Question 1Principles of general practice and primary care

In the MICGP framework for Irish general practice, which consultation model is most associated with a patient-centred approach that explores the patient's ideas, concerns and expectations before negotiating a management plan?

  1. Neighbour model
  2. Stott and Davis model
  3. Byrne and Long model
  4. Pendleton model Correct answer.

Explanation

The Pendleton model is explicitly patient-centred and structures the consultation around the patient's ideas, concerns, expectations and feelings before agreeing on a shared management plan. It builds on the patient-centred clinical method and is widely taught in Irish general practice training. The other models focus on task categories, consultation phases or doctor behaviour rather than this specific patient-centred negotiation.

Question 2Principles of general practice and primary care

A GP registrar is told that general practice in Ireland is characterised by 'first contact, continuous, comprehensive and coordinated care'. Which feature best distinguishes primary care from secondary care in this framework?

  1. Access restricted to patients with chronic disease
  2. Longitudinal continuity with a known population Correct answer.
  3. Provision of care only during office hours
  4. Care delivered exclusively by hospital consultants

Explanation

The defining feature of primary care is longitudinal continuity with a registered or known population, alongside first-contact, comprehensive and coordinated care. This continuity allows the GP to build accumulated knowledge of the patient over time. The other options describe restrictions that do not define primary care.

Question 3Principles of general practice and primary care

A patient with type 2 diabetes attends for review. Under the Irish chronic disease management arrangements, which element is a core component of structured diabetes care in general practice?

  1. Systematic recording of HbA1c, blood pressure and renal function Correct answer.
  2. Annual retinal screening performed by the GP
  3. Routine referral to endocrinology for all patients
  4. Three-monthly hospital clinic review

Explanation

Structured diabetes care in general practice centres on systematic recording and review of key parameters such as HbA1c, blood pressure, renal function and foot examination, with recall systems. Retinal screening is delivered through the national diabetic retinopathy screening programme rather than by the GP. Routine endocrinology referral and three-monthly hospital review are not core requirements for all patients.

Question 4Principles of general practice and primary care

Which principle best describes the concept of 'opportunistic health promotion' in general practice?

  1. Using any consultation as an opening to address relevant preventive issues Correct answer.
  2. Referring all preventive work to public health nurses
  3. Restricting prevention to patients who request it
  4. Delivering a full health check to every patient at every visit

Explanation

Opportunistic health promotion uses the contact generated by any consultation as an opportunity to address relevant preventive issues, such as smoking or vaccination status. It is proportionate and relevant to the presenting problem rather than a full check at every visit. It does not depend on the patient requesting prevention.

Question 5Principles of general practice and primary care

A GP is considering the 'inverse care law' when planning services for a deprived urban area. Which statement best captures this principle?

  1. Preventive care is equally distributed across all groups
  2. Care quality is inversely proportional to the doctor's experience
  3. Patients with the greatest health needs tend to receive the least care Correct answer.
  4. Patients in affluent areas overuse services

Explanation

The inverse care law, described by Julian Tudor Hart, holds that the availability of good medical care tends to vary inversely with the need for it in the population served. Deprived populations often have the highest needs but the poorest access. The other statements misstate the principle.

Question 6Principles of general practice and primary care

During a consultation, a GP uses the 'safety netting' technique. Which action best illustrates this?

  1. Arranging a follow-up appointment only if the patient requests one
  2. Prescribing a broad-spectrum antibiotic
  3. Documenting the consultation in the electronic record
  4. Advising the patient when to seek help again if symptoms change or fail to resolve Correct answer.

Explanation

Safety netting involves giving the patient clear advice about what to do if symptoms do not resolve or worsen, and when to re-present. It provides a structured contingency plan that reduces diagnostic uncertainty risk. Documentation and prescribing are separate actions, and follow-up should not depend solely on patient request.

Question 7Principles of general practice and primary care

A GP practice wishes to audit its cervical smear uptake. Which sequence correctly describes the audit cycle?

