What Changes Each Year — and What Never Does
If you have been searching for NMCN pharmacology questions by year, you probably want to know one thing: are this year's questions going to look different from previous years, or is it the same pattern with different numbers?
The honest answer is both.
The topics the NMCN examiners keep returning to — digoxin, insulin, anticoagulants, antibiotics, drug calculations — have stayed consistent since 2012. But the way questions are framed shifts from year to year. A 2020 paper might ask about digoxin toxicity using one clinical scenario. A 2024 paper asks the same concept but wraps it in a different patient presentation. If you studied only one year's questions, you might recognise the drug but still choose the wrong option because the framing caught you off guard.
That is why year-by-year study matters. Not just knowing what topics repeat — but seeing how the same topic has been tested in different ways across multiple sittings.
FreshNote holds the complete pharmacology question bank from 2012 through 2026. You can work through questions by year, by topic, or in full mixed-paper CBT mode. Start at the NMCN CBT question bank on FreshNote and select pharmacology to see what is available for each sitting.
How NMCN Pharmacology Has Evolved from 2020 to 2026
2020 — Foundations Under Pressure
The 2020 NMCN pharmacology papers leaned heavily on foundational drug knowledge. Questions in this sitting focused primarily on:
- Basic drug classifications — students needed to correctly identify which class a drug belonged to
- Standard nursing considerations before administering high-alert drugs
- Dose calculations using straightforward whole numbers
The 2020 papers were broadly seen as testing depth of foundational knowledge rather than complex clinical reasoning. If you got your classifications and pre-administration checks right, you scored well.
Standout topic from 2020: Sensitivity testing before antibiotic administration. Questions asked which drugs require a skin test before the first dose and what the nurse should do if a reaction occurs.
2021 — Toxicity Takes Centre Stage
The 2021 sitting saw a noticeable shift toward drug toxicity scenarios. More questions were framed as "a patient on [drug] presents with [symptoms] — what does the nurse do?" rather than simple classification or recall questions.
This pattern change caught students who had only memorised drug names and actions off guard. Knowing that gentamicin is an aminoglycoside antibiotic is not enough. The 2021 questions required knowing what nephrotoxicity looks like in a patient, what signs trigger a dose review, and what the nurse reports to the prescriber.
Standout topic from 2021: Aminoglycoside toxicity — both nephrotoxicity and ototoxicity appeared as separate questions in the same sitting, framed differently. One asked about a patient with decreased urine output on gentamicin. Another described tinnitus and dizziness in a patient on streptomycin and asked the nurse to identify the likely cause.
2022 — Drug Interactions Enter the Picture
By 2022, drug interaction questions had become a reliable fixture in NMCN pharmacology papers. This was a meaningful evolution from earlier years, where interactions were rarely tested directly.
The 2022 papers introduced questions on:
- Metronidazole and alcohol — the disulfiram-like reaction
- Warfarin and aspirin — compounded bleeding risk
- Antacids and tetracycline — impaired drug absorption when taken together
- ACE inhibitors and potassium-sparing diuretics — hyperkalaemia risk
Students who had studied only 2019 and 2020 questions were caught by these interaction questions because they were barely represented in earlier years. This is why studying across multiple years matters — you see the evolution of what examiners consider fair to test.
Standout topic from 2022: The metronidazole-alcohol interaction appeared in both the General Nursing and Midwifery sittings of that year, framed slightly differently in each.
2023 — Patient Education Questions Increase
The 2023 NMCN pharmacology papers brought a clear increase in patient education and discharge instruction questions. These go beyond knowing what a drug does — they test whether the nursing student can explain drug safety to a patient in a practical way.
Common 2023 question formats:
- "A patient on warfarin is about to be discharged. Which of the following is the most important instruction to give her?"
- "A patient starting on oral iron tablets asks why her stools have changed colour. What is the correct nursing response?"
- "A patient prescribed metronidazole asks if she can drink alcohol during the treatment course. What does the nurse tell her?"
These questions require you to think from the patient's perspective, not just the clinical one. The correct answer is not always the most medically detailed — it is the most relevant and appropriate thing to tell a patient at that moment.
