Question 1
Correct
-
A 29-year-old female patient visits her general practitioner complaining of muscle cramps and numbness in her hands and feet for the past 5 days. She also reports a tingling sensation around her mouth. The patient was diagnosed with epilepsy 8 weeks ago and has been prescribed phenytoin. What abnormality is most likely to be observed in her blood test results?
Your Answer: Corrected calcium of 1.5 mmol/L
Explanation:The patient is displaying typical symptoms of hypocalcaemia, including perioral paraesthesia, cramps, tetany, and convulsions. This condition can be a side effect of taking phenytoin, and if left untreated, it can lead to seizures due to changes in neuromuscular excitability. Mild cases of hypocalcaemia can be managed with oral supplementation, while more severe cases may require intravenous replacement.
It’s important to note that hypercalcaemia can cause bone pain, renal calculi, constipation, polyuria, fatigue, depression, and confusion. However, the patient does not display any of these symptoms.
Hyperkalaemia can cause muscle weakness and cardiac arrhythmias, but the patient does not have these symptoms. Hypokalaemia can also cause muscle weakness and cardiac arrhythmias, but the patient’s symptoms do not fit this condition.
Finally, hypernatraemia can cause nausea, vomiting, headache, and confusion, but the patient is not experiencing these symptoms.
Hypocalcaemia: Symptoms and Signs
Hypocalcaemia is a condition characterized by low levels of calcium in the blood. Since calcium is essential for proper muscle and nerve function, many of the symptoms and signs of hypocalcaemia are related to neuromuscular excitability. The most common features of hypocalcaemia include muscle twitching, cramping, and spasms, as well as perioral paraesthesia. In chronic cases, patients may experience depression and cataracts.
An electrocardiogram (ECG) may show a prolonged QT interval, while Trousseau’s sign may be present when the brachial artery is occluded by inflating the blood pressure cuff and maintaining pressure above systolic. This causes wrist flexion and fingers to be drawn together, and is seen in around 95% of patients with hypocalcaemia and around 1% of normocalcaemic people. Chvostek’s sign, which is seen in around 70% of patients with hypocalcaemia and around 10% of normocalcaemic people, involves tapping over the parotid gland to cause facial muscles to twitch.
In summary, hypocalcaemia can cause a range of symptoms and signs related to neuromuscular excitability, including muscle twitching, cramping, and spasms, as well as perioral paraesthesia, depression, and cataracts. Trousseau’s sign and Chvostek’s sign are also commonly observed in patients with hypocalcaemia.

A 76-year-old man, who lives alone, presents to his General Practitioner with an extensive itchy, red rash over the trunk, arms and legs, which has been worsening over the preceding three days. He has a past medical history of psoriasis, hypertension and high cholesterol.
On examination, he has an extensive erythematous rash covering much of his body, with evidence of scaling. He has a normal temperature, a blood pressure (BP) of 110/88 mmHg and a pulse of 101 beats per minute.
What is the most appropriate management for this patient, given the likely diagnosis?Your Answer: Admit to hospital
Explanation:Management of Erythroderma in an Elderly Patient Living Alone
Erythroderma is a dermatological emergency that requires urgent treatment. In elderly patients who are frail and live alone, hospital admission is necessary. This is the case for an 86-year-old man with a history of psoriasis who presents with erythroderma. Topical emollients and steroids are key in management, but this patient requires intravenous fluids and close monitoring for infection and dehydration. Oral antibiotics are not indicated unless there are signs of infection. A topical steroid with a vitamin D analogue may be appropriate for psoriasis, but urgent assessment by Dermatology in an inpatient setting is necessary. An outpatient appointment is not appropriate for this patient due to his age and living situation.

A 28-year-old woman returns from a holiday in Kenya with symptoms of foul-smelling loose stools, abdominal cramps and frequent flatulence. She has had the symptoms for five days when she presents to her General Practitioner for advice. A diagnosis of giardiasis is suspected.
What would be the most useful investigation to request for this patient?Your Answer: Send stool culture for microscopy and culture (MC+S)
Explanation:Diagnostic Tests for Giardiasis: Which Ones Are Necessary?
Giardiasis is a common parasitic infection that can cause gastrointestinal symptoms such as diarrhoea, abdominal pain, and bloating. If a patient presents with these symptoms and has a history of recent foreign travel, giardiasis should be considered as a possible cause. Here are some diagnostic tests that may be ordered to confirm the diagnosis:
Stool Culture for Microscopy and Culture (MC+S)
This test is specific for detecting giardia and other potential parasitic causes of gastrointestinal symptoms. It involves sending three stool specimens 2-3 days apart to a laboratory for analysis.Colonoscopy
A colonoscopy is not necessary to diagnose giardiasis, as the patient’s symptoms and travel history are usually sufficient to suggest the diagnosis. A stool culture is a more appropriate test.Duodenal Biopsy
A duodenal biopsy is not necessary to diagnose giardiasis, as it is an invasive test that is typically reserved for investigating malabsorption, iron-deficiency anaemia, or neoplasia.Full Blood Count
A full blood count is not useful for diagnosing giardiasis, as it typically does not cause peripheral leukocytosis or eosinophilia.In summary, a stool culture for MC+S is the most appropriate test for diagnosing giardiasis in a patient with gastrointestinal symptoms and a history of recent foreign travel. Other tests, such as colonoscopy, duodenal biopsy, and full blood count, are not necessary for making the diagnosis.

A 63-year-old woman presents to her General Practitioner concerned about a lesion to her right temple. It has been there for several months. Examination reveals a round lesion, 1 cm in diameter, with rolled edges and a pearly appearance.
Which of the following, from the history, is the most likely diagnosis?
Select the SINGLE most likely diagnosis from the list below. Select ONE option only.Your Answer: Basal cell carcinoma (BCC)
Explanation:Skin cancer can take on different forms, including basal cell carcinoma (BCC), actinic keratosis, herpes zoster infection, melanoma, and squamous cell carcinoma (SCC). BCCs can appear on any part of the body and often produce a bloody crust. AKs are scaly or hyperkeratotic lesions that can become malignant and are common in individuals over 60 years old. Herpes zoster infection causes a rash that is usually unilateral and follows a dermatomal distribution. Melanoma is a malignant tumour that arises from cutaneous melanocytes and can take on different types. SCC is the second most common type of skin cancer and arises from the keratinocytes of the epidermis. It predominantly affects sun-exposed sites and has a firm, indurated appearance with surrounding inflammation. BCCs are commonly found in sun-exposed areas and have a pearly appearance with rolled edges and surrounding telangiectasia. Management for skin cancer varies depending on the type and severity, but removal through curettage or excision is common for BCCs.