  1. Set standards, refer non-attenders, discharge patients
  2. Define standards, collect data, compare with standards, implement change and re-audit Correct answer.
  3. Implement change, define standards, collect data, re-audit
  4. Collect data, publish results, close the project

Explanation

Clinical audit follows a cycle of defining standards, collecting data, comparing performance against those standards, implementing change and then re-auditing to confirm improvement. The order matters because standards must be set before data collection. The other sequences either reverse the steps or omit the comparison and re-audit stages.

Question 8Principles of general practice and primary care

A 68-year-old with multimorbidity attends with a new problem. Applying the principle of 'continuity of care' in general practice, which benefit is best supported?

  1. Reduced need for any medication review
  2. Improved accumulation of contextual knowledge about the patient over time Correct answer.
  3. Elimination of the need for referral
  4. Guaranteed shorter consultation times

Explanation

Continuity of care allows the GP to build contextual knowledge of the patient's history, values and circumstances, which supports better decision-making in multimorbidity. It does not remove the need for medication review or referral, nor does it guarantee shorter consultations. The benefit is relational and informational rather than administrative.

Question 9Principles of general practice and primary care

Which term describes the process by which a GP practice identifies patients due for preventive care, such as influenza vaccination, and invites them to attend?

  1. Triage
  2. Systematic recall Correct answer.
  3. Case finding
  4. Opportunistic screening

Explanation

Systematic recall uses practice registers to identify eligible patients and actively invite them for preventive care at defined intervals. It differs from opportunistic screening, which occurs during a consultation for another reason. Case finding is broader identification of at-risk individuals, and triage is prioritisation of presenting problems.

Question 10Principles of general practice and primary care

A GP is discussing antibiotic prescribing for an upper respiratory tract infection. Which approach best reflects the principle of antimicrobial stewardship in primary care?

  1. Avoiding any discussion of antibiotics with the patient
  2. Prescribing antibiotics to all patients to prevent complications
  3. Using a delayed prescription strategy where appropriate and explaining self-care Correct answer.
  4. Referring every patient with a sore throat to hospital

Explanation

Antimicrobial stewardship in primary care involves avoiding unnecessary antibiotics, using strategies such as delayed prescribing where appropriate, and supporting self-care with clear safety netting. Blanket prescribing drives resistance, and referring all patients or avoiding discussion is neither proportionate nor patient-centred. Shared decision-making is central.

Question 11Principles of general practice and primary care

Which statement best describes the role of the 'gatekeeper' function of general practice within a health system?

  1. The GP sets national clinical guidelines
  2. The GP determines the patient's eligibility for social welfare
  3. The GP manages hospital budgets directly
  4. The GP controls access to secondary care by referral Correct answer.

Explanation

The gatekeeper function refers to the GP acting as the point of first contact who coordinates and authorises access to secondary and specialist care through referral. This role supports continuity and appropriate use of resources. GPs do not set national guidelines, determine welfare eligibility, or directly manage hospital budgets.

Question 12Principles of general practice and primary care

A GP practice is reviewing its approach to patients who frequently attend. Which strategy is most consistent with good primary care management of frequent attenders?

  1. Developing a shared care plan with continuity of carer and attention to psychosocial factors Correct answer.
  2. Placing all frequent attenders on a practice exclusion list
  3. Referring every frequent attender to the emergency department
  4. Restricting appointments to one per patient per year

Explanation

Frequent attendance often reflects unmet physical, psychological or social needs, so a coordinated care plan with continuity of carer and attention to psychosocial factors is the recommended approach. Exclusion, blanket referral or arbitrary appointment limits are punitive and do not address underlying need. Continuity is particularly valuable for this group.

Question 13Principles of general practice and primary care

In the context of the 'biopsychosocial model', which approach best illustrates its application in a general practice consultation?

  1. Treating only the patient's stated physical complaint
  2. Considering biological, psychological and social factors together when formulating the problem Correct answer.
  3. Focusing solely on the pathological cause of symptoms
  4. Referring all psychosocial issues to psychiatry

Explanation

The biopsychosocial model holds that illness and presentation are shaped by interacting biological, psychological and social factors, and formulation should integrate all three. This supports holistic management in general practice. Focusing only on pathology or the physical complaint, or automatically referring psychosocial issues away, does not apply the model.

