1. Which component of the scene size-up helps determine whether
additional resources are needed?
A. Primary assessment
B. Patient history
C. Mechanism of injury (MOI) or nature of illness (NOI)
D. SAMPLE history
Answer: C. Mechanism of injury (MOI) or nature of illness (NOI)
Rationale: Determining the MOI or NOI helps the EMT anticipate
injuries or illnesses, identify potential hazards, and determine whether
additional resources or specialized personnel are required.
, 2. What is the normal respiratory rate for a healthy adult?
A. 8–10 breaths per minute
B. 12–20 breaths per minute
C. 22–30 breaths per minute
D. 30–40 breaths per minute
Answer: B. 12–20 breaths per minute
Rationale: Adults typically breathe 12–20 times per minute while at
rest. Rates outside this range may indicate respiratory distress or
another medical condition.
3. Which airway maneuver is preferred for a trauma patient with a
suspected spinal injury?
A. Head tilt–chin lift
B. Jaw-thrust maneuver
C. Finger sweep
D. Recovery position
Answer: B. Jaw-thrust maneuver
Rationale: The jaw-thrust maneuver opens the airway while minimizing
movement of the cervical spine, making it the preferred technique for
trauma patients with suspected spinal injuries.
, 4. Which pulse should be assessed in an unresponsive adult?
A. Radial
B. Femoral
C. Carotid
D. Brachial
Answer: C. Carotid
Rationale: The carotid artery is the recommended pulse site for
assessing circulation in an unresponsive adult because it is a central
pulse that is usually easiest to palpate.
5. Which type of shock results from severe blood loss?
A. Cardiogenic
B. Septic
C. Neurogenic
D. Hypovolemic
Answer: D. Hypovolemic
Rationale: Hypovolemic shock occurs when significant fluid or blood loss
reduces circulating volume, leading to inadequate tissue perfusion.
, 6. 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 generates the pressure necessary to pump
oxygen-rich blood through the aorta and into the systemic circulation.
7. Which oxygen delivery device provides the highest oxygen
concentration to a breathing patient?
A. Nasal cannula
B. Simple face mask
C. Nonrebreather mask
D. Venturi mask
Answer: C. Nonrebreather mask
Rationale: A properly fitted nonrebreather mask with adequate oxygen
flow can deliver up to approximately 90–95% oxygen.
