16+ PNLE Infection Control & Safety Review Questions Study Guide

Introduction

I used to think Infection Control was “common sense.” Then I got wrecked by questions where two answers both looked safe, but only one followed the exact protocol. The PNLE is petty like that, in a good way, because real patients get harmed by tiny shortcuts.

In NP1, Infection Control and Safety usually shows up as, “What will you do first?”, “Which PPE is correct?”, “Which step breaks sterility?”, or “What teaching is accurate?” These are often easy to medium questions, but they’re easy only if you know the specific rules: clean to dirty, dry to wet, least contaminated to most contaminated, and what counts as a sterile field breach.

Students get tripped up when they memorize definitions but don’t visualize the actual sequence of actions. If you can picture your hands, your mask, your tray, your garbage bag, and the patient’s skin in real time, you’ll answer faster and with more confidence. Let’s make this the topic you stop losing “free points” on.

Key concepts

What to expect on the PNLE

Expect around 2 to 5 questions on Infection Control and Safety in a typical NP1 set, sometimes more because it overlaps with medication administration, vital signs, and basic skills. Most are clinical scenario questions with one “best” action, plus a few straight recall items on technique and timing.

The recurring scenarios are predictable. One, selecting PPE for a suspected infectious condition, especially respiratory. Two, identifying what action breaks sterile technique during dressing change or opening a sterile package. Three, community or bedside workflow like bag technique and proper disposal of contaminated supplies.

• Most common question pattern: “Which action by the nurse requires correction?” where 3 options sound safe, but one violates a rule like the 1-inch border, reaching over the field, recapping, or wrong hand hygiene method.
• What trap answers look like: Actions that are generally protective but not the priority, like “wear clean gloves” when the key issue is hand hygiene before gloving, or “clean the area” when the real issue is maintaining sterility.
• How to win: When torn, choose the option that prevents transmission at the source and follows sequence, hand hygiene, then barrier, then disposal. The PNLE rewards order and method.

Study tips

• Make a “PPE by mode of spread” mini-table tonight: On the left, write Airborne, Droplet, Contact. On the right, list exact PPE, room type, and key examples: TB/measles/varicella = N95 and negative pressure, flu/meningitis = surgical mask, MRSA/diarrhea wounds = gown and gloves. The PNLE rewards fast categorization, not long explanations.
• Memorize two hand hygiene rules that win points: Soap and water for visibly soiled hands and suspected spore-formers like C. difficile. Alcohol-based rub is great for routine decontamination when hands look clean. If you can say those without thinking, you avoid the most common “gotcha.”
• Visualize sterile field rules using the “WASH” mental model: Waist level, Away from moisture, Sight at all times, Hands sterile-to-sterile only. I made that mnemonic up, but it sticks, and it matches how PNLE asks “which action contaminates the field?”
• Act out PPE doffing once, literally: Pretend you’re removing gloves and gown without touching the outside, then eye protection, then mask, then hand hygiene. Your body memory helps on exam day because the options look similar and time pressure makes you doubt.
• Do 16 targeted questions in tangerine. and tag your misses: After every mistake, write one sentence: “I chose X because I forgot Y.” Patterns show up fast in Infection Control, and fixing two patterns can raise your score more than rereading notes.

Common mistakes to avoid

• “Alcohol rub solves everything”: You read a question with a nurse leaving a room after cleaning stool, and your gut says alcohol rub because it’s quick and common. But the PNLE wants soap and water when hands are visibly soiled or when spores are a concern, because rubbing doesn’t reliably remove spores. This one catches a lot of people because alcohol rub is pushed in posters everywhere.
• “I’ll recap to protect myself”: You imagine walking to the sharps container with an exposed needle and you feel nervous, so you pick “recap the needle” as the safest action. The PNLE wants immediate disposal in a puncture-proof sharps container, because recapping is a classic cause of needle-stick injuries. The trap answer sounds careful, but it adds a risky step.
• “My sterile gloves are on, so I can reach anywhere”: You see a scenario where the nurse reaches across the sterile field to grab gauze, and you think it’s fine because the nurse is wearing sterile gloves. The PNLE marks that as contamination because reaching over the field drops microorganisms from your gown/arms, and you lose sight control. They love this because it tests real sterile discipline, not just “wear gloves.”
• “Droplet and airborne are basically the same”: You see suspected SARS or a patient with cough and fever, and you pick surgical mask only because droplet is common for respiratory illness. The PNLE often frames severe respiratory syndromes as needing airborne-level protection like an N95/respirator plus eye protection depending on the scenario and facility protocol. The question is really testing if you can choose the higher-protection option when uncertainty is high.
• “Mantoux is just a shot, teach like any shot”: You pick teaching like “massage the area” or “cover it to keep it clean” because that’s what people do after injections. The PNLE wants: don’t scratch, don’t apply creams, don’t cover tightly, and return in 48 to 72 hours for reading. It’s not about comfort, it’s about accurate interpretation.