Question 14Principles of general practice and primary care

Which of the following best describes the concept of 'defensive medicine' as it may arise in Irish general practice?

  1. Auditing prescribing against national guidelines
  2. Using shared decision-making with the patient
  3. Requesting investigations or referrals primarily to reduce perceived personal medico-legal risk Correct answer.
  4. Providing care according to the best available evidence

Explanation

Defensive medicine refers to ordering tests, referrals or treatments primarily to protect against potential medico-legal criticism rather than for clear clinical benefit. It can drive unnecessary investigation and cost. Evidence-based care, shared decision-making and audit are positive practices and are not defensive medicine.

Question 15Principles of general practice and primary care

A GP practice is planning to improve access for patients with disabilities. Which measure best reflects the principle of 'reasonable accommodation' in primary care?

  1. Providing accessible premises, alternative communication and flexible appointment arrangements Correct answer.
  2. Directing patients with disabilities to hospital services
  3. Charging higher fees to patients with additional needs
  4. Requiring all patients to use online booking only

Explanation

Reasonable accommodation means making adjustments so that people with disabilities can access care on an equal basis, such as accessible premises, communication support and flexible appointment arrangements. Requiring online-only booking, charging more, or redirecting patients to hospital would create barriers and is discriminatory. Equity of access is a core primary care principle.

Question 16Principles of general practice and primary care

Which statement best explains why 'continuity of care' is considered a core value in general practice rather than simply a convenience?

  1. It reduces the need for any clinical records
  2. It guarantees that patients will never be referred
  3. It supports trust, accumulated knowledge and better coordination of care over time Correct answer.
  4. It eliminates diagnostic uncertainty

Explanation

Continuity of care is valued because repeated contact with the same clinician builds trust and accumulated knowledge, improving coordination and the quality of decisions across episodes of illness. It does not replace clinical records, remove the need for referral, or eliminate diagnostic uncertainty. Its benefit is relational and longitudinal.

Question 17Consultation and communication skills

A 34-year-old woman attends with a three-day history of sore throat and requests antibiotics. Examination is unremarkable and a Centor score is low. Which consultation approach best demonstrates the principles of prudent antibiotic prescribing in Irish general practice?

  1. Prescribe a broad-spectrum antibiotic because she has already decided she needs one
  2. Prescribe a delayed antibiotic script to end the consultation quickly
  3. Explain the likely viral cause, address her concerns and agree a safety-netting plan without prescribing Correct answer.
  4. Tell her antibiotics are unavailable and avoid discussing the diagnosis

Explanation

Prudent prescribing requires exploring the patient's ideas, concerns and expectations, giving a clear explanation of the likely viral aetiology, and agreeing a contingency or safety-netting plan. This preserves the therapeutic relationship while avoiding unnecessary antimicrobial exposure and resistance pressure. Simply issuing a delayed script without explanation does not address her concerns or educate her.

Question 18Consultation and communication skills

During a consultation, a GP trainee notices the patient has stopped making eye contact and is wringing her hands while describing her father's recent death. What is the most appropriate immediate communication response?

  1. Reassure her that everything will be fine and move on
  2. Acknowledge the observed emotion and pause to allow her to express it Correct answer.
  3. Continue the structured history to ensure all biomedical details are collected first
  4. Change the subject to a less distressing area to protect her

Explanation

Noticing and naming emotional cues is a core consultation skill; pausing and acknowledging the emotion allows the patient to elaborate and builds rapport. Suppressing or deflecting the cue risks missing important psychosocial information and damages the therapeutic alliance. Completing the biomedical history first can come after the emotional cue has been addressed.

Question 19Consultation and communication skills

Which communication model is most commonly used in Irish general practice training to structure the whole consultation, including initiating the session, gathering information, building the relationship and closing?

  1. The Apgar framework
  2. The SBAR handover tool
  3. The Calgary-Cambridge guide Correct answer.
  4. The Glasgow Coma Scale

Explanation

The Calgary-Cambridge guide is a widely taught framework describing the structure and process of the medical interview, including initiating the session, gathering information, physical examination, explanation and planning, and closing. It explicitly integrates communication skills with the tasks of the consultation. The other listed tools serve unrelated clinical or handover purposes.

