- Surgical mask (Correct answer)
- Full face shield only
- No PPE needed
Correct answer: Surgical mask
Droplet precautions require a surgical mask worn within 3 feet of the patient.
Question 2: Which organism is the primary cause of healthcare-associated MRSA infections?
- Staphylococcus epidermidis
- Staphylococcus aureus (Correct answer)
- Streptococcus pyogenes
- Enterococcus faecalis

MRSA stands for methicillin-resistant Staphylococcus aureus, a common healthcare-associated pathogen.
Question 3: When performing hand hygiene with alcohol-based hand rub, how long should the nurse rub hands together?
- 5–10 seconds
- 15–20 seconds (Correct answer)
- 30–45 seconds
- 60 seconds
Correct answer: 15–20 seconds
The CDC recommends rubbing hands together for at least 15–20 seconds until dry when using ABHR.
Question 4: A nurse changes a dressing on a wound colonized with VRE. After removing gloves, the next action is to:
- Apply new gloves immediately
- Perform hand hygiene (Correct answer)
- Dispose of soiled dressing
- Document the procedure
Correct answer: Perform hand hygiene
Hand hygiene must be performed immediately after removing gloves to prevent organism transfer.
Question 5: Which isolation category requires a negative-pressure room?
- Contact precautions
- Droplet precautions
- Airborne precautions (Correct answer)
- Standard precautions
Correct answer: Airborne precautions
Airborne precautions require a negative-pressure (AIIR) room to prevent aerosolized particles from escaping.
Question 6: The nurse notices a tear in her glove while caring for a patient with Clostridioides difficile. The priority action is to:
- Finish the task then change gloves
- Apply a second glove over the torn one
- Remove the glove, perform hand hygiene, and reglove (Correct answer)
- Notify the charge nurse immediately
Correct answer: Remove the glove, perform hand hygiene, and reglove
A torn glove no longer provides a barrier; the nurse must remove it, perform hand hygiene, and apply a new glove.
Question 7: Which cleaning agent is most effective against Clostridioides difficile spores on environmental surfaces?
- Alcohol-based wipes
- Quaternary ammonium compounds
- Dilute bleach solution (Correct answer)
- Hydrogen peroxide spray
Correct answer: Dilute bleach solution
C. difficile spores are resistant to many disinfectants; EPA-registered hypochlorite (bleach) solutions are recommended.
