1. Which artery is most commonly used to measure pulse during routine
vital signs?
A. Carotid
B. Radial
C. Brachial
D. Femoral
Answer: B. Radial
Rationale: The radial artery at the wrist is most accessible, safe, and reliable
for measuring pulse in adults during routine exams.


2. A patient’s blood pressure is 150/95 mmHg. How should this be
classified?
A. Normal
B. Elevated
C. Hypertension Stage 1
D. Hypertension Stage 2
Answer: C. Hypertension Stage 1
Rationale: According to AHA guidelines, Stage 1 hypertension = SBP 140–
159 or DBP 90–99.


3. What is the correct angle for an intramuscular injection?
A. 15°
B. 45°
C. 90°
D. 120°

,Answer: C. 90°
Rationale: IM injections are given deep into the muscle at a 90° angle for
proper absorption.


4. Which vitamin is essential for blood clotting?
A. Vitamin A
B. Vitamin K
C. Vitamin D
D. Vitamin E
Answer: B. Vitamin K
Rationale: Vitamin K is required for synthesis of clotting factors II, VII, IX,
and X.


5. Which of the following is a universal precaution?
A. Taking a patient’s weight
B. Washing hands before and after patient contact
C. Checking insurance information
D. Recording vital signs
Answer: B. Washing hands before and after patient contact
Rationale: Universal precautions include hand hygiene, PPE, and proper
sharps disposal to prevent infection spread.


6. What is the first step in the chain of infection?
A. Susceptible host
B. Infectious agent
C. Mode of transmission
D. Reservoir
Answer: B. Infectious agent
Rationale: The chain begins with the microorganism itself, such as bacteria,
virus, or fungus.

,7. What is the most accurate method for measuring a patient’s
temperature?
A. Axillary
B. Oral
C. Rectal
D. Temporal
Answer: C. Rectal
Rationale: Rectal temperature is closest to core body temperature and
therefore most accurate.


8. Which of the following is a parenteral route of medication
administration?
A. Oral
B. Sublingual
C. Intramuscular
D. Rectal
Answer: C. Intramuscular
Rationale: Parenteral means bypassing the digestive system, including IM,
IV, SubQ, and intradermal injections.


9. Which electrode serves as the ground in a standard 12-lead EKG?
A. Right leg
B. Left arm
C. Right arm
D. Left leg
Answer: A. Right leg
Rationale: The right leg electrode stabilizes readings and serves as the
ground.

, 10. Which is the normal range for an adult respiratory rate?
A. 8–12 breaths per minute
B. 12–20 breaths per minute
C. 20–28 breaths per minute
D. 28–32 breaths per minute
Answer: B. 12–20 breaths per minute
Rationale: The average normal adult respiratory rate is between 12 and 20.


11. Which of the following is the correct order of the blood flow through
the heart?
A. Right atrium → right ventricle → lungs → left atrium → left ventricle
B. Left atrium → left ventricle → lungs → right atrium → right ventricle
C. Right ventricle → right atrium → lungs → left atrium → left ventricle
D. Left ventricle → left atrium → lungs → right atrium → right ventricle
Answer: A. Right atrium → right ventricle → lungs → left atrium → left
ventricle
Rationale: This is the correct sequence of circulation: deoxygenated blood
enters right side, goes to lungs, then oxygenated blood returns to left side
of the heart.


12. Which needle gauge is most commonly used for intramuscular
injections?
A. 18–20 gauge
B. 21–23 gauge
C. 25–27 gauge
D. 30 gauge
Answer: B. 21–23 gauge
Rationale: IM injections require a thicker needle (21–23 gauge) to deliver