A 28-year-old male comes to the Emergency Department complaining of a severely painful, reddened right-eye that has been bothering him for the past 6 hours. He reports experiencing reduced visual acuity and seeing halos around light. The patient has a history of hypermetropia. Upon examination, the right-eye appears red with a fixed and dilated pupil and conjunctival injection. What is the most probable diagnosis?
Your Answer: Acute closed-angle glaucoma
Explanation:The correct diagnosis is acute closed-angle glaucoma, which is characterized by an increase in intra-ocular pressure due to impaired aqueous outflow. Symptoms include a painful red eye, reduced visual acuity, and haloes around light. Risk factors include hypermetropia, pupillary dilatation, and age-related lens growth. Examination findings typically include a fixed dilated pupil with conjunctival injection. Treatment options include reducing aqueous secretions with acetazolamide and increasing pupillary constriction with topical pilocarpine.
Anterior uveitis is an incorrect diagnosis, as it refers to inflammation of the anterior portion of the uvea and is associated with systemic inflammatory conditions. A key ophthalmoscopy finding is an irregular pupil.
Central retinal vein occlusion is also an incorrect diagnosis, as it causes acute blindness due to thromboembolism or vasculitis in the central retinal vein. Severe retinal haemorrhages are seen on ophthalmoscopy.
Infective conjunctivitis is another incorrect diagnosis, as it is characterized by sore, red eyes with discharge. Bacterial causes typically result in purulent discharge, while viral cases often have serous discharge.
Glaucoma is a group of disorders that cause optic neuropathy due to increased intraocular pressure (IOP). However, not all patients with raised IOP have glaucoma, and vice versa. Acute angle-closure glaucoma (AACG) is a type of glaucoma where there is a rise in IOP due to impaired aqueous outflow. Factors that increase the risk of AACG include hypermetropia, pupillary dilatation, and lens growth associated with age. Symptoms of AACG include severe pain, decreased visual acuity, haloes around lights, and a hard, red-eye. Management of AACG is an emergency and requires urgent referral to an ophthalmologist. Emergency medical treatment is necessary to lower the IOP, followed by definitive surgical treatment once the acute attack has subsided.
There are no specific guidelines for the initial medical treatment of AACG, but a combination of eye drops may be used, including a direct parasympathomimetic, a beta-blocker, and an alpha-2 agonist. Intravenous acetazolamide may also be administered to reduce aqueous secretions. Definitive management of AACG involves laser peripheral iridotomy, which creates a small hole in the peripheral iris to allow aqueous humour to flow to the angle. It is important to seek medical attention immediately if symptoms of AACG are present to prevent permanent vision loss.

A 21-year-old woman presents with a rash on her trunk that developed a few weeks after a sore throat. On examination, small, drop-shaped, salmon-pink plaques are observed. What is the most probable cause of this rash?
Your Answer: Guttate psoriasis
Explanation:Understanding Different Skin Conditions: Guttate Psoriasis, Dermatitis, Hand, Foot and Mouth Disease, Pityriasis Rosea, and Pustular Psoriasis
Skin conditions can be uncomfortable and sometimes even painful. Here are some common skin conditions and their characteristics:
Guttate psoriasis is a type of psoriasis that causes small, drop-shaped plaques on the chest, arms, legs, and scalp. It is usually caused by a streptococcal infection and can last for up to three months. Topical agents, such as steroids or calcipotriol, can be used to treat it.
Dermatitis, also known as eczema, results in rough patches of skin that are dry and itchy, particularly with exposure to irritants. In children and adults with long-standing disease, eczema is often localised to the flexure of the limbs.
Hand, foot and mouth disease (HFMD) is an acute viral illness characterised by vesicular eruptions in the mouth and papulovesicular lesions of the distal limbs. It should not be confused with foot and mouth disease of animals, which is caused by a different virus.
Pityriasis rosea is a skin rash that is characterised by distinctive, scaly, erythematous lesions. It is thought to be a reaction to exposure to infection.
Pustular psoriasis is a rarer type of psoriasis that causes pus-filled blisters (pustules) to appear on your skin. Different types of pustular psoriasis affect different parts of the body.
It is important to consult a healthcare professional for proper diagnosis and treatment of any skin condition.

A 19-year-old long-distance runner who is currently preparing for a regional marathon seeks an appointment with the team doctor due to an unusual sensation in her legs. She reports feeling numbness below her knee. During the examination, the doctor observes sensory loss below the left knee in a non-dermatomal distribution. The team doctor suspects a non-organic cause of her symptoms. What type of disorder is this an example of?
Your Answer: Somatisation disorder
Correct Answer: Conversion disorder
Explanation:Conversion disorder is a condition that often results in the loss of motor or sensory function and is believed to be triggered by stress.
Psychiatric Terms for Unexplained Symptoms
There are various psychiatric terms used to describe patients who exhibit symptoms for which no organic cause can be found. One such disorder is somatisation disorder, which involves the presence of multiple physical symptoms for at least two years, and the patient’s refusal to accept reassurance or negative test results. Another disorder is illness anxiety disorder, which is characterized by a persistent belief in the presence of an underlying serious disease, such as cancer, despite negative test results.
Conversion disorder is another condition that involves the loss of motor or sensory function, and the patient does not consciously feign the symptoms or seek material gain. Patients with this disorder may be indifferent to their apparent disorder, a phenomenon known as la belle indifference. Dissociative disorder, on the other hand, involves the process of ‘separating off’ certain memories from normal consciousness, and may manifest as amnesia, fugue, or stupor. Dissociative identity disorder (DID) is the most severe form of dissociative disorder and was previously known as multiple personality disorder.
Factitious disorder, also known as Munchausen’s syndrome, involves the intentional production of physical or psychological symptoms. Finally, malingering is the fraudulent simulation or exaggeration of symptoms with the intention of financial or other gain. Understanding these psychiatric terms can help healthcare professionals better diagnose and treat patients with unexplained symptoms.

