10+ PNLE Infection Control and Aseptic Technique Review Questions Study Guide and Review Materials
Introduction
I used to think infection control was just “wash your hands” and move on. Then the PNLE humbled me with questions about TB isolation, vaccine day logistics, and the weirdly specific rules of the PHN bag. This topic is where simple habits turn into points, because community health is all about preventing one case from becoming an outbreak.
On NP3, infection control shows up as practical scenarios. You’ll see TB clients at home, kids getting multiple EPI vaccines in one visit, disaster cleanup exposures, and documentation or reporting steps tied to communicable diseases. The exam isn’t impressed by fancy microbiology, it wants you to pick the safest, most standard public health action.
What trips people up is mixing up precautions, overusing PPE that isn’t needed, and forgetting that community health has workflows, like bag technique and routine inspections, that protect everyone. If you can mentally run a home visit and spot contamination risks like a hawk, you’re already scoring higher. Let’s lock in the stuff the PNLE actually asks.
Key concepts
What to expect on the PNLE
For NP3 Community Health, expect around 3 to 6 questions that touch infection control directly, and more that include it as part of a bigger scenario like immunization, TB follow-up, school health, or disasters. Most items are application-based, short clinical scenarios where you choose the best precaution, PPE, or nursing action. You’ll also see a few straightforward recall questions, like handwashing technique or the principle behind bag technique.
- Repeat scenarios: home visit for a coughing client with suspected/known TB, a child getting multiple EPI vaccines on the same day, and community exposure events like cleanup operations.
- Pattern that traps students: options that are all “correct” but not equally prioritized, like “health teaching about nutrition” versus “initiate airborne precautions and N95” in a TB situation.
- Trap answers look like: extra steps that sound thorough but break workflow or standards, like sterilizing everything in a home visit, using the wrong mask, or postponing vaccines without a contraindication.
If you can consistently pick the option that breaks transmission the fastest, protects the nurse and the community, and follows standard protocols, you’re answering like the board exam wants you to.
Study tips
- Make a “Precaution Match” table: Left column, **Airborne**, **Droplet**, **Contact**, **Standard**. Right column, list 3 examples each and the PPE, like TB equals Airborne plus **N95**, separate area, good ventilation. This directly trains you for those multiple-choice “what precaution” items.
- Memorize the TB combo you’ll actually use: Think “TB equals Air, Mask, Flow.” Airborne precautions, N95 for the nurse, and airflow or ventilation matters. If you can say that in 5 seconds, you’ll stop losing easy points.
- Practice the PHN bag sequence out loud: Literally narrate it, “clean surface, barrier, bag on barrier, take out only what I need, keep clean and dirty separated, hand hygiene, disinfect after.” It feels silly, but the PNLE loves “next step” logic, and narration makes your steps automatic.
- Use a 1-minute vaccine clinic drill: Ask yourself, “Can these vaccines be given today, and where do I inject?” Build the habit: multiple vaccines are usually okay, use different sites, document properly. Your goal is to prevent the knee-jerk answer of delaying.
- Do 9 targeted questions, then fix your weak pattern: Since you have limited items here, use tangerine. to spot your repeat mistake, like confusing surgical mask versus N95, or forgetting to protect the bag field. Do a second pass two days later to make sure it stuck.
Common mistakes to avoid
- Surgical mask for TB: You read the question, you see a coughing TB client at home. Your gut says “mask up” and you pick a surgical mask because it’s the common one and it feels like protection. But the PNLE wants **N95** for the healthcare worker with suspected or confirmed pulmonary TB because TB is airborne, and surgical masks do not filter airborne droplet nuclei well. This one catches a lot of people.
- Over-PPE instead of risk-based PPE: You see “cleanup” or “spill” and you want to choose the most intense PPE option because safety. But the PNLE wants hazard-specific protection, like gloves, boots, coveralls, and eye protection for splash and skin exposure, plus respiratory protection if fumes or aerosols are a risk. They’re testing judgment, not fear.
- PHN bag placed anywhere: You’re rushing in a home visit, the only surface is a chair or bed, so you put the bag down and start pulling supplies. It feels efficient and “nothing looks dirty.” But the PNLE wants you to create a barrier and maintain a clean field, because one contaminated bag turns you into a walking transmission route between houses.
- Delaying vaccines because “too many”: The child is due for multiple EPI vaccines, and you hesitate, thinking it’s safer to space them out. That sounds caring, but it increases missed opportunities and leaves the child vulnerable longer. The PNLE usually rewards same-day administration when indicated, using separate sites and correct technique.
- Hand hygiene only after: You focus on washing after care because that’s when your hands “feel dirty.” The PNLE wants you to protect the client too, so “before touching the client” and “before clean procedures” matters just as much. They’ll hide this inside a priority question where the best answer is boring but correct.
Try a question
A real Infection Control and Aseptic Technique question from our bank. Give it a shot.
Miss Kate is a bread vendor and you are buying a bread from her. You noticed that she receives and changes money and then holds the bread without washing her hand. As a nurse, what will you say to Miss Kate?
Choosing to ask Miss Kate to wash her hands before handling bread ("Miss, please wash your hands before you pick up those breads") directly addresses the fundamental principle of infection prevention. In community health, nurses are educators and advocates for safe food handling. The hands are the most common vectors for transmitting microorganisms to food, which can result in foodborne illnesses. According to public health nursing standards and guidelines, hand hygiene is the single most effective way to prevent the spread of infection, especially in food service settings.
