1. A

   Hepatitis B

2. B

   Hepatitis C

3. C

   Tetanus

4. D

   HIV

Appeared in: NORCET -4 , 2023

Explanation

Listen in Hindi

• There is no vaccine or immune globulin available for post-exposure prophylaxis (PEP) against the Hepatitis C virus (HCV).
• The standard management for a potential HCV exposure is to perform baseline testing on the exposed individual and the source patient.
• The exposed individual is then monitored with follow-up testing (e.g., HCV-RNA test) to detect seroconversion.
• If infection is confirmed, early antiviral treatment is initiated to prevent chronic infection.

Why Other Options Were Wrong

• Option A: PEP is available and recommended for Hepatitis B exposure. It is a standard protocol.
• Option C: A needlestick is a puncture wound. Tetanus prophylaxis (Td or Tdap vaccine) is required if the person's vaccination history is not current (e.g., booster within the last 10 years).
• Option D: PEP is strongly recommended for significant HIV exposure. A 28-day course of antiretroviral therapy should be started as soon as possible.

Clinical Relevance

• Nursing practice connection: Knowing Post-Exposure Prophylaxis (PEP) following needlestick injury helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
• Immediate reporting of any needlestick injury is critical. This allows for timely risk assessment and initiation of PEP if indicated, which can significantly reduce the risk of infection.
• Nurses must be aware of their institution's specific policies and procedures for managing occupational exposures, including who to contact and where to go for immediate evaluation.
• What if the source patient is unknown or refuses testing? In this situation, the decision to offer PEP is based on the type of exposure and the prevalence of bloodborne diseases in the patient population. The exposed healthcare worker is managed as if the exposure was high-risk.

How to Approach the Question

• First, identify the core of the question: it's about post-exposure prophylaxis (PEP) after a needlestick injury.
• Note the critical negative keyword: 'NOT required'. This means you are looking for the one disease in the options for which PEP is unavailable or not standard practice.
• Systematically review each option based on your knowledge of common bloodborne pathogens and wound management.
• Recall the PEP protocol for Hepatitis B (vaccine/HBIG), HIV (antiretrovirals), and Tetanus (booster for puncture wounds).
• Identify Hepatitis C as the exception for which no immediate prophylactic vaccine or medication is given post-exposure. The protocol is monitoring and treatment if infection occurs.
• Select the option that matches this exception.
