- Droplet precautions
- Contact precautions (Correct answer)

C. diff is spread by contact with contaminated surfaces and feces, so contact precautions are required.
Question 2: When removing PPE after caring for a patient on contact precautions, what is removed FIRST?

- Gloves (Correct answer)
- Gown
- Goggles
Correct answer: Gloves
Gloves are removed first because they are the most contaminated item of PPE.

- Touching the outside of both gloves with bare hands to pull them on
- Using the inner cuff of the first glove to put it on, then sliding gloved fingers under the cuff of the second (Correct answer)
- Putting on gloves before performing hand hygiene
- Holding gloves by the fingers to shake them open
Correct answer: Using the inner cuff of the first glove to put it on, then sliding gloved fingers under the cuff of the second
Sterile technique requires touching only the inner cuff of the first glove and using the sterile gloved hand to don the second.
Question 4: A CNA notices a small tear in their glove mid-procedure. What should they do?

- Sneezing near a patient
- Contaminated food causing foodborne illness (Correct answer)
- A mosquito bite transmitting a pathogen

Vehicle transmission occurs through contaminated food, water, or blood products.

Sharps must be placed directly into an approved sharps container immediately after use without recapping to prevent needlestick injuries.

A surgical mask is required for droplet precautions when within 3 feet of the patient, as droplets do not travel far.
