CNA Proper Hand Hygiene and PPE Usage 1 — Questions and Answers
Question 1: What is the minimum duration for scrubbing hands during hand hygiene?
- 10 seconds.
- 15 seconds.
- 20 seconds. (Correct answer)
- 30 seconds.
Correct answer: 20 seconds.
The Centers for Disease Control and Prevention (CDC) recommends scrubbing hands for at least 20 seconds during handwashing with soap and water. This duration ensures sufficient time to effectively dislodge and remove transient microorganisms from the skin surface. A shorter duration may not be adequate for proper infection control.
Question 2: When should a CNA change gloves during patient care?
- Only at the end of a shift.
- When moving between tasks or procedures. (Correct answer)
- Only if the gloves become visibly dirty.
- When the supervisor instructs to do so.
Correct answer: When moving between tasks or procedures.
Gloves should be changed when moving between different tasks or procedures, or when moving from a contaminated body site to a clean body site on the same patient. This practice prevents cross-contamination of microorganisms from one area to another. Changing gloves frequently is a critical step in maintaining aseptic technique and preventing the spread of infection.
Question 3: What is the first step when donning personal protective equipment (PPE)?
- Put on gloves.
- Perform hand hygiene. (Correct answer)
- Put on the gown.
- Secure the face mask.
Correct answer: Perform hand hygiene.
The first step in donning any personal protective equipment (PPE) is always to perform hand hygiene. This ensures that the hands are clean before touching and applying the PPE, preventing contamination of the clean equipment. Clean hands are fundamental to effective infection control practices and the safe use of PPE.
Question 4: What is the primary purpose of wearing a face mask in a healthcare setting?
- To reduce noise in the environment.
- To protect against the spread of droplets. (Correct answer)
- To keep the caregiver warm.
- To identify staff roles visually.
Correct answer: To protect against the spread of droplets.
The primary purpose of wearing a face mask in a healthcare setting is to protect against the spread of respiratory droplets. When a person coughs, sneezes, or talks, they can expel droplets containing pathogens. A mask acts as a barrier, preventing these droplets from reaching others or from being inhaled by the wearer, thus reducing the transmission of droplet-borne infections.
Question 5: How should a CNA remove a soiled gown after patient care?
- Pull it off quickly to save time.
- Fold it inward and dispose of it. (Correct answer)
- Shake it to remove debris before discarding.
- Reuse the gown if it looks clean.
Correct answer: Fold it inward and dispose of it.
When removing a soiled gown, it should be carefully folded inward so that the contaminated outer surface is contained. This minimizes the spread of pathogens to the environment or the healthcare worker's hands and clothing. The gown should then be immediately disposed of in the appropriate waste receptacle to maintain infection control.
Question 6: When should a CNA wear eye protection?
- Only when working with respiratory patients.
- During procedures involving splashing of fluids. (Correct answer)
- When instructed by a supervisor.
- Eye protection is optional.
Correct answer: During procedures involving splashing of fluids.
Eye protection, such as goggles or a face shield, is essential during procedures where there is a risk of splashes, sprays, or aerosols of blood, body fluids, secretions, or excretions. These fluids can carry pathogens that can enter the body through the mucous membranes of the eyes. Protecting the eyes prevents potential infection transmission and ensures caregiver safety.