Which of the following types of rash is commonly observed in the initial stages of Lyme disease?
Your Answer: Erythema marginatum
Correct Answer: Erythema chronicum migrans
Explanation:Understanding Lyme Disease
Lyme disease is a bacterial infection caused by Borrelia burgdorferi and is transmitted through tick bites. The early symptoms of Lyme disease include erythema migrans, a characteristic bulls-eye rash that appears at the site of the tick bite. This rash is painless, slowly increases in size, and can be more than 5 cm in diameter. Other early symptoms include headache, lethargy, fever, and joint pain.
If erythema migrans is present, Lyme disease can be diagnosed clinically, and antibiotics should be started immediately. The first-line test for Lyme disease is an enzyme-linked immunosorbent assay (ELISA) to detect antibodies to Borrelia burgdorferi. If the ELISA is negative but Lyme disease is still suspected, it should be repeated 4-6 weeks later. If Lyme disease is suspected in patients who have had symptoms for 12 weeks or more, an immunoblot test should be done.
Tick bites can cause significant anxiety, but routine antibiotic treatment is not recommended by NICE. If the tick is still present, it should be removed using fine-tipped tweezers, and the area should be washed. In cases of suspected or confirmed Lyme disease, doxycycline is the preferred treatment for early disease, while ceftriaxone is used for disseminated disease. A Jarisch-Herxheimer reaction may occur after initiating therapy, which can cause fever, rash, and tachycardia.
In summary, Lyme disease is a bacterial infection transmitted through tick bites. Early symptoms include erythema migrans, headache, lethargy, fever, and joint pain. Diagnosis is made through clinical presentation and ELISA testing, and treatment involves antibiotics. Tick bites do not require routine antibiotic treatment, and ticks should be removed using fine-tipped tweezers.

Which of the following outcomes confirms a diagnosis of diabetes mellitus?
Your Answer: Symptomatic patient with random glucose 12.0 mmol/L on one occasion
Explanation:To diagnose diabetes mellitus, fasting blood glucose levels should be above 7.0 or random blood glucose levels should be above 11.1. If the patient is asymptomatic, two readings are required for confirmation.
Type 2 diabetes mellitus can be diagnosed through a plasma glucose or HbA1c sample. The diagnostic criteria vary depending on whether the patient is experiencing symptoms or not. If the patient is symptomatic, a fasting glucose level of 7.0 mmol/l or higher or a random glucose level of 11.1 mmol/l or higher (or after a 75g oral glucose tolerance test) indicates diabetes. If the patient is asymptomatic, the same criteria apply but must be demonstrated on two separate occasions.
In 2011, the World Health Organization released supplementary guidance on the use of HbA1c for diagnosing diabetes. A HbA1c level of 48 mmol/mol (6.5%) or higher is diagnostic of diabetes mellitus. However, a HbA1c value of less than 48 mmol/mol (6.5%) does not exclude diabetes and may not be as sensitive as fasting samples for detecting diabetes. For patients without symptoms, the test must be repeated to confirm the diagnosis. It is important to note that increased red cell turnover can cause misleading HbA1c results.
There are certain conditions where HbA1c cannot be used for diagnosis, such as haemoglobinopathies, haemolytic anaemia, untreated iron deficiency anaemia, suspected gestational diabetes, children, HIV, chronic kidney disease, and people taking medication that may cause hyperglycaemia (such as corticosteroids).
Impaired fasting glucose (IFG) is defined as a fasting glucose level of 6.1 mmol/l or higher but less than 7.0 mmol/l. Impaired glucose tolerance (IGT) is defined as a fasting plasma glucose level less than 7.0 mmol/l and an OGTT 2-hour value of 7.8 mmol/l or higher but less than 11.1 mmol/l. People with IFG should be offered an oral glucose tolerance test to rule out a diagnosis of diabetes. A result below 11.1 mmol/l but above 7.8 mmol/l indicates that the person does not have diabetes but does have IGT.

Which one of the following statements regarding allergy testing is inaccurate?
Your Answer: Skin prick testing should be read after 48 hours
Explanation:The results of skin prick testing can be interpreted after 15-20 minutes, while skin patch testing requires 48 hours after the patch is removed to be read.
Types of Allergy Tests
Allergy tests are used to determine if a person has an allergic reaction to a particular substance. There are several types of allergy tests available, each with its own advantages and limitations. The most commonly used test is the skin prick test, which is easy to perform and inexpensive. Drops of diluted allergen are placed on the skin, and a needle is used to pierce the skin. A wheal will typically develop if a patient has an allergy. This test is useful for food allergies and pollen.
Another type of allergy test is the radioallergosorbent test (RAST), which determines the amount of IgE that reacts specifically with suspected or known allergens. Results are given in grades from 0 (negative) to 6 (strongly positive). This test is useful for food allergies, inhaled allergens (e.g. pollen), and wasp/bee venom.
Skin patch testing is useful for contact dermatitis. Around 30-40 allergens are placed on the back, and irritants may also be tested for. The patches are removed 48 hours later, and the results are read by a dermatologist after a further 48 hours. Blood tests may be used when skin prick tests are not suitable, for example if there is extensive eczema or if the patient is taking antihistamines. Overall, allergy tests are an important tool in diagnosing and managing allergies.

A 32-year-old woman presents to her General Practitioner complaining of occasional abdominal distension and bloating, which varies with her menstrual cycle and is accompanied by episodes of constipation. She works as a teacher and finds work stressful; she has previously taken a course of sertraline for depression/anxiety. On examination, bloods and colonoscopy are normal.
Which of the following is the most probable diagnosis?Your Answer: Irritable bowel syndrome (IBS)
Explanation:Irritable bowel syndrome (IBS) is a gastrointestinal disorder that causes abdominal pain, bloating, and changes in bowel habits without any identifiable organic pathology. It is more common in women and can be worsened by stress and the perimenstrual period. Diagnosis is made by ruling out other potential causes of symptoms. Management includes dietary changes, such as increasing fiber intake and avoiding trigger foods, as well as psychological support. Medications may also be used to alleviate symptoms. This patient’s symptoms are not consistent with chronic pancreatitis, ulcerative colitis, peptic ulcer disease, or diverticulitis.

