CNA - Certified Nursing Assistant Infection Control and Safety 1

Question 1

A CNA notices that a resident's wound dressing is saturated and needs to be changed. Before beginning the procedure, which action should the CNA perform first?

Accepted Answer

Perform hand hygiene and gather all necessary supplies

Answer

Hand hygiene must be performed before any procedure to prevent the transfer of pathogens. Gathering supplies beforehand also prevents the CNA from contaminating surfaces or leaving the resident mid-procedure, both of which are infection control and safety priorities.

Question 2

A CNA is caring for a resident placed on airborne precautions due to active pulmonary tuberculosis. Which personal protective equipment (PPE) must the CNA wear before entering the room?

Accepted Answer

N95 respirator and gown

Answer

Airborne precautions for TB require an N95 respirator (not a standard surgical mask) because TB particles are small enough to remain suspended in air. A gown is also required to protect clothing from contamination during direct care.

Question 3

A CNA has just removed gloves after assisting a resident with toileting. What is the correct next step?

Accepted Answer

Perform hand hygiene immediately after glove removal

Answer

Gloves can have small, invisible tears and hands can become contaminated during removal. Performing hand hygiene immediately after glove removal is a fundamental infection control standard that prevents the spread of microorganisms.

Question 4

During morning rounds, a CNA notices a spill of body fluid on the floor near a resident's bed. What is the safest and most appropriate immediate action?

Accepted Answer

Don gloves, clean the spill, and apply a facility-approved disinfectant to the area

Answer

Body fluid spills require prompt cleaning with appropriate PPE (at minimum, gloves) and disinfection with a facility-approved solution. Leaving the spill unattended creates a fall and infection risk, and bare-hand contact is never acceptable.

Question 5

A CNA is preparing to use a blood pressure cuff that was previously used by a resident on contact precautions. What should the CNA do before using it on another resident?

Accepted Answer

Disinfect the cuff with a facility-approved disinfectant wipe and allow it to dry

Answer

Equipment used on a resident in contact precautions must be thoroughly disinfected with an approved disinfectant before use on another resident. Allowing drying time ensures the disinfectant has adequate contact time to kill pathogens.