Standout topic from 2023: Anticoagulant patient education. Questions on warfarin discharge instructions appeared multiple times, each with a different set of options designed to test whether students understood the bleeding risk in practical terms.
2024 — Calculations Get More Complex
The 2024 pharmacology papers maintained all the topic categories from previous years but made calculation questions noticeably more layered. Instead of simple one-step dose calculations, the 2024 papers introduced two-step scenarios:
A patient weighing 60kg is prescribed gentamicin at 3mg/kg/day in two divided doses. The available concentration is 40mg/2ml. How many millilitres does the nurse draw up per dose?
This requires three steps: calculate total daily dose (60 × 3 = 180mg), divide for each dose (180 ÷ 2 = 90mg per dose), then calculate volume (90 ÷ 40 × 2 = 4.5ml).
Students who had only practised single-step calculations were slower on these questions and sometimes ran out of time in Paper II.
Standout topic from 2024: Weight-based dosing calculations. These appeared for gentamicin, which requires weight-based dosing in clinical practice, and also for paediatric drug questions in the same paper.
2025 — Obstetric Pharmacology Gets More Specific
The 2025 sittings — particularly the Midwifery papers in March and September — expanded pharmacology questions related to obstetric drug management. This reflected the growing emphasis on evidence-based midwifery practice in Nigerian nursing education.
New territory in 2025 pharmacology:
- Magnesium sulphate for eclampsia management — dosage, monitoring, and toxicity signs
- Tocolytic drugs — which are used to stop preterm labour and their maternal side effects
- Corticosteroids for fetal lung maturity — timing and nursing responsibilities
- Ergometrine vs oxytocin — when each is used and why
For General Nursing candidates, 2025 papers continued the 2024 trend of weight-based calculations and added more questions on paediatric drug dosing — a reflection of the updated NMCN curriculum emphasis on paediatric nursing.
Standout topic from 2025: Magnesium sulphate toxicity. Signs of toxicity (absent knee-jerk reflex, respiratory rate below 12, reduced urine output) and the antidote (calcium gluconate) appeared across both the March Midwifery and November General Nursing papers.
2026 — What the Current Papers Are Testing
Based on the 2026 sittings so far — March Midwifery and May General Nursing — the current pharmacology pattern shows:
- Drug interaction questions have held steady at a higher frequency than pre-2022 levels
- Patient education questions remain a consistent category
- Calculation questions continue to include weight-based and paediatric scenarios
- A new emphasis on drug storage and cold chain questions, particularly for vaccines and insulin
- More questions on newer antihypertensive classes — ARBs (Angiotensin Receptor Blockers) now appearing alongside the traditional beta-blockers and calcium channel blockers
The core topics — digoxin, insulin, anticoagulants, aminoglycosides, oxytocics — remain present. But students preparing only from 2020 papers will miss the evolution in how those topics are framed.
Year-by-Year Summary: What Each Sitting Emphasised
| Year | Primary Pharmacology Focus | Notable New Territory |
|---|---|---|
| 2020 | Classifications, sensitivity testing, basic calculations | Antibiotic skin testing scenarios |
| 2021 | Drug toxicity, aminoglycosides, clinical signs | Ototoxicity and nephrotoxicity as separate questions |
| 2022 | Drug interactions | Metronidazole-alcohol, warfarin-aspirin, antacid-tetracycline |
| 2023 | Patient education, discharge instructions | Anticoagulant counselling, iron side effects |
| 2024 | Complex calculations, weight-based dosing | Paediatric dosing, multi-step calculations |
| 2025 | Obstetric pharmacology, magnesium sulphate | Tocolytics, corticosteroids, MgSO4 toxicity |
| 2026 | Drug storage, ARBs, interactions (continued) | Cold chain questions, newer antihypertensives |
Sample Questions Reflecting Each Year's Style
These are new questions — not repeats from earlier FreshNote articles — each styled after the dominant format of that year's papers.
