Question 1
Which of the following patients is at the highest risk of developing pressure injuries?
A. A young adult with mild fever and normal mobility
B. A patient who is obese and immobile following surgery
C. A patient with controlled hypertension and good appetite
D. A patient who walks independently with no comorbidities
Correct Answer: B. A patient who is obese and immobile following surgery
Rationale: Pressure injuries develop due to prolonged pressure over bony
prominences, especially in patients with reduced mobility. Obesity and immobility
significantly increase risk due to pressure distribution issues and reduced
repositioning ability. While underweight patients, malnutrition, incontinence, and
advanced age also increase risk, immobility remains the strongest contributing factor
in this scenario. The other options describe patients with minimal or no risk factors.
Question 2
Which oxygen saturation level indicates abnormal oxygenation?
A. 97%
B. 95%
C. 92%
D. 88%
Correct Answer: D. 88%
Rationale: Normal oxygen saturation is typically 95–100%. A value below 90%
indicates significant hypoxemia requiring intervention. 88% reflects impaired
oxygenation and may require supplemental oxygen or urgent assessment. The other
values fall within acceptable or borderline ranges.

Question 3
A patient is experiencing difficulty breathing. What is the priority nursing
intervention?
A. Encourage deep coughing
B. Administer oral fluids
C. Sit the patient upright
D. Take a full health history
Correct Answer: C. Sit the patient upright
Rationale: Positioning is the priority intervention in respiratory distress. High
Fowler’s or semi-Fowler’s improves lung expansion and oxygenation. Other
interventions may be important later but do not provide immediate improvement in
breathing.
Question 4
Which finding indicates decreased tissue perfusion?
A. Warm skin and brisk capillary refill
B. Strong peripheral pulses
C. Cyanosis and cold extremities
D. Rapid wound healing
Correct Answer: C. Cyanosis and cold extremities
Rationale: Poor tissue perfusion leads to reduced oxygen delivery, resulting in
cyanosis, cold skin, decreased pulses, and delayed capillary refill. Warm skin and
strong pulses indicate adequate perfusion.
Question 5
Which intervention is appropriate for a visually impaired patient?
A. Keep the room dimly lit
B. Remove all assistive devices
C. Keep objects within reach and orient the patient
D. Encourage independence without support
Correct Answer: C. Keep objects within reach and orient the patient
Rationale: Safety and orientation are essential for visually impaired patients. Keeping
items accessible and orienting the patient reduces risk of injury. Removing support or
encouraging unsafe independence increases fall risk.

Question 6
Which are modifiable risk factors for cardiovascular disease?
A. Age and genetics
B. Gender and age
C. Smoking and diet
D. Family history
Correct Answer: C. Smoking and diet
Rationale: Modifiable risk factors are lifestyle-related, including smoking, diet,
exercise, weight, and stress. Age, gender, and genetics are non-modifiable.
Question 7
Which is a non-modifiable risk factor for cardiovascular disease?
A. Smoking
B. Obesity
C. Genetics
D. Physical inactivity
Correct Answer: C. Genetics
Rationale: Genetics cannot be changed. Smoking, obesity, and inactivity are
modifiable through lifestyle changes.
Question 8
Which intervention promotes heart health?
A. Smoking cessation
B. Increased alcohol intake
C. High caffeine consumption
D. Sedentary lifestyle
Correct Answer: A. Smoking cessation
Rationale: Smoking cessation reduces cardiovascular risk significantly. Alcohol,
caffeine excess, and inactivity increase risk.
Question 9
Which nursing intervention improves gustatory (taste) impairment?