Question 20Consultation and communication skills

A patient with limited English proficiency attends with chest pain. Which approach best ensures valid consent and safe communication?

  1. Speak slowly and loudly in English and rely on gestures
  2. Arrange a professional interpreter and check understanding with teach-back Correct answer.
  3. Use the patient's young child to interpret to save time
  4. Ask a receptionist with basic language skills to interpret sensitive details

Explanation

Professional interpreting, ideally with a trained interpreter, is required for safe communication and valid consent when language barriers exist. Teach-back confirms that the patient has understood the explanation rather than merely heard it. Using family members, especially children, or untrained staff risks errors, confidentiality breaches and inaccurate interpretation.

Question 21Consultation and communication skills

In motivational interviewing, which technique best reflects the spirit of the approach when a patient is ambivalent about reducing alcohol intake?

  1. Exploring the patient's own reasons for and against change Correct answer.
  2. Listing the reasons the patient should stop drinking
  3. Confronting the patient about the harms of continued drinking
  4. Warning the patient that they will be discharged if they continue

Explanation

Motivational interviewing is collaborative and aims to evoke the patient's own arguments for change, known as change talk, rather than imposing advice. Exploring both sides of ambivalence respects autonomy and reduces resistance. Confrontation and threats tend to increase defensiveness and are contrary to the approach.

Question 22Consultation and communication skills

A GP is explaining a new diagnosis of type 2 diabetes to a patient with low health literacy. Which strategy best supports the patient's understanding and recall?

  1. Provide a detailed leaflet and ask the patient to read it at home
  2. Use medical terminology to ensure accuracy of the explanation
  3. Give all the information in a single long explanation to avoid repetition
  4. Use chunking and check-back, and agree one or two key actions Correct answer.

Explanation

Chunking information into small amounts, checking understanding with teach-back and agreeing a small number of key actions improves comprehension and recall for patients with low health literacy. Written information is a useful adjunct but should not replace a clear spoken explanation. Excessive detail in one sitting and unexplained jargon impair understanding.

Question 23Consultation and communication skills

A 58-year-old man presents with fatigue. During the consultation he mentions that his wife died six months ago and he has been unable to sleep. Which response best demonstrates active listening?

  1. Interrupt to ask about his alcohol intake before the topic changes
  2. Summarise what he has said and reflect the difficulty he is describing Correct answer.
  3. Tell him that grief is normal and change the subject to his blood tests
  4. Nod and remain silent for the rest of the consultation

Explanation

Active listening involves attending, reflecting and summarising what the patient has said so that they feel heard and the GP can confirm understanding. Summarising also helps organise the psychosocial and biomedical information. Interrupting, prolonged silence without structure or dismissing grief all reduce the patient's sense that their concerns are being taken seriously.

Question 24Consultation and communication skills

A GP wishes to discuss a patient's recent diagnosis with the patient's adult daughter, who telephones the surgery. What is the most appropriate response?

  1. Explain that consent is needed and offer to arrange a discussion with the patient's agreement Correct answer.
  2. Refuse to speak to the daughter and end the call immediately
  3. Discuss the diagnosis because the daughter is next of kin
  4. Provide the information but ask the daughter to keep it confidential

Explanation

Confidentiality belongs to the patient, and information should not be disclosed to relatives without the patient's consent or another lawful basis. The GP should explain this sensitively and offer to facilitate a discussion if the patient agrees. Next of kin status does not automatically confer a right to clinical information.

Question 25Consultation and communication skills

A patient becomes angry during a consultation, raising his voice and stating that the practice has repeatedly let him down. Which approach best de-escalates the situation?

  1. Ask him to leave and rebook when he is calmer
  2. Continue the consultation as planned and ignore the anger
  3. Acknowledge his frustration, apologise for his experience and explore the specific concern Correct answer.
  4. Match his tone to establish that you will not be intimidated

Explanation

De-escalation begins with acknowledging the patient's emotion and offering a genuine apology for his experience, which is not an admission of clinical fault. Exploring the specific concern shifts the conversation from emotion to problem-solving and restores a collaborative relationship. Matching anger, dismissing the emotion or abrupt exclusion escalate the situation.

