also be given for symptom relief in people with dry eyes or an abnormal tear film.

A 50-year-old woman presents to her General Practitioner with widespread pain for the past month. The pain radiates all over but is worse in her shoulders, neck and lower back. It tends to be worse in the mornings and in cold weather. She reports that she is not able to sleep and feels lethargic during the day. Her partner reports that she has been more forgetful recently. She has otherwise been well without recent illnesses. On examination, there is clear tenderness to the affected areas. There are no other significant findings.
Which of the following is an appropriate first-line treatment for this patient?Your Answer: Pregabalin
Correct Answer: Aerobic exercise
Explanation:Treatment Options for Fibromyalgia Patients
Fibromyalgia is a chronic condition that causes widespread pain, increased sensitivity to pain, and psychological symptoms. Treatment options can be divided into generic and patient-focused treatments. Aerobic exercise is a first-line, generic treatment that has been shown to improve symptoms of pain and physical function. Cognitive behavioral therapy (CBT) is a patient-focused treatment that may be considered for patients with pain-related depression, anxiety, catastrophizing, and/or passive or active coping strategies. Anaerobic exercise should be avoided as it may increase inflammation and oxidative stress. Duloxetine and pregabalin are pharmacotherapy options for patients with severe pain or sleep disturbance, but only after non-pharmacological treatments have failed. It is important to tailor treatment to each patient’s individual needs.

A 5-year-old girl is brought to the emergency department by her father. The father seems hesitant for his child to be examined, and admits he has some distrust towards modern medicine. His daughter has not received any of her routine immunisations. He explains that his daughter was slightly unwell with cold symptoms and a mild cough last week, but her condition has worsened over the past 10 days. Her cough has become so severe that she experiences uncontrollable coughing fits, which have caused her lips to turn blue and led to vomiting. Her symptoms are particularly severe at night.
What is the most appropriate class of antibiotics to prescribe for this patient, given the most likely diagnosis?Your Answer: Tetracycline antibiotics
Correct Answer: Macrolide antibiotics
Explanation:Whooping cough, caused by Bordetella pertussis, can be treated with macrolide antibiotics such as azithromycin or clarithromycin. This infection typically has an incubation period of 5-10 days (maximum 21 days) before the onset of symptoms such as a mild cough, low-grade fever, and coryzal symptoms. The paroxysmal phase follows, characterized by clusters of rapid coughs, a high-pitched whoop, cyanosis, vomiting, and exhaustion. Patients are infectious from the onset of the catarrhal phase until 3 weeks after the start of the paroxysmal phase. Antibiotics are only indicated if the patient presents within 3 weeks of onset of the paroxysmal phase.
Whooping Cough: Causes, Symptoms, Diagnosis, and Management
Whooping cough, also known as pertussis, is a contagious disease caused by the bacterium Bordetella pertussis. It is commonly found in children, with around 1,000 cases reported annually in the UK. The disease is characterized by a persistent cough that can last up to 100 days, hence the name cough of 100 days.
Infants are particularly vulnerable to whooping cough, which is why routine immunization is recommended at 2, 3, 4 months, and 3-5 years. However, neither infection nor immunization provides lifelong protection, and adolescents and adults may still develop the disease.
Whooping cough has three phases: the catarrhal phase, the paroxysmal phase, and the convalescent phase. The catarrhal phase lasts around 1-2 weeks and presents symptoms similar to a viral upper respiratory tract infection. The paroxysmal phase is characterized by a severe cough that worsens at night and after feeding, and may be accompanied by vomiting and central cyanosis. The convalescent phase is when the cough subsides over weeks to months.
To diagnose whooping cough, a person must have an acute cough that has lasted for 14 days or more without another apparent cause, and have one or more of the following features: paroxysmal cough, inspiratory whoop, post-tussive vomiting, or undiagnosed apnoeic attacks in young infants. A nasal swab culture for Bordetella pertussis is used to confirm the diagnosis, although PCR and serology are increasingly used.
Infants under 6 months with suspected pertussis should be admitted, and in the UK, pertussis is a notifiable disease. An oral macrolide, such as clarithromycin, azithromycin, or erythromycin, is indicated if the onset of the cough is within the previous 21 days to eradicate the organism and reduce the spread. Household contacts should be offered antibiotic prophylaxis, although antibiotic therapy has not been shown to alter the course of the illness. School exclusion is recommended for 48 hours after commencing antibiotics or 21 days from onset of symptoms if no antibiotics are given.
Complications of whooping cough include subconjunctival haemorrhage, pneumonia, bronchiectasis, and

A 50-year-old woman comes to the clinic complaining of a painful and swollen hand. She reports having a fracture in her radius that was treated with a plaster cast for four weeks. Since then, she has noticed tenderness and shiny skin in the affected hand. What is the most probable diagnosis for her symptoms?
Your Answer:
Correct Answer: Complex regional pain syndrome
Explanation:Complex Regional Pain Syndromes (CRPS)
Complex Regional Pain Syndromes (CRPS) are a group of conditions that are characterized by localized or widespread pain, accompanied by swelling, changes in skin color and temperature, and disturbances in blood flow. People with CRPS may also experience allodynia (pain from stimuli that are not normally painful), hyperhidrosis (excessive sweating), and changes in nail or hair growth. In some cases, motor abnormalities such as tremors, muscle spasms, and involuntary movements may also occur. Contractures, or the shortening and tightening of muscles, may develop in later stages of the condition. CRPS can affect any part of the body, but it is most commonly seen in the limbs.
One of the defining features of CRPS is that it often develops after an injury, even one that may seem minor or insignificant. Symptoms may not appear until several months after the initial injury. CRPS was previously known as Reflex Sympathetic Dystrophy (RSD).