2020 Style — Classification and Pre-Administration Check
Question 1
Before administering crystalline penicillin to a patient for the first time, the nurse must:
A. Check the patient's blood pressure
B. Perform a sensitivity test and observe for 15–30 minutes
C. Ensure the patient has not eaten in the last 2 hours
D. Draw blood for a full blood count
Answer: B — Perform a sensitivity test
Penicillin carries a risk of anaphylaxis on first exposure. A skin sensitivity test must be done, and the patient observed for a reaction period before the full dose is given. This was a signature 2020-style question — testing pre-administration safety checks.
2021 Style — Toxicity Recognition
Question 2
A patient on streptomycin therapy tells the nurse she has been experiencing ringing in her ears and feels unsteady when walking. The nurse recognises these as signs of:
A. Penicillin allergy
B. Streptomycin ototoxicity
C. Normal adjustment to antibiotic therapy
D. Fluid and electrolyte imbalance
Answer: B — Streptomycin ototoxicity
Tinnitus (ringing in ears) and vestibular disturbance (unsteadiness) are classic signs of eighth cranial nerve damage from aminoglycoside antibiotics. The nurse should withhold the drug and report immediately. This mirrors the 2021 pattern of testing toxicity recognition in a patient scenario.
2022 Style — Drug Interaction
Question 3
A patient on metronidazole comes to the ward smelling of alcohol. She complains of severe flushing, headache, and nausea. The nurse suspects:
A. Metronidazole allergic reaction
B. Disulfiram-like reaction from alcohol and metronidazole interaction
C. Metronidazole overdose
D. Alcohol poisoning unrelated to her medication
Answer: B — Disulfiram-like reaction
Metronidazole inhibits aldehyde dehydrogenase. When alcohol is consumed simultaneously, acetaldehyde accumulates, causing flushing, nausea, vomiting, and headache. Patients must be counselled to avoid all alcohol during metronidazole therapy. This exact scenario type defined the 2022 pharmacology papers.
2023 Style — Patient Education
Question 4
A patient prescribed warfarin for atrial fibrillation is being discharged. She asks the nurse if she can take aspirin for her headaches. The correct nursing response is:
A. "Yes, aspirin is a mild painkiller and will not affect your warfarin"
B. "Avoid aspirin — it increases your bleeding risk when taken with warfarin. Use paracetamol instead"
C. "Take aspirin only when the headache is severe"
D. "Check with the pharmacist, but aspirin is generally safe"
Answer: B — Avoid aspirin, use paracetamol
Both warfarin and aspirin have anticoagulant and antiplatelet effects respectively. Combining them significantly raises the risk of serious bleeding. Paracetamol is the safe alternative for pain relief in anticoagulated patients. This discharge counselling format dominated 2023 pharmacology papers.
2024 Style — Weight-Based Calculation
Question 5
A child weighing 20kg is prescribed amoxicillin at 25mg/kg/day in three divided doses. The available suspension is 125mg per 5ml. How many millilitres should the nurse give per dose?
A. 5ml
B. 6.7ml
C. 10ml
D. 13.3ml
Answer: B — 6.7ml
Step 1: Total daily dose = 20 × 25 = 500mg
Step 2: Dose per administration = 500 ÷ 3 = 166.7mg
Step 3: Volume = (166.7 ÷ 125) × 5 = 6.7ml
Multi-step paediatric calculations like this became a consistent feature of 2024 pharmacology papers. Practise each step separately before combining them.
2025 Style — Obstetric Pharmacology
Question 6
A patient receiving IV magnesium sulphate for severe pre-eclampsia is found to have a respiratory rate of 10 breaths per minute and absent knee-jerk reflexes. What is the nurse's immediate action?
A. Increase the infusion rate to improve drug effect
B. Stop the magnesium sulphate infusion and administer calcium gluconate IV
C. Reduce the infusion rate by half and continue monitoring
D. Reposition the patient and reassess after 15 minutes
Answer: B — Stop the infusion and give calcium gluconate IV
Absent patellar reflexes and a respiratory rate below 12 are signs of magnesium toxicity. The infusion must be stopped immediately. Calcium gluconate is the specific antidote and must be drawn up and available at the bedside whenever magnesium sulphate is being infused. This was the defining pharmacology question type of 2025.
2026 Style — Drug Storage and Cold Chain
Question 7
A community health nurse is preparing a vaccines outreach session. She notices the insulin supply in the cold box has been accidentally frozen overnight. What is the correct action?
