    Correct

    • You are a male FY1 working in obstetrics. A 35-year-old female is on the ward in labour, 10 minutes ago she suffered a placental abruption and is in need of emergency care. Her midwife comes to see you, informing you that she is requesting to only be seen and cared for by female doctors. How do you respond?

      Your Answer: Ask the midwife to immediately summon senior medical support, regardless of gender

      Explanation:

      Placental abruption is a critical obstetric emergency that requires immediate attention to prevent severe blood loss and potential harm to both the mother and baby. While patients have the right to choose their doctor, this right does not apply in emergency situations where prompt treatment is necessary to save the patient’s life. Therefore, suggesting that the patient wait for a female doctor or return in an hour is inappropriate and could result in a dangerous delay in medical care. It is also unnecessary to label the comment as sexist and document it in the patient’s notes. While it is important to respect the patient’s preferences, the priority in this situation is to provide urgent medical attention. Similarly, asking a midwife to take on the role of a doctor is not a safe or appropriate solution, as their training and responsibilities differ. Ultimately, if a female doctor is not available, the patient must be treated by a male doctor to address the emergency as quickly and effectively as possible.

      Placental Abruption: Causes, Symptoms, and Risk Factors

      Placental abruption is a condition that occurs when the placenta separates from the uterine wall, leading to maternal bleeding into the space between them. Although the exact cause of this condition is unknown, certain factors have been associated with it, including proteinuric hypertension, cocaine use, multiparity, maternal trauma, and increasing maternal age. Placental abruption is not a common occurrence, affecting approximately 1 in 200 pregnancies.

      The clinical features of placental abruption include shock that is disproportionate to the visible blood loss, constant pain, a tender and tense uterus, and a normal lie and presentation of the fetus. The fetal heart may be absent or distressed, and there may be coagulation problems. It is important to be aware of other conditions that may present with similar symptoms, such as pre-eclampsia, disseminated intravascular coagulation (DIC), and anuria.

      In summary, placental abruption is a serious condition that can have significant consequences for both the mother and the fetus. Understanding the risk factors and symptoms of this condition is important for early detection and appropriate management.

    Correct

    • A 16-year-old previously healthy woman presents with a 10-month history of persistent non-bloody diarrhoea and central abdominal pain. She also gives a history of unintentional weight loss. The patient is not yet menstruating. On examination, she has slight conjunctival pallor. Blood tests reveal a macrocytic anaemia.
      What is the likeliest diagnosis?

      Your Answer: Coeliac disease

      Explanation:

      Coeliac disease is a condition where the lining of the small intestine is abnormal and improves when gluten is removed from the diet. It is caused by an immune response to a component of gluten called α-gliadin peptide. Symptoms can occur at any age but are most common in infancy and in adults in their 40s. Symptoms include abdominal pain, bloating, diarrhea, delayed puberty, and anemia. Blood tests are used to diagnose the disease, and a biopsy of the small intestine can confirm the diagnosis. Treatment involves avoiding gluten in the diet. Crohn’s disease and ulcerative colitis have different symptoms, while irritable bowel syndrome and carcinoid syndrome are unlikely in this case.

    Incorrect

    • A 68-year-old on the post-surgical ward has been experiencing persistent vomiting since their abdominal surgery for colorectal cancer 4 days ago. After a surgical evaluation, it has been determined that the patient does not require any additional surgery. The medical team is worried about the patient's deteriorating nutritional status and decides that the patient needs to be treated for malnutrition. What is the most suitable treatment option?

      Your Answer: Total parenteral nutrition via a cannula already placed in the patient's hand

      Correct Answer: Total parenteral nutrition via a peripherally inserted central catheter

      Explanation:

      Total parenteral nutrition is the appropriate treatment for this patient with intractable vomiting and severe malnutrition. However, it should be administered via a central vein to avoid phlebitis. A peripherally inserted central catheter is the recommended method for delivering parenteral nutrition. Increasing oral intake and oral nutritional supplements are not suitable options for this patient due to their persistent vomiting. While a percutaneous endoscopic tube may be necessary for long-term feeding, it is not the best option at this stage as it is invasive and the patient’s condition may be reversible.

      Nutrition Options for Surgical Patients

      When it comes to providing nutrition for surgical patients, there are several options available. The easiest and most common option is oral intake, which can be supplemented with calorie-rich dietary supplements. However, this may not be suitable for all patients, especially those who have undergone certain procedures.

      nasogastric feeding is another option, which involves administering feed through a fine bore nasogastric feeding tube. While this method may be safe for patients with impaired swallow, there is a risk of aspiration or misplaced tube. It is also usually contra-indicated following head injury due to the risks associated with tube insertion.

      Naso jejunal feeding is a safer alternative as it avoids the risk of feed pooling in the stomach and aspiration. However, the insertion of the feeding tube is more technically complicated and is easiest if done intra-operatively. This method is safe to use following oesophagogastric surgery.

      Feeding jejunostomy is a surgically sited feeding tube that may be used for long-term feeding. It has a low risk of aspiration and is thus safe for long-term feeding following upper GI surgery. However, there is a risk of tube displacement and peritubal leakage immediately following insertion, which carries a risk of peritonitis.

      Percutaneous endoscopic gastrostomy is a combined endoscopic and percutaneous tube insertion method. However, it may not be technically possible in patients who cannot undergo successful endoscopy. Risks associated with this method include aspiration and leakage at the insertion site.

      Finally, total parenteral nutrition is the definitive option for patients in whom enteral feeding is contra-indicated. However, individualised prescribing and monitoring are needed, and it should be administered via a central vein as it is strongly phlebitic. Long-term use is associated with fatty liver and deranged LFTs.

      In summary, there are several nutrition options available for surgical patients, each with its own benefits and risks. The choice of method will depend on the patient’s individual needs and circumstances.

    Incorrect

    • A 70-year-old woman is being discharged from the Surgical Ward following a midline laparotomy for a perforated duodenal ulcer. She has several surgical staples in situ.
      How many days post-surgery should the staples be removed?

