CNA Isolation Precautions 4 — Questions and Answers
Question 1: A patient is on Contact Precautions. When the CNA enters the room to assist with a bed bath, which PPE must be worn?
- Gown and gloves only (Correct answer)
- Mask and gloves only
- Gown, gloves, and N95 respirator
- No PPE is required for routine care
Correct answer: Gown and gloves only
Contact Precautions require a gown and gloves before entering the room to prevent spread of organisms transmitted by direct or indirect contact.
Question 2: Which of the following diseases requires Airborne Precautions?
- MRSA
- Tuberculosis (TB) (Correct answer)
- Influenza
- Clostridium difficile (C. diff)
Correct answer: Tuberculosis (TB)
Tuberculosis is transmitted via airborne droplet nuclei that remain suspended in the air and requires an Airborne Precautions room with negative pressure ventilation.
Question 3: A CNA is caring for a patient in Droplet Precautions. The patient asks for a glass of water. Which PPE is required?
- N95 respirator and face shield
- Surgical mask and eye protection (Correct answer)
- Gown and gloves only
- No PPE if staying more than 3 feet away
Correct answer: Surgical mask and eye protection
Droplet Precautions require a surgical mask and eye protection when within 3 feet of the patient to protect against large respiratory droplets.
Question 4: After leaving an isolation room, the CNA should remove PPE in which order?
- Mask, gloves, gown, hand hygiene
- Gloves, gown, mask or respirator, hand hygiene (Correct answer)
- Gown, mask, gloves, hand hygiene
- Hand hygiene, gloves, gown, mask
Correct answer: Gloves, gown, mask or respirator, hand hygiene
The CDC recommends removing gloves first, then gown, then mask or respirator, followed by hand hygiene to minimize self-contamination.
Question 5: A patient with C. diff (Clostridium difficile) is on Contact Precautions. Which hand hygiene product is most effective against C. diff spores?
- Alcohol-based hand sanitizer
- Soap and water (Correct answer)
- Antimicrobial foam
- Antiseptic wipes
Correct answer: Soap and water
C. diff spores are NOT killed by alcohol-based sanitizers; soap and water must be used because the friction physically removes the spores.
Question 6: Which type of isolation room has air pressure that is lower inside than in the hallway?
- Protective environment room
- Positive pressure room
- Negative pressure room (Correct answer)
- Standard private room
Correct answer: Negative pressure room
Negative pressure (airborne infection isolation) rooms pull air inward so contaminated air cannot escape into the hallway, used for Airborne Precautions.
Question 7: A patient has chickenpox. A CNA who has never had chickenpox or been vaccinated should:
- Wear a surgical mask and enter the room
- Wear a gown and gloves only
- Not enter the room and notify the nurse (Correct answer)
- Use Standard Precautions only
Correct answer: Not enter the room and notify the nurse
Susceptible healthcare workers should not care for patients with varicella (chickenpox) because it is highly contagious via airborne and contact routes.
