Question 1: A resident has been placed on contact precautions. Which piece of PPE must you put on FIRST before entering the room?
- Gloves

Correct answer: Gown
The gown is donned first to protect clothing before putting on gloves, which are applied last.

- Mask, gloves, gown, hand hygiene
- Gown, gloves, mask, hand hygiene
- Gloves, gown, hand hygiene, mask
Correct answer: Gloves, gown, mask, hand hygiene
Gloves are removed first because they are the most contaminated item, followed by gown, then mask, with hand hygiene performed last.
Question 3: A CNA notices a needlestick injury after giving care. What is the FIRST action to take?
- Fill out an incident report
- Wash the site thoroughly with soap and water (Correct answer)
- Notify the charge nurse immediately
- Apply an antiseptic bandage
Correct answer: Wash the site thoroughly with soap and water
Immediately washing the wound with soap and water is the first step to reduce the risk of infection before reporting.
Question 4: Which organism is most commonly associated with healthcare-associated infections spread by the fecal-oral route?
- MRSA
- C. difficile (Correct answer)
- VRE
- Influenza A
Correct answer: C. difficile
Clostridioides difficile (C. diff) is spread via the fecal-oral route and requires soap-and-water handwashing rather than alcohol-based sanitizer.
Question 5: When caring for a resident with droplet precautions, the CNA must wear a surgical mask when:
- Entering the room regardless of distance
- Working within 3 feet of the resident (Correct answer)
- Only during procedures that produce aerosols