Question 26Consultation and communication skills

A GP is obtaining informed consent for a minor surgical procedure in the treatment room. Which element is essential for the consent to be valid?

  1. A signature on a consent form regardless of discussion
  2. The patient's capacity to understand and voluntarily agree after adequate information Correct answer.
  3. Written confirmation that the patient has no further questions
  4. The presence of a chaperone during the discussion

Explanation

Valid consent requires capacity, sufficient and understandable information about the procedure and its alternatives and risks, and voluntariness free from coercion. A signed form is evidence of the process but is not a substitute for it. A chaperone and written confirmation are good practice in some contexts but are not the defining elements of valid consent.

Question 27Consultation and communication skills

A GP is breaking bad news to a patient about a new cancer diagnosis using the SPIKES framework. Which step immediately follows giving the warning shot and establishing what the patient already knows?

  1. Offering reassurance that the treatment will certainly be successful
  2. Determining how much the patient wants to know
  3. Giving the information in small chunks and checking understanding Correct answer.
  4. Summarising the consultation and arranging follow-up

Explanation

Within SPIKES, after setting up the interview, assessing the patient's perception and obtaining an invitation, the GP gives the information in small, digestible chunks and checks understanding. Determining how much the patient wants to know precedes giving the information. Summarising and follow-up occur at the end, and false reassurance is inappropriate.

Question 28Consultation and communication skills

A GP is discussing a prostate-specific antigen test with a 60-year-old man. Which communication approach best supports shared decision-making about screening?

  1. Recommend the test strongly because it detects cancer early
  2. Present the potential benefits and harms in absolute terms and explore his values Correct answer.
  3. Advise him that the decision is entirely his without offering information
  4. Provide only the benefits to avoid causing anxiety

Explanation

Shared decision-making requires balanced information about benefits and harms, ideally using absolute numbers, together with exploration of the patient's values and preferences. Strongly recommending or withholding information undermines autonomy. Leaving the decision entirely to the patient without support is abdication rather than shared decision-making.

Question 29Consultation and communication skills

A GP trainee is preparing to conduct a telephone consultation for a patient with a possible urinary tract infection. Which practice best preserves safety in this remote consultation?

  1. Confirm identity, use a structured assessment and agree explicit safety-netting Correct answer.
  2. Prescribe based on the first symptom mentioned to keep the call short
  3. Assume the patient's identity without verification because the number is registered
  4. Skip documentation because the consultation is brief

Explanation

Remote consultations require verification of identity, a structured and systematic assessment and explicit safety-netting advice with clear documentation. Assumptions about identity, incomplete prescribing decisions and omitted documentation all introduce clinical risk. Safety-netting should specify what symptoms warrant review and how to access care.

Question 30Consultation and communication skills

During a consultation a patient says: 'I know you think I'm wasting your time.' Which communication technique is most appropriate to explore this statement?

  1. Use a circular or reflective question to explore what has led him to feel that way Correct answer.
  2. Reassure him that he is not wasting time and continue the history
  3. Ignore the comment and return to the physical examination
  4. Offer to end the consultation early to respect his wishes

Explanation

The statement is a cue about the patient's beliefs and the relationship, and exploring it with a reflective or circular question can reveal concerns that shape the consultation. Simply reassuring and continuing may leave the underlying worry unaddressed. Ignoring the comment or ending the consultation prematurely closes down an important opportunity.

Question 31Consultation and communication skills

A GP notices that during consultations with patients from a particular ethnic minority she consistently gives less information and asks fewer questions. Which concept best describes this pattern and its most appropriate remedy?

  1. Cultural competence, achieved by learning a single set of facts about the group
  2. Unconscious bias, addressed through reflection and conscious use of a structured consultation Correct answer.
  3. Clinical uncertainty, managed by referring all such patients onwards
  4. Patient-centred care, requiring no change in behaviour

Explanation

Systematic differences in communication with particular groups suggest unconscious bias, which is best addressed through reflective practice and deliberate use of a structured consultation to ensure equitable information-giving and questioning. Cultural competence is not a fixed body of facts about a group. Referring all patients onwards would avoid rather than address the disparity.