By calmly and respectfully requesting handwashing, you promote health literacy and reinforce safe practices in a non-confrontational way. This approach aligns with the principles of therapeutic communication and health education emphasized in Public Health Nursing (White Book): nurses must empower individuals and communities to adopt safe, healthy behaviors.
Let's consider the other options:
| Option | Why It Is Incorrect |
|---|---|
| A. Miss, Don’t touch the bread I’ll be the one to pick it up | While this avoids contamination for you, it does not address the ongoing public health risk. It’s also not educational, other clients may be exposed, and there’s no improvement in Kate's practice. |
| C. Miss, Use a pick up forceps when picking up those breads | Although this is a valid method in some food settings, most small vendors may not have forceps available. The request is not practical unless such tools are accessible, and basic handwashing is the universal standard. |
| D. Miss, Your hands are dirty I guess I’ll try another bread shop | This response is confrontational and may cause embarrassment or resistance. It does not model professional or therapeutic communication expected from nurses, and fails to provide health education. |
Key Nursing Concepts and Clinical Reasoning
- Patient and community education is part of the nurse’s role in primary prevention.
- Hand hygiene is supported by the World Health Organization and CDC as a critical step in breaking the chain of infection.
- Communicating health advice should always be assertive yet respectful to encourage behavioral change and rapport.
Clinical Pearl: Remember the “Five Moments for Hand Hygiene” (before touching food, after touching money or contaminants, before eating, after bathroom use, and after coughing/sneezing) as a memory aid for when to perform handwashing in everyday and clinical settings.

A nurse is caring for a 42-year-old patient admitted with suspected infectious pulmonary tuberculosis (TB). The patient’s sputum smear is acid-fast bacilli (AFB) positive, and standard multidrug anti-TB therapy has been started. The patient asks when they will likely become less contagious if the medications are effective and taken as prescribed. Which response by the nurse is most appropriate?
Which statement about administering Expanded Program on Immunization (EPI) vaccines to children is correct?
A group of nurses is assigned to assist in the clean-up of a recent bunker oil spill. According to infection control and occupational safety guidelines, which combination of personal protective equipment (PPE) is MOST appropriate to minimize exposure to hazardous chemicals and fumes during this activity?
Practice questions
Q: A PHN visits a client with chronic cough and weight loss. The client is not yet diagnosed but TB is suspected. What is the most appropriate protection for the nurse during close contact assessment?
Answer: B. Suspected or confirmed pulmonary TB requires airborne precautions, and the nurse needs an N95 respirator for close contact. A surgical mask is mainly for droplet protection and for the client to reduce spread, not adequate protection for the nurse in airborne exposure. View more questions
Q: During a home visit, the only available surface to place the PHN bag is the family’s bed. What should the nurse do first to maintain asepsis?
Answer: B. The key principle of PHN bag technique is separating clean from contaminated surfaces using a barrier to maintain a clean field. Asking for bleach cleaning is unrealistic and delays care, and holding the bag increases handling and contamination risk. View more questions
Q: A school nurse performs rapid classroom inspections as part of communicable disease prevention. The goal is early detection and prompt control of outbreaks. Which action best supports this goal?
Answer: B. Rapid inspections work when done routinely with immediate reporting and action based on suspicion, not delayed until lab confirmation. Waiting for confirmation can allow transmission to continue, and focusing only on environmental cleanliness misses the main target, early case detection. View more questions
Q: A child is brought to the health center and is due for multiple EPI vaccines. The mother is worried the child will “get sick” if given more than one vaccine today. What is the best nursing response?
Answer: B. Community health practice avoids missed opportunities, and multiple indicated vaccines are commonly given in the same visit with correct technique, site selection, and documentation. Spacing them out without a contraindication increases the risk of incomplete immunization and preventable disease. View more questions
Q: A client with pulmonary TB has been on appropriate anti-TB medications for 2 weeks and reports less coughing and improved appetite. The family asks if they can stop infection precautions at home. What is the best answer?
Answer: C. Effective treatment usually reduces TB infectiousness over time, often around 2 to 3 weeks with improvement, but PNLE expects you to avoid absolute statements and emphasize following program guidance and clinical indicators. “Never contagious” and “contagious for life” are classic extreme options that look confident but are wrong.

Q: A community volunteer is assigned to help with cleanup after an oil spill. Which PPE set is most appropriate to reduce exposure during shoreline cleanup where splashes and skin contact are likely?
Answer: B. Oil spill cleanup is mainly a skin and splash exposure problem, so barriers for hands, body, feet, and eyes are key. An N95 alone misses the major risk, and sterile PPE is not the goal in field cleanup, protection is. View more questions
Q: A PHN is about to perform a clean procedure during a home visit. The nurse touched the client’s door handle and then prepared equipment on the clean field. What is the best immediate action?
Answer: B. The PNLE loves the boring truth: hand hygiene is required before clean procedures because you might transfer organisms from environmental surfaces to the client or supplies. Sterile gloves are not a substitute for hand hygiene, and disinfecting the whole room is unnecessary and unrealistic. View more questions