A 30-year-old woman patient presents with a subacute history of lethargy and low-grade fever. Among other findings, full clinical examination reveals retinal haemorrhages with pale centres, painful red raised lesions on the hands and feet and subcentimetre, non-tender, raised papules on the palms and soles of the feet.
What is the underlying condition?Your Answer:
Correct Answer: Endocarditis
Explanation:Clinical Signs and Diagnosis of Subacute Bacterial Endocarditis
Subacute bacterial endocarditis (SBE) is a condition caused by Streptococcus viridans, an oral commensal, and presents with malaise, weakness, and low-grade fever. Diagnosis is often delayed due to non-specific presentation, but it should be suspected in any febrile or unwell patient with a new or changing murmur. The three classic clinical signs of SBE are finger clubbing, Roth spots, and Osler’s nodes, along with Janeway lesions, which are subcentimeter, non-tender, raised papules on the palms and soles of the feet. Confirmation of SBE usually requires three separate sets of blood cultures taken in a 24-hour period, ideally during times the patient is febrile.
While Janeway lesions may be found in systemic lupus erythaematosus (SLE), the combination of the three described findings is unique to SBE. Tuberculosis does not present with the above constellation of findings but would be expected to present with chronic cough, haemoptysis, fever, and night sweats. Subacute meningococcal septicaemia typically gives a non-blanching petechial rash in the context of fulminating sepsis and does not present subacutely as described here. Rheumatoid arthritis (RA) patients may have subcutaneous rheumatoid nodules on the extensor surfaces of the limbs, but RA does not give the findings described.

An abdominal ultrasound scan shows a cystic mass within the right lobe of the liver.
Which of the following represents the most effective treatment for this man?Your Answer:
Correct Answer: Drainage and albendazole po
Explanation:Treatment Options for Liver Cysts: Hydatid Disease and Amoebic Liver Abscess
Hydatid disease is a parasitic infection that can occur from consuming undercooked meat sold by street vendors. The majority of cysts occur in the liver, with the remaining cysts isolated to other areas of the body. The preferred treatment is drainage, either surgically or radiologically, along with the use of albendazole to reduce the risk of recurrence. Amoebic liver abscess is a potential differential diagnosis, but ultrasound findings can differentiate between the two. Metronidazole is used to manage amoebic liver cysts, while cefuroxime is used for pyogenic bacterial liver abscess. Definitive management for hydatid disease requires drainage of fluid. For amoebic liver abscess, metronidazole with or without drainage under ultrasound is the preferred treatment.

A 26-year-old woman presents with cyclical pelvic pain that worsens around her periods. The pain begins 3 days before the period and continues for several days after. She experiences dyspareunia and painful bowel movements. Previously, paracetamol and ibuprofen provided relief, but they are no longer effective.
During the examination, the patient exhibits generalised tenderness, a fixed and retroverted uterus, and uterosacral ligament nodules. Her BMI is 29 kg/m². She plans to start a family next year but is willing to take contraceptives if necessary.
What is the most appropriate next step in managing her condition?Your Answer:
Correct Answer: Offer combined oral contraceptive pill
Explanation:If analgesia is ineffective in treating endometriosis, the first-line option to try is the combined oral contraceptive pill or a progesterone.
The patient’s chronic cyclical pelvic pain, dyspareunia, secondary dysmenorrhoea, and pain with bowel movements are consistent with endometriosis. The examination findings also support this diagnosis. Paracetamol with or without an NSAID (such as mefenamic acid or ibuprofen) is the initial treatment for endometriosis. If these medications do not work, hormonal therapy (such as the combined oral contraceptive pill or medroxyprogesterone acetate) is the second-line option.
Since the patient plans to start a family within the next year, the combined oral contraceptive pill is the more appropriate choice as it does not delay fertility. Medroxyprogesterone acetate, also known as Depo Provera, provides contraception for up to 12 weeks but can delay fertility for up to 12 months and is irreversible once given. Additionally, the patient’s BMI of 34 kg/m² is a known risk factor for weight gain, which is a potential side effect of the injectable contraceptive.
Offering mefenamic acid is not recommended as analgesia has already been tried without success. If analgesia is ineffective in treating endometriosis, the combined oral contraceptive pill or a progesterone should be considered.
Referring the patient for consideration of GnRH analogue is not appropriate at this stage. This option is only considered if hormonal therapy is ineffective. It is important to trial the combined oral contraceptive pill before considering a referral.
Understanding Endometriosis
Endometriosis is a common condition where endometrial tissue grows outside of the uterus. It affects around 10% of women of reproductive age and can cause chronic pelvic pain, painful periods, painful intercourse, and subfertility. Other symptoms may include urinary problems and painful bowel movements. Diagnosis is typically made through laparoscopy, and treatment options depend on the severity of symptoms.
First-line treatments for symptomatic relief include NSAIDs and/or paracetamol. If these do not help, hormonal treatments such as the combined oral contraceptive pill or progestogens may be tried. If symptoms persist or fertility is a priority, referral to secondary care may be necessary. Secondary treatments may include GnRH analogues or surgery. For women trying to conceive, laparoscopic excision or ablation of endometriosis plus adhesiolysis is recommended, as well as ovarian cystectomy for endometriomas.
It is important to note that there is poor correlation between laparoscopic findings and severity of symptoms, and that there is little role for investigation in primary care. If symptoms are significant, referral for a definitive diagnosis is recommended.