      Your Answer: 14–21 days

      Correct Answer: 10–14 days

      Explanation:

      Proper Timing for Suture Removal

      The length of time sutures should remain in place varies depending on the location of the wound and the tension across it. Sutures on the chest, stomach, or back should be removed after 10-14 days to prevent wound dehiscence while reducing the risk of infection and scarring. Facial sutures can be removed after 5-7 days, while sutures over the lower extremities or joints typically need removing after 14-21 days. Sutures should not be left in place for more than 21 days due to the increased likelihood of infection, scarring, and difficult removal. It is important to keep wounds dry for the first 24 hours and avoid baths and swimming until sutures are removed.

    • You are assessing an 85-year-old woman with advanced dementia who is bed-bound and has a grade two pressure ulcer. Her carer thinks she feels pain when being moved in bed. The patient takes no pain medication at present. The patient is having severe nausea, vomiting and has severely impaired mental status.
      Which of the following is the most appropriate prescription?

      Your Answer: Paracetamol 1 g intravenous

      Correct Answer: Paracetamol 1 g per rectum

      Explanation:

      Choosing Appropriate Pain Management for a Patient with Advanced Dementia

      When managing pain in a patient with advanced dementia, it is important to consider their impaired mental status and potential swallowing difficulties. In this case, per rectum delivery of paracetamol 1 g would be appropriate to avoid the risk of aspiration pneumonia. Intravenous delivery of medication would be more invasive and potentially distressing for the patient.

      While a lidocaine patch may be useful for localized pain management in the elderly, it would not be the first choice for this patient. Morphine sulfate and fentanyl patch transdermal are strong opioid medications and should only be considered if milder analgesia fails to achieve pain control, in line with the World Health Organisation pain ladder. Overall, the choice of pain management should prioritize the patient’s comfort and safety.

    Incorrect

    • You are requested to examine a 65-year-old man at your clinic. He was diagnosed with an abdominal aortic aneurysm (AAA) 18 months ago after being invited to the national screening program. The aneurysm was initially measured at 4.5 cm in diameter. He has recently undergone his follow-up scan and was informed that his aneurysm has now increased to 5.8 cm in diameter. The patient is asymptomatic and feels healthy.
      What would be the most suitable course of action for managing this patient?

      Your Answer: Increase ultrasound surveillance to every 3 months

      Correct Answer: Two week wait referral to vascular surgery for repair

      Explanation:

      If an aneurysm is rapidly enlarging, regardless of its size, it should be repaired even if the patient is asymptomatic. In this case, the patient’s AAA was detected through a one-time screening program for males at 65 years of age. Although the aneurysm is still below the referral threshold of 5.5 cm, it has grown more than 1.0cm in one year, necessitating an urgent referral to vascular surgery via the two-week wait pathway for repair.

      Discharging the patient from yearly ultrasound surveillance is not recommended, as continued monitoring is necessary. Yearly ultrasound surveillance is appropriate for aneurysms measuring 3-4.4 cm or if the aneurysm has grown. Increasing the frequency of ultrasound surveillance to every 3 months is appropriate for aneurysms measuring 4.5-5.4 cm, but in this case, urgent referral for repair is necessary due to the substantial growth of the aneurysm.

      Although the patient is not displaying symptoms of aneurysm rupture, emergency repair is not appropriate.

      Abdominal aortic aneurysm (AAA) is a condition that often develops without any symptoms. However, a ruptured AAA can be fatal, which is why it is important to screen patients for this condition. Screening involves a single abdominal ultrasound for males aged 65. The results of the screening are interpreted based on the width of the aorta. If the width is less than 3 cm, no further action is needed. If it is between 3-4.4 cm, the patient should be rescanned every 12 months. For a width of 4.5-5.4 cm, the patient should be rescanned every 3 months. If the width is 5.5 cm or more, the patient should be referred to vascular surgery within 2 weeks for probable intervention.

      For patients with a low risk of rupture, which includes those with a small or medium aneurysm (i.e. aortic diameter less than 5.5 cm) and no symptoms, abdominal US surveillance should be conducted on the time-scales outlined above. Additionally, cardiovascular risk factors should be optimized, such as quitting smoking. For patients with a high risk of rupture, which includes those with a large aneurysm (i.e. aortic diameter of 5.5 cm or more) or rapidly enlarging aneurysm (more than 1 cm/year) or those with symptoms, they should be referred to vascular surgery within 2 weeks for probable intervention. Treatment for these patients may involve elective endovascular repair (EVAR) or open repair if EVAR is not suitable. EVAR involves placing a stent into the abdominal aorta via the femoral artery to prevent blood from collecting in the aneurysm. However, a complication of EVAR is an endo-leak, which occurs when the stent fails to exclude blood from the aneurysm and usually presents without symptoms on routine follow-up.

He has consulted with a dermatologist who has assured him that it is a benign pigmented nevus, but the patient remains convinced that he will develop skin cancer. What is the term for neurotic anxiety related to a serious medical condition that cannot be alleviated by medical reassurance, assuming there are no other significant psychiatric disorders present?

      Your Answer: Somatisation disorder

      Correct Answer: Hypochondriasis

      Explanation:

      Differentiating between disorders related to illness and pain

      There are several disorders related to illness and pain that can be difficult to differentiate. Hypochondriasis, also known as Illness anxiety disorder, is characterized by excessive fear of having or developing a disease. Malingering, on the other hand, involves faking or causing disease to escape obligations or obtain monetary rewards.

      Somatisation disorder is diagnosed when a patient experiences symptoms for at least two years and seeks reassurance from multiple healthcare professionals, impacting their social and family functioning. Pain disorder is characterized by experiencing pain without obvious physical basis or exceeding the normal distress associated with an illness.

      Finally, Munchausen syndrome is a severe form of factitious disorder where patients present with dramatic, faked, or induced physical or psychological complaints and even submit to unwarranted invasive treatments. It is important to differentiate between these disorders to provide appropriate treatment and support.

What is the most suitable blood test to conduct?

      Your Answer: Activated Partial Thromboplastin Time (APTT)

      Correct Answer: Anti-Factor Xa levels

      Explanation:

      Understanding Heparin and its Adverse Effects

      Heparin is a type of anticoagulant that comes in two forms: unfractionated or standard heparin, and low molecular weight heparin (LMWH). Both types work by activating antithrombin III, but unfractionated heparin inhibits thrombin, factors Xa, IXa, XIa, and XIIa, while LMWH only increases the action of antithrombin III on factor Xa. However, heparin can cause adverse effects such as bleeding, thrombocytopenia, osteoporosis, and hyperkalemia.

