High-yield topic

Pharmacology for Nursing Exams

Pharmacology runs through every NCK paper, not just one subject. Questions test how drugs work, their side effects, and the nurse's responsibilities around them. Here are the high-yield drug classes and how to answer pharmacology MCQs.

High-yield drug classes

Antibiotics

Classes (penicillins, cephalosporins, aminoglycosides), allergy and resistance, nursing responsibilities.

Analgesics — opioids & NSAIDs

Morphine and pethidine effects, respiratory depression, NSAID gastric and renal cautions.

Antihypertensives

ACE inhibitors, beta-blockers, diuretics, calcium-channel blockers; key side effects and monitoring.

Antidiabetic agents

Insulin types and onset/peak/duration, metformin, recognising and managing hypoglycaemia.

Anticoagulants

Heparin vs warfarin, monitoring (APTT, INR), antidotes and bleeding precautions.

Respiratory drugs

Bronchodilators and corticosteroids in asthma and COPD, inhaler technique.

Antiretrovirals (ARVs)

First-line regimens, adherence, common side effects and drug interactions.

Anti-TB & antimalarials

TB regimen phases and side effects (e.g. isoniazid, rifampicin), artemisinin-based combinations.

Psychotropic drugs

Antipsychotics, mood stabilisers and antidepressants; extrapyramidal and other adverse effects.

Drug calculations

Dosage, IV flow rates and paediatric weight-based dosing — a common source of lost marks.

What pharmacology questions test

  • Mechanism of action — what the drug does and why it is given.
  • Side effects and toxicity — what to watch for and report.
  • Nursing responsibilities — checks before, during and after giving a drug.
  • Contraindications and interactions — when a drug must not be used.
  • Drug calculations — getting the dose and flow rate right.

How to revise pharmacology

Do not memorise drugs in isolation. Learn them by class — once you know how a class works, you can reason out individual drugs. Practise plenty of multiple-choice questions, drill your calculations until they are automatic, and read the explanation behind every answer.
