SECTION 1: PATIENT CARE & ASSESSMENT
1. What is the primary responsibility of a Hospital Corpsman in a clinical setting?
A. Performing independent surgery
B. Providing patient care and supporting medical operations
C. Prescribing medications without authorization
D. Managing hospital finances
Correct Answer: B. Providing patient care and supporting medical operations
Rationale: Hospital Corpsmen provide direct patient care, assist healthcare providers, maintain
readiness, and support medical missions. Independent surgery and prescribing medications are outside
the scope of practice for a Corpsman .
2. Which vital sign provides information about the force of blood against arterial walls?
A. Temperature
B. Pulse
C. Blood pressure
D. Respiratory rate
Correct Answer: C. Blood pressure
Rationale: Blood pressure measures the pressure exerted by circulating blood on arterial walls. Normal
adult blood pressure is approximately 120/80 mmHg .
3. What is the normal resting adult respiratory rate?
A. 2–6 breaths/min
B. 12–20 breaths/min
C. 25–35 breaths/min
D. 40–50 breaths/min
Correct Answer: B. 12–20 breaths/min
Rationale: A normal resting adult respiratory rate is generally 12–20 breaths per minute. Rates outside
this range may indicate respiratory distress or other medical conditions .
,4. What is the normal adult temperature range?
A. 90–92°F
B. 97–99°F
C. 104–106°F
D. 110°F
Correct Answer: B. 97–99°F
Rationale: Normal adult temperature is approximately 98.6°F but varies slightly among individuals.
Temperatures above 100.4°F generally indicate fever .
5. The first step in treating a casualty with life-threatening bleeding is to:
A. Obtain a medical history
B. Apply pressure or a tourniquet as indicated
C. Give oral fluids
D. Check allergies
Correct Answer: B. Apply pressure or a tourniquet as indicated
Rationale: Controlling severe bleeding is a priority in emergency care to prevent shock and death. Life-
threatening hemorrhage must be addressed before obtaining history or other interventions .
6. What is the purpose of a tourniquet?
A. Reduce fever
B. Control severe extremity bleeding
C. Measure blood pressure
D. Immobilize fractures
Correct Answer: B. Control severe extremity bleeding
Rationale: Tourniquets are used to control life-threatening bleeding from an arm or leg when direct
pressure is ineffective or impractical .
7. Which position is commonly used for a patient experiencing difficulty breathing?
A. Trendelenburg position
B. Supine position
C. Fowler's position
D. Prone position
Correct Answer: C. Fowler's position
, Rationale: Fowler's position (semi-upright) promotes lung expansion and improves breathing by
allowing the diaphragm to descend more effectively .
8. The Glasgow Coma Scale evaluates a patient's:
A. Pain level only
B. Neurological status
C. Blood pressure
D. Oxygen level
Correct Answer: B. Neurological status
Rationale: The Glasgow Coma Scale assesses a patient's level of consciousness based on eye opening,
verbal response, and motor response, with scores ranging from 3 to 15 .
9. What piece of equipment is used to measure oxygen saturation?
A. Sphygmomanometer
B. Thermometer
C. Pulse oximeter
D. Stethoscope
Correct Answer: C. Pulse oximeter
Rationale: A pulse oximeter measures the percentage of oxygen saturation in the blood non-invasively,
typically on a finger or earlobe. Normal SpO2 is 95–100% .
10. Which piece of equipment is used to listen to heart and lung sounds?
A. Otoscope
B. Stethoscope
C. Ophthalmoscope
D. Sphygmomanometer
Correct Answer: B. Stethoscope
Rationale: The stethoscope is used to auscultate heart, lung, and bowel sounds. The bell is used for low-
frequency sounds, and the diaphragm for high-frequency sounds .
11. Which patient has the highest priority during triage?
A. Patient with a minor cut
B. Patient requesting medication refill