An 80-year-old man comes in for a routine check-up with his General Practitioner. He has a medical history of atrial fibrillation, type II diabetes, depression, and chronic alcohol abuse. His current medications include warfarin 3 mg once daily, ramipril 2.5 mg once daily, bisoprolol 2 mg once daily, erythromycin 500 mg four times daily (day five of a 7-day course for cellulitis on the leg), and sertraline 50 mg once daily (started four weeks ago). He is allergic to penicillin. His blood work shows an INR of 6.5 (target 2.0-3.0). What is the most likely reason for his elevated INR?
Your Answer: Erythromycin is a P450 inhibiter
Explanation:The patient is taking erythromycin for cellulitis, which inhibits the cytochrome P450 enzymes responsible for breaking down drugs like warfarin and statins. As a result, the effects of warfarin are potentiated, leading to a higher than expected INR. Bisoprolol is unlikely to have contributed to the change in INR as it does not affect the P450 system. Chronic alcohol abuse can induce P450 enzymes, but this would cause a lower INR. Erythromycin is an inhibitor, not an inducer, of P450 enzymes. Sertraline, though recently started, is also an enzyme inhibitor and cannot explain the high INR.

A 32-year-old woman presents with back pain that shoots down her right leg, which she experienced suddenly while picking up her child. During examination, she can only raise her right leg to 30 degrees due to shooting pains down her leg. There is reduced sensation on the dorsum of her right foot, especially around the big toe, and weak foot dorsiflexion. The ankle and knee reflexes seem intact, and a diagnosis of disc prolapse is suspected. Which nerve root is most likely affected?
Your Answer: L5
Explanation:The characteristics of a L5 lesion include the absence of dorsiflexion in the foot and a lack of sensation on the top of the foot.
Understanding Prolapsed Disc and its Features
A prolapsed lumbar disc is a common cause of lower back pain that can lead to neurological deficits. It is characterized by clear dermatomal leg pain, which is usually worse than the back pain. The pain is often aggravated when sitting. The features of the prolapsed disc depend on the site of compression. For instance, L3 nerve root compression can cause sensory loss over the anterior thigh, weak quadriceps, reduced knee reflex, and a positive femoral stretch test. On the other hand, L4 nerve root compression can lead to sensory loss in the anterior aspect of the knee, weak quadriceps, reduced knee reflex, and a positive femoral stretch test.
The management of prolapsed disc is similar to that of other musculoskeletal lower back pain. It involves analgesia, physiotherapy, and exercises. According to NICE, the first-line treatment for back pain without sciatica symptoms is NSAIDs +/- proton pump inhibitors, rather than neuropathic analgesia. If the symptoms persist after 4-6 weeks, referral for consideration of MRI is appropriate. Understanding the features of prolapsed disc can help in the diagnosis and management of this condition.

A 52-year-old Caucasian man presents with blood pressure readings of 150/100 mmHg, 148/95mmHg and 160/95mmHg during three consecutive visits to his GP surgery. He refuses ambulatory blood pressure monitoring due to its interference with his job as a construction worker. His home blood pressure readings are consistently above 150/95mmHg. What is the most appropriate initial approach to manage his condition?
Your Answer: Ramipril
Explanation:For a newly diagnosed patient with hypertension who is under 55 years old and has stage 2 hypertension, it is recommended to add either an ACE inhibitor or an angiotensin receptor blocker. This is in accordance with the NICE guidelines, which suggest that antihypertensive drug treatments should be offered to individuals of any age with stage 2 hypertension. If the patient is 55 years or older, a calcium channel blocker like amlodipine is recommended instead.
NICE Guidelines for Managing Hypertension
Hypertension, or high blood pressure, is a common condition that can lead to serious health problems if left untreated. The National Institute for Health and Care Excellence (NICE) has published updated guidelines for the management of hypertension in 2019. Some of the key changes include lowering the threshold for treating stage 1 hypertension in patients under 80 years old, allowing the use of angiotensin receptor blockers instead of ACE inhibitors, and recommending the use of a calcium channel blocker or thiazide-like diuretic in addition to an ACE inhibitor or angiotensin receptor blocker.
The guidelines also provide a flow chart for the diagnosis and management of hypertension. Lifestyle advice, such as reducing salt intake, caffeine intake, and alcohol consumption, as well as exercising more and losing weight, should not be forgotten and is frequently tested in exams. Treatment options depend on the patient’s age, ethnicity, and other factors, and may involve a combination of drugs.
NICE recommends treating stage 1 hypertension in patients under 80 years old if they have target organ damage, established cardiovascular disease, renal disease, diabetes, or a 10-year cardiovascular risk equivalent to 10% or greater. For patients with stage 2 hypertension, drug treatment should be offered regardless of age. The guidelines also provide step-by-step treatment options, including adding a third or fourth drug if necessary.
New drugs, such as direct renin inhibitors like Aliskiren, may have a role in patients who are intolerant of more established antihypertensive drugs. However, trials have only investigated the fall in blood pressure and no mortality data is available yet. Patients who fail to respond to step 4 measures should be referred to a specialist. The guidelines also provide blood pressure targets for different age groups.

A 50-year-old woman with type 1 diabetes mellitus is seen in the diabetes clinic. Her blood tests from three months ago showed:
K+ 4.5 mmol/l
Creatinine 116 µmol/l
eGFR 47 ml/min
She was started on lisinopril to manage hypertension and protect her kidneys. The medication was titrated up to the treatment dose. Her current blood results are:
K+ 4.9 mmol/l
Creatinine 123 µmol/l
eGFR 44 ml/min
What is the most appropriate action to take in this situation?Your Answer: No action
Explanation:The slight alterations in creatinine and eGFR are within acceptable limits and do not warrant discontinuation of ACE inhibitors.
Hypertension Management in Chronic Kidney Disease
Chronic kidney disease (CKD) patients often require more than two drugs to manage hypertension. The first-line treatment is ACE inhibitors, which are particularly effective in proteinuric renal disease such as diabetic nephropathy. However, these drugs may cause a small decrease in glomerular filtration pressure (GFR) and a rise in creatinine. According to NICE guidelines, a decrease in eGFR of up to 25% or a rise in creatinine of up to 30% is acceptable, but any increase should prompt careful monitoring and exclusion of other causes such as NSAIDs. A rise greater than this may indicate underlying renovascular disease.
Furosemide is a useful antihypertensive drug in CKD patients, especially when the GFR falls below 45 ml/min. It also helps to lower serum potassium levels. However, high doses are usually required, and if the patient becomes dehydrated due to conditions such as gastroenteritis, the drug should be temporarily stopped. The NKF K/DOQI guidelines suggest a lower cut-off of less than 30 ml/min. Overall, hypertension management in CKD patients requires careful monitoring and individualized treatment plans.

