CNA Infection Control 4 — Questions and Answers
Question 1: A resident has been placed on contact precautions. Which PPE must you put on BEFORE entering the room?
- Gown and gloves (Correct answer)
- Mask and gloves
- Gown and mask
- Gloves only
Correct answer: Gown and gloves
Contact precautions require a gown and gloves to be donned before entering the room to prevent transmission via direct or indirect contact.
Question 2: Which of the following is an example of a vector-borne transmission of infection?
- A mosquito bite transmitting West Nile virus (Correct answer)
- Touching a contaminated doorknob
- Inhaling droplets from a sneeze
- Eating undercooked chicken
Correct answer: A mosquito bite transmitting West Nile virus
Vector-borne transmission occurs when a living organism such as a mosquito carries and transmits a pathogen to a host.
Question 3: When removing contaminated gloves, what is the correct first step?
- Pinch the outside of one glove near the wrist and pull it off (Correct answer)
- Pull both gloves off at the same time
- Rinse gloves under water before removing
- Remove the glove from the dominant hand first by touching the inside
Correct answer: Pinch the outside of one glove near the wrist and pull it off
The correct technique is to pinch the outside of one glove near the wrist and pull it off to avoid touching the contaminated outer surface with bare skin.
Question 4: A CNA notices a co-worker does not perform hand hygiene after removing gloves. The CNA should:
- Remind the co-worker that hand hygiene is required after glove removal (Correct answer)
- Ignore it since gloves protect against contamination
- Report it only if a resident becomes ill
- Perform hand hygiene for both themselves and the co-worker
Correct answer: Remind the co-worker that hand hygiene is required after glove removal
Gloves can have micro-tears and hands become contaminated during removal, so hand hygiene after glove removal is mandatory and co-workers should be reminded.
Question 5: Which infection control practice helps prevent the spread of C. difficile (C. diff)?
- Washing hands with soap and water instead of alcohol-based sanitizer (Correct answer)
- Using alcohol-based hand sanitizer exclusively
- Wearing only gloves without a gown
- Placing the resident on airborne precautions
Correct answer: Washing hands with soap and water instead of alcohol-based sanitizer
C. difficile spores are not killed by alcohol-based hand sanitizers, so soap and water handwashing is required to physically remove the spores.
Question 6: What does the term 'nosocomial infection' mean?
- An infection acquired in a healthcare setting (Correct answer)
- An infection that cannot be treated with antibiotics
- An infection present before admission
- An infection transmitted by insects
Correct answer: An infection acquired in a healthcare setting
A nosocomial infection, also called a healthcare-associated infection (HAI), is one that a patient acquires while receiving care in a healthcare facility.
Question 7: Which item is considered a fomite in infection control?
- A contaminated stethoscope (Correct answer)
- A healthcare worker's hands
- Airborne droplet nuclei
- A mosquito
Correct answer: A contaminated stethoscope
A fomite is an inanimate object that can carry and transfer infectious organisms, such as a contaminated stethoscope, bedside table, or call light.
A resident has been placed on contact precautions.
