EMS CERTIFICATION EXAM QUESTIONS WITH
ACCURATE ANSWERS – NEW UPDATE
In a cardiac arrest, the correct chest compression depth for an adult is: A. 1
inch B. 1.5 inches C. 2-2.4 inches D. 3 inches
✅ Answer: C. 2-2.4 inches Explanation: Current guidelines recommend
compressing the chest at least 2 inches but not more than 2.4 inches for
optimal circulation during CPR.
Which of the following is a sign of respiratory distress? A. Pink, warm skin
B. Regular breathing pattern C. Use of accessory muscles D. Decreased
respiratory rate
✅ Answer: C. Use of accessory muscles Explanation: Accessory muscle
use (neck, intercostal muscles) indicates the patient is working harder to
breathe.
The primary purpose of oxygen therapy is to: A. Reduce anxiety B. Prevent
seizures C. Correct hypoxemia D. Decrease blood pressure
✅ Answer: C. Correct hypoxemia Explanation: Oxygen therapy aims to
increase oxygen saturation levels in patients with low blood oxygen.
What is the correct ratio of compressions to breaths in adult CPR with two
rescuers? A. 15:2 B. 30:2 C. 5:1 D. 10:2
✅ Answer: B. 30:2 Explanation: The current AHA guidelines recommend a
30:2 ratio for both one and two-rescuer CPR in adults.
What is the appropriate site for intramuscular injection in an adult? A.
Deltoid B. Gluteus maximus C. Vastus lateralis D. All of the above
, ✅ Answer: D. All of the above Explanation: The deltoid, gluteus maximus,
and vastus lateralis are all appropriate IM injection sites in adults.
What is the appropriate dose of aspirin for a patient with suspected
myocardial infarction? A. 81 mg B. 160-325 mg C. 500 mg D. 650 mg
✅ Answer: B. 160-325 mg Explanation: AHA guidelines recommend 160-
325 mg of chewable aspirin for suspected MI to inhibit platelet aggregation.
Which of the following is a contraindication for using an AED? A. Patient is
wearing a medication patch B. Patient has a pacemaker C. Patient is on a
metal surface D. Patient is in water
✅ Answer: D. Patient is in water Explanation: Water conducts electricity
and can create a shock hazard; the patient should be moved to a dry area.
Normal capillary refill time is: A. Less than 1 second B. Less than 2 seconds
C. Less than 5 seconds D. Less than 10 seconds
✅ Answer: B. Less than 2 seconds Explanation: Normal capillary refill is
less than 2 seconds; longer times may indicate poor perfusion.
What is the primary emergency treatment for anaphylaxis? A.
Diphenhydramine (Benadryl) B. Epinephrine C. Albuterol D. Oxygen
✅ Answer: B. Epinephrine Explanation: Epinephrine is the first-line
treatment for anaphylaxis to counter respiratory and cardiovascular
symptoms.
Which of the following is a sign of compartment syndrome? A. Pain
disproportionate to injury B. Decreased pain with movement C. Warm
extremity D. Strong pulses
✅ Answer: A. Pain disproportionate to injury Explanation: Severe pain
beyond what would be expected for the visible injury is an early warning
sign of compartment syndrome.
The appropriate flow rate for a non-rebreather mask is: A. 3-5 L/min B. 6-10
L/min C. 10-15 L/min D. 1-2 L/min
