85+ PNLE Infection Control Nursing Questions Study Guide and Review Materials
Introduction
Infection control is that ninja skill you absolutely need to crush the PNLE. It's not just about reciting sterile techniques. It's about understanding how to break the chain of infection in a thousand different scenarios.
The PNLE is sneaky with this topic. Expect questions on everyday nursing tasks that, if done improperly, could spread infection. They're keen on testing your ability to prioritize steps in infection prevention and control scenarios.
Students often treat infection control as common sense. Big mistake. The exam tests specific protocols and taps into details that can trip you up. Hang tight, because we're diving into this topic headfirst.
Key concepts
What to expect on the PNLE
Expect 6-8 questions on infection control within a variety of contexts, mostly medium difficulty. They mix recall with clinical scenarios that test your application of preventive measures.
- Watch for clinical scenarios involving PPE use. You need to know the order like the back of your hand.
- Common scenario: Picking the right transmission-based precaution for common infections like tuberculosis (airborne) and MRSA (contact).
- Another favorite: Signs your IV line is going bad. Recognizing signs of phlebitis or infection is crucial.
- Trap answers often look right but miss the timing or sequence mark, like sterilizing too early or choosing the wrong precaution because it 'sounds right.'
Study tips
- Draw It Out: Create a quick sketch of the chain of infection and label each link. Visual aids can help you remember the process and points to intervene.
- PPE Sequence Mnemonic: Use "Gown, Mask, Goggles, Gloves" to memorize proper PPE donning. Reverse it for doffing: "Glasses, Gown, Mask." Own that sequence.
- Watch a Video on Sterile Technique: Seeing the steps in real-time can make the differences between sterile and clean techniques stick better.
- Create a Comparison Table: Compare and contrast transmission-based precautions with a table for contact, droplet, and airborne precautions. Focus on specific examples.
- Explain to a Friend: Can't find a friend? Talk to your reflection. Explaining how to prevent a specific infection consolidates your knowledge.
- Practice on tangerine.: Do questions that test infection control protocols, paying attention to rationales, which are where the real learning solidifies.
Common mistakes to avoid
- No Hand Hygiene Justification: You see a patient interaction in the question. Your gut says hand wash after every encounter. But you skip a crucial step when hands aren't visibly dirty, opting for hand sanitizer.
- PPE Order Confusion: You get a PPE sequence question. Intuition says gloves last in donning, first in doffing, yet you second-guess. The PNLE keys into this detail as one slip means missing the point.
- Mixing Precautions: You read about a measles patient assignment. Go for droplet precautions, thinking it’s the only respiratory route. Airborne, not droplet, is key here. It trips up many because they forget the specific pathogens associated.
- Ignoring Tiny Red Flags: You encounter a question on IV care. Think nothing of mild redness that escalates, so you choose monitoring as the action. But PNLE emphasizes vigilance even at early signs for intervention.

A real Infection Control question from our bank. Give it a shot.
Which of the following conditions is explicitly listed as a reason to prevent an individual from donating blood under the National Voluntary Blood Services guidelines?
Blood donor screening is designed to protect the recipient from transfusion transmitted infections and to protect the donor from harm. Under National Voluntary Blood Services style donor selection guidelines used in many blood programs, individuals with AIDS, syphilis, or other sexually transmitted diseases, past or present are explicitly listed as permanent or long term deferrals because these conditions are strongly associated with blood borne pathogens (especially HIV, hepatitis B, hepatitis C) and higher risk of window period infections. Even when a person feels well, pathogens can be present in the blood, and some infections can be asymptomatic for long periods. This makes a clear, safety focused exclusion necessary.
Key concept: donor eligibility is based on population risk and transmissibility, not only on the client’s current symptoms. Screening uses history, exam, hemoglobin testing, and infection risk questions. Laboratory testing reduces risk but does not eliminate it, so history based deferrals remain a cornerstone of safe blood supply.
| Option | Why it is correct or incorrect |
|---|---|
| A. Well controlled hypothyroidism | Incorrect. Stable, well controlled hypothyroidism (with no acute illness and acceptable hemoglobin) typically does not increase transfusion transmission risk. The main concern is donor safety, for example severe anemia, unstable cardiac disease, or acute systemic illness, not a stable endocrine condition. Donor centers may review medications and overall wellness, but hypothyroidism alone is not an explicit permanent deferral in standard guidelines. |
| B. Recent minor seasonal allergy | Incorrect. Minor allergies without systemic illness usually allow donation if the donor feels well, is afebrile, and is not experiencing significant respiratory compromise. Some centers defer if the client is actively symptomatic (sneezing, wheezing) or taking sedating medications, but a “recent minor seasonal allergy” is not an explicit disqualifier in core national guidelines. |
| C. Current pregnancy | Incorrect as stated for this question. Pregnancy is commonly a temporary deferral in many donor policies to protect the donor (maternal blood volume changes, iron requirements, risk of anemia) and fetus. However, the question asks for a condition explicitly listed as a reason to prevent donation under the referenced National Voluntary Blood Services guidelines, and the option set points to infectious risk exclusions. In exam logic, pregnancy is donor safety related and often time limited, whereas sexually transmitted infections are clearly emphasized as disqualifying due to recipient safety. |
| D. AIDS, syphilis, or other sexually transmitted diseases (past or present) | Correct. These diagnoses indicate high risk for transmissible infections through blood. Even treated infections can signal prior exposure and risk behaviors, and some pathogens may persist or be undetected during early infection. Therefore, guidelines explicitly list these as reasons to prevent blood donation to maintain a safe blood supply. |
Clinical pearl for board exams: When a question focuses on blood donation eligibility, prioritize answers that directly threaten recipient safety from transmissible disease, especially HIV and other infections linked with high risk blood exposure. Community health nursing emphasizes systems level protection, ensuring a safe blood supply is a population intervention, not just an individual assessment.
This question tests your ability to apply donor screening principles and choose the option that most clearly aligns with standard blood safety guidelines and transfusion transmitted infection prevention.

Practice questions
Q: A nurse is preparing to care for a patient with suspected tuberculosis. Which of the following precautions should the nurse implement?
Answer: C. Tuberculosis requires airborne precautions due to its high infectivity by air. Droplet precautions are often mistaken as sufficient, but they are inadequate for TB.
Q: During handwashing, when is using soap and water rather than alcohol sanitizer preferred?
Answer: A. Hands that are visibly dirty should be washed with soap and water. People often misjudge by assuming frequent sanitizer use is sufficient.
Q: A nurse is donning PPE for patient care. What should be the final step before entering the patient's room?
Answer: A. Putting on gloves is the last step when donning PPE. This order keeps the hands the most sterile for direct patient contact.
Q: Which of the following is a critical sign that necessitates the discontinuation of an IV line immediately?
Answer: C. Increased warmth and tenderness at an IV site suggest phlebitis or infection, requiring line discontinuation. Mild redness is overlooked when reading symptoms.
Q: For a patient with HIV receiving routine lab work, what precaution should be prioritized?
Answer: D. Standard precautions should be used for all patients, including those with HIV, to prevent bloodborne pathogen transmission.