A 72-year-old man experiences sudden paralysis on the right side of his body. He has been a smoker for 30 years, consuming 15 cigarettes a day. His vital signs are as follows: temperature 37.2°C, pulse 80/minute, respiratory rate 18/minute, and blood pressure 150/95 mm Hg. An angiogram of the brain shows blockage in a branch of the middle cerebral artery. Laboratory results indicate a haemoglobin A1c level of 80 mmol/mol (9.5%). Which component of blood lipids is the most significant factor in contributing to his condition?
Your Answer:
Correct Answer: Oxidised low-density lipoprotein (LDL)
Explanation:The patient had a stroke likely caused by cerebral atherosclerosis or embolic disease from the heart due to ischaemic heart disease from atherosclerosis. LDL brings cholesterol to arterial walls, and when there is increased LDL or hypertension, smoking, and diabetes, there is more degradation of LDL to oxidised LDL which is taken up into arterial walls via scavenger receptors in macrophages to help form atheromas. Chylomicrons transport exogenous products and are formed in intestinal epithelial cells. HDL particles remove cholesterol from the circulation and transport it back to the liver for excretion or re-utilisation. Lipoprotein lipase hydrolyses triglycerides in lipoproteins and promotes cellular uptake of chylomicron remnants, lipoproteins, and free fatty acids. VLDL transports endogenous triglycerides, phospholipids, and cholesterol and cholesteryl esters.

Linda is a 35-year-old woman who is 20 weeks pregnant. She presents to the emergency department with a 2 day history of sharp abdominal pain. There is no vaginal bleeding. She also has a low grade fever of 37.8 ºC. Her pregnancy until now has been unremarkable.
On examination, she is haemodynamically stable, but there is tenderness on palpation of the right lower quadrant of her abdomen. Fetal heart rate was normal. An ultrasound scan was performed which showed a singleton pregnancy, and multiple large fibroids in the uterus. The ovaries appeared normal and there was no appendix inflammation.
What is the most likely cause of Linda's symptoms?Your Answer:
Correct Answer: Fibroid degeneration
Explanation:During pregnancy, fibroid degeneration can occur and may cause symptoms such as low-grade fever, pain, and vomiting.
If the ultrasound scan does not show any signs of inflammation in the appendix, it is unlikely that the patient has appendicitis.
Since the patient has fibroids in her uterus, she is at risk of experiencing fibroid degeneration, which is a common complication during pregnancy. Symptoms of fibroid degeneration may include fever, pain, and vomiting.
The absence of vaginal bleeding makes it unlikely that the patient is experiencing a threatened miscarriage.
While ovarian torsion can cause pain and vomiting, it typically occurs in patients with risk factors such as ovarian cysts or ovarian enlargement.
Understanding Fibroid Degeneration
Uterine fibroids are non-cancerous growths that can develop in the uterus. They are sensitive to oestrogen and can grow during pregnancy. However, if the growth of the fibroids exceeds their blood supply, they can undergo a type of degeneration known as red or ‘carneous’ degeneration. This condition is characterized by symptoms such as low-grade fever, pain, and vomiting.
Fortunately, fibroid degeneration can be managed conservatively with rest and analgesia. With proper care, the symptoms should resolve within 4-7 days.

A 67-year-old man is admitted to the colorectal ward after undergoing resection of a large adenocarcinoma in his descending colon. The surgery involved a left hemicolectomy and removal of two loops of small bowel and a partial cystectomy due to tumour invasion. He is currently five days post-operation and is managing well with adequate pain control. However, his catheter has drained 2000ml in the last 24 hours, and his abdominal surgical drain is still producing 200-300 ml of clear yellow fluid per day. There is a concern that his bladder wall repair may be leaking urine. What investigation should be ordered to provide the most definitive result in assessing the healing of the bladder suture line?
Your Answer:
Correct Answer: Cystogram
Explanation:To perform a cystogram, a radiopaque dye is injected into the bladder and radiographs are taken to examine the movement of the bladder contents. This helps to determine if there is any radiopaque fluid that has leaked from the bladder and is now present in the abdominal cavity.
Functional renal imaging techniques are used to assess the structure and function of the kidneys. One such technique is dimercaptosuccinic acid (DMSA) scintigraphy, which localizes to the renal cortex and is useful for identifying cortical defects and ectopic or abhorrent kidneys. However, it does not provide information on the ureter or collecting system. Diethylene-triamine-penta-acetic acid (DTPA) is primarily a glomerular filtration agent and provides information on the glomerular filtration rate (GFR). MAG 3 renogram is an agent that is primarily secreted by tubular cells and is useful for imaging the kidneys of patients with existing renal impairment. Micturating cystourethrogram (MCUG scan) provides information on bladder reflux, while intravenous urography may provide evidence of renal stones or other structural lesions. PET/CT may be used to evaluate structurally indeterminate lesions in the staging of malignancy.

A 28-year-old pregnant woman with type 1 diabetes inquires about the frequency of blood glucose level testing during her pregnancy.
Your Answer:
Correct Answer: Daily fasting, pre-meal, 1-hour post-meal and bedtime tests.
Explanation:It is important for pregnant individuals with type 1 diabetes to closely monitor their blood glucose levels by testing multiple times throughout the day. This is recommended by NICE NG3.
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.

A 55-year-old male with a history of alcoholism complains of intense epigastric pain that extends to his back. During the physical examination, the epigastrium is sensitive to touch, and there are signs of bruising on the flanks. What would be a sign of a severe illness based on the probable diagnosis?
Your Answer:
Correct Answer: Calcium of 1.98 mmol/L
Explanation:Hypocalcaemia is a sign of severe pancreatitis according to the Glasgow score, while hypercalcaemia can actually cause pancreatitis. This patient’s symptoms and history suggest acute pancreatitis, with the Glasgow score indicating potential severity. The mnemonic PANCREAS can be used to remember the criteria for severe pancreatitis, with a score of 3 or higher indicating high risk.
Understanding Acute Pancreatitis
Acute pancreatitis is a condition that is commonly caused by alcohol or gallstones. It occurs when the pancreatic enzymes start to digest the pancreatic tissue, leading to necrosis. The main symptom of acute pancreatitis is severe epigastric pain that may radiate through to the back. Vomiting is also common, and examination may reveal epigastric tenderness, ileus, and low-grade fever. In rare cases, periumbilical discolouration (Cullen’s sign) and flank discolouration (Grey-Turner’s sign) may be present.
To diagnose acute pancreatitis, doctors typically measure the levels of serum amylase and lipase in the blood. While amylase is raised in 75% of patients, it does not correlate with disease severity. Lipase, on the other hand, is more sensitive and specific than amylase and has a longer half-life. Imaging tests, such as ultrasound and contrast-enhanced CT, may also be used to assess the aetiology of the condition.
Scoring systems, such as the Ranson score, Glasgow score, and APACHE II, are used to identify cases of severe pancreatitis that may require intensive care management. Factors that indicate severe pancreatitis include age over 55 years, hypocalcaemia, hyperglycaemia, hypoxia, neutrophilia, and elevated LDH and AST. It is important to note that the actual amylase level is not of prognostic value.
In summary, acute pancreatitis is a condition that can cause severe pain and discomfort. It is typically caused by alcohol or gallstones and can be diagnosed through blood tests and imaging. Scoring systems are used to identify cases of severe pancreatitis that require intensive care management.

