Medicines management in the CRA tests the pharmacist's core clinical function: reviewing a patient's medication regimen, identifying problems, and recommending appropriate changes. These questions reward systematic thinking — and penalise candidates who rush.
High-Yield Areas
Identifying prescribing errors. Wrong dose, wrong drug, wrong patient, wrong route, wrong frequency. The question presents a prescription or medication list with an embedded error — you must identify it. Medicines reconciliation. Comparing medication lists across care transitions (admission, discharge, transfer). Identifying discrepancies. Ensuring continuity. Dose adjustments. Renal impairment (eGFR-based dose adjustment per BNF), hepatic impairment, elderly patients, paediatric dosing, pregnancy/breastfeeding. Drug interactions in polypharmacy. A patient taking 8+ medications — which interaction is clinically significant? This requires systematic checking, not just recognising individual interactions. Formulation switching. Liquid to tablet, IV to oral step-down, modified-release to immediate-release. Ensuring bioequivalence and appropriate dosing.
Question Structure
A patient scenario with a medication list. You are asked to identify the problem or recommend a change. The skill is systematic checking: each medicine checked against the patient's conditions, renal function, hepatic function, allergies, age, pregnancy status, and other medications. Miss one check and you miss the answer.
Common Mistakes
Not checking renal function before answering (many dose-dependent questions hinge on this). Missing drug-drug interactions in a long medication list (the interaction is often between the 3rd and 7th drug on the list, not the obvious ones). Overlooking allergy status (penicillin allergy + prescribed co-amoxiclav). Not recognising when a dose needs adjusting for a special population.
Study Approach
Practise with medication list scenarios — not just individual drug questions. Build the systematic checking habit: patient factors → drug factors → interactions → dose → monitoring. Review BNF cautions and interactions sections alongside clinical scenarios.