      Heparin-induced thrombocytopenia (HIT) is a condition where antibodies form against complexes of platelet factor 4 (PF4) and heparin, leading to platelet activation and a prothrombotic state. HIT usually develops after 5-10 days of treatment and is characterized by a greater than 50% reduction in platelets, thrombosis, and skin allergy. To address the need for ongoing anticoagulation, direct thrombin inhibitors like argatroban and danaparoid can be used.

      Standard heparin is administered intravenously and has a short duration of action, while LMWH is administered subcutaneously and has a longer duration of action. Standard heparin is useful in situations where there is a high risk of bleeding as anticoagulation can be terminated rapidly, while LMWH is now standard in the management of venous thromboembolism treatment and prophylaxis and acute coronary syndromes. Monitoring for standard heparin is done through activated partial thromboplastin time (APTT), while LMWH does not require routine monitoring. Heparin overdose may be reversed by protamine sulfate, although this only partially reverses the effect of LMWH.

      Of the following diseases, which is best described as being inherited in an autosomal recessive pattern?

      Your Answer: Cystic fibrosis

      Explanation:

      Genetic Disorders: Causes, Symptoms, and Inheritance Patterns

      Cystic Fibrosis, Von Willebrand’s Disease, Familial Polyposis Coli, Duchenne Muscular Dystrophy, and Haemophilia B are all genetic disorders with distinct causes, symptoms, and inheritance patterns.

      Cystic Fibrosis is the most common autosomal recessive disease in white populations, caused by mutations in the CFTR gene. It affects the respiratory, digestive, and reproductive systems, leading to chronic lung infections, malabsorption, and infertility.

      Von Willebrand’s Disease is inherited in an autosomal dominant manner, caused by mutations in the vWF gene. It impairs primary haemostasis, leading to easy bruising, prolonged bleeding after minor trauma, nosebleeds, and menorrhagia.

      Familial Polyposis Coli is an autosomal dominant disorder caused by mutations in the APC gene. It leads to the formation of hundreds to thousands of polyps throughout the colon and rectum, which can progress to cancer if left untreated.

      Duchenne Muscular Dystrophy is X-linked recessive, caused by a mutation in the dystrophin gene. It affects mainly males, leading to progressive proximal muscular dystrophy, calf pseudohypertrophy, fatigue, difficulty with motor skills, and reduced life expectancy.

      Haemophilia B is X-linked recessive, caused by a mutation in the factor IX gene. It leads to problems with haemostasis, causing haemorrhage into the joints, severe bleeding following minor trauma or procedures, and oral bleeding.

      Understanding the causes, symptoms, and inheritance patterns of genetic disorders is crucial for early diagnosis, management, and genetic counselling.

    Correct

    • A 25-year-old female presents with sudden onset of abdominal pain. Upon examination, her abdomen is found to be tender all over. Laparoscopy reveals the presence of numerous small lesions between her liver and abdominal wall, while her appendix appears to be unaffected. What is the most probable diagnosis?

      Your Answer: Pelvic inflammatory disease (Fitz-Hugh-Curtis)

      Explanation:

      Fitz-Hugh-Curtis syndrome is characterized by hepatic adhesions, which are not present in any of the other options. Therefore, the diagnosis is based on the presence of lesions rather than just the symptoms described. This syndrome is a complication of PID that causes inflammation of the liver capsule, known as Glisson’s Capsule.

      Gynaecological Causes of Abdominal Pain in Women

      Abdominal pain is a common complaint among women, and it can be caused by various gynaecological disorders. To diagnose these disorders, a bimanual vaginal examination, urine pregnancy test, and abdominal and pelvic ultrasound scanning should be performed in addition to routine diagnostic workup. If diagnostic doubt persists, a laparoscopy can be used to assess suspected tubulo-ovarian pathology.

      There are several differential diagnoses of abdominal pain in females, including mittelschmerz, endometriosis, ovarian torsion, ectopic gestation, and pelvic inflammatory disease. Mittelschmerz is characterized by mid-cycle pain that usually settles over 24-48 hours. Endometriosis is a complex disease that may result in pelvic adhesional formation with episodes of intermittent small bowel obstruction. Ovarian torsion is usually sudden onset of deep-seated colicky abdominal pain associated with vomiting and distress. Ectopic gestation presents as an emergency with evidence of rupture or impending rupture. Pelvic inflammatory disease is characterized by bilateral lower abdominal pain associated with vaginal discharge and dysuria.

      Each of these disorders requires specific investigations and treatments. For example, endometriosis is usually managed medically, but complex disease may require surgery and some patients may even require formal colonic and rectal resections if these areas are involved. Ovarian torsion is usually diagnosed and treated with laparoscopy. Ectopic gestation requires a salpingectomy if the patient is haemodynamically unstable. Pelvic inflammatory disease is usually managed medically with antibiotics.

    Correct

    • Samantha is a 65-year-old woman who loves going on hikes and spends a lot of time tending to her flower garden. Unfortunately, she recently fell and suffered an undisplaced intracapsular neck of femur fracture. What is the best course of action for managing Samantha's hip fracture?

      Your Answer: Internal fixation (cannulated hip screw)

      Explanation:

      When dealing with an intracapsular NOF fracture, internal fixation is the preferred method for patients who have a good pre-existing functional ability. This is crucial in determining the appropriate course of action. Conservative management is not recommended due to the risk of avascular necrosis. Surgical intervention is typically necessary for most patients. Hemiarthroplasty is typically reserved for patients with poor pre-existing functioning, while total hip replacements are used for displaced intracapsular fractures. Cannulated hip screws are commonly used for internal fixation, while intramedullary devices are used for extracapsular fractures.

      Hip fractures are a common occurrence, particularly in elderly women with osteoporosis. The femoral head’s blood supply runs up the neck, making avascular necrosis a potential risk in displaced fractures. Symptoms of a hip fracture include pain and a shortened and externally rotated leg. Patients with non-displaced or incomplete neck of femur fractures may still be able to bear weight. Hip fractures can be classified as intracapsular or extracapsular, with the Garden system being a commonly used classification system. Blood supply disruption is most common in Types III and IV fractures.

