| Nursing Fundamentals
1. A nurse is caring for a client with Clostridioides difficile.
Which type of isolation is most appropriate?
A. Droplet precautions
B. Airborne precautions
C. Contact precautions
D. Protective environment
Answer: C
Rationale: C. diff spreads via direct contact with feces or
contaminated surfaces. Contact precautions (gown +
gloves, private room, dedicated equipment) prevent
transmission. Droplet (A) is for large respiratory droplets
(flu, rubella). Airborne (B) is for small particles (TB,
measles). Protective (D) is for immunocompromised hosts.
2. A client is placed on airborne precautions for
suspected tuberculosis. Which PPE is essential when
entering the room?
1
,A. Surgical mask
B. N95 respirator
C. Gown and gloves only
D. Face shield
Answer: B
Rationale: Airborne precautions require an N95 (or
higher) respirator to filter 95% of small airborne
particles. Surgical masks (A) protect only from large
droplets. Gown/gloves (C) alone do not prevent
inhalation. Face shield (D) protects mucous membranes
only.
3. Which is the correct order for donning PPE?
A. Gown → mask → goggles → gloves
B. Gloves → gown → mask → goggles
C. Mask → goggles → gown → gloves
D. Goggles → mask → gown → gloves
Answer: A
Rationale: Don in this sequence: gown (protects clothing),
2
,mask (protects airway), goggles (eye protection), then
gloves (last, to protect hands after other PPE is secure).
Any other order risks contaminating items.
4. A nurse performs hand hygiene with alcohol-based rub.
When is this inappropriate?
A. Before touching a patient
B. After removing gloves
C. When hands are visibly soiled
D. Before a sterile procedure
Answer: C
Rationale: Alcohol rub does not remove dirt, blood, or
organic matter. Visibly soiled hands require soap and
water for at least 20 seconds. Options A, B, and D are
appropriate times for alcohol rub if hands are not visibly
soiled.
5. The nurse places a client with active pulmonary
tuberculosis in a negative-pressure room. This is an
example of which transmission-based precaution?
3
, A. Droplet
B. Contact
C. Airborne
D. Standard
Answer: C
Rationale: TB requires airborne precautions, including
negative-pressure (airborne infection isolation) rooms.
Droplet (A) does not require negative pressure. Contact
(B) is for skin/enteric pathogens. Standard precautions (D)
apply to all patients but are not sufficient for TB.
6. Which client requires droplet precautions?
A. Client with MRSA wound infection
B. Client with rubella
C. Client with pulmonary tuberculosis
D. Client with scabies
Answer: B
Rationale: Rubella (German measles) spreads via large
