Read the first 7 CNA Infection Control & Prevention flashcards as text

  1. Which of the following best describes the purpose of surveillance cultures in a healthcare facility?

    Answer: To identify colonized individuals and monitor infection trends before outbreaks occur

    Surveillance cultures help detect colonization (e.g., MRSA) and track infection patterns to prevent outbreaks.

  2. A CNA is caring for a resident with active pulmonary tuberculosis (TB). Which respiratory protection is required?

    Answer: N95 respirator

    Active pulmonary TB requires airborne precautions, including a fit-tested N95 respirator, because TB bacilli travel on small airborne particles.

  3. The chain of infection includes a susceptible host. Which resident characteristic increases susceptibility to infection?

    Answer: Compromised immune system due to chemotherapy

    A compromised immune system reduces the body's defenses, making it easier for pathogens to establish infection.

  4. Which hand hygiene method is NOT effective against C. difficile spores?

    Answer: Alcohol-based hand rub (hand sanitizer)

    Alcohol-based hand rubs do not kill C. diff spores; soap and water with mechanical friction is required.

  5. A CNA accidentally splashes blood on their face. What is the correct immediate action?

    Answer: Flush the affected area with water immediately and report to the supervisor

    Splash exposures to mucous membranes require immediate flushing with water and prompt reporting for exposure evaluation.

  6. Which item in a patient's room is considered a high-touch surface requiring frequent disinfection?

    Answer: The call light button

    Call light buttons are touched frequently by patients and staff, making them high-touch surfaces that harbor pathogens.

  7. A CNA is assigned to care for a resident in airborne precautions. The CNA has not been fit-tested for an N95. What should they do?

    Answer: Inform the nurse and do not enter the room until properly fitted or reassigned

    An N95 respirator must be fit-tested before use; the CNA should notify the nurse and not enter until proper protection is available.
