1. Nursing Process
Which phase of the nursing process involves collecting patient data?
A. Planning
B. Assessment
C. Implementation
D. Evaluation
Answer: B. Assessment
Rationale: Assessment is the systematic collection of subjective and objective data used to
identify the patient's health status and nursing care needs.
2. Vital Signs
Which vital sign should the nurse assess first in a patient complaining of shortness of breath?
A. Blood pressure
B. Respiratory rate
C. Temperature
D. Pain score
Answer: B
Rationale: Airway and breathing take priority. Respiratory rate and effort provide immediate
information about respiratory status.
3. Infection Control
Which action best prevents healthcare-associated infections?
A. Wearing gloves only
,B. Proper hand hygiene
C. Wearing a face shield
D. Administering antibiotics
Answer: B
Rationale: Hand hygiene is the single most effective intervention for preventing the spread of
infection.
4. Standard Precautions
Standard precautions should be used:
A. Only for patients with known infections
B. Only in the ICU
C. For all patients regardless of diagnosis
D. Only when blood exposure is expected
Answer: C
Rationale: Standard precautions assume that all blood and body fluids may contain infectious
organisms.
5. Chain of Infection
Which element of the chain of infection is interrupted by handwashing?
A. Susceptible host
B. Mode of transmission
C. Reservoir
D. Portal of exit
Answer: B
Rationale: Hand hygiene interrupts the transmission of microorganisms from one person to
another.
,6. Oxygen Saturation
A normal oxygen saturation for a healthy adult is generally:
A. 80–85%
B. 88–90%
C. 95–100%
D. 70–75%
Answer: C
Rationale: Most healthy adults maintain oxygen saturation between 95% and 100% on room air.
7. Fever
A patient's oral temperature is 39°C (102.2°F). The nurse should recognize this as:
A. Hypothermia
B. Hyperthermia (fever)
C. Normal temperature
D. Heat exhaustion
Answer: B
Rationale: An oral temperature above 38°C (100.4°F) is considered a fever.
8. Pulse Assessment
A pulse deficit is determined by comparing:
A. Apical and radial pulse rates
B. Respiratory and apical rates
C. Blood pressure and pulse
D. Temperature and pulse
Answer: A
Rationale: A pulse deficit occurs when the apical pulse exceeds the radial pulse.
, 9. Blood Pressure
Which blood pressure reading indicates hypertension in an adult?
A. 108/68 mmHg
B. 116/72 mmHg
C. 148/92 mmHg
D. 110/70 mmHg
Answer: C
Rationale: A blood pressure of 148/92 mmHg falls within the hypertensive range and warrants
further evaluation.
10. Pain Assessment
Pain is best described as:
A. Whatever the healthcare provider observes
B. Whatever the patient says it is
C. Based only on facial expression
D. Determined by diagnostic tests
Answer: B
Rationale: Pain is subjective, and the patient's self-report is the most reliable indicator.
11. Documentation
The nurse documents an observation that the patient's skin is "warm and dry." This is:
A. Subjective data
B. Objective data
C. Nursing diagnosis
D. Planning
