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.

At a Philippine blood-donation center, which candidate has a current finding that independently requires deferral at today’s screening?
Blood donation centers adhere strictly to eligibility criteria to ensure donor safety and the safety of blood recipients. These criteria screen for health risks that could make blood donation hazardous for the donor or compromise the quality of the donated blood. Pregnancy is an absolute contraindication for blood donation because of the physiological demands placed on the mother and the risks to the fetus. Other factors such as current health status, weight, vital signs, and chronic illness management are also assessed but may not independently preclude donation if they meet established thresholds and no other contraindications exist.
Why the correct option is correct
Option B is correct because pregnancy independently requires immediate deferral from blood donation, regardless of how the candidate feels or the absence of acute symptoms. Blood donation during pregnancy increases risks of anemia, hypovolemia, or fetal compromise due to reduced maternal blood reserve. Philippine and international guidelines explicitly mandate that pregnant women must not donate blood at any point during pregnancy, making this an automatic and non-negotiable deferral at screening.
Clinical pearl: Pregnancy is always a direct exclusion for blood donation, independent of gestational age or maternal well-being.
Why the other options are incorrect
| Option | Why it is wrong |
|---|---|
| A | Candidates over 50 kg, with normal temperature and pulse, and acceptable hemoglobin, meet basic donation criteria and have no current finding that requires today’s deferral. |
| C | Treated hypertension is allowed if the candidate’s blood pressure does not exceed center-specific thresholds and the medical exam is passed, so there is no independent reason for automatic deferral today. |
| D | No abnormal finding or exclusion is described; candidates in good health, after a meal and rest, who pass screening, are eligible for donation. |
Nursing concepts and clinical reasoning
- Assess each candidate for absolute and relative contraindications, prioritizing maternal and fetal safety
- Rapidly identify findings that require automatic exclusion, such as pregnancy, recent infection, severe anemia, or high-risk behaviors
- Recognize that well-controlled chronic conditions (e.g., hypertension) may not automatically preclude donation if they pass screening
- Act as patient advocates by preventing at-risk individuals from donating
- Document and explain reasons for deferral in a supportive and nonjudgmental manner
Focus of the question
This question tests the nurse’s ability to identify specific clinical scenarios where a candidate must be deferred from blood donation based on current findings, emphasizing knowledge of absolute contraindications such as pregnancy.

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.