You are a FY-1 doctor working in obstetrics. For one day a week you are based in the early pregnancy assessment unit (EPAU). You are assessing a 28-year-old female with a suspected threatened miscarriage. How does this condition typically manifest?
Your Answer:
Correct Answer: Painless per-vaginal bleeding and a closed cervical os
Explanation:A threatened miscarriage is characterized by bleeding, but the cervical os remains closed. Miscarriages can be classified as threatened, inevitable, incomplete, complete, or missed. Mild bleeding and little to no pain are typical symptoms of a threatened miscarriage. In contrast, an inevitable miscarriage is marked by heavy bleeding with clots and pain, and the cervical os is open. Inevitable miscarriages will not result in a continued pregnancy and will progress to incomplete or complete miscarriages.
Miscarriage is a common complication that can occur in up to 25% of all pregnancies. There are different types of miscarriage, each with its own set of symptoms and characteristics. Threatened miscarriage is painless vaginal bleeding that occurs before 24 weeks, typically at 6-9 weeks. The bleeding is usually less than menstruation, and the cervical os is closed. Missed or delayed miscarriage is when a gestational sac containing a dead fetus is present before 20 weeks, without the symptoms of expulsion. The mother may experience light vaginal bleeding or discharge, and the symptoms of pregnancy may disappear. Pain is not usually a feature, and the cervical os is closed. Inevitable miscarriage is characterized by heavy bleeding with clots and pain, and the cervical os is open. Incomplete miscarriage occurs when not all products of conception have been expelled, and there is pain and vaginal bleeding. The cervical os is open in this type of miscarriage.

On examination, he appears dishevelled and drowsy, with a pulse of 116 bpm and a blood pressure of 110/60 mmHg.
His blood tests reveal a pH of 7.29 (7.36-7.44), PaO2 of 12.0 kPa (11.3-12.6), PaCO2 of 3.0 kPa (4.7-6.0), standard bicarbonate of 18 mmol/L (20-28), base excess of −9 mmol/L (+/−2), lactate of 1.6 mmol/L (0.5-2.2), blood glucose of 3.9 mmol/L (3.0-6.0), and urine dipstick Ketones+++.
What is the probable diagnosis?Your Answer:
Correct Answer: Starvation ketosis
Explanation:Metabolic Acidosis in a Starving Patient
This patient is experiencing metabolic acidosis due to starvation, which is evident from the positive ketones found in his urine dipstick. His medical history suggests that he may be an alcoholic and homeless. As a result of his starvation, his body has switched to ketone metabolism. However, he is not diabetic, and his lactate levels are normal.
To treat this condition, the patient needs to receive IV dextrose to reverse the ketosis and correct his acidosis. However, it is important to note that the patient must receive thiamine first to prevent the onset of Wernicke’s encephalopathy, which can be triggered by IV glucose.
Overall, this patient’s condition highlights the importance of proper nutrition and medical care, particularly for those who may be homeless or struggling with addiction. By addressing his metabolic acidosis and providing him with the necessary treatment, healthcare providers can help improve his overall health and well-being.

A 32-year-old woman presents to the Emergency Department at midnight with sudden and severe lower abdominal pain. The pain is sharp and constant, with a rating of 10/10, and is spreading to her lower back. She is unable to lie still due to the pain. She is experiencing nausea but has not vomited. Her last menstrual period was two weeks ago and was normal, and her menstrual cycle is always regular.
During the examination, her blood pressure is 110/70 mmHg, pulse rate is 110 bpm, respiratory rate is 18 breaths/min, and temperature is 37.3 °C. There is tenderness in the periumbilical and right lower quadrant upon palpation. Abdominal ultrasound reveals a significant amount of free pelvic fluid.
What is the most likely organ or structure that is injured in this patient?Your Answer:
Correct Answer: Ovary
Explanation:Possible Causes of Sudden Pelvic Pain: A Differential Diagnosis
Sudden pelvic pain can be a sign of various medical conditions. In this case, the patient’s symptoms suggest ovarian torsion, a condition that occurs when the ovary twists on its blood supply, causing ischemia and infarction. The resulting pain is severe, sharp, and sudden, often accompanied by tenderness and internal bleeding. However, other possible causes of sudden pelvic pain should also be considered.
Rectal diseases or trauma are unlikely to explain the patient’s current presentation. Similarly, while appendicitis can cause abdominal pain, fever, nausea, and anorexia, the pattern of pain is different, starting as dull pain around the belly button and becoming sharp and localized to the right lower quadrant over time. Rovsing’s sign, which is pain in the right lower quadrant when pressure is applied to the left lower quadrant, is often positive in appendicitis.
A ureteral stone can also cause sudden-onset pelvic and flank pain, but it is not associated with pelvic bleeding. Urinary tract stones typically cause colicky pain, which comes and goes in waves, rather than the unrelenting pain described by the patient.
Finally, a ruptured Fallopian tube can be a complication of an ectopic pregnancy, but the patient’s recent normal menstrual periods make this diagnosis less likely. In ectopic tubal pregnancy, the patient usually complains of amenorrhea, abnormal uterine bleeding, and pelvic pain of several days to weeks’ duration.
In summary, while ovarian torsion is a possible cause of the patient’s sudden pelvic pain, other conditions should also be considered and ruled out through further evaluation and testing.