A. Allow the insulin to thaw at room temperature and use it
B. Warm the insulin in hot water to restore it
C. Discard the frozen insulin — it should not be used
D. Use the insulin immediately before it deteriorates further
Answer: C — Discard the frozen insulin
Freezing denatures insulin, destroying its potency and safety. Frozen insulin must never be used even after thawing. This question type — testing drug storage knowledge in a community or outreach setting — has become more frequent in 2026 papers, particularly for Community Health and Midwifery candidates.
How to Use Year-by-Year Questions in Your Preparation
Knowing the trend is useful. But it only pays off if you use it correctly.
Start from 2020 and move forward. Work through older years first to lock in foundational knowledge. Then work through 2023, 2024, 2025, and 2026 questions to build the newer skills — complex calculations, drug interactions, patient education scenarios.
Do not skip years with "boring" content. Students who skip 2020 and 2021 because they think recent papers are more relevant often find gaps in their toxicity and classification knowledge. Every year builds on the last.
Treat each year as a separate mock sitting. Set a timer, answer a full year's pharmacology questions in one session, score yourself, then review every wrong answer before moving to the next year. This builds both knowledge and exam stamina simultaneously.
Track which topics you miss across years. If you get calculation questions wrong in 2020, 2022, and 2024, that is a pattern — not a one-off. Those three wrong answers tell you exactly where your biggest pharmacology gap is.
The full collection — from 2012 through 2026 — is available through FreshNote's nursing exam question bank. You can filter by year, by subject, or run a full mixed-paper mock that combines pharmacology with the rest of Paper II the same way the real exam does.

Frequently Asked Questions
Which year of NMCN pharmacology questions is most important to study?
All years from 2020 to 2026 are relevant. Older years (2020–2021) build foundational knowledge on classifications and toxicity. Recent years (2023–2026) reflect the current exam style — patient education, complex calculations, obstetric pharmacology, and drug interactions. Both matter.
Did NMCN pharmacology questions get harder in recent years?
The content has not become harder, but the question format has become more layered. Single-step calculations have been replaced by multi-step scenarios. Simple recall questions have been joined by clinical reasoning and patient education formats. A student who only practises older question styles may struggle with the newer format even if they know the drug content.
What was new in the 2025 NMCN pharmacology papers?
Magnesium sulphate for eclampsia — including toxicity signs and the antidote calcium gluconate — was the most notable addition. Tocolytic drugs and corticosteroids for fetal lung maturity also appeared more prominently than in previous years.
Are 2026 NMCN pharmacology questions available to practise?
Yes. FreshNote's question bank includes questions from the March 2026 Midwifery and May 2026 General Nursing sittings, accessible through the NMCN CBT practice platform.
How many pharmacology questions should I practise before the NMCN CBT?
There is no fixed number, but students who work through at least 200 to 300 pharmacology questions across multiple years before their sitting report significantly more comfort with the format. Quality of review matters as much as volume — every wrong answer should be fully understood before moving on.
Why does FreshNote have questions by year rather than just one big question pool?
Both options are available. Year-by-year study helps you understand how the exam has evolved. Mixed-pool practice — combining all years randomly — better simulates actual exam conditions where you do not know which year a question style is from. Use both.
What is the antidote for magnesium sulphate toxicity in NMCN exams?
Calcium gluconate given intravenously. This antidote pair first appeared prominently in 2025 papers and has continued into 2026. It is worth knowing alongside the full antidote list covered in the download guide linked above.
Final Note
Pharmacology is one of the few NMCN subjects where studying smarter genuinely beats studying harder. You do not need to memorise every drug in the British National Formulary. You need to know which drugs the NMCN keeps testing, in which formats, and across which years — then practise answering those specific question types until your responses are fast and accurate.
The year-by-year breakdown above gives you the roadmap. The question bank gives you the practice material. Put both together and pharmacology stops being the subject that catches you off guard.
Everything from 2012 to 2026 is on FreshNote's NMCN question bank. Work through it year by year, track your weak spots, and go into your CBT knowing you have seen every question pattern the examiners have used in the past six years.