Question 32Consultation and communication skills

A GP is discussing a patient's wish to refuse a recommended treatment. The patient has capacity and understands the consequences. Which response best reflects ethical and legal communication principles?

  1. Persuade the patient to accept treatment by emphasising the doctor's recommendation
  2. Record that the patient lacks capacity because the decision seems unwise
  3. Ask a relative to overrule the patient's decision
  4. Explore the reasons for refusal, ensure understanding and document the informed decision Correct answer.

Explanation

A capacitous patient is entitled to refuse treatment, even where the decision appears unwise, and the GP's role is to explore reasons, ensure the decision is informed and document it. Persuasion that overrides autonomy, involving relatives to overrule the patient, or mislabelling the patient as lacking capacity are all inappropriate. Capacity is decision-specific and not determined by the perceived wisdom of the choice.

Question 33Cardiovascular medicine

A 68-year-old man with permanent atrial fibrillation has a CHA2DS2-VASc score of 3. He has no history of bleeding and normal renal function. According to current guidance, which management is most appropriate?

  1. Start aspirin plus clopidogrel
  2. No antithrombotic therapy is required
  3. Start aspirin monotherapy
  4. Start an oral anticoagulant Correct answer.

Explanation

A CHA2DS2-VASc score of 3 in a man conveys a high annual stroke risk, well above the threshold at which oral anticoagulation gives net benefit. Aspirin is inferior to anticoagulation for stroke prevention in atrial fibrillation and is not an adequate substitute. Therefore a direct oral anticoagulant or warfarin should be offered unless contraindicated.

Question 34Cardiovascular medicine

Which finding on 12-lead ECG is most characteristic of acute ST-elevation myocardial infarction involving the inferior wall?

  1. ST elevation in leads II, III and aVF Correct answer.
  2. ST elevation in V1 to V4
  3. ST depression in II, III and aVF
  4. Peaked T waves in V5 and V6

Explanation

The inferior wall faces leads II, III and aVF, so acute transmural ischaemia there produces ST elevation in those leads. Reciprocal ST depression is often seen in I and aVL. Anterior leads V1-V4 would instead reflect an anterior infarct.

Question 35Cardiovascular medicine

A 24-year-old woman has a resting blood pressure of 158/96 mmHg measured on three separate occasions. She takes no medication and has no symptoms. What is the most appropriate initial step?

  1. Reassure her that young age excludes hypertension
  2. Confirm with ambulatory or home blood pressure monitoring Correct answer.
  3. Start a thiazide diuretic immediately
  4. Arrange urgent renal angiography

Explanation

A single elevated office reading is not sufficient to diagnose hypertension, and white-coat effect is common. Confirming with ambulatory or home monitoring is the recommended next step before committing to lifelong drug therapy. Secondary causes should be considered afterwards if hypertension is confirmed.

Question 36Cardiovascular medicine

Which murmur is classically described as a mid-diastolic rumble with an opening snap heard best at the apex?

  1. Aortic stenosis
  2. Mitral regurgitation
  3. Mitral stenosis Correct answer.
  4. Aortic regurgitation

Explanation

Mitral stenosis produces turbulent flow across a narrowed valve in diastole, generating a low-pitched mid-diastolic rumble at the apex, often preceded by an opening snap. Aortic stenosis gives a systolic ejection murmur, while regurgitant lesions give systolic or early diastolic murmurs.

Question 37Cardiovascular medicine

A patient with chronic heart failure has persistent breathlessness despite maximal tolerated doses of an ACE inhibitor, beta-blocker and loop diuretic, with an ejection fraction of 30%. Which additional agent has a proven mortality benefit in this setting?

  1. Furosemide dose escalation alone
  2. Mineralocorticoid receptor antagonist Correct answer.
  3. Amlodipine
  4. Digoxin

Explanation

Mineralocorticoid receptor antagonists such as spironolactone or eplerenone reduce mortality in heart failure with reduced ejection fraction when added to standard therapy. Digoxin reduces hospitalisation but not mortality. Amlodipine is neutral in outcome terms.