A 55-year-old woman presents to her GP complaining of persistent coloured sputum for the past 2 years. She has a history of frequent chest infections. On examination, bilateral basal crepitations were heard.
Which of the following is the most probable diagnosis?
Your Answer: Bronchiectasis
Explanation:Differentiating Bronchiectasis from Other Respiratory Conditions
Bronchiectasis is a condition characterized by permanent dilatation of the bronchi and bronchioles due to chronic infection. Patients with bronchiectasis typically present with a persistent cough, copious purulent sputum, and occasional haemoptysis. Bilateral crackles are often found during examination. It is important to differentiate bronchiectasis from other respiratory conditions such as COPD, aspergilloma, extrinsic allergic alveolitis, and idiopathic pulmonary fibrosis. While patients with COPD may have sputum production and chronic dyspnoea, they are likely to have quiet breath sounds or wheeze. Aspergilloma, on the other hand, is usually asymptomatic with little sputum production, but may cause cough, haemoptysis, lethargy, and weight loss. Extrinsic allergic alveolitis results from a hypersensitivity reaction to fungal spores or avian proteins, causing a dry, non-productive cough. Idiopathic pulmonary fibrosis, which causes a dry cough, exertional dyspnoea, weight loss, and arthralgia, is also different from bronchiectasis. Therefore, a thorough evaluation of symptoms and examination is necessary to accurately diagnose bronchiectasis and differentiate it from other respiratory conditions.

A 68-year-old woman visits her GP complaining of urinary frequency and dysuria that has been present for 2 days. Upon urine dip, she tests positive for blood, leucocytes, nitrites, and protein. Her medical history includes rheumatoid arthritis treated with methotrexate and hypertension treated with ramipril. She has no known allergies. The patient is worried because she has been cautioned about an antibiotic that she should avoid due to her current medications.
What medication has she been warned about from the list provided?Your Answer: Trimethoprim
Explanation:Understanding Trimethoprim: Mechanism of Action, Adverse Effects, and Use in Pregnancy
Trimethoprim is an antibiotic that is commonly used to treat urinary tract infections. Its mechanism of action involves interfering with DNA synthesis by inhibiting dihydrofolate reductase. This can potentially interact with methotrexate, which also inhibits dihydrofolate reductase. However, the use of trimethoprim can also lead to adverse effects such as myelosuppression and a transient rise in creatinine. The drug can competitively inhibit the tubular secretion of creatinine, resulting in a temporary increase that reverses upon stopping the drug. Additionally, trimethoprim can block the ENaC channel in the distal nephron, causing a hyperkalaemic distal RTA (type 4). It can also inhibit creatinine secretion, often leading to an increase in creatinine by around 40 points, but not necessarily causing AKI.
When it comes to the use of trimethoprim in pregnancy, caution is advised. The British National Formulary (BNF) warns of a teratogenic risk in the first trimester due to its folate antagonist properties. As such, manufacturers advise avoiding the use of trimethoprim during pregnancy. It is important to understand the potential risks and benefits of using this antibiotic and to consult with a healthcare provider before taking any medication.

Hypothyroidism, adrenal insufficiency, Cushing syndrome, primary hypoparathyroidism, and secondary hypoparathyroidism are all endocrine disorders that can present with various symptoms. Hypothyroidism may cause cerebellar ataxia, myxoedema, and congestive cardiac failure, and is treated with replacement of thyroid hormone. Adrenal insufficiency may cause tiredness, weakness, and postural hypotension, among other symptoms. Cushing syndrome may present with central obesity, skin and muscle atrophy, and osteoporosis. Primary hypoparathyroidism may cause hypocalcaemia symptoms, while secondary hypoparathyroidism may also present with hypocalcaemia symptoms. Treatment options vary depending on the specific disorder.

A 26-year-old man complains of rectal bleeding and a sharp, stinging pain during bowel movements. He has been experiencing these symptoms for the past two weeks. The patient reports a history of constipation and notes fresh blood on the toilet paper when wiping. Although rectal examination is challenging due to pain, no external abnormalities are observed. What is the probable diagnosis?
Your Answer: Anal fissure
Explanation:Anal fissures are typically identified by the presence of both pain and bleeding. While thrombosed external hemorrhoids can also cause pain, internal hemorrhoids usually do not. It can be challenging to detect superficial anal fissures during an examination.
Understanding Anal Fissures: Causes, Symptoms, and Treatment
Anal fissures are tears in the lining of the distal anal canal that can be either acute or chronic. Acute fissures last for less than six weeks, while chronic fissures persist for more than six weeks. The most common risk factors for anal fissures include constipation, inflammatory bowel disease, and sexually transmitted infections such as HIV, syphilis, and herpes.
Symptoms of anal fissures include painful, bright red rectal bleeding, with around 90% of fissures occurring on the posterior midline. If fissures are found in other locations, underlying causes such as Crohn’s disease should be considered.
Management of acute anal fissures involves softening stool, dietary advice, bulk-forming laxatives, lubricants, topical anaesthetics, and analgesia. For chronic anal fissures, the same techniques should be continued, and topical glyceryl trinitrate (GTN) is the first-line treatment. If GTN is not effective after eight weeks, surgery (sphincterotomy) or botulinum toxin may be considered, and referral to secondary care is recommended.
In summary, anal fissures can be a painful and uncomfortable condition, but with proper management, they can be effectively treated. It is important to identify and address underlying risk factors to prevent the development of chronic fissures.