Which nerve provides the motor supply to the brachialis muscle?
Your Answer:
Correct Answer: Radial and musculocutaneous nerve
Explanation:The Brachialis Muscle: Anatomy and Innervation
The brachialis muscle is responsible for flexing the forearm and is located in the anterior half of the humerus and intermuscular septa. It attaches to the coronoid process and tuberosity of the ulna at the elbow joint. The main nerve supply for the brachialis muscle is the musculocutaneous nerve, with C6 and radial nerve also playing a role. Additionally, the lateral part of the brachialis muscle is supplied by branches from the C7 root. Overall, the brachialis muscle is an important muscle for forearm flexion and is innervated by multiple nerves.

The patient has been following a strict vegan diet for the past six years and has a history of Crohn's disease. He is currently receiving immunomodulation therapy for his condition. His vital signs are within normal limits.
Upon examination of his mouth, a beefy-red tongue is observed. His neurological exam is unremarkable.
What is the most suitable course of treatment for this patient?Your Answer:
Correct Answer: Vitamin B12 supplementation
Explanation:Supplementation Options for Nutrient Deficiencies: A Clinical Overview
Vitamin B12 Supplementation for Deficiency
Vitamin B12 is a crucial nutrient involved in the production of red blood cells. Its deficiency can cause various clinical presentations, including glossitis, jaundice, depression, psychosis, and neurological findings like subacute combined degeneration of the spinal cord. The deficiency is commonly seen in strict vegans and patients with diseases affecting the terminal ileum. Management depends on the cause, and oral supplementation is recommended for dietary causes, while intramuscular injections are indicated for malabsorption.
Folate Supplementation for Deficiency
Folate deficiency is typically seen in patients with alcoholism and those taking anti-folate medications. However, the clinical findings of folate deficiency are different from those of vitamin B12 deficiency. Patients with folate deficiency may present with fatigue, weakness, and pallor.
Magnesium Supplementation for Hypomagnesaemia
Hypomagnesaemia is commonly seen in patients with severe diarrhoea, diuretic use, alcoholism, or long-term proton pump inhibitor use. The clinical presentation of hypomagnesaemia is variable but classically involves ataxia, paraesthesia, seizures, and tetany. Management involves magnesium replacement.
Oral Steroids for Acute Exacerbations of Crohn’s Disease
Oral steroids are indicated in patients suffering from acute exacerbations of Crohn’s disease, which typically presents with abdominal pain, diarrhoea, fatigue, and fevers.
Vitamin D Supplementation for Deficiency
Vitamin D deficiency is typically seen in patients with dark skin, fatigue, bone pain, weakness, and osteoporosis. Supplementation is recommended for patients with vitamin D deficiency.

A 35-year-old woman is 39 weeks pregnant with twins (dichorionic diamniotic). During labor, the midwife observes the umbilical cord protruding from the vagina. The emergency button is pressed, and the woman is rushed for an emergency C-section. What is the most probable cause of umbilical cord prolapse?
Your Answer:
Correct Answer: Artificial amniotomy
Explanation:The most probable reason for umbilical cord prolapse is artificial rupture of membranes. Factors such as cephalic presentation, nulliparity, and prolonged pregnancy decrease the chances of cord prolapse. Prostaglandins do not significantly affect the risk of cord prolapse.
Understanding Umbilical Cord Prolapse
Umbilical cord prolapse is a rare but serious complication that can occur during delivery. It happens when the umbilical cord descends ahead of the presenting part of the fetus, which can lead to compression or spasm of the cord. This can cause fetal hypoxia and potentially irreversible damage or death. Certain factors increase the risk of cord prolapse, such as prematurity, multiparity, polyhydramnios, twin pregnancy, cephalopelvic disproportion, and abnormal presentations like breech or transverse lie.
Around half of all cord prolapses occur when the membranes are artificially ruptured. Diagnosis is usually made when the fetal heart rate becomes abnormal and the cord is palpable vaginally or visible beyond the introitus. Cord prolapse is an obstetric emergency that requires immediate management. The presenting part of the fetus may be pushed back into the uterus to avoid compression, and the cord should be kept warm and moist to prevent vasospasm. The patient may be asked to go on all fours or assume the left lateral position until preparations for an immediate caesarian section have been carried out. Tocolytics may be used to reduce uterine contractions, and retrofilling the bladder with saline can help elevate the presenting part. Although caesarian section is the usual first-line method of delivery, an instrumental vaginal delivery may be possible if the cervix is fully dilated and the head is low.
In conclusion, umbilical cord prolapse is a rare but serious complication that requires prompt recognition and management. Understanding the risk factors and appropriate interventions can help reduce the incidence of fetal mortality associated with this condition.

What is the most frequent complication associated with a clavicle fracture?
Your Answer:
Correct Answer: Malunion
Explanation:Complications and Risk Factors in Clavicle Fractures
Clavicle fractures are common injuries that can result in various complications. The most frequent complication is malunion, which can cause angulation, shortening, and poor appearance. Although non-anatomic union is typical of most displaced middle-third clavicle fractures, many experts suggest that such malunion does not significantly affect function.
Nonunion is another complication that occurs when there is a failure to show clinical or radiographic progression of healing after four to six months. Several risk factors have been identified, including the extent of initial trauma, fracture combinations, fracture displacement, inadequate immobilisation, distal-third fractures, primary open reduction, and refracture.
It is essential to identify these risk factors to prevent complications and ensure proper treatment. Adequate immobilisation and careful monitoring of the healing process are crucial in preventing nonunion and malunion. In cases where complications do occur, prompt intervention can help minimise the impact on function and appearance.

