Foreword A continuing pursuance of clinical excellence can be a long and difficult path to follow. Nevertheless, it is something we all aspire to in order to use our best knowledge in serving our patients. But first, one has to pass the qualifying examination! This book helps to test your knowledge and aims to provide a question and answer format that closely follows the curriculum for Finals.

It reflects the clinical scenarios that medical students will encounter when they first start as doctors and also face in Finals. It follows the single best answer format; a format of questioning that is more like real life. The authors have given comprehensive and informative answers, as well as reasons for the choice of the correct answer. It is very readable. It is also refreshing to see that the authors have combined together to write this text from a wide range and level of knowledge — from a final year medical student to a professor.

They will all remember what Finals entailed, from the sheer anxiety to the excitement of getting the knowledge of medicine into focus. I am sure this book will be useful and enjoyable. Good luck for Finals!

This page intentionally left blank Preface Medical schools have undergone a number of changes in deciding upon the ideal format for testing clinical knowledge in examinations. Multiple choice questions MCQs in the past were the most common modality by which medical students were examined.

Although able to test a broad range of topics and being cost efficient for marking purposes, MCQs have largely been abandoned in favour of extending matching questions EMQs and more recently the single best answer SBA question format. EMQs and SBAs overcome the ambiguity that occurs in MCQ exams, as well as being able to provide more clinical question stems reflecting real-life situations.

The SBA format is highly favoured in examinations at both the undergraduate and postgraduate level since students must not only demonstrate their clinical knowledge and understanding but also make sound judgements which are more congruent with clinical practice. Each question not only provides an opportunity to apply clinical knowledge and correctly identify the single best answer to a question, but also to learn why the other answers are wrong, greatly increasing the clinical acumen and learning opportunity of the reader.

This area is represented by leads V5—6 D. V1—4 represents the territory of the left anterior descending artery.

If the entire left mainstem had been occluded, changes would have shown throughout leads V1—6 B. Structure your knowledge for success in medical exams, Cavaye, with permission. Cardiovascular The location of the changes tells you which part of the heart is affected as shown in the diagrams.

These depict: Putting all of these together will allow you to pinpoint the location of the lesion. Posterior descending branch Heart failure 2 D Aortic stenosis will first result in left ventricular failure as a result of increased ventricular pressure as the ventricle tries to pump blood across a narrowed valve. Initially the pressure load will cause a backlog of blood into the lungs, resulting in pulmonary oedema — the first sign of which will be bibasal crepitations D before enough fluid accumulates as pleural effusions visible on chest x-ray A.

Earlier signs of pulmonary oedema include upper lobe blood diversion and Kerley B lines as fluid infiltrates the interstitium. If the backlog continues back into the right heart, eventually signs of right-sided heart failure will be evident including raised JVP B and bilateral pedal oedema C. Atrial fibrillation E may coexist with aortic stenosis, however it is more commonly associated as a result of mitral stenosis as the enlarged atrium disrupts the normal electrical pathways.

Valve lesion signs 3 B A murmur heard loudest on inspiration A points to a right-sided valve lesion. The right intercostal space midclavicular line C is the anatomical landmark for the aortic valve.

The mitral area is over the apex. A murmur louder with the patient in the left lateral position B as opposed to leaning forward is associated with mitral lesions. If heard, you should determine whether the murmur radiates to the axilla. A narrow pulse pressure E is a sign of aortic stenosis. There is no indication for hypoglycaemics at present. There is no indication that this is acute atrial fibrillation and she does not seem to be compromised in a female of this age, cardioversion C is unlikely to be successful.

She should be rate-controlled but the beta blockade is more appropriate in light of her ischaemic heart disease. Whether to start anticoagulation A is a decision that has to be tailor-made for each individual patient. The CHAD2 score is a quick and dirty but very useful way of predicting risk of subsequent stroke as a result of atrial fibrillation and helps guide the prescription of prophylactic antiplatelets or anticoagulants. Other factors, such as ease of taking and monitoring warfarin, risk of falls and important risk factors, such as vascular disease, should be taken into account.

C Congestive heart failure 1 H Hypertension: A score of 1 is moderate risk 3 per cent annual stroke risk and either warfarin or aspirin D is indicated according to the individual. Chest pain 5 C Acute coronary syndrome is a spectrum of cardiac ischaemia-infarction determined by the presence of two out of three factors: Depending on these results, patients will fall into one of the following categories: ST elevation, Q waves and raised troponin are indicative of infarction.