A 3-day old baby boy was delivered vaginally at full term after two cycles of In vitro fertilization (IVF). All antenatal scans were normal. Initially, he was feeding well, but over the past 24 hours, he has been feeding poorly, and his tummy has become larger. He has not had a bowel movement yet, and his mother has noticed multiple green/yellow vomits in the last few hours. There is no projectile vomiting. What is the probable diagnosis?
Your Answer: Pyloric stenosis
Correct Answer: Meconium ileus
Explanation:The correct answer is meconium ileus, as the baby is showing signs of abdominal distension and bilious vomiting within the first 24-48 hours of life, and has not passed any meconium. While meconium ileus is more common in children with cystic fibrosis, the baby is too young to have been diagnosed with this condition yet, as the heel prick test is normally done at day 5.
Duodenal atresia is less likely, as it typically presents in the first few hours of life and is often detected on antenatal scans, which were normal in this case.
Necrotizing enterocolitis is unlikely, as it typically affects preterm babies at a few weeks of life, whereas this baby was born at term and is only 2 days old.
Posseting, which is the act of bringing up small quantities of milk without pain or discomfort, is not associated with any pathology. However, in this scenario, the baby is vomiting green/yellow fluid, which is not typical of posseting. Therefore, posseting is an incorrect answer.
Causes and Treatments for Bilious Vomiting in Neonates
Bilious vomiting in neonates can be caused by various disorders, including duodenal atresia, malrotation with volvulus, jejunal/ileal atresia, meconium ileus, and necrotising enterocolitis. Duodenal atresia occurs in 1 in 5000 births and is more common in babies with Down syndrome. It typically presents a few hours after birth and can be diagnosed through an abdominal X-ray that shows a double bubble sign. Treatment involves duodenoduodenostomy. Malrotation with volvulus is usually caused by incomplete rotation during embryogenesis and presents between 3-7 days after birth. An upper GI contrast study or ultrasound can confirm the diagnosis, and treatment involves Ladd’s procedure. Jejunal/ileal atresia is caused by vascular insufficiency in utero and occurs in 1 in 3000 births. It presents within 24 hours of birth and can be diagnosed through an abdominal X-ray that shows air-fluid levels. Treatment involves laparotomy with primary resection and anastomosis. Meconium ileus occurs in 15-20% of babies with cystic fibrosis and presents in the first 24-48 hours of life with abdominal distension and bilious vomiting. Diagnosis involves an abdominal X-ray that shows air-fluid levels, and a sweat test can confirm cystic fibrosis. Treatment involves surgical decompression, and segmental resection may be necessary for serosal damage. Necrotising enterocolitis occurs in up to 2.4 per 1000 births, with increased risks in prematurity and inter-current illness. It typically presents in the second week of life and can be diagnosed through an abdominal X-ray that shows dilated bowel loops, pneumatosis, and portal venous air. Treatment involves conservative and supportive measures for non-perforated cases, while laparotomy and resection are necessary for perforated cases or ongoing clinical deterioration.

Among the following individuals, which one has the highest risk of suicide?
Your Answer: A 50-year-old man with alcohol dependence and prior suicide attempts
Explanation:Understanding the Risk Factors for Suicide
Suicide is a complex issue with a variety of risk factors. The strongest indicators of suicide are the presence of a mental disorder, including alcohol-use disorder, and a history of previous suicide attempts. Age and sex also play a role, with the risk increasing with age and men being more likely to complete suicide. Marital status, unemployment, living alone, and chronic illnesses are also associated with an increased risk. It is important to understand these risk factors in order to identify and prevent suicide.

A 43-year-old man visits his GP complaining of a painful right shoulder. Despite being generally healthy and playing tennis regularly, he has been limited by the pain. Upon examination, his shoulders appear symmetrical with no skin changes, but he experiences mild tenderness over the right acromion. He can fully abduct his arm, but experiences pain approximately halfway through the motion, with the start and end of abduction being pain-free. There are no other symptoms or abnormalities in his upper limbs. What is the probable underlying pathology for this man's presentation?
Your Answer: Subacromial impingement
Explanation:Subacromial impingement is often characterized by a painful arc of abduction. This is likely the cause of the patient’s shoulder pain, which is accompanied by tenderness at the acromion and pain around the midpoint of abduction (typically between 60 to 120 degrees). These symptoms are not indicative of inflammatory arthritis affecting the acromioclavicular joint, which is rare. Osteoarthritis affecting the ACJ may cause tenderness and swelling, but not acromial tenderness or a painful arc in abduction. Cervical radiculopathy would cause neuropathic pain in the distribution of a cervical root, which is not consistent with the patient’s symptoms. Rheumatoid arthritis and other inflammatory arthropathies typically cause acute joint inflammation and effusion, which is not present in this case. A supraspinatus tear is a possible differential diagnosis, but the pain would be limited to the initial 60 degrees of abduction rather than the midpoint, indicating impingement as the more likely cause. Depending on the extent of the tear, abduction may also be limited due to difficulty initiating the movement.
Understanding Rotator Cuff Injuries
Rotator cuff injuries are a common cause of shoulder problems that can be classified into four types of disease: subacromial impingement, calcific tendonitis, rotator cuff tears, and rotator cuff arthropathy. The symptoms of a rotator cuff injury include shoulder pain that worsens during abduction.
The signs of a rotator cuff injury include a painful arc of abduction, which typically occurs between 60 and 120 degrees in cases of subacromial impingement. In cases of rotator cuff tears, the pain may be felt in the first 60 degrees of abduction. Additionally, tenderness over the anterior acromion may be present.

A woman in her early thirties visits your GP clinic with a plan to conceive a baby in a year's time. She has barrister exams scheduled for this year and prefers not to get pregnant before that. However, she desires to conceive soon after her exams. Which contraceptive method is commonly linked with a prolonged delay in fertility restoration?
Your Answer: Combined oral contraceptive pill
Correct Answer: Depo-Provera
Explanation:Condoms act as a barrier contraceptive and do not have any impact on ovulation, therefore they do not cause any delay in fertility. The intrauterine system (IUS) functions by thickening cervical mucous and may prevent ovulation in some women, but most women still ovulate. Once the IUS is removed, most women regain their fertility immediately.
The combined oral contraceptive pill may postpone the return to a normal menstrual cycle in some women, but the majority of them can conceive within a month of discontinuing it. The progesterone-only pill is less likely to delay the return to a normal cycle as it does not contain oestrogen.
Depo-Provera can last up to 12 weeks, and it may take several months for the body to return to a normal menstrual cycle, which can delay fertility. As a result, it is not the most suitable method for a woman who wants to resume ovulatory cycles immediately.
Injectable Contraceptives: Depo Provera
Injectable contraceptives are a popular form of birth control in the UK, with Depo Provera being the main option available. This contraceptive contains 150mg of medroxyprogesterone acetate and is administered via intramuscular injection every 12 weeks. It can be given up to 14 weeks after the last dose without the need for extra precautions. The primary method of action is by inhibiting ovulation, while secondary effects include cervical mucus thickening and endometrial thinning.
However, there are some disadvantages to using Depo Provera. Once the injection is given, it cannot be reversed, and there may be a delayed return to fertility of up to 12 months. Adverse effects may include irregular bleeding and weight gain, and there is a potential increased risk of osteoporosis. It should only be used in adolescents if no other method of contraception is suitable.
It is important to note that there are contraindications to using Depo Provera, such as current breast cancer (UKMEC 4) or past breast cancer (UKMEC 3). While Noristerat is another injectable contraceptive licensed in the UK, it is rarely used in clinical practice and is given every 8 weeks. Overall, injectable contraceptives can be an effective form of birth control, but it is important to weigh the potential risks and benefits before deciding on this method.