      Intracapsular hip fractures can be treated with internal fixation or hemiarthroplasty if the patient is unfit. Displaced fractures are recommended for replacement arthroplasty, such as total hip replacement or hemiarthroplasty, according to NICE guidelines. Total hip replacement is preferred over hemiarthroplasty if the patient was able to walk independently outdoors with the use of a stick, is not cognitively impaired, and is medically fit for anesthesia and the procedure. Extracapsular hip fractures can be managed with a dynamic hip screw for stable intertrochanteric fractures or an intramedullary device for reverse oblique, transverse, or subtrochanteric fractures.

Her heart rate is 88 bpm and blood pressure is 130/85 mmHg. The patient flew from Dubai to the UK yesterday. She has type I diabetes mellitus which is well managed. She had a tonsillectomy two years ago and her brother has asthma. She has been taking the combined oral contraceptive pill for six months and uses insulin for her diabetes but takes no other medications.
      What is the most significant risk factor for the likely diagnosis?

      Your Answer: Diabetes

      Correct Answer: Combined oral contraceptive pill

      Explanation:

      Assessing Risk Factors for Pulmonary Embolism in a Patient with Sudden Onset of Symptoms

      This patient presents with sudden onset of shortness of breath, chest pain, and haemoptysis, suggesting a pulmonary embolism. A history of long-haul flight and use of combined oral contraceptive pill further increase the risk for this condition. However, tonsillectomy two years ago is not a current risk factor. Type I diabetes mellitus and asthma are also not associated with pulmonary embolism. A family history of malignancy may increase the risk for developing a malignancy, which in turn increases the risk for pulmonary embolism. Overall, a thorough assessment of risk factors is crucial in identifying and managing pulmonary embolism in patients with acute symptoms.

      On examination, there is a firm lump lying in the body of the left testicle. His body mass index is 27. There are a few left-sided inguinal lymph nodes palpable. You suspect testicular cancer.
      Which of the following findings on history and examination makes this provisional diagnosis more likely?

      Your Answer: A history of raised BMI

      Correct Answer: History of orchidopexy for an undescended testicle

      Explanation:

      Understanding the Risk Factors and Symptoms of Testicular Cancer

      Testicular cancer is a serious condition that can have life-altering consequences if not detected and treated early. One of the main risk factors for this type of cancer is a history of undescended testes, which increases the risk significantly. Additionally, men with a high body mass index may have a lower risk of developing testicular cancer.

      It’s important to note that the presence or absence of tenderness in the testicles does not necessarily indicate the presence of cancer. However, any man who notices a lump or mass in the body of the testicle should seek urgent medical attention to rule out the possibility of cancer.

      In terms of metastasis, testicular cancer commonly spreads to the para-aortic lymph nodes rather than the inguinal nodes. By understanding these risk factors and symptoms, men can take proactive steps to protect their health and detect any potential issues early on.

The son believes that his mother’s Alzheimer’s dementia has worsened considerably in the last few months. He observes that his mother is becoming more forgetful and is struggling with dressing and eating regular meals. The specialist evaluates the patient and decides to initiate memantine treatment.
      What is a typical adverse effect of memantine?

      Your Answer: Headaches

      Explanation:

      Understanding the Side-Effects of Memantine

      Memantine is a medication commonly used for the treatment of Alzheimer’s disease. As an N-methyl-D-aspartate (NMDA) antagonist, it works by reducing levels of glutamate in the brain. While it can be effective in managing symptoms, it is important to be aware of potential side-effects.

      One common side-effect of memantine is headaches. Other possible adverse effects include constipation, abnormal gait, hypertension, and central nervous system issues such as psychosis and suicidal ideation. However, it is important to note that Parkinsonism and Mobitz type II block are not known side-effects of this medication.

      It is also worth noting that memantine can cause hypertension rather than hypotension, and may lead to constipation rather than diarrhoea. By understanding the potential side-effects of memantine, patients and healthcare providers can work together to manage symptoms and ensure the best possible outcomes.

    • What is a common side effect of olanzapine?

      Your Answer: Akathisia

      Explanation:

      Side Effects of Olanzapine

      Olanzapine, an atypical antipsychotic, is known to cause several side effects. One of the most common side effects is akathisia, which is characterized by restlessness and an inability to sit still. Other side effects associated with the use of olanzapine include agranulocytosis, hyperprolactinaemia, hyperglycaemia, depression, and anxiety. Agranulocytosis is a condition where the body’s immune system is unable to produce enough white blood cells, which can lead to infections. Hyperprolactinaemia is a condition where the body produces too much of the hormone prolactin, which can cause breast enlargement and lactation in both men and women. Hyperglycaemia is a condition where the body has high levels of glucose in the blood, which can lead to diabetes. Depression and anxiety are also common side effects of olanzapine, which can be particularly problematic for individuals with pre-existing mental health conditions. It is important to be aware of these potential side effects when taking olanzapine and to speak with a healthcare provider if any concerns arise.

      1. Candida albicans: This fungal infection can cause candidiasis, which presents with a thick, cottage-cheese yellowish discharge and pain upon urination. Treatment involves antifungal medication.

      2. Normal discharge: A normal vaginal discharge is clear and mucoid, without smell or other concerning symptoms.

      3. gonorrhoeae: This sexually transmitted infection caused by Neisseria gonorrhoeae can cause a thick green-yellow discharge, painful urination, and bleeding between periods.

      4. Chlamydia: This common sexually transmitted infection is often asymptomatic but can eventually cause pain upon urination, vaginal/penile discharge, and bleeding between periods.

      5. Bacterial vaginosis: This infection is caused by an overgrowth of bacteria in the vagina and presents with a grey, watery discharge with a fishy odor. Treatment involves antibiotics and topical gels or creams.

      It is important to seek medical attention if you experience any concerning symptoms or suspect a vaginal infection.

    Correct

    • A 25-year-old female presents to the emergency department with tenderness over the lateral aspect of her midfoot after slipping off a kerb while walking. She is having difficulty walking and a radiograph reveals a fracture of the 5th metatarsal. What is the most probable mechanism of action that caused this fracture?