A 29-year-old pregnant woman presents at 40 weeks gestation for an artificial rupture of the membranes. Following the procedure, a vaginal examination reveals a palpable umbilical cord. What position should she be advised to assume?
Your Answer:
Correct Answer: On all fours, on the knees and elbows
Explanation:When a woman experiences cord prolapse, the correct position for her is on all fours, with her knees and elbows on the ground. This condition can be caused by artificial rupture of the membranes, and it is important to keep the cord warm and moist while preparing for a caesarian section. The Trendelenburg position, which involves tilting the head-end of the bed downwards, is used in abdominal surgery to shift abdominal contents upwards. The Lloyd Davis position, which involves separating the legs and tilting the head-end of the bed downwards, is used in rectal and pelvic surgery. The McRoberts manoeuvre, which involves hyperflexing the legs tightly to the abdomen, is used in cases of shoulder dystocia during delivery, but not for cord prolapse. The lithotomy position, which involves raising the legs in stirrups and separating them, is used in obstetrics and gynaecology for various procedures, but not for cord prolapse.

Question 21
Incorrect

The following arterial blood gases (ABGs) were taken from an unconscious 50-year-old woman in the Emergency department on FiO2 of 21%:
pH 7.36 (7.36-7.44)
pO2 13.0 kPa (11.3-12.6)
pCO2 3.7 kPa (4.7-6.0)
HCO3− 15 mmol/L (20-28)
What is the correct interpretation of the ABG result?Your Answer:
Correct Answer: Compensated metabolic acidosis
Explanation:Interpretation of ABG Results
The pH and bicarbonate levels in the ABG results indicate the presence of acidosis. However, the low level of carbon dioxide suggests that it is more likely to be metabolic acidosis rather than respiratory acidosis. The body tries to compensate for the acidosis by increasing the respiratory rate, which helps to eliminate excess hydrogen ions as carbon dioxide. This compensation can also lead to high oxygen levels due to deep and rapid breathing. However, it is important to note that high oxygen levels may also be a result of oxygen therapy provided in the Emergency department. It is worth mentioning that delayed analysis of ABG samples can sometimes lead to inaccurate results, such as a falsely low pO2. However, there is no indication that this has occurred in this particular case.

A 32-year-old pregnant woman is concerned about the risk of measles, mumps, and rubella (MMR) infection for her unborn baby. She has never been vaccinated for MMR and is currently 14 weeks pregnant. There are no sick contacts around her.
What is the appropriate course of action in this situation?Your Answer:
Correct Answer: Refrain from giving her any MMR vaccination now and at any stage of her pregnancy
Explanation:The MMR vaccine, which contains live attenuated virus, should not be given to women who are pregnant or trying to conceive. It is recommended that women avoid getting pregnant for at least 28 days after receiving the vaccine. If a pregnant woman is not immune to MMR, she should avoid contact with individuals who have the disease. In the event that a woman receives the MMR vaccine unintentionally during the periconception period or early pregnancy, termination of pregnancy is not necessary. This information is based on the guidelines provided by the American College of Obstetricians and Gynecologists.
Rubella and Pregnancy: Risks, Features, Diagnosis, and Management
Rubella, also known as German measles, is a viral infection caused by the togavirus. Thanks to the introduction of the MMR vaccine, it is now rare. However, if contracted during pregnancy, there is a risk of congenital rubella syndrome, which can cause serious harm to the fetus. It is important to note that the incubation period is 14-21 days, and individuals are infectious from 7 days before symptoms appear to 4 days after the onset of the rash.
The risk of damage to the fetus is highest in the first 8-10 weeks of pregnancy, with a risk as high as 90%. However, damage is rare after 16 weeks. Features of congenital rubella syndrome include sensorineural deafness, congenital cataracts, congenital heart disease (e.g. patent ductus arteriosus), growth retardation, hepatosplenomegaly, purpuric skin lesions, ‘salt and pepper’ chorioretinitis, microphthalmia, and cerebral palsy.
If a suspected case of rubella in pregnancy arises, it should be discussed immediately with the local Health Protection Unit (HPU) as type/timing of investigations may vary. IgM antibodies are raised in women recently exposed to the virus. It should be noted that it is very difficult to distinguish rubella from parvovirus B19 clinically. Therefore, it is important to also check parvovirus B19 serology as there is a 30% risk of transplacental infection, with a 5-10% risk of fetal loss.
If a woman is tested at any point and no immunity is demonstrated, they should be advised to keep away from people who might have rubella. Non-immune mothers should be offered the MMR vaccination in the post-natal period. However, MMR vaccines should not be administered to women known to be pregnant or attempting to become pregnant.