A 70-year-old man presents with central chest pain that has been ongoing for 2 hours. The pain is radiating to his left arm. He has a medical history of hypertension and hypercholesterolemia.
Upon examination, the patient appears uncomfortable and sweaty. His vital signs are as follows:
- Heart rate: 90 bpm
- Respiratory rate: 20 breaths/min
- Peripheral oxygen saturation: 95% on room air
- Blood pressure: 136/78 mmHg
- Temperature: 37.0ºC
An ECG performed by the paramedics shows ST depression in leads II, III, and aVF, as well as T-wave inversion.
What is the immediate treatment that should be given?Your Answer: Aspirin, nitrate, morphine, oxygen
Correct Answer: Aspirin, nitrate, morphine
Explanation:The appropriate combination in this scenario is aspirin, nitrate, and morphine. The addition of oxygen is not necessary and may even be inappropriate. Ramipril and bisoprolol are not recommended for acute treatment but may be used for long-term management of ACS. Therefore, aspirin, nitrate, and oxygen is an incorrect combination, and morphine should also be included due to the patient’s significant pain. Oxygen should not be administered as the patient’s oxygen saturation levels are already adequate.
Managing Acute Coronary Syndrome: A Summary of NICE Guidelines
Acute coronary syndrome (ACS) is a common and serious medical condition that requires prompt management. The management of ACS has evolved over the years, with the development of new drugs and procedures such as percutaneous coronary intervention (PCI). The National Institute for Health and Care Excellence (NICE) has updated its guidelines on the management of ACS in 2020.
ACS can be classified into three subtypes: ST-elevation myocardial infarction (STEMI), non ST-elevation myocardial infarction (NSTEMI), and unstable angina. The management of ACS depends on the subtype. However, there are common initial drug therapies for all patients with ACS, such as aspirin and nitrates. Oxygen should only be given if the patient has oxygen saturations below 94%, and morphine should only be given for severe pain.
For patients with STEMI, the first step is to assess eligibility for coronary reperfusion therapy, which can be either PCI or fibrinolysis. Patients with NSTEMI/unstable angina require a risk assessment using the Global Registry of Acute Coronary Events (GRACE) tool to determine whether they need coronary angiography (with follow-on PCI if necessary) or conservative management.
This summary provides an overview of the NICE guidelines for managing ACS. The guidelines are complex and depend on individual patient factors, so healthcare professionals should review the full guidelines for further details. Proper management of ACS can improve patient outcomes and reduce the risk of complications.

A 25-year-old homeless person is brought into the general practice surgery, having been found nearby in a disoriented state.
On examination, they have neck stiffness and a non-blanching rash on their arms. Their vital signs are stable except for fever and tachycardia. They score 13/15 on the Glasgow Coma Scale. An ambulance has been called to transfer them to the hospital.
Which of the following is the most appropriate action to perform while awaiting the ambulance?
Your Answer: Give an intravenous (IV) fluid bolus
Correct Answer: Administer a dose of parenteral benzylpenicillin
Explanation:Appropriate Actions for Suspected Bacterial Meningitis with Non-Blanching Rash
When a patient presents with suspected bacterial meningitis and a non-blanching rash, it is crucial to take appropriate actions promptly. Administering a single dose of parenteral benzylpenicillin at the earliest opportunity is recommended, but this should not delay the transfer to the hospital. It is also important to notify the regional Public Health consultant about the suspected case.
While administering paracetamol for fever and starting the patient on high-flow oxygen may be necessary in some cases, they would not take priority over the administration of parenteral benzylpenicillin. Additionally, an IV fluid bolus is not indicated unless the patient’s vital signs are unstable. By taking these appropriate actions, healthcare providers can help ensure the best possible outcome for patients with suspected bacterial meningitis and non-blanching rash.

A 67-year-old male experiences a cardiac arrest during coronary angiography in the catheter laboratory. His heart rate is 164 beats per minute and the 12-lead ECG monitor displays ventricular tachycardia. As you begin to assess him, you are unable to detect a pulse and immediately call for assistance.
What is the next appropriate step to take?Your Answer:
Correct Answer: Deliver a maximum of three successive shocks
Explanation:If a patient experiences cardiac arrest in VF/pulseless VT and is monitored, such as in a coronary care unit, critical care unit, or catheter laboratory, they should receive a maximum of three successive shocks instead of one shock followed by two minutes of CPR. After the shocks, chest compressions should be administered for two minutes. Once compressions restart, adrenaline 1mg IV and amiodarone 300 mg IV should be given for shockable rhythms (VT/pulseless VF). Adrenaline 1mg IV should be given after alternate shocks (every 3-5 minutes). For non-shockable rhythms (pulseless electrical activity/asystole), adrenaline 1mg IV should be given as soon as venous access is achieved and administered alongside CPR. Pulseless electrical activity is a type of cardiac arrest where there is electrical activity (other than ventricular tachycardia) that would normally have an associated pulse. Asystole is a complete cessation of any electrical and mechanical heart activity.
The 2015 Resus Council guidelines for adult advanced life support outline the steps to be taken when dealing with patients with shockable and non-shockable rhythms. For both types of patients, chest compressions are a crucial part of the process, with a ratio of 30 compressions to 2 ventilations. Defibrillation is recommended for shockable rhythms, with a single shock for VF/pulseless VT followed by 2 minutes of CPR. Adrenaline and amiodarone are the drugs of choice for non-shockable rhythms, with adrenaline given as soon as possible and amiodarone administered after 3 shocks for VF/pulseless VT. Thrombolytic drugs should be considered if a pulmonary embolus is suspected. Atropine is no longer recommended for routine use in asystole or PEA. Oxygen should be titrated to achieve saturations of 94-98% following successful resuscitation. The Hs and Ts should be considered as potential reversible causes of cardiac arrest.