      Your Answer: Inversion of the foot and ankle

      Explanation:

      Fractures of the 5th metatarsal are commonly caused by the foot and ankle being forcefully inverted. These types of fractures are often seen in athletes, including dancers, football players, and rugby players, but can also occur from minor incidents such as stepping off a curb. Avulsion fractures are a specific type of 5th metatarsal fracture that result from the peroneus brevis muscle pulling on the proximal part of the bone during foot inversion. It is important to note that 5th metatarsal fractures are not associated with any other movements of the ankle or hip.

      Metatarsal fractures are a common occurrence, with the potential to affect one or multiple metatarsals. These fractures can result from direct trauma or repeated mechanical stress, known as stress fractures. The metatarsals are particularly susceptible to stress fractures, with the second metatarsal shaft being the most common site. The proximal 5th metatarsal is the most commonly fractured metatarsal, while the 1st metatarsal is the least commonly fractured.

      Fractures of the proximal 5th metatarsal can be classified as either proximal avulsion fractures or Jones fractures. Proximal avulsion fractures occur at the proximal tuberosity and are often associated with lateral ankle sprains. Jones fractures, on the other hand, are transverse fractures at the metaphyseal-diaphyseal junction and are much less common.

      Symptoms of metatarsal fractures include pain, bony tenderness, swelling, and an antalgic gait. X-rays are typically used to distinguish between displaced and non-displaced fractures, which guides subsequent management options. However, stress fractures may not appear on X-rays and may require an isotope bone scan or MRI to establish their presence. Overall, metatarsal fractures are a common injury that can result from a variety of causes and require prompt diagnosis and management.

    • A 35-year-old man is brought to the Emergency department following a house fire. He appears lethargic, but his cheeks have a pinkish hue and he seems to be well perfused. His blood pressure is 100/60 mmHg and his pulse is 95 and regular. Upon blood gas analysis, a CO level of 12% and metabolic acidosis with a pH of 7.15 are detected. What is the most suitable next step in management?

      Your Answer: Hyperbaric oxygen

      Correct Answer: 100% oxygen by mask

      Explanation:

      Treatment for Carbon Monoxide Poisoning

      Carbon monoxide poisoning is a serious condition that requires prompt treatment. The recommended treatment is 100% oxygen by mask. Although some countries, such as the United States, recommend hyperbaric oxygen, it is not standard practice in the United Kingdom due to a lack of randomized control evidence. High flow oxygen alone appears to be just as effective. Sodium bicarbonate is not indicated, and IV mannitol is only used if there is suspicion of cerebral edema. The key to a good prognosis is removing the patient from the source of carbon monoxide as quickly as possible and starting high flow oxygen treatment. Long-term psychological disturbance or memory loss is possible if the level of carbon monoxide is at 12% or higher.

    • A 54-year-old female with a history of rheumatoid arthritis visited her GP complaining of redness in her right eye. She mentioned experiencing mild discomfort and irritation with occasional watering of the eye. However, she denied any dryness or significant pain. The examination of her pupils revealed no abnormalities, and she did not experience any discomfort when exposed to light. What is the probable diagnosis?

      Your Answer: Keratitis

      Correct Answer: Episcleritis

      Explanation:

      Rheumatoid Arthritis and Its Effects on the Eyes

      Rheumatoid arthritis is a chronic autoimmune disease that affects various parts of the body, including the eyes. In fact, ocular manifestations of rheumatoid arthritis are quite common, with approximately 25% of patients experiencing eye problems. These eye problems can range from mild to severe and can significantly impact a patient’s quality of life.

      The most common ocular manifestation of rheumatoid arthritis is keratoconjunctivitis sicca, also known as dry eye syndrome. This condition occurs when the eyes do not produce enough tears, leading to discomfort, redness, and irritation. Other ocular manifestations of rheumatoid arthritis include episcleritis, scleritis, corneal ulceration, and keratitis. Episcleritis and scleritis both cause redness in the eyes, with scleritis also causing pain. Corneal ulceration and keratitis both affect the cornea, with corneal ulceration being a more severe condition that can lead to vision loss.

      In addition to these conditions, patients with rheumatoid arthritis may also experience iatrogenic ocular manifestations. These are side effects of medications used to treat the disease. For example, steroid use can lead to cataracts, while the use of chloroquine can cause retinopathy.

      Overall, it is important for patients with rheumatoid arthritis to be aware of the potential ocular manifestations of the disease and to seek prompt medical attention if they experience any eye-related symptoms. Early diagnosis and treatment can help prevent vision loss and improve overall quality of life.

    Correct

    • A 50-year-old woman visits her GP to receive the results of her recent cervical smear. Her two previous smears, taken 18 and 6 months ago, were positive for high-risk human papillomavirus (HPV) but showed no abnormal cytology. The GP informs her that her most recent cervical smear also tested positive for high-risk HPV. What is the best course of action for managing this patient?

      Your Answer: Refer for colposcopy

      Explanation:

      If a patient’s 2nd repeat cervical smear at 24 months is still positive for high-risk human papillomavirus (hrHPV), the correct course of action is to refer them for colposcopy. This is in line with the NHS cervical screening programme guidelines.

      Cytological examination of the smear would not change the management of the patient and is therefore not the correct option. Regardless of cytological findings, a patient with a third hrHPV positive smear would be referred for colposcopy.

      Repeating the cervical smear in 5 years is not appropriate for this patient as it is only recommended for those with negative hrHPV results.

      Repeating the cervical smear after 6 months is not indicated as a test of cure for cervical intraepithelial neoplasia in this case.

      Repeating the cervical smear after 12 months is also not appropriate as this is the patient’s 2nd repeat smear that is hrHPV positive. It would only be considered if it was their routine smear or 1st repeat smear that was hrHPV positive and there were no cytological abnormalities.

      The cervical cancer screening program has evolved to include HPV testing, which allows for further risk stratification. A negative hrHPV result means a return to normal recall, while a positive result requires cytological examination. Abnormal cytology results lead to colposcopy, while normal cytology results require a repeat test at 12 months. Inadequate samples require a repeat within 3 months, and two consecutive inadequate samples lead to colposcopy. Treatment for CIN typically involves LLETZ or cryotherapy. Individuals who have been treated for CIN should be invited for a test of cure repeat cervical sample 6 months after treatment.