Question 38Cardiovascular medicine

Which of the following is a recognised modifiable risk factor most strongly associated with the development of peripheral arterial disease?

  1. Cigarette smoking Correct answer.
  2. High dietary fibre intake
  3. Regular aerobic exercise
  4. Female sex

Explanation

Smoking is the strongest modifiable risk factor for peripheral arterial disease and accelerates atherosclerotic change in the lower limb arteries. Dietary fibre and regular exercise are protective rather than causative. Female sex is not a risk factor.

Question 39Cardiovascular medicine

A 55-year-old man presents with sudden-onset tearing chest pain radiating to the back. Blood pressure is 180/100 mmHg in the right arm and 150/90 mmHg in the left arm. Which diagnosis should be considered first?

  1. Aortic dissection Correct answer.
  2. Pericarditis
  3. Stable angina
  4. Pulmonary embolism

Explanation

Sudden tearing pain radiating to the back with an inter-arm blood pressure difference is the classic presentation of aortic dissection. Immediate imaging and blood pressure control are required. The other options do not typically produce inter-arm discrepancy.

Question 40Cardiovascular medicine

A patient on warfarin for a metallic mitral valve has an INR of 6.5 and no bleeding. Which is the most appropriate immediate action?

  1. Withhold warfarin and consider oral vitamin K Correct answer.
  2. Transfuse platelets
  3. Continue the same warfarin dose
  4. Give intravenous thrombolysis

Explanation

An INR of 6.5 without bleeding requires withholding warfarin and, depending on the value and bleeding risk, low-dose oral vitamin K. High INR with mechanical valves carries both bleeding and thrombotic risk, so abrupt reversal with concentrates is reserved for major bleeding. Continuing the same dose would worsen the coagulopathy.

Question 41Cardiovascular medicine

Which ECG feature is most consistent with hyperkalaemia in a patient with acute kidney injury?

  1. Delta wave with short PR interval
  2. Diffuse ST elevation with PR depression
  3. Tall tented T waves with widened QRS Correct answer.
  4. Sawtooth flutter waves

Explanation

Hyperkalaemia initially produces tall peaked T waves and, as potassium rises, QRS widening and sine-wave patterns. Diffuse ST elevation with PR depression suggests pericarditis. Sawtooth waves indicate atrial flutter, and a delta wave indicates pre-excitation.

Question 42Cardiovascular medicine

A 70-year-old woman with heart failure and an ejection fraction of 25% develops persistent atrial fibrillation with a ventricular rate of 130 beats per minute. She is haemodynamically stable. Which drug is most appropriate for rate control?

  1. Adenosine
  2. Bisoprolol Correct answer.
  3. Flecainide
  4. Verapamil

Explanation

Beta-blockers such as bisoprolol are first-line for rate control in heart failure with reduced ejection fraction and are also prognostically beneficial. Non-dihydropyridine calcium channel blockers like verapamil are negatively inotropic and should be avoided. Flecainide is contraindicated in structural heart disease, and adenosine is used for supraventricular tachycardia, not rate control.

Question 43Cardiovascular medicine

Which finding best supports a diagnosis of cardiac tamponade in a patient with a large pericardial effusion?

  1. Bounding pulses and wide pulse pressure
  2. Pansystolic murmur at the apex
  3. Pleural rub with inspiration
  4. Pulsus paradoxus and raised JVP Correct answer.

Explanation

Tamponade impairs diastolic filling, causing pulsus paradoxus, raised jugular venous pressure and hypotension. Bounding pulses with wide pulse pressure suggest aortic regurgitation. A pansystolic apical murmur suggests mitral regurgitation, and a pleural rub suggests pleurisy.

Question 44Cardiovascular medicine

A 62-year-old man with diabetes and hypertension has an LDL cholesterol of 4.2 mmol/L. He has no established cardiovascular disease. According to risk-based lipid guidance, which intervention is most appropriate?

