1. A 28-year-old male is found unresponsive on the floor with shallow
breathing and a slow pulse. As an EMT, what is the MOST appropriate
first action upon initial patient contact?
A. Immediately begin chest compressions
B. Apply oxygen via non-rebreather mask
C. Ensure scene safety and assess for hazards
D. Obtain a full SAMPLE history
Correct Answer: C
Rationale: The first priority in any EMS response is scene safety to protect
both the provider and the patient. Care cannot begin until environmental
hazards are identified and controlled.
2. A patient is experiencing severe respiratory distress with audible
wheezing and is using accessory muscles. Which condition is MOST
consistent with these findings?
A. Pneumothorax
B. Asthma exacerbation
, C. Stroke
D. Hypoglycemia
Correct Answer: B
Rationale: Wheezing, accessory muscle use, and respiratory distress are
classic signs of bronchoconstriction commonly seen in asthma
exacerbations.
3. Which oxygen delivery device provides the HIGHEST concentration of
oxygen in a spontaneously breathing patient?
A. Nasal cannula
B. Simple face mask
C. Non-rebreather mask
D. Venturi mask
Correct Answer: C
Rationale: A non-rebreather mask can deliver up to near 90–95% oxygen
when properly applied with a high flow rate and reservoir bag inflated.
4. A diabetic patient is confused, sweaty, and tachycardic. What is the
MOST likely cause?
A. Hyperglycemia
B. Hypoglycemia
C. Stroke
D. Seizure disorder
Correct Answer: B
Rationale: Diaphoresis, confusion, and tachycardia are hallmark signs of
hypoglycemia due to sympathetic nervous system activation.
5. What is the correct depth of chest compressions for an adult in cardiac
arrest?
A. At least 1 inch
B. About 1.5 inches
, C. At least 2 inches
D. More than 3 inches
Correct Answer: C
Rationale: Adult CPR guidelines recommend compressions at least 2 inches
deep to generate adequate cardiac output during resuscitation.
6. A patient has a flail chest injury. What is the PRIMARY concern?
A. Internal bleeding from liver
B. Paradoxical chest movement causing impaired ventilation
C. Fractured clavicle
D. Spinal cord injury
Correct Answer: B
Rationale: Flail chest results in paradoxical movement of a chest segment,
severely compromising ventilation and oxygenation.
7. Which artery is typically used to check a pulse in an unconscious adult
patient?
A. Radial artery
B. Brachial artery
C. Carotid artery
D. Femoral artery
Correct Answer: C
Rationale: The carotid artery is used in unconscious adults because it is
central and reliable even during low perfusion states.
8. What is the FIRST medication commonly administered for anaphylaxis
in EMS care?
A. Albuterol
B. Epinephrine
C. Diphenhydramine
D. Aspirin
