CNA CNA Infection Control & Prevention

Question 1

What type of transmission precaution requires a CNA to wear a gown, gloves, and limit the patient's transport outside the room?

Accepted Answer

Contact precautions

Answer

Contact precautions are used for infections spread by direct or indirect contact (e.g., MRSA, C. diff) and require gloves and gown upon room entry and limiting patient transport.

Question 2

Which disease requires airborne precautions, meaning a CNA must wear an N95 respirator?

Accepted Answer

Active pulmonary tuberculosis (TB)

Answer

Active pulmonary tuberculosis spreads via airborne droplet nuclei that remain suspended in air, requiring an N95 respirator rated to filter particles ≥0.3 microns.

Question 3

When removing personal protective equipment (PPE), which item should a CNA remove first?

Accepted Answer

Gloves

Answer

Gloves are considered the most contaminated item and should be removed first using a glove-to-glove, skin-to-skin technique to prevent self-contamination.

Question 4

A patient is diagnosed with Clostridium difficile (C. diff). Which hand hygiene method is most effective against C. diff spores?

Accepted Answer

Soap and water for at least 20 seconds

Answer

C. diff forms spores that are NOT killed by alcohol-based hand sanitizers; soap and water physically removes spores from the hands and is required for C. diff.

Question 5

Standard precautions in healthcare require a CNA to treat which body fluids as potentially infectious?

Accepted Answer

Blood, all body fluids, secretions, and excretions (except sweat)

Answer

Standard precautions apply to blood, all body fluids (except sweat), non-intact skin, and mucous membranes, regardless of a patient's known infection status.