    • A 42-year-old teacher from Manchester presents to her GP with a 3 month history of nonspecific upper right quadrant pain and nausea. The pain is constant, not radiating, and not affected by food. She denies any changes in bowel habits, weight loss, or fever. She drinks approximately 8 units of alcohol per week, is a non-smoker, and has no significant medical history. The GP orders blood tests and a liver ultrasound, with the following results:

      Full blood count, electrolytes, liver function tests, and clotting profile are all within normal limits.
      HBs antigen is negative.
      Anti-HBs is positive.
      Anti-HBc is negative.
      IgM anti-HBc is negative.
      Ultrasound reveals a single 11cm x 8 cm hyperechoic lesion in the right lobe of the liver, without other abnormalities detected and no biliary tree abnormalities noted.

      What is the most likely cause of this patient's symptoms?

      Your Answer: Hepatocellular carcinoma

      Correct Answer: Hepatic haemangioma

      Explanation:

      Haemangiomas are benign liver growths that are usually small and do not increase in size over time. However, larger growths can cause symptoms by pressing on nearby structures, such as the stomach or biliary tree. Symptoms may include early satiety, nausea, obstructive jaundice, and right upper quadrant pain. Hepatic haemangiomas are more common than hepatocellular carcinomas in Western populations without risk factors. The presence of anti-HBs indicates previous hepatitis immunisation or immunity, which is likely for a UK phlebotomist. Symptoms of biliary colic and peptic ulcer disease typically vary with food intake, and ultrasound can detect biliary pathology such as gallbladder thickening or the presence of stones.

      Benign liver lesions are non-cancerous growths that can occur in the liver. One of the most common types of benign liver tumors is a haemangioma, which is a reddish-purple hypervascular lesion that is typically separated from normal liver tissue by a ring of fibrous tissue. Liver cell adenomas are another type of benign liver lesion that are usually solitary and can be linked to the use of oral contraceptive pills. Mesenchymal hamartomas are congenital and benign, and usually present in infants. Liver abscesses can also occur, and are often caused by biliary sepsis or infections in structures drained by the portal venous system. Amoebic abscesses are a type of liver abscess that are caused by amoebiasis, and are typically seen in the right lobe of the liver. Hydatid cysts are another type of benign liver lesion that are caused by Echinococcus infection, and can grow up to 20 cm in size. Polycystic liver disease is a condition that is usually associated with polycystic kidney disease, and can cause symptoms as a result of capsular stretch. Cystadenomas are rare benign liver lesions that have malignant potential and are usually solitary multiloculated lesions. Surgical resection is often indicated for the treatment of these lesions.

    Incorrect

    • A 30-year-old woman visits her GP complaining of vaginal itching and a change in discharge. She has been experiencing thick, white discharge for the past 3 days and the itching has become unbearable today. She is sexually active with her partner and takes the combined oral contraceptive pill. She denies having a fever, abdominal pain, painful intercourse, or any new sexual partners. What is the most suitable course of action for managing the probable diagnosis?

      Your Answer: Oral nystatin once daily for 3 days

      Correct Answer: Oral fluconazole single dose

      Explanation:

      The recommended first-line treatment for non-pregnant women with symptoms of vaginal thrush, such as a curd-like discharge and itching, is a single dose of oral fluconazole. This medication can often be obtained directly from a pharmacist without needing to see a GP. Using low dose topical corticosteroids until symptoms improve is not an appropriate treatment for managing the fungal infection. Similarly, taking oral cetirizine daily for two weeks is not the recommended course of action, although it may be used for treatment-resistant thrush. Oral fluconazole should be tried first before considering cetirizine. Lastly, a three-day course of oral fluconazole is not the appropriate duration of treatment for this patient population.

      Vaginal candidiasis, also known as thrush, is a common condition that many women can diagnose and treat themselves. Candida albicans is responsible for about 80% of cases, while other candida species cause the remaining 20%. Although most women have no predisposing factors, certain factors such as diabetes mellitus, antibiotics, steroids, pregnancy, and HIV can increase the likelihood of developing vaginal candidiasis. Symptoms include non-offensive discharge resembling cottage cheese, vulvitis, itching, vulval erythema, fissuring, and satellite lesions. A high vaginal swab is not routinely indicated if the clinical features are consistent with candidiasis. Treatment options include local or oral therapy, with oral fluconazole 150 mg as a single dose being the first-line treatment according to NICE Clinical Knowledge Summaries. If there are vulval symptoms, a topical imidazole may be added to an oral or intravaginal antifungal. Pregnant women should only use local treatments. Recurrent vaginal candidiasis is defined as four or more episodes per year by BASHH. Compliance with previous treatment should be checked, and a high vaginal swab for microscopy and culture should be performed to confirm the diagnosis. A blood glucose test may be necessary to exclude diabetes, and differential diagnoses such as lichen sclerosus should be ruled out. An induction-maintenance regime involving oral fluconazole may be considered. Induction involves taking oral fluconazole every three days for three doses, while maintenance involves taking oral fluconazole weekly for six months.

    • A 47-year-old accountant visits his GP seeking advice. He has been experiencing a gradual loss of coordination over the past year and has recently been diagnosed with Huntington's disease. He has been researching the condition online and wants to discuss his findings further. What is the most appropriate inheritance pattern for Huntington's disease?

      Your Answer: Autosomal dominant

      Explanation:

      Inheritance Patterns of Genetic Disorders

      Genetic disorders can be inherited in different patterns, including autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. Huntington’s disease is an example of an autosomal dominant disorder, which affects chromosome 4 and is caused by a CAG triplet repeat. The severity of the disease depends on the number of repeats, with 41 or more being fully penetrant. Mitochondrial disorders are inherited from the mother only, and Kearns-Sayre syndrome is an example of this type. Autosomal recessive disorders require both parents to be carriers, and examples include sickle cell anemia and cystic fibrosis. X-linked dominant disorders are more common in females, while X-linked recessive disorders, such as Duchenne muscular dystrophy, are more common in males. Huntington’s disease is not inherited in an X-linked fashion.