  1. No lipid-lowering therapy
  2. Start a moderate-intensity statin Correct answer.
  3. Start a fibrate alone
  4. Start ezetimibe alone

Explanation

Diabetes with additional risk factors places him at high cardiovascular risk, and statin therapy is recommended for primary prevention. Ezetimibe and fibrates are not first-line monotherapy in this context. Lifestyle advice alone is inadequate given his risk profile.

Question 45Cardiovascular medicine

A patient with known aortic stenosis presents with exertional syncope. What does this symptom indicate about the disease?

  1. It is a marker of severe disease with a poor prognosis Correct answer.
  2. It excludes the need for valve intervention
  3. It suggests only mild stenosis
  4. It is unrelated to the valve severity

Explanation

Exertional syncope, angina or dyspnoea in aortic stenosis marks the onset of severe disease and is associated with a poor prognosis without intervention. These symptoms are a class I indication for aortic valve replacement. They do not indicate mild disease.

Question 46Cardiovascular medicine

Which mechanism best explains the benefit of cardiac resynchronisation therapy in selected patients with heart failure?

  1. Reducing preload by venodilation
  2. Increasing heart rate to improve output
  3. Restoring coordinated ventricular contraction in the presence of bundle branch block Correct answer.
  4. Blocking the renin-angiotensin system

Explanation

Cardiac resynchronisation therapy uses biventricular pacing to correct dyssynchrony, typically in patients with left bundle branch block and a wide QRS. This improves ventricular efficiency and symptoms. It does not act through venodilation, chronotropy or neurohormonal blockade.

Question 47Cardiovascular medicine

A 35-year-old woman has a blood pressure of 170/110 mmHg and is 28 weeks pregnant. Which antihypertensive is most appropriate for treating severe hypertension in pregnancy?

  1. Ramipril
  2. Labetalol Correct answer.
  3. Atenolol
  4. Spironolactone

Explanation

Labetalol is a first-line agent for severe hypertension in pregnancy and is well established for safety. ACE inhibitors such as ramipril are contraindicated because of fetal renal toxicity. Atenolol is associated with fetal growth restriction, and spironolactone is not used for this indication.

Question 48Cardiovascular medicine

A 60-year-old man has palpitations and a regular narrow-complex tachycardia at 180 beats per minute with no visible P waves. He is haemodynamically stable. Which manoeuvre is the most appropriate first step?

  1. Oral bisoprolol
  2. Intravenous amiodarone
  3. Vagal manoeuvres such as the Valsalva manoeuvre Correct answer.
  4. Immediate synchronised DC cardioversion

Explanation

A regular narrow-complex tachycardia without P waves is most likely AV nodal re-entrant or AV re-entrant tachycardia. In a stable patient, vagal manoeuvres are first-line to increase AV nodal refractoriness and terminate the arrhythmia. Synchronised cardioversion is reserved for instability, and amiodarone is not first-line.

Question 49Cardiovascular medicine

A 45-year-old man with a strong family history of premature coronary disease has a fasting total cholesterol of 8.5 mmol/L and tendon xanthomas. Which diagnosis is most likely?

  1. Familial combined hyperlipidaemia
  2. Nephrotic syndrome
  3. Hypothyroidism
  4. Familial hypercholesterolaemia Correct answer.

Explanation

Markedly elevated LDL cholesterol with tendon xanthomas and a strong family history is characteristic of familial hypercholesterolaemia. This condition requires aggressive lipid-lowering therapy and family cascade screening. Secondary causes should still be excluded, but the clinical picture is classic.

Question 50Cardiovascular medicine

A patient with severe aortic stenosis has a mean gradient of 25 mmHg, an ejection fraction of 30% and a calculated valve area of 0.8 cm2. Which concept best explains these findings?

  1. Low-flow low-gradient aortic stenosis Correct answer.
  2. Moderate aortic stenosis
  3. Normal-flow high-gradient stenosis
  4. Aortic sclerosis without stenosis

Explanation

Reduced ejection fraction can lower transvalvular flow and therefore the measured gradient despite a severely narrowed valve area. This pattern is termed low-flow low-gradient aortic stenosis and often requires dobutamine stress echocardiography to confirm severity. A high gradient would be expected if flow were preserved.