A 40-year-old man in a heterosexual relationship is seeking advice on contraception options after undergoing a vasectomy. What recommendations can be provided to him?
Your Answer:
Correct Answer: Use additional contraception until semen analysis reveals azoospermia
Explanation:It is important to inform the patient that vasectomy is not an immediate form of contraception. A semen analysis must be performed twice after the procedure to confirm azoospermia before it can be used as contraception. Therefore, the most appropriate advice would be to use additional contraception until the semen analysis confirms azoospermia. While abstinence is a safe option, it may not be practical for the patient’s sexual life. Advising that there is no need for additional contraception or suggesting that the patient’s partner use hormonal contraception is incorrect. It is important to give advice directly to the patient. Additionally, there is no defined timeframe for when vasectomy becomes effective. The patient will need to produce a sample for analysis about 12 weeks after the procedure, and only when tests confirm azoospermia can the patient stop using additional contraception. This typically occurs around 16 to 20 weeks after the procedure.
Vasectomy: A Simple and Effective Male Sterilisation Method
Vasectomy is a male sterilisation method that has a failure rate of 1 per 2,000, making it more effective than female sterilisation. The procedure is simple and can be done under local anesthesia, with some cases requiring general anesthesia. After the procedure, patients can go home after a couple of hours. However, it is important to note that vasectomy does not work immediately.
To ensure the success of the procedure, semen analysis needs to be performed twice following a vasectomy before a man can have unprotected sex. This is usually done at 12 weeks after the procedure. While vasectomy is generally safe, there are some complications that may arise, such as bruising, hematoma, infection, sperm granuloma, and chronic testicular pain. This pain affects between 5-30% of men.
In the event that a man wishes to reverse the procedure, the success rate of vasectomy reversal is up to 55% if done within 10 years. However, the success rate drops to approximately 25% after more than 10 years. Overall, vasectomy is a simple and effective method of male sterilisation, but it is important to consider the potential complications and the need for semen analysis before engaging in unprotected sex.

A 35-year-old female presents to the emergency department with persistent right upper quadrant pain and jaundiced sclera, three weeks after undergoing laparoscopic cholecystectomy. She is anxious about the possibility of a surgical complication requiring revision surgery.
What is the probable cause of her symptoms?Your Answer:
Correct Answer: Gallstones present in the common bile duct causing symptoms
Explanation:The correct answer to the multiple-choice question is CBD gallstones. While gallbladder stump gallstones can occur after laparoscopic cholecystectomies, they are less common than CBD gallstones. Additionally, it is important to note that the patient in the vignette is presenting 3 weeks after the operation, whereas gallbladder stump gallstones typically present over 9 months following incomplete gallbladder removal (although in rare cases, it can take up to 25 years postoperatively).
Biliary colic is a condition that occurs when gallstones pass through the biliary tree. The risk factors for this condition are commonly referred to as the ‘4 F’s’, which include being overweight, female, fertile, and over the age of forty. Other risk factors include diabetes, Crohn’s disease, rapid weight loss, and certain medications. Biliary colic occurs due to an increase in cholesterol, a decrease in bile salts, and biliary stasis. The pain associated with this condition is caused by the gallbladder contracting against a stone lodged in the cystic duct. Symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Diagnosis is typically made through ultrasound. Elective laparoscopic cholecystectomy is the recommended treatment for biliary colic. However, around 15% of patients may have gallstones in the common bile duct at the time of surgery, which can result in obstructive jaundice. Other possible complications of gallstone-related disease include acute cholecystitis, ascending cholangitis, acute pancreatitis, gallstone ileus, and gallbladder cancer.

A 28-year-old male arrived at the emergency department with a humeral shaft fracture after falling from a rooftop during a party. He admits to taking recreational drugs before the incident but is unsure of what he consumed. After receiving analgesia, he undergoes surgery to fix his fracture with a coaptation splint and functional brace. The next day, he reports suprapubic pain and difficulty urinating, leading to a diagnosis of acute urinary retention. What drug is the probable cause of his urinary retention?
Your Answer:
Correct Answer: Morphine sulfate
Explanation:Urinary retention is a common side effect of opioid analgesia, with morphine sulfate being a frequent culprit. While cannabis contains THC, which produces a psychoactive effect, it is not typically associated with acute urinary retention. Cocaine overdose can cause cardiovascular and sympathetic effects, but not an increased risk of urinary retention. Ketamine use may lead to ketamine bladder syndrome, which causes urinary frequency and urgency rather than retention.
Drugs that can cause urinary retention
Urinary retention is a condition where a person is unable to empty their bladder completely. This can be caused by various factors, including certain medications. Some drugs that may lead to urinary retention include tricyclic antidepressants like amitriptyline, anticholinergics such as antipsychotics and antihistamines, opioids, NSAIDs, and disopyramide. These drugs can affect the muscles that control the bladder, making it difficult to urinate.

What is the most suitable time to collect blood samples for therapeutic monitoring of lithium levels?
Your Answer:
Correct Answer: 12 hours after last dose
Explanation:Therapeutic Drug Monitoring: Guidelines for Monitoring Lithium, Ciclosporin, Digoxin, and Phenytoin Levels
Lithium levels should be monitored 12 hours after the last dose, with the target range being 0.4-1.0 mmol/l. Ciclosporin levels should be measured immediately before the next dose, while Digoxin levels should be checked at least 6 hours after the last dose. Phenytoin levels do not need to be monitored routinely, but trough levels should be checked before the next dose if there is a need to adjust the dose, suspected toxicity, or non-adherence to the prescribed medication.
Therapeutic drug monitoring is an essential aspect of patient care, especially for drugs with narrow therapeutic windows. The guidelines for monitoring lithium, ciclosporin, digoxin, and phenytoin levels vary depending on the drug and the patient’s condition. It is crucial to follow these guidelines to ensure that the patient receives the optimal dose of medication and to prevent adverse effects. Proper monitoring of drug levels can also help detect non-adherence to the prescribed medication, which can affect treatment outcomes. By following these guidelines, healthcare professionals can provide safe and effective treatment to their patients.

