AIDS Certified Registered Nurse (ACRN) Certification Practice Exam

PEP stands for Post-Exposure Prophylaxis, and it is specifically used after a potential exposure to HIV to prevent the virus from taking hold in the body. This is a critical intervention for individuals who have had a high-risk exposure, such as unprotected sexual contact with someone who is HIV positive, occupational exposure in healthcare settings, or sharing needles. PEP involves taking antiretroviral medications as soon as possible after the exposure—ideally within 72 hours. The treatment typically lasts for 28 days and is most effective when initiated promptly.

The other options do not accurately describe the term PEP in relation to its use in HIV prevention. The Periodic Evaluation of Patients refers to routine assessments that are not specific to HIV exposure and does not impact infection prevention. Pediatric Emergency Protocol would pertain to emergency procedures in children, rather than addressing post-exposure scenarios related to HIV. Lastly, a Public Education Program relates to awareness initiatives and education about HIV but is not connected to the medical intervention of preventing infection after an exposure incident.