A 25-year-old man presents to his General Practitioner with a 3-month history of diarrhoea and intermittent abdominal pain. He has also noticed blood mixed with his stools over the past week. He is referred to secondary care where he has a colonoscopy and is diagnosed with Crohn’s disease.
Which of the following medications would be used to induce remission in this patient with a first presentation of Crohn’s disease?
Select the SINGLE most appropriate management from the list below.Your Answer:
Correct Answer: Prednisolone
Explanation:Treatment Options for Crohn’s Disease
Crohn’s disease is a chronic inflammatory bowel disease that can cause a range of symptoms, including abdominal pain, diarrhea, and weight loss. There are several treatment options available for patients with Crohn’s disease, depending on the severity of their symptoms and the stage of their disease.
Prednisolone is a commonly used corticosteroid for patients with a first presentation of Crohn’s disease or a single inflammatory exacerbation within a 12-month period. Azathioprine may be added to glucocorticoid treatment to induce remission if there are more than two exacerbations in a 12-month period or difficulty in tapering the glucocorticoid dose. Infliximab is recommended for adults with severe active Crohn’s disease who have not responded to or are intolerant to conventional therapy.
Mesalazine, an aminosalicylate, may be used for a first presentation of Crohn’s disease if glucocorticoids are contraindicated or not tolerated. It may also be used in addition to oral steroid treatment. Methotrexate should not be used as a monotherapy to induce remission. Instead, corticosteroids are the first-line treatment for inducing remission in patients with a first presentation of Crohn’s disease. If an adjuvant treatment is required, azathioprine or mercaptopurine can be taken with the corticosteroid. If these medications cannot be tolerated, methotrexate may be added instead.
In summary, the treatment options for Crohn’s disease vary depending on the severity of the disease and the patient’s response to previous treatments. It is important for patients to work closely with their healthcare provider to determine the best course of treatment for their individual needs.

You assess a 27-year-old female patient with a medical history of asthma. She is currently taking salbutamol 100 mcg 2 puffs as needed. However, she stopped taking her beclometasone dipropionate 400 mcg twice daily and salmeterol 50 mcg twice daily inhalers last week after discovering her pregnancy. She was worried about the potential harm to her unborn child. What would be the most suitable course of action?
Your Answer:
Correct Answer: Reassure + restart beclometasone and salmeterol inhalers
Explanation:The management of asthma in adults has been updated by NICE in 2017, following the 2016 BTS guidelines. One of the significant changes is in ‘step 3’, where patients on a SABA + ICS whose asthma is not well controlled should be offered a leukotriene receptor antagonist instead of a LABA. NICE does not follow the stepwise approach of the previous BTS guidelines, but to make the guidelines easier to follow, we have added our own steps. The steps range from newly-diagnosed asthma to SABA +/- LTRA + one of the following options, including increasing ICS to high-dose, a trial of an additional drug, or seeking advice from a healthcare professional with expertise in asthma. Maintenance and reliever therapy (MART) is a form of combined ICS and LABA treatment that is only available for ICS and LABA combinations in which the LABA has a fast-acting component. It should be noted that NICE does not recommend changing treatment in patients who have well-controlled asthma simply to adhere to the latest guidance. The definitions of what constitutes a low, moderate, or high-dose ICS have also changed, with <= 400 micrograms budesonide or equivalent being a low dose, 400 micrograms - 800 micrograms budesonide or equivalent being a moderate dose, and > 800 micrograms budesonide or equivalent being a high dose for adults.

An 80-year-old woman is admitted with acute confusion caused by a urinary tract infection. Despite treatment with antibiotics, environmental changes, and reassurance, she continues to be agitated. You are contemplating prescribing haloperidol. What is one condition that may be significantly exacerbated by the use of haloperidol?
Your Answer:
Correct Answer: Parkinson's disease
Explanation:If possible, antipsychotics should be avoided as they can exacerbate Parkinson’s disease symptoms. Instead, a low dose of oral lorazepam may be considered as an alternative.
Acute confusional state, also known as delirium or acute organic brain syndrome, is a condition that affects up to 30% of elderly patients admitted to hospital. It is more common in patients over the age of 65, those with a background of dementia, significant injury, frailty or multimorbidity, and those taking multiple medications. The condition is often triggered by a combination of factors, such as infection, metabolic imbalances, change of environment, and underlying medical conditions.
The symptoms of acute confusional state can vary widely, but may include memory disturbances, agitation or withdrawal, disorientation, mood changes, visual hallucinations, disturbed sleep, and poor attention. Treatment involves identifying and addressing the underlying cause, modifying the patient’s environment, and using sedatives such as haloperidol or olanzapine. However, managing the condition can be challenging in patients with Parkinson’s disease, as antipsychotics can worsen Parkinsonian symptoms. In such cases, careful reduction of Parkinson medication may be helpful, and atypical antipsychotics such as quetiapine and clozapine may be preferred for urgent treatment.
Overall, acute confusional state is a complex condition that requires careful management and individualized treatment. By addressing the underlying causes and providing appropriate sedation, healthcare professionals can help patients recover from this condition and improve their overall quality of life.

A 35-year-old overweight man visits the clinic with concerns about abdominal discomfort he experienced over the weekend. He reports that the discomfort began in his upper abdomen shortly after eating a large pizza on Friday night. The discomfort then shifted to the left side of his abdomen. He also vomited a few times. Most of the symptoms subsided within 24 hours. During the examination, he is still slightly tender in the left upper quadrant and has no fever or jaundice.
What is the most probable diagnosis?Your Answer:
Correct Answer: Biliary colic
Explanation:Biliary colic is a common symptom of gallstones, occurring in 1-4% of patients with choledocholithiasis. The pain is intense and dull, usually resolving within 30-90 minutes, and often occurs after consuming fatty meals. This matches the patient’s symptoms and risk factors. If left untreated, biliary colic can progress to acute cholecystitis, which presents with upper abdominal pain, nausea, vomiting, and fever. However, since the patient’s symptoms resolved within 24 hours, acute cholecystitis is unlikely. Acute viral hepatitis is also an unlikely diagnosis, as the patient has no known exposure to the viruses and her symptoms resolved too quickly. Acute pancreatitis presents with severe abdominal pain, nausea, vomiting, and fever, which does not match the patient’s symptoms. Ascending cholangitis is also unlikely, as the patient is afebrile and not jaundiced, and her symptoms resolved within 24 hours.
