1. Question: Infection Control
A nurse is caring for a patient with suspected tuberculosis. Which precaution is most
appropriate?
A. Contact precautions
B. Droplet precautions
C. Airborne precautions
D. Standard precautions only
Answer: C. Airborne precautions
Explanation:
Tuberculosis spreads through airborne particles. The nurse must use an N95 respirator and place
the patient in a negative-pressure room. Contact and droplet precautions are insufficient.
2. Question: Hand Hygiene
When should a nurse perform hand hygiene?
A. Before touching a patient
B. After removing gloves
C. After contact with bodily fluids
D. All of the above
Answer: D. All of the above
Explanation:
Hand hygiene is required at all these times to prevent infection transmission. Gloves do not
replace hand hygiene.
3. Question: Vital Signs
Which vital sign change requires immediate attention?
A. Temperature: 37.2°C
B. Pulse: 72 bpm
,C. Respiratory rate: 8 breaths/min
D. Blood pressure: 120/80 mmHg
Answer: C. Respiratory rate: 8 breaths/min
Explanation:
A respiratory rate below 12 is abnormal (bradypnea) and may indicate respiratory depression,
requiring urgent intervention.
4. Question: Patient Safety
What is the best intervention to prevent patient falls?
A. Keep side rails up at all times
B. Ensure call light is within reach
C. Restrain the patient
D. Keep the room dark
Answer: B. Ensure call light is within reach
Explanation:
Providing access to assistance reduces fall risk. Restraints and unnecessary side rails can increase
injury risk.
5. Question: Standard Precautions
Which patient requires standard precautions only?
A. Patient with HIV
B. Patient with MRSA
C. Patient with influenza
D. Patient with tuberculosis
Answer: A. Patient with HIV
Explanation:
HIV is not spread by casual contact, so standard precautions are sufficient. Others require
additional precautions.
6. Question: Body Mechanics
Which action demonstrates proper body mechanics?
,A. Bending at the waist
B. Keeping feet close together
C. Using leg muscles to lift
D. Twisting while lifting
Answer: C. Using leg muscles to lift
Explanation:
Using legs prevents back injury. Avoid bending at the waist or twisting.
7. Question: Oxygenation
Which position improves lung expansion in a patient with breathing difficulty?
A. Supine
B. Trendelenburg
C. Fowler’s position
D. Sims’ position
Answer: C. Fowler’s position
Explanation:
Fowler’s position allows maximum chest expansion and improves oxygenation.
8. Question: Documentation
Which entry is appropriate in nursing documentation?
A. “Patient seems better today”
B. “Patient is lazy and uncooperative”
C. “Patient ambulated 20 meters with assistance”
D. “Patient is fine”
Answer: C. “Patient ambulated 20 meters with assistance”

Documentation must be objective, measurable, and factual—not vague or judgmental.
9. Question: Infection Chain
Which element breaks the chain of infection most effectively?
, A. Increasing patient comfort
B. Hand hygiene
C. Providing nutrition
D. Administering medications
Answer: B. Hand hygiene
Explanation:
Hand hygiene interrupts transmission, the most critical step in infection control.
10. Question: Personal Protective Equipment (PPE)
What is the correct order for removing PPE?
A. Gloves → Goggles → Gown → Mask
B. Mask → Gloves → Gown → Goggles
C. Gown → Gloves → Mask → Goggles
D. Gloves → Gown → Goggles → Mask
Answer: D. Gloves → Gown → Goggles → Mask
Explanation:
Gloves are the most contaminated and removed first. Mask is removed last to protect respiratory
tract.
11. Question: Chain of Infection
Which is the correct order in the chain of infection?
A. Host → Agent → Transmission → Portal of entry
B. Agent → Reservoir → Portal of exit → Transmission → Portal of entry → Host
C. Transmission → Host → Agent → Reservoir
D. Reservoir → Agent → Host → Transmission
Answer: B
Explanation:
The correct sequence is: infectious agent → reservoir → portal of exit → mode of
transmission → portal of entry → susceptible host.
