  1. Alcohol-based hand sanitizers are NOT effective against which organism and require soap and water instead?

    Answer: Clostridium difficile (C. diff) spores

    C. difficile produces spores with a protective coat impervious to alcohol; soap and water with mechanical friction is required to physically remove spores from hands.

  2. The CDC recommends scrubbing hands with soap and water for a minimum of:

    Answer: 20 seconds

    The CDC recommends lathering and scrubbing all hand surfaces for at least 20 seconds — approximately the time it takes to sing 'Happy Birthday' twice.

  3. To maximize the effectiveness of HIV post-exposure prophylaxis (PEP), it should ideally be initiated:

    Answer: Within 2 hours of exposure, but no later than 72 hours

    HIV PEP is most effective when started within 2 hours of exposure; after 72 hours it is generally not recommended as it is unlikely to prevent infection.

  4. HIV post-exposure prophylaxis (PEP) must be initiated within what maximum timeframe to be considered effective?

    Answer: 72 hours of exposure

    The CDC and OSHA guidelines state that HIV PEP must begin within 72 hours of a significant exposure; after this window it is not recommended.

  5. An employee who declines the employer-offered hepatitis B vaccine series must:

    Answer: Sign an OSHA-mandated declination statement

    OSHA requires a signed declination statement from any employee who chooses not to receive the HBV vaccine; this document must be retained by the employer.

  6. For a collector with a confirmed latex allergy, which glove material is the preferred substitute?

    Answer: Nitrile examination gloves

    Nitrile gloves are the preferred latex alternative because they provide superior puncture resistance, chemical barrier protection, and durability compared to vinyl.

  7. The primary purpose of maintaining the OSHA Sharps Injury Log is to:

    Answer: Record needlestick and sharps injury data to identify patterns and guide prevention

    The Sharps Injury Log helps employers analyze injury frequency, device type, and circumstance to evaluate safety programs and prioritize engineering control improvements.