A 50-year-old woman comes to see her GP complaining of persistent abdominal cramping, bloating, and diarrhoea that has been going on for 5 months. She reports no blood in her stools, no unexplained weight loss, and no fatigue. Her medical history includes obesity, but there is no family history of any relevant conditions.
Upon examination, her heart rate is 80 bpm, her blood pressure is 130/75 mmHg, and she has no fever. Both her abdominal and pelvic exams are unremarkable, and there is no pallor or jaundice.
What is the most appropriate next step in managing this patient's symptoms?Your Answer:
Correct Answer: Measure serum CA-125
Explanation:If a woman aged 50 or older presents with persistent symptoms of irritable bowel syndrome (IBS), such as cramping, bloating, and diarrhoea, ovarian cancer should be suspected even without other symptoms like unexplained weight loss or fatigue. This is because ovarian cancer often presents with non-specific symptoms similar to IBS and rarely occurs for the first time in patients aged 50 or older. It is important to measure serum CA-125 to help diagnose ovarian cancer. An abdominal and pelvic examination should also be carried out, but if this is normal, measuring CA-125 is the next step. Ultrasound scans of the abdomen and pelvis are recommended once CA-125 has been measured, and if these suggest malignancy, other ultrasounds may be considered under specialist guidance. Measuring anti-TTG antibodies is not necessary in this case, as IBS rarely presents for the first time in patients aged 50 or older. Urgent referral to gastroenterology is not appropriate unless the patient has features of inflammatory bowel disease.
Ovarian cancer is a common malignancy in women, ranking fifth in frequency. It is most commonly diagnosed in women over the age of 60 and has a poor prognosis due to late detection. The majority of ovarian cancers, around 90%, are of epithelial origin, with serous carcinomas accounting for 70-80% of cases. Interestingly, recent research suggests that many ovarian cancers may actually originate in the distal end of the fallopian tube. Risk factors for ovarian cancer include a family history of BRCA1 or BRCA2 gene mutations, early menarche, late menopause, and nulliparity.
Clinical features of ovarian cancer are often vague and can include abdominal distension and bloating, abdominal and pelvic pain, urinary symptoms such as urgency, early satiety, and diarrhea. The initial diagnostic test recommended by NICE is a CA125 blood test, although this can also be elevated in other conditions such as endometriosis and benign ovarian cysts. If the CA125 level is raised, an urgent ultrasound scan of the abdomen and pelvis should be ordered. However, a CA125 test should not be used for screening asymptomatic women. Diagnosis of ovarian cancer is difficult and usually requires a diagnostic laparotomy.
Management of ovarian cancer typically involves a combination of surgery and platinum-based chemotherapy. Unfortunately, 80% of women have advanced disease at the time of diagnosis, leading to a 5-year survival rate of only 46%. It was previously thought that infertility treatment increased the risk of ovarian cancer due to increased ovulation, but recent evidence suggests that this is not a significant factor. In fact, the combined oral contraceptive pill and multiple pregnancies have been shown to reduce the risk of ovarian cancer by reducing the number of ovulations.

A 66-year-old smoker visits his GP complaining of a persistent cough, difficulty breathing, weight loss (5 kg), and night sweats that have been going on for 8 months. An urgent chest X-ray is ordered, which reveals multiple well-defined central opacities. A blood test shows the following abnormality:
calcium: 3.7 mmol/l (2.1–2.6 mmol/l).
What type of lung cancer is the most probable diagnosis based on these findings?Your Answer:
Correct Answer: Squamous cell
Explanation:Differentiating Lung Cancer Types Based on CXR Findings and Hypercalcemia
When examining a patient with lung cancer and hypercalcemia, the CXR findings can help narrow down the potential types of cancer. Central opacities make adenocarcinoma and bronchoalveolar cancer less likely, as they typically present in the peripheral lung fields and with extensive widespread opacities, respectively. Squamous cell carcinoma is a possible culprit, as it is known to produce parathyroid hormone-related protein (PTHrP), which can cause hypercalcemia. Small-cell cancer is known for producing ADH and ACTH, not PTHrP. Large-cell cancer is unlikely to produce PTHrP, and adenocarcinoma usually presents peripherally and is unlikely to produce PTHrP. Therefore, considering CXR findings and hypercalcemia can aid in differentiating between lung cancer types.

A 30-year-old asymptomatic woman comes to the hospital for an oral glucose tolerance test (OGTT). She is currently 16 weeks pregnant with her second child. During her first pregnancy, she had gestational diabetes and foetal macrosomia. Despite having a body mass index of 34 kg/m2, she is in good health.
Her test results are as follows:
- Fasting glucose: 8.5 mmol/L (<5.6 mmol/L)
- 2 hour glucose: 12.8 mmol/L (<7.8 mmol/L)
What is the recommended course of action for managing her condition?Your Answer:
Correct Answer: Insulin plus or minus metformin
Explanation:If a woman is diagnosed with gestational diabetes and her fasting glucose level is equal to or greater than 7 mmol/l, immediate treatment with insulin (with or without metformin) should be initiated. For women with a fasting glucose level below 7 mmol/l at diagnosis, lifestyle modifications such as diet and exercise should be recommended. If blood glucose targets are not achieved within 1-2 weeks using lifestyle modifications, metformin may be prescribed. Glibenclamide can be considered for women who do not reach their blood glucose targets with metformin or who refuse insulin therapy. Pioglitazone should be avoided during pregnancy as animal studies have shown it to be harmful.
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.

A 32-year-old woman presents to her GP with complaints of feeling extremely anxious, avoiding going out, and experiencing disturbed sleep. Her symptoms have resulted in the breakdown of her relationship. She reports that her symptoms began to worsen after she was sexually assaulted 2 years ago. She experiences flashbacks of the assault when she is in a confined space with someone, even if there is no physical contact. The GP decides to refer her for cognitive behavioural therapy and the patient also expresses interest in trying medication. Which of the following medications would be recommended for the management of this patient?
Your Answer:
Correct Answer: Venlafaxine
Explanation:Medications for Post-Traumatic Stress Disorder (PTSD)
Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing a traumatic event. Symptoms of PTSD include flashbacks, nightmares, avoidance, and hyperarousal. If drug treatment is necessary, selective serotonin reuptake inhibitors (SSRIs) or venlafaxine are recommended. Tricyclic antidepressants and benzodiazepines are not recommended due to their potential risks and lack of efficacy in treating PTSD. Antipsychotics may be considered in patients who do not respond to other treatments. It is important to regularly review and adjust medication treatment for PTSD.
