All questions

Question 1

An LPN in the emergency department is cleaning a treatment room and is accidentally stuck by an uncapped needle left on the bedside table after a procedure; the source client is not immediately identifiable. What is the nurse's PRIORITY action following the exposure?

  1. Immediately wash the puncture site with soap and water (correct answer)
  2. Search the electronic record to identify the client before providing wound care
  3. Recap the needle and place it in the sharps container to prevent further injuries
  4. Wait to report the incident until the client is identified and lab results are available

Explanation: This question tests the immediate response to biohazard and needle-stick exposure from an unknown source. The priority concern is infection prevention through immediate wound care, regardless of source identification. Immediately washing the puncture site with soap and water (A) is the best choice because decontamination should never be delayed while trying to identify the source patient. Searching records before wound care (B) dangerously delays immediate decontamination, recapping the needle (C) violates safety protocols and could cause additional injury, and waiting to report until source identification (D) delays critical post-exposure interventions. The clinical judgment model emphasizes prioritizing immediate safety actions over information gathering. The transferable strategy is: treat all needle-stick injuries as potentially infectious and perform immediate wound care first, then work on source identification and reporting.

Question 2

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?

  1. Wash the puncture site immediately with soap and water (correct answer)
  2. Request an order for HBIG and hepatitis B vaccination to be given immediately
  3. Complete the incident report and then return to patient care
  4. Draw the nurse's blood for baseline hepatitis B titers before any other action

Explanation: 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.

Question 3

On a hospital unit, an LPN notices an overfilled sharps container with needles protruding above the fill line; the container is mounted in the medication room. What is the nurse's PRIORITY action?

  1. Use forceps to push the protruding needles down so the lid can close
  2. Close/lock the container if possible and replace it per facility policy using appropriate PPE (correct answer)
  3. Carry the container to the biohazard room to empty it into a larger container
  4. Document the issue in the unit log and address it at the end of the shift

Explanation: This question tests the response to biohazard and needle-stick exposure prevention through proper sharps container management. The priority concern is preventing needle-stick injuries from an overfilled container while maintaining safety protocols. Closing/locking the container if possible and replacing it per facility policy using appropriate PPE (B) is the best choice because it immediately addresses the hazard while following safe handling procedures.
