Biohazard And Needle-Stick Exposure Response - NCLEX Pn

1. In a hospital dialysis unit, an LPN sustains a needle-stick while disposing of a used needle after caring for a client with chronic hepatitis B infection (HBsAg positive); the LPN reports they never completed the hepatitis B vaccine series. Which step should the nurse take FIRST after the needle-stick injury?
   Answer: Wash the puncture site immediately with soap and water This question tests the immediate response to biohazard and needle-stick exposure from a known hepatitis B positive source in an unvaccinated nurse. The priority concern is immediate decontamination followed by urgent post-exposure prophylaxis. Washing the puncture site immediately with soap and water (A) is the best choice because it's the universal first step that reduces viral load at the exposure site. Requesting HBIG and vaccination (B) is critical but comes after immediate wound care, completing the incident report first (C) delays both wound care and medical intervention, and drawing baseline titers (D) before wound care inappropriately delays decontamination. The clinical judgment model emphasizes the correct sequence of interventions in high-risk exposures. The transferable strategy is: even in high-risk exposures requiring urgent prophylaxis, always perform immediate wound cleansing first, then pursue medical evaluation for time-sensitive interventions like HBIG.
2. In an outpatient clinic, an LPN experiences a splash of blood to the eyes while removing an IV from a client whose HIV status is unknown; the LPN is not wearing eye protection. What is the nurse's PRIORITY action following the exposure?
   Answer: Irrigate the eyes immediately with water or normal saline This question tests the immediate response to biohazard and needle-stick exposure, specifically mucous membrane exposure to blood. The priority concern is infection prevention through immediate decontamination of the exposed area. Irrigating the eyes immediately with water or normal saline (A) is the best choice because it dilutes and removes potentially infectious material from the mucous membranes, following standard exposure protocols. Calling the provider for HIV testing (B) is important but comes after immediate decontamination, applying alcohol-based hand rub to eyes (C) would cause severe irritation and is contraindicated for mucous membranes, and finishing the procedure first (D) delays critical decontamination and increases infection risk. The clinical judgment model emphasizes prioritizing actions based on immediate safety needs. The transferable strategy is: for any mucous membrane exposure, immediately flush with water or saline for at least 15 minutes before pursuing other interventions.
3. An LPN sustains a needle-stick while disposing of a used IV stylet after starting an IV under RN supervision. The source client is known to be HIV positive with an undetectable viral load. Which step should the nurse take FIRST after the needle-stick injury?
   Answer: Immediately wash the puncture site with soap and water This question tests the response to biohazard and needle-stick exposure. The priority concern is infection prevention despite the client's undetectable viral load, as risks still exist. Immediately washing the puncture site with soap and water is the best choice per standard protocols for initial decontamination. Reporting to the charge nurse (A) follows washing; asking for PEP (C) needs evaluation; reassuring no risk (D) is incorrect as follow-up is required. This follows the clinical judgment model by acting on exposure regardless of perceived low risk. The decision-making principle prioritizes self-decontamination first. A transferable strategy is to always wash needle-stick sites immediately, even with low-risk sources, and then follow post-exposure protocols.
4. An LPN in the ED is cleaning a blood spill when a splash hits the nurse's eye; the client's infection status is unknown. The nurse is wearing gloves but no face shield. What is the nurse's PRIORITY action following the exposure?
