Infection control questions rarely arrive in NMCN practice papers as flat definitions. They come as short ward scenarios: a patient with a draining wound, a nurse about to insert a urinary catheter, a colleague who has just felt a needle prick. You are then asked what should happen next. Try free JUPEB past/practice question.
This page maps the formats those questions usually take, the wording cues that show which principle is being tested, and the mistakes students make when reading them too quickly. It describes question patterns only. It does not contain real or leaked NMCN questions, and it cannot promise what will appear in your paper. For the current syllabus, exam format and any official guidance, check with the Nursing and Midwifery Council of Nigeria (NMCN) directly.
Common Infection Control Question Stems
Most infection control items fall into a small number of families. Recognising the family is half the work, because each one wants a different kind of answer.
| Question family | Typical wording | What it is testing |
|---|---|---|
| First action | “What should the nurse do first?” | Order of priority, not the full care plan |
| Selection | “Which precaution is required?” or “Which PPE is appropriate?” | Matching the measure to the transmission route |
| Recognition of understanding | “Which statement by the student nurse shows understanding?” | Whether a principle is understood, not just memorised |
| Error spotting | “Which action indicates a break in technique?” | Fine detail inside a procedure |
| Negative stem | “Which of the following is NOT…” or “All except…” | Careful reading under time pressure |
Signal words matter. “First”, “immediately”, “initial” and “priority” push you toward the earliest safe action — usually stopping, cleaning hands, putting something on or taking it off, or moving the patient — rather than the definitive treatment. When a stem says “best”, it often asks you to choose between two options that are both technically correct, and the safer, more fundamental one wins.
Telling infection control apart from community health
These two areas overlap, and examiners know it. The reliable difference is the unit of concern. Community health questions ask about groups: a village, a school, a local government area, coverage of an immunisation drive, health education, record keeping. Infection control questions sit with one patient and one care setting: the route of transmission, whether a field is still sterile, which precaution notice goes on the door.
If the stem asks you to plan for a population, it is community health. If it asks what the nurse should do at the bedside, it is infection control. For how the paper mixes these areas overall, the companion guide to NMCN exam patterns covers the general structure; this page stays with infection prevention alone.
Hand Hygiene and PPE Question Formats
Hand hygiene questions are common in this section, and they usually test timing rather than technique: when hands must be cleaned, and what goes wrong if they are not.
Many items borrow the World Health Organization's framing of the moments when a health worker should clean their hands — before touching a patient, before a clean or aseptic procedure, after exposure to body fluids, after touching a patient, and after touching the patient's surroundings. Check the exact wording against current WHO guidance rather than a photocopied handout.
PPE items come in three shapes:
- Selection. “Which item of PPE is required for this task?” The distractors are usually items that protect the nurse in general but not against this particular exposure route.
- Sequence. Putting on and removing PPE in the right order. A commonly taught approach is gown first when putting on and gloves first when removing, with hand hygiene at the points your procedure manual states. Confirm the order your school teaches, because it is examined as a sequence.
- Failure. “The nurse removes gloves and then adjusts the mask. What is the problem?” These want you to name the contamination, not describe the whole procedure again.
Common mistakes in this section
Students lose marks by choosing the most elaborate precaution instead of the one that matches the task. A second error is answering “wash hands” when the stem assumes hands were already cleaned and asks about the next step. Read whether the scenario is at the start of the encounter or partway through it.
Isolation and Precautions Scenario Patterns
Standard precautions apply to every patient, whatever the diagnosis. Transmission-based precautions are added when a specific route is known or suspected, and that word “suspected” is the hinge of many questions.
Expect scenarios built around room placement, signage, visitor instructions and the moment precautions begin. The safe answer is almost always the one that starts precautions before laboratory confirmation. Notice, too, that the question is often not “what is the diagnosis” but “which precaution category does this presentation call for”.
Another pattern asks you to choose between two patients for a shared room, or to decide whether a patient can be moved. Answer from the transmission route, not from how unwell the patient looks. For current disease-specific precaution guidance, the Nigeria Centre for Disease Control and Prevention (NCDC) and your school's infection prevention policy are the places to check, since this detail is revised as guidance is updated.
Wording clues
“Until confirmed”, “on admission” and “before the result is available” all point in the same direction: act now. Stems that say “the nurse's best response is” usually want communication as much as technique — explaining to a patient or relative why a precaution is in place.
Sterile Technique and Procedure Questions
The procedures that appear most often are urinary catheterisation, wound dressing, intravenous cannulation and surgical hand scrub. These questions rarely ask you to describe the whole procedure. They ask about one moment inside it.
Three formats recur:
- Spotting the break. A short narrative describes what a nurse did, and you identify what contaminated the field. The answer is usually a small thing: turning away from the field, reaching over it, letting a sterile item touch an unsterile surface, or a glove brushing the trolley edge.
- Ordering. The steps are listed out of order and you arrange them. Anchor the sequence on when the sterile field is created and when it is covered.
- Correct recovery. “The nurse notices the catheter touched the bed. What should she do?” The answer is to stop and start again with new equipment — not to clean the item and carry on.
A useful revision habit: for each procedure, write down the single action that would ruin sterility. That is the kind of detail these questions tend to target.
Safety and Waste Management Clues
Safety items mix infection control with general ward safety, which is why they can feel unpredictable. The themes are consistent, though: sharps, segregation, spills and exposure incidents.
Segregation questions ask you to place a particular item in the right waste stream. Colour coding is where students get caught, because schemes differ between facilities and have changed over time. Learn the principle — sharps go into a puncture-resistant container, and infectious waste is separated from general waste where it is generated — then check the colour system your school and clinical area actually use, rather than trusting a colour from a textbook written for another country.
Exposure questions follow a sequence. After a needle-stick injury the expected pattern is to deal with the wound site as your protocol directs, report the incident promptly, and follow the facility's post-exposure procedure. This page deliberately gives no drug details, because post-exposure management is clinical policy and belongs to your facility's protocol and current national guidance.
Spill questions test order of operations: protect yourself, contain, clean according to policy, then dispose correctly. An option that tells you to leave the spill uncovered while you fetch a colleague is there to be rejected.
The strongest way to prepare for this section is to take each principle above and turn it into a “first action” question of your own, then answer it out loud. If you can explain why the other three options fail, you have understood the format well enough to handle unfamiliar wording on the day. For everything time-sensitive — the current syllabus, exam structure and any formal guidance — rely on NMCN and your school, not on a summary page.