    • A 63-year-old man comes to the emergency department complaining of 'flutters in his chest' for the past 24 hours. He is aware of when his symptoms started and mentions having had 2 non-ST-elevation myocardial infarctions before. He has hypertension, which is controlled with perindopril monotherapy, and hypercholesterolaemia treated with atorvastatin. He has no other relevant medical history.

      During the examination, the patient is alert and oriented. His blood pressure is 135/90 mmHg, heart rate is 112 beats per minute, temperature is 37.3ºC, and respiratory rate is 16 breaths per minute. An ECG shows an irregularly irregular rhythm. After discussing with the patient, a management plan is suggested.

      What is the most likely management plan to be initiated for this patient based on his presentation?

      Your Answer: Begin anticoagulation, undergo immediate direct current (DC) cardioversion

      Explanation:

      When a patient presents with new-onset atrial fibrillation (AF), the management plan depends on the duration and recurrence of symptoms, as well as risk stratification. If symptoms have been present for less than 48 hours, electrical cardioversion is recommended, but anticoagulation should be started beforehand. Heparin is a good choice for rapid onset anticoagulation. However, if symptoms have been present for more than 48 hours, there is a higher risk of atrial thrombus, which may cause thromboembolic disease. In this case, a transoesophageal echocardiogram (TOE) should be obtained to exclude a thrombus before cardioversion, or anticoagulation should be started for 3 weeks prior to cardioversion. Amiodarone oral therapy is not adequate for cardioversion in acute AF. If cardioversion is not possible, a DOAC such as apixaban or rivaroxaban should be started. Discharge home is appropriate for patients with chronic AF or after cardioversion. While pharmacological cardioversion with intravenous amiodarone is an option, electrical cardioversion is preferred according to NICE guidelines, especially in patients with structural heart disease.

      Atrial Fibrillation and Cardioversion: Elective Procedure for Rhythm Control

      Cardioversion is a medical procedure used in atrial fibrillation (AF) to restore the heart’s normal rhythm. There are two scenarios where cardioversion may be used: as an emergency if the patient is haemodynamically unstable, or as an elective procedure where a rhythm control strategy is preferred. In the elective scenario, cardioversion can be performed either electrically or pharmacologically. Electrical cardioversion is synchronised to the R wave to prevent delivery of a shock during the vulnerable period of cardiac repolarisation when ventricular fibrillation can be induced.

      According to the 2014 NICE guidelines, rate or rhythm control should be offered if the onset of the arrhythmia is less than 48 hours, and rate control should be started if it is more than 48 hours or is uncertain. If the AF is definitely of less than 48 hours onset, patients should be heparinised and may be cardioverted using either electrical or pharmacological means. However, if the patient has been in AF for more than 48 hours, anticoagulation should be given for at least 3 weeks prior to cardioversion. An alternative strategy is to perform a transoesophageal echo (TOE) to exclude a left atrial appendage (LAA) thrombus. If excluded, patients may be heparinised and cardioverted immediately.

      NICE recommends electrical cardioversion in this scenario, rather than pharmacological. If there is a high risk of cardioversion failure, it is recommended to have at least 4 weeks of amiodarone or sotalol prior to electrical cardioversion. Following electrical cardioversion, patients should be anticoagulated for at least 4 weeks. After this time, decisions about anticoagulation should be taken on an individual basis depending on the risk of recurrence.

    • A 65-year-old man with rheumatoid arthritis is scheduled for a procedure at the day surgery unit. The surgery is aimed at treating carpal tunnel syndrome. During the procedure, which structure is divided to decompress the median nerve?

      Your Answer: Flexor retinaculum

      Explanation:

      The flexor retinaculum is the only structure that is divided in the surgical treatment of carpal tunnel syndrome. It is important to protect all other structures during the procedure as damaging them could result in further injury or disability. The purpose of dividing the flexor retinaculum is to decompress the median nerve.

      Understanding Carpal Tunnel Syndrome

      Carpal tunnel syndrome is a condition that occurs when the median nerve in the carpal tunnel is compressed. Patients with this condition typically experience pain or pins and needles in their thumb, index, and middle fingers. In some cases, the symptoms may even ascend proximally. Patients often shake their hand to obtain relief, especially at night.

      During an examination, doctors may observe weakness of thumb abduction and wasting of the thenar eminence (not the hypothenar). Tapping on the affected area may cause paraesthesia, which is known as Tinel’s sign. Flexion of the wrist may also cause symptoms, which is known as Phalen’s sign.

      Carpal tunnel syndrome can be caused by a variety of factors, including idiopathic reasons, pregnancy, oedema (such as heart failure), lunate fracture, and rheumatoid arthritis. Electrophysiology tests may show prolongation of the action potential in both motor and sensory nerves.

      Treatment for carpal tunnel syndrome may include a 6-week trial of conservative treatments, such as corticosteroid injections and wrist splints at night. If symptoms persist or are severe, surgical decompression (flexor retinaculum division) may be necessary.

    • A 50-year-old female patient visits the clinic with complaints of abdominal discomfort and bloating that have been progressively worsening over the past few months. Upon examination, her GP discovered a complex left ovarian cyst. Which blood test would be the most useful in determining if the cyst is cancerous?

      Your Answer: Carcino-embryonic antigen

      Correct Answer: CA125

      Explanation:

      Tumor Markers and Their Association with Different Cancers

      Tumor markers are substances that are produced by cancer cells or by normal cells in response to cancer. These markers can be used to detect the presence of cancer, monitor the progress of treatment, and detect the recurrence of cancer. One such tumor marker is CA125, which is associated with ovarian carcinoma. However, elevations in CA125 can also be seen in uterine cancer, pancreas, stomach, and colonic tumors. In some cases, benign ovarian tumors can also cause a rise in CA125 levels. If a patient has a CA125 level of over 200U/ml and an abnormal ultrasound scan, it is highly likely that they have ovarian carcinoma.