ST elevation C is a very good predictor of imminent infarction positive troponin. However, if this patient is treated quickly enough with thrombolysis or primary PCI, infarction can be avoided. Patients most often complain of shortness of breath, pleuritic chest pain and haemoptysis. Clinical signs can include a pleural rub, coarse crackles and atrial fibrillation. In massive pulmonary embolism there can be a raised JVP, respiratory rate, heart rate and hypotension.

The Geneva scoring system see below is useful for predicting the risk of a pulmonary embolism: Muscular strain A typically occurs on movement and is not associated with shortness of breath or leg pain and there is usually an indicator of injury or a preceding stressor. Heart failure B is unlikely due to the acute presentation of symptoms which tend to occur more insidiously and can be associated with bilateral leg oedema, murmurs, orthopnoea or hepatomegaly, among others.

A pneumothorax C can present with a similar pleuritic chest pain that occurs in an embolism, however, there is no association with limb pain and a respiratory examination is likely to reveal hyper-resonance.

Angina D is typically described as a dull or crushing chest pain in the centre of the chest, patients have risk factors such as diabetes, hyperlipidaemia, obesity, smoking and hypertension.

Answers 21 Murmurs 7 A This patient is suffering from a mitral valve prolapse Barlow syndrome, click murmur syndrome A. A mid-systolic click followed by a late systolic murmur is heard at the apex as the thickened mitral valve leaflet is displaced into the left atrium during systole.

An Austin Flint murmur B produces a low pitched, mid-diastolic rumble at the apex. Classically, mitral valve displacement as well as aortic turbulence due to regurgitation qualifies as an Austin Flint murmur. A patent ductus arteriosus C produces a constant machinery murmur. A Graham Steell murmur D is typically heard best at the left sternal edge, second intercostals space during inspiration.

A high pitched early diastolic murmur is heard associated with pulmonary hypertension. A Carey Coombs murmur E is a short, mid-diastolic rumble heard best at the apex due to turbulent blood flow over a thickened mitral valve, most often due to rheumatic fever.

Chest pain 8 C All of the answer options can present as central chest pain, however the patient describes a very typical description of an aortic dissection C , usually a severe, tearing pain that radiates toward the back though this can be to the jaw depending on the location of the dissection.

An MI A is typically described as severe, crushing chest pain with an acute onset, this patient has been suffering from a 3-day history of chest pain which makes an infarction unlikely. Although myocardial ischaemia B , i.

A pulmonary embolism D typically presents with pleuritic chest pain, cough and haemoptysis which are not present in this patient, or preceding risk factors such as long haul travel or surgery. Pneumonia E is associated with fever and productive coughing.

Since the patient has had an adequate response to GTN spray, further pain relief in the form of morphine B is unnecessary. In patients who are not allergic, mg of aspirin is recommended and ideally should be given in the ambulance. Although heparin C and warfarin E would provide good anticoagulant cover, they are slower to act and current guidance advises clopidogrel monotherapy D in those patients allergic to aspirin.

Cardiovascular Ventricular tachyarrhythmia 10 B This patient is suffering from a life-threatening ventricular tachyarrhythmia of which there are two types, sustained ventricular tachycardia and ventricular fibrillation. In ventricular fibrillation B the patient is pulseless and cardioversion is required.

If stable, patients can be cardioverted with amiodarone, if unstable, electrocardioversion is required. Torsades de pointes A presents with irregular QRS complexes and prolonged QT interval, a non-sustained ventricular tachycardia D is defined by more than five consecutive heart beats within 30 seconds, while a normal heart ventricular tachycardia E is a benign tachyarrhythmia.

Answers A , D and E are not shockable rhythms. Jugular venous pressure 11 D The JVP provides clinicians with information regarding right atrial pressures and filling. It mainly consists of five wave forms: A raised JVP with normal waveform pattern A is usually seen in fluid overload and right heart failure.

Large v waves B are usually seen in patients with tricuspid regurgitation. Heart failure 12 A Cardiomegaly B , bilateral pleural effusions C , alveolar oedema D and Kerley B lines E representing interstitial oedema are all features that can be seen in a chest x-ray in patients with congestive cardiac failure.
