CPCA Infection Control & Safety Procedures 2 — Questions and Answers
Question 1: A client has C. difficile (C. diff). Which type of isolation precautions should the aide follow?
- Airborne precautions
- Contact precautions (Correct answer)
- Droplet precautions
- Standard precautions only
Correct answer: Contact precautions
C. diff spreads via fecal-oral contact with spores, requiring contact precautions including gown and gloves.
Question 2: Which disinfectant is most effective against C. difficile spores in a client's environment?
- Isopropyl alcohol 70%
- Quaternary ammonium compounds
- Bleach solution (sodium hypochlorite) (Correct answer)
- Hydrogen peroxide spray
Correct answer: Bleach solution (sodium hypochlorite)
Bleach (sodium hypochlorite) is the recommended disinfectant for killing C. diff spores; alcohol-based products are ineffective.
Question 3: After removing gloves, the aide should:
- Rinse gloves and reuse them if they appear clean
- Perform hand hygiene immediately (Correct answer)
- Apply lotion before washing hands
- Use gloves again if only worn briefly
Correct answer: Perform hand hygiene immediately
Hands must be cleaned immediately after removing gloves because gloves can have small unseen holes and hands may become contaminated.
Question 4: A client with MRSA has a wound on their arm. What PPE is required when changing the dressing?
- Mask and eye protection only
- Gloves only
- Gloves and gown (Correct answer)
- No PPE needed if hands are washed
Correct answer: Gloves and gown
MRSA wound care requires both gloves and a gown to prevent contact transmission to the aide's clothing and skin.
Question 5: The correct sequence for donning (putting on) PPE is:
- Gloves → gown → mask → eye protection
- Gown → mask → eye protection → gloves (Correct answer)
- Mask → gloves → gown → eye protection
- Eye protection → gloves → mask → gown
Correct answer: Gown → mask → eye protection → gloves
The CDC-recommended donning order is gown first, then mask/respirator, then eye protection, then gloves.
Question 6: An aide notices the sharps container in a client's home is three-quarters full. What should the aide do?
- Continue using it until completely full
- Request a replacement container before it reaches the fill line (Correct answer)
- Empty and clean the container for reuse
- Transfer sharps to a plastic bag temporarily
Correct answer: Request a replacement container before it reaches the fill line
Sharps containers should be replaced when they reach the manufacturer's fill line (usually 3/4 full) to prevent needlestick injuries.
Question 7: What is the primary purpose of using a gait belt when transferring a client?
- To restrict the client's movement during transfer
- To provide a secure grip and reduce injury risk for both client and aide (Correct answer)
- To replace the need for a mechanical lift
- To monitor the client's weight during transfer
Correct answer: To provide a secure grip and reduce injury risk for both client and aide
A gait belt provides a stable, secure handhold around the client's waist, reducing the risk of falls and back injury during transfers.
