1. The normal resting heart rate for an adult is:
A) 40-60 bpm
B) 60-100 bpm
C) 100-120 bpm
D) 120-140 bpm
Answer B: 60-100 bpm
Rationale: Normal adult resting heart rate ranges from 60 to 100 beats per minute.
2. Which chamber of the heart pumps oxygenated blood to the body?
A) Right atrium
B) Right ventricle
C) Left atrium
D) Left ventricle
Answer D: Left ventricle
Rationale: The left ventricle pumps oxygenated blood through the aorta to systemic circulation.
3. The primary function of red blood cells is:
A) Fight infection
B) Transport oxygen
C) Clot blood
D) Produce antibodies
Answer B: Transport oxygen
Rationale: Red blood cells contain hemoglobin, which carries oxygen from the lungs to tissues.
,4. Which of the following is a symptom of hypovolemic shock?
A) Hypertension
B) Tachycardia and hypotension
C) Bradycardia
D) Warm, flushed skin
Answer B: Tachycardia and hypotension
Rationale: Hypovolemic shock causes tachycardia and hypotension due to decreased circulating volume.
5. The largest organ of the human body is the:
A) Liver
B) Skin
C) Heart
D) Lung
Answer B: Skin
Rationale: The skin is the largest organ, covering the entire body surface.
6. A nurse is preparing to administer a medication. Which of the following is the "right" that
ensures the correct client receives the medication?
A) Right dose
B) Right route
C) Right patient
D) Right time
Answer C: Right patient
Rationale: The right patient is verified using two identifiers to prevent medication errors.
7. The normal pH of human blood is approximately:
,A) 7.0
B) 7.35-7.45
C) 7.8
D) 8.0
Answer B: 7.35-7.45
Rationale: Arterial blood pH is tightly regulated between 7.35 and 7.45.
8. In a patient with chronic obstructive pulmonary disease (COPD), the most appropriate oxygen
delivery device is:
A) Non-rebreather mask
B) Nasal cannula at 1-2 L/min
C) Simple face mask
D) Venturi mask at 100%
Answer B: Nasal cannula at 1-2 L/min
Rationale: Low-flow oxygen reduces the risk of CO₂ retention in COPD patients.
9. The medical term for high blood pressure is:
A) Hypotension
B) Hypertension
C) Normotension
D) Orthostatic hypotension
Answer B: Hypertension
Rationale: Hypertension is defined as persistently elevated blood pressure (≥130/80 mmHg).
10. Which of the following is a sign of infection?
A) Bradycardia
B) Fever and elevated white blood cell count
C) Hypotension
, D) Hypothermia
Answer B: Fever and elevated white blood cell count
Rationale: Fever and leukocytosis are classic signs of infection.
11. The nurse is caring for a patient with a nasogastric tube. The nurse should verify tube
placement by:
A) Auscultating air insufflation
B) Checking the pH of aspirated gastric contents
C) Placing the tube in water
D) Observing for bubbling
Answer B: Checking the pH of aspirated gastric contents
Rationale: pH testing (≤5) is reliable; auscultation is not recommended.
12. The primary source of energy for the brain is:
A) Protein
B) Glucose
C) Fat
D) Ketones
Answer B: Glucose
Rationale: The brain relies almost exclusively on glucose for energy.
13. Which vitamin is produced by the skin when exposed to sunlight?
A) Vitamin A
B) Vitamin B12
C) Vitamin D
D) Vitamin E
Answer C: Vitamin D
Rationale: UV light converts 7-dehydrocholesterol in the skin to vitamin D₃.
