A. Wearing sterile gloves only
B. Using sterile drapes and maintaining a sterile field
C. Cleaning the site with alcohol in a circular motion from the outside in
D. Opening sterile supplies before donning sterile gloves
Answer: B. Using sterile drapes and maintaining a sterile field
Rationale: Surgical aseptic technique (sterile technique) requires a sterile field,
sterile drapes, and sterile gloves. Cleaning should be from the inside out. Supplies
should be opened after donning sterile gloves to maintain sterility.
2. A client with tuberculosis is placed on airborne precautions. Which PPE is
essential when entering the room?
A. Surgical mask and gloves
B. N95 respirator and gloves

Rationale: Airborne precautions (TB, measles, varicella) require an N95 respirator.
Gloves are always worn if contact with body fluids is possible.
3. The nurse is caring for a client with Clostridioides difficile. Which hand hygiene
method is correct?
A. Alcohol-based hand rub only
B. Soap and water for at least 15 seconds
C. Soap and water because alcohol does not kill C. diff spores
D. Hand sanitizer followed by soap and water

Rationale: Proper fit prevents circulatory/nerve damage. Restraints require an
order before application in non-emergencies (or within 1 hour for emergencies),
never tie to side rails, and document q1-2h.

, A. Client with pneumonia
B. Client undergoing allogeneic stem cell transplant
C. Client with MRSA wound infection
