  1. What is the recommended sequence for donning (putting on) PPE in a healthcare setting?

    Answer: Gown → mask/respirator → eye protection → gloves

    The CDC recommends donning gown first, then mask or respirator, then eye protection, and finally gloves so each layer protects the previous one.

  2. Which bloodborne pathogen has the highest risk of transmission following a needle-stick injury?

    Answer: Hepatitis B virus (HBV)

    Hepatitis B virus has a transmission risk of up to 30% after a needle-stick from a HBeAg-positive source, far higher than HIV or HCV.

  3. In the laboratory, when must gloves be changed?

    Answer: After every patient specimen and when contaminated

    Gloves must be changed between patients and whenever they become contaminated to prevent cross-contamination of specimens and surfaces.

  4. Which of the following is classified as an OPIM (Other Potentially Infectious Material) under OSHA's Bloodborne Pathogen Standard?

    Answer: Cerebrospinal fluid

    Cerebrospinal fluid is specifically listed as an OPIM under OSHA's Bloodborne Pathogen Standard along with semen, vaginal secretions, and other body fluids.

  5. A phlebotomist sustains a needle-stick injury from a patient of unknown HIV status. What is the FIRST step in post-exposure management?

    Answer: Wash the wound with soap and water and report the exposure

    The immediate priority after a needle-stick is to wash the wound thoroughly and report the incident so a post-exposure protocol can be initiated.

  6. Which of the following pathogens requires droplet precautions?

    Answer: Influenza

    Influenza is transmitted by large respiratory droplets and therefore requires droplet precautions, including a surgical mask within 3 feet of the patient.

  7. What is the recommended disinfection level for non-critical patient care items that contact only intact skin?

    Answer: Low-level disinfection

    Non-critical items such as blood pressure cuffs require only low-level disinfection because they contact only intact skin and pose minimal infection risk.
