  1. Which of the following is an example of a fomite in disease transmission?

    Answer: A contaminated stethoscope

    A fomite is an inanimate object that can harbor and transfer pathogens; a contaminated stethoscope is a classic example in healthcare settings.

  2. When using an alcohol-based hand rub, how long should rubbing continue?

    Answer: Until hands feel dry (approximately 15–20 seconds)

    Alcohol-based hand rubs should be rubbed into all hand surfaces until hands are dry, which takes approximately 15–20 seconds for proper antimicrobial action.

  3. Which type of waste container must be used for disposal of a lancet after a fingerstick blood glucose test?

    Answer: Sharps container

    Lancets are sharps and must be disposed of directly into a puncture-resistant sharps container immediately after use to prevent needlestick injuries.

  4. The chain of infection includes six links. Which link represents the mode of transmission?

    Answer: Means by which the pathogen travels from reservoir to host

    The mode of transmission is the means by which a pathogen travels from its reservoir to a susceptible host, such as direct contact, droplets, or airborne spread.

  5. A patient with Clostridium difficile (C. diff) infection requires which type of precautions?

    Answer: Contact precautions with soap-and-water hand hygiene

    C. difficile requires contact precautions, and alcohol-based hand rubs are ineffective against its spores, so soap and water hand washing is mandatory.

  6. What does the acronym 'RACE' stand for in fire emergency response?

    Answer: Remove, Alarm, Contain, Extinguish

    RACE stands for Remove patients from danger, Alarm (activate fire alarm), Contain the fire by closing doors, and Extinguish if safely possible.

  7. Which disinfectant level is required to process semi-critical medical devices such as endoscopes?

    Answer: High-level disinfection

    Semi-critical devices that contact mucous membranes require high-level disinfection to eliminate all microorganisms except high numbers of bacterial spores.
