What will you do if you have a needle stick injury from an HIV patient?

Appeared in: NORCET 1 - 2020

Explanation

  • The immediate and correct first-aid measure for a needlestick injury is to wash the exposed site thoroughly with soap and running water.
  • This action helps to mechanically remove surface contaminants, including the virus, from the wound site.
  • It is a non-invasive method that cleans the wound without causing additional tissue trauma, which could potentially increase viral absorption.
  • This is the universally recommended first step in all guidelines for managing occupational exposures to blood-borne pathogens.

Why Other Options Were Wrong

  • Option A: Making an incision into the wound is contraindicated. It causes further tissue damage, increases bleeding, and can facilitate deeper entry of the virus into the bloodstream, thereby increasing the risk of infection.
  • Option B: Sucking the blood from the wound is dangerous. It exposes the mucous membranes of the mouth to the patient's blood, creating a new and significant risk of HIV transmission to the healthcare worker.
  • Option C: Squeezing or 'milking' the wound is not recommended. This action can cause micro-trauma to the surrounding tissues, which may paradoxically increase the absorption of the virus into the local blood vessels rather than expelling it.

Clinical Relevance
  • Nursing practice connection: Use the key finding related to First aid and post-exposure prophylaxis for needlestick injury to guide bedside assessment, documentation, and the next nursing action.
  • Immediate and correct first aid is critical in minimizing the risk of occupational transmission of HIV, which is estimated at about 0.23% per percutaneous exposure.
  • All healthcare workers must be trained in the post-exposure prophylaxis (PEP) protocol, which includes immediate reporting, source and worker testing, and timely initiation of antiretroviral drugs (ideally within 2 hours).
  • What if the source patient's HIV status is unknown? The protocol remains the same. First aid is administered, and the source patient should be tested for HIV, HBV, and HCV as quickly as possible after obtaining consent. PEP may be initiated pending test results, especially if the source has risk factors for HIV.
How to Approach the Question
  • First, identify the question as a safety and procedure-based question concerning an occupational hazard.
  • Recall the fundamental principles of first aid, particularly for puncture wounds involving potential pathogens. The primary goal is to clean the area and 'do no harm'.
  • Evaluate each option based on this principle.
  • Eliminate 'Give incision to the injury' as it is invasive and harmful.
  • Eliminate 'Suck out the blood' as it creates a new exposure route.
  • Eliminate 'Squeeze out the blood' as it can cause tissue trauma and increase absorption.
Concept Tested & Keywords
  • Concept Tested: First aid and post-exposure prophylaxis for needlestick injury.
  • Stem keywords: needlestick injury, HIV patient
  • Lead-in keywords: What will you do
  • Clinical cues: Exposure to blood from an HIV-positive patient, which is a high-risk situation requiring immediate and correct action.
