Safety, Infection Control, & PPE
1. A nurse is caring for a client diagnosed with Clostridium difficile. Which type of
isolation precautions should the nurse implement?
A. Droplet precautions
B. Contact precautions
C. Airborne precautions
D. Protective environment
<details><summary><b>Answer & Rationale</b></summary><b>Answer: B.
Contact precautions</b><br><b>Rationale:</b> <i>C. difficile</i> is transmitted
via spores that contaminate surfaces and are easily transferred on hands or
gloves. Contact precautions require a private room and the use of gloves and
gowns when entering the room. Hand washing with soap and water is preferred
over alcohol-based hand rubs because alcohol does not kill the spores
[citation:8].</details>
2. A nurse is preparing to don personal protective equipment (PPE) before
entering a client's room for a sterile procedure. In which order should the nurse
don the PPE?
A. Goggles, mask, gown, gloves
,B. Mask, goggles, gown, gloves
C. Gown, mask, goggles, gloves
D. Gloves, gown, mask, goggles
<details><summary><b>Answer & Rationale</b></summary><b>Answer: C.
Gown, mask, goggles, gloves</b><br><b>Rationale:</b> The correct sequence for
donning PPE is: Gown, then Mask, then Goggles/Face Shield, then Gloves. The
gown is applied first to cover the torso, followed by the mask/respirator to
protect the mucous membranes. Goggles go over the mask, and gloves are
applied last, covering the cuffs of the gown [citation:10].</details>
3. A nurse is assessing a client who presents with a fever, night sweats, and a
cough that has persisted for three weeks. The nurse suspects tuberculosis. Which
type of mask should the nurse wear when entering the room?
A. Surgical mask
B. N95 respirator
C. Simple face mask
D. Non-rebreather mask
<details><summary><b>Answer & Rationale</b></summary><b>Answer: B. N95
respirator</b><br><b>Rationale:</b> Tuberculosis is transmitted via airborne
droplet nuclei. Airborne precautions require an N95 or higher-level respirator to
,filter out very small particles. A surgical mask protects against droplets only and
does not provide an adequate seal for airborne pathogens [citation:8].</details>
4. A nurse receives a report that a client has a stage 3 pressure injury with a foul-
smelling, purulent discharge. Before wound irrigation, what is the priority action?
A. Administer PRN pain medication
B. Assess the client's temperature
C. Gather sterile irrigation supplies
D. Review the wound culture results
<details><summary><b>Answer & Rationale</b></summary><b>Answer: A.
Administer PRN pain medication</b><br><b>Rationale:</b> Wound irrigation and
debridement are painful procedures. The priority action is managing pain before
beginning a painful intervention to promote client comfort and cooperation.
While the other options are important, pain relief addresses the physiological
need immediately before the procedure [citation:8].</details>
5. A nurse is providing discharge teaching to a client going home on contact
precautions for an infected wound. Which statement indicates the client
understands the teaching?
A. "I will wash my hands only after touching my wound."
B. "I can share towels with my family if they are clean."
C. "My family should wear gloves if they help change my bandage."
, D. "I do not need to worry about spreading the infection once I leave the
hospital."
<details><summary><b>Answer & Rationale</b></summary><b>Answer: C. "My
family should wear gloves if they help change my
bandage."</b><br><b>Rationale:</b> Contact precautions continue at home.
Family members should use gloves to avoid direct contact with infected material.
Towels and linens should not be shared. Hand hygiene is required before AND
after contact [citation:10].</details>
6. A client is admitted with bacterial meningitis. Which precautions should the
nurse initiate?
A. Standard precautions only
B. Contact precautions
C. Droplet precautions
D. Airborne precautions
<details><summary><b>Answer & Rationale</b></summary><b>Answer: C.
Droplet precautions</b><br><b>Rationale:</b> Bacterial meningitis is
transmitted via large droplets generated by coughing or suctioning. Droplet
precautions require a private room and a mask if within three feet of the client.
Airborne precautions are required for viral meningitis or specific etiologies like TB
[citation:10].</details>
