Question 1
A 58-year-old man develops crushing chest pain that radiates to his left arm. He is pale,
diaphoretic, and complains of nausea. Vital signs are BP 146/90 mmHg, HR 98 bpm, RR 22/min,
and SpO₂ 95%.
What is the highest priority prehospital intervention?
A. Encourage the patient to walk to the ambulance
B. Obtain a detailed medical history before treatment
C. Administer oxygen only if indicated, obtain a 12-lead ECG, and prepare for rapid transport
D. Delay transport until pain completely resolves
Correct Answer: C
Solution
The patient's presentation strongly suggests acute coronary syndrome (ACS).
The EMS priorities are:
 Perform primary assessment.
 Obtain a 12-lead ECG as early as possible.
 Administer oxygen only if hypoxic or clinically indicated.
 Consider aspirin if no contraindications.
 Prepare rapid transport to a PCI-capable facility.
Walking increases myocardial oxygen demand and should be avoided.


Question 2
Which airway maneuver is preferred in a trauma patient with a suspected cervical spine injury?
A. Head tilt–chin lift

,B. Jaw thrust
C. Hyperextension of the neck
D. Neck rotation
Correct Answer: B
Solution
The jaw-thrust maneuver opens the airway while minimizing cervical spine movement.
Head tilt–chin lift is appropriate only when spinal injury is not suspected.
Maintaining spinal alignment reduces the risk of secondary spinal cord injury.


Question 3
An unconscious patient has no pulse and is not breathing normally.
What should the EMS provider do first?
A. Obtain a blood glucose level
B. Begin high-quality CPR
C. Insert an IV catheter
D. Transport immediately without treatment
Correct Answer: B
Solution
The patient is in cardiac arrest.
Immediate priorities:
 Begin chest compressions
 Attach AED/defibrillator
 Analyze rhythm
 Defibrillate if indicated
 Continue CPR with minimal interruptions
High-quality CPR is the intervention most associated with improved survival.

,Question 4
A patient with severe asthma has audible wheezing, difficulty speaking, and accessory muscle
use.
Which medication is usually administered first?
A. Nitroglycerin
B. Albuterol
C. Morphine
D. Atropine
Correct Answer: B
Solution
Albuterol is a short-acting beta₂ agonist that relaxes bronchial smooth muscle.
Benefits include:
 Bronchodilation
 Improved airflow
 Reduced wheezing
 Relief of respiratory distress
Nitroglycerin treats cardiac chest pain, not bronchospasm.


Question 5
During patient assessment, capillary refill is delayed, skin is cool, and the radial pulse is weak.
These findings most likely indicate:
A. Adequate perfusion
B. Early shock
C. Hyperthermia
D. Hypertension
Correct Answer: B
Solution

, Signs of early shock include:
 Cool clammy skin
 Delayed capillary refill
 Weak peripheral pulses
 Tachycardia
 Anxiety
Prompt recognition allows early intervention before decompensation occurs.


Question 6
Which patient should receive the highest triage priority during a mass-casualty incident?
A. Minor abrasions
B. Walking wounded with ankle pain
C. Unresponsive patient with airway obstruction that opens after repositioning
D. Stable patient with wrist fracture
Correct Answer: C
Solution
Under START triage:
Patients who begin breathing after airway repositioning receive Immediate (Red) priority
because they have a life-threatening but potentially correctable condition.
Walking wounded are categorized as Minor (Green).


Question 7
A diabetic patient is confused and has a blood glucose level of 42 mg/dL.
The patient is awake and able to swallow.
What is the most appropriate treatment?
A. Oral glucose
B. Insulin