      Other tumor markers include CA19-9, which is primarily associated with pancreatic tumors, beta-HCG, which is associated with germ cell tumors, alpha-fetoprotein, which is associated with hepatocellular carcinoma, and carcinoembryonic antigen, which is associated with colonic carcinoma. While AFP and beta-HCG can rarely be secreted by ovarian tumors, it is important to check CA125 levels first, as they are much more frequently elevated. By monitoring tumor markers, doctors can detect cancer early and provide appropriate treatment.

    • A 56-year-old woman presents to the clinic with a 6-month history of excessive thirst and abdominal pain. Her medical history is unremarkable, without previous vitamin D deficiency or chronic kidney disease. Upon examination, no other abnormalities were found. Blood tests reveal a hemoglobin level of 128 g/L, platelets at 168 * 109/L, and a white blood cell count of 6.2 * 109/L. Her sodium and potassium levels are within normal range, but her urea and creatinine levels are elevated at 8.8 mmol/L and 130 µmol/L, respectively. Additionally, her calcium level is high at 2.8 mmol/L, while her phosphate level is low at 0.7 mmol/L. Her parathyroid hormone level is also elevated at 10.2 pmol/L. What is the most likely diagnosis?

      Your Answer: Tertiary hyperparathyroidism

      Correct Answer: Primary hyperparathyroidism

      Explanation:

      Secondary hyperparathyroidism is not the correct diagnosis. This condition occurs as a natural response to low levels of calcium in the body. The most common causes of secondary hyperparathyroidism are kidney failure and vitamin D deficiency, which would result in low calcium levels and elevated levels of PTH.

      Lab Values for Bone Disorders

      When it comes to bone disorders, certain lab values can provide important information for diagnosis and treatment. In cases of osteoporosis, calcium, phosphate, alkaline phosphatase (ALP), and parathyroid hormone (PTH) levels are typically within normal ranges. However, in osteomalacia, there is a decrease in calcium and phosphate levels, an increase in ALP levels, and an increase in PTH levels.

      Primary hyperparathyroidism, which can lead to osteitis fibrosa cystica, is characterized by increased calcium and PTH levels, but decreased phosphate levels. Chronic kidney disease can also lead to secondary hyperparathyroidism, with decreased calcium levels and increased phosphate and PTH levels.

      Paget’s disease, which causes abnormal bone growth, typically shows normal calcium and phosphate levels, but an increase in ALP levels. Osteopetrosis, a rare genetic disorder that causes bones to become dense and brittle, typically shows normal lab values for calcium, phosphate, ALP, and PTH.

      Overall, understanding these lab values can help healthcare professionals diagnose and treat various bone disorders.

      When to Prescribe Oxygen Therapy for COPD Patients: Indications and Limitations

      Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition that can lead to hypoxia, or low oxygen levels in the blood. Oxygen therapy is a common treatment for COPD patients with hypoxia, but it is not appropriate for all cases. Here are some indications and limitations for prescribing oxygen therapy for COPD patients:

      Indication: PaO2 < 7.3 kPa when stable or PaO2 > 7.3 and < 8 kPa when stable with secondary polycythaemia, nocturnal hypoxaemia, peripheral oedema, or pulmonary hypertension present. Patients should meet the criteria on at least two blood gases taken when stable at least three weeks apart. Limitation: Oxygen therapy would have no impact on the frequency of acute exacerbations and would not be appropriate to prescribe for this indication. Indication: Symptomatic desaturation on exertion. Ambulatory oxygen may be prescribed if the presence of oxygen results in an increase in exercise capacity and/or dyspnoea. Limitation: There is no evidence that oxygen therapy is of benefit in patients with severe breathlessness who are not significantly hypoxic at rest or on exertion. Management options would include investigating for other potential causes of breathlessness and treating as appropriate, or reviewing inhaled and oral medication for COPD and pulmonary rehabilitation. Indication: PaO2 < 8.5 kPa when stable with secondary polycythaemia, peripheral oedema, or pulmonary hypertension present. There is no evidence of survival benefit if patients with a PaO2 > 8 kPa are prescribed oxygen therapy.

      In summary, oxygen therapy is a valuable treatment for COPD patients with hypoxia, but it should be prescribed with caution and based on specific indications and limitations.

He has been on dialysis for the past nine years and uses a fistula for the procedure. So far, there have been no issues with the dialysis machine or circuit. After the session, his blood pressure is 150/85 mmHg, and an ECG is performed. What could be the probable reason for his chest pain?

      Your Answer: Air embolism

      Correct Answer: Acute coronary syndrome

      Explanation:

      Acute coronary syndrome is the most common cause of chest pain and shortness of breath in dialysis patients due to their increased risk of coronary disease. Air embolism, hypotension, massive haemolysis, and pulmonary embolism are also possible causes but are less likely. Air embolism is rare but can occur in patients with central lines, while hypotension is more common in the elderly and new starters on dialysis. Massive haemolysis is rare but serious, and pulmonary embolism can occur if there is a known thrombus in the fistula.

It is classified as one of the seronegative spondyloarthropathies and is known to have a poor correlation with cutaneous psoriasis. In fact, it often precedes the development of skin lesions. This condition affects both males and females equally, with around 10-20% of patients with skin lesions developing an arthropathy.

      The presentation of psoriatic arthropathy can vary, with different patterns of joint involvement. The most common type is symmetric polyarthritis, which is very similar to rheumatoid arthritis and affects around 30-40% of cases. Asymmetrical oligoarthritis is another type, which typically affects the hands and feet and accounts for 20-30% of cases. Sacroiliitis, DIP joint disease, and arthritis mutilans (severe deformity of fingers/hand) are other patterns of joint involvement. Other signs of psoriatic arthropathy include psoriatic skin lesions, periarticular disease, enthesitis, tenosynovitis, dactylitis, and nail changes.

      To diagnose psoriatic arthropathy, X-rays are often used. These can reveal erosive changes and new bone formation, as well as periostitis and a pencil-in-cup appearance. Management of this condition should be done by a rheumatologist, and treatment is similar to that of rheumatoid arthritis. However, there are some differences, such as the use of monoclonal antibodies like ustekinumab and secukinumab. Mild peripheral arthritis or mild axial disease may be treated with NSAIDs alone, rather than all patients being on disease-modifying therapy as with RA. Overall, psoriatic arthropathy has a better prognosis than RA.
