Medical Knowledge and Clinical Practice
What the exam tests
Expect questions that probe safe, guideline-concordant clinical reasoning rather than obscure trivia. Core areas recur: cardiovascular emergencies (ACS, arrhythmia, heart failure), sepsis recognition and the sepsis-six bundle, acute asthma and COPD exacerbations, diabetic ketoacidosis and hypoglycaemia, stroke thrombolysis windows, acute kidney injury and fluid/electrolyte correction, and safe prescribing (renal dosing, interactions, anticoagulation). Basic sciences - physiology, pharmacology, microbiology - are usually tested through a clinical vignette, so always translate the mechanism into a management decision.
Concepts to master
Know the first-line investigation and the immediate management for each emergency, the contraindications to thrombolysis, the criteria for sepsis, the anion gap in metabolic acidosis, and the standard antibiotic choices for common infections. Understand consent and capacity as they apply to urgent treatment. Resuscitation algorithms (adult BLS/ALS) and safe prescribing principles are high-yield.
Traps
Questions often present a near-miss: a normal-looking early vital sign in sepsis, a 'normal' ECG in evolving ACS, or a patient with a single deranged electrolyte where the underlying cause (e.g. diuretic use) matters more than the number. Read for the most appropriate next step, not the most dramatic one. Watch units and reference ranges.
Worked rule of thumb
For any acute vignette ask three questions in order: (1) Is this immediately life-threatening? (2) What is the single most useful investigation? (3) What is the safest first action? Example: a hypotensive, febrile patient with a lactate of 4 - the answer is not 'await cultures' but 'start empirical antibiotics and fluids within the hour, cultures first if no delay'.
Revision strategy
Use spaced repetition on algorithms and drug doses; practise interpreting ECGs, ABGs and blood results under time pressure.
