1. Which of the following best describes the primary purpose
of the "Chain of Survival" in emergency cardiac care? A) To
ensure the ambulance arrives within 5 minutes B) To link early access,
early CPR, early defibrillation, and early advanced care to maximize
survival rates Correct Answer: B Rationale: The Chain of Survival
is a sequence of critical actions that, when performed quickly
and effectively, significantly increase the chances of survival
for victims of sudden cardiac arrest.
C) To prioritize hospital admission over field treatment D) To train
laypersons to perform surgery
2. In the context of patient assessment, what does the acronym
"AVPU" stand for when evaluating level of consciousness? A)
Alert, Verbal, Painful, Unresponsive Correct Answer: A Rationale:
AVPU is a rapid method to assess a patient's responsiveness:
Alert (fully awake), Verbal (responds to voice), Painful
(responds only to pain), or Unresponsive (no response).
B) Awake, Vital, Pulse, Urgent C) Active, Vocal, Passive, Unstable D)
Airway, Ventilation, Pressure, Urine
3. What is the correct compression-to-ventilation ratio for
adult CPR performed by a single rescuer? A) 15:2 B) 30:2 Correct
Answer: B Rationale: Current guidelines recommend a 30:2
ratio for adult CPR to maintain adequate blood flow while
providing necessary oxygenation.
C) 5:1 D) 10:2
,4. When using an Automated External Defibrillator (AED),
what is the first step after turning the device on? A) Deliver a
shock immediately B) Attach the electrode pads to the patient’s bare
chest Correct Answer: B Rationale: The AED needs to analyze the
heart rhythm via the pads. They must be placed correctly on
the bare chest before analysis can occur.
C) Check the patient’s pulse for 10 seconds D) Call for additional help
5. Which sign is most indicative of a stroke rather than a
fainting episode? A) Pale skin B) Facial drooping on one side Correct
Answer: B Rationale: Facial asymmetry or drooping is a
classic sign of stroke (part of the FAST assessment: Face,
Arms, Speech, Time), whereas fainting typically presents
with generalized weakness and pallor.
C) Rapid breathing D) Sweating
6. What is the primary danger of administering high-flow
oxygen to a patient with Chronic Obstructive Pulmonary
Disease (COPD)? A) It causes hyperventilation B) It may suppress the
hypoxic drive to breathe in some patients Correct Answer: B
Rationale: Some COPD patients rely on low oxygen levels
(hypoxic drive) rather than high carbon dioxide levels to
stimulate breathing. High oxygen can remove this drive,
causing respiratory arrest.
C) It increases heart rate too rapidly D) It causes immediate lung
collapse
7. In a mass casualty incident (MCI), which triage color tag
indicates a patient who has minor injuries and can walk? A)
Red B) Yellow C) Green Correct Answer: C Rationale: Green tags
are assigned to "walking wounded" or patients with minor
injuries who do not require immediate life-saving
intervention.
D) Black
8. What is the correct depth for chest compressions on an
adult during CPR? A) At least 1 inch (2.5 cm) B) At least 2 inches (5
cm) but no more than 2.4 inches (6 cm) Correct Answer: B Rationale:
Adequate depth is crucial for generating blood flow.
,Compressions should be at least 2 inches deep but not exceed
2.4 inches to avoid internal injury.
C) At least 3 inches (7.5 cm) D) As deep as possible
9. Which airway maneuver is preferred for opening the airway
of a trauma patient with a suspected spinal injury? A) Head-
tilt/chin-lift B) Jaw-thrust maneuver Correct Answer: B Rationale:
The jaw-thrust maneuver opens the airway without
extending the neck, minimizing the risk of exacerbating a
cervical spine injury.
C) Neck extension D) Chin lift only
10. What is the definition of "shock" in a medical emergency
context? A) Emotional distress after an accident B) Inadequate
perfusion of cells and tissues due to poor circulation Correct Answer: B
Rationale: Medical shock is a life-threatening condition
where the circulatory system fails to deliver enough oxygen
and nutrients to the body’s cells.
C) A sudden drop in blood pressure only D) An allergic reaction to
medication
11. When treating a severe external bleed, what is the first
action an EMT should take? A) Apply a tourniquet immediately B)
Apply direct pressure with a sterile dressing Correct Answer: B
Rationale: Direct pressure is the most effective initial method
to control bleeding. Tourniquets are reserved for cases where
direct pressure fails or is impractical (e.g., amputation).
C) Elevate the limb above the heart D) Clean the wound with alcohol
12. Which symptom is characteristic of hypoglycemia (low
blood sugar) in a diabetic patient? A) Dry, hot skin B) Cool,
clammy skin and altered mental status Correct Answer: B Rationale:
Hypoglycemia often presents with sympathetic nervous
system activation (sweating, clamminess) and
neuroglycopenic symptoms (confusion, agitation).
C) Slow, shallow breathing D) Pinpoint pupils
13. What is the proper procedure for removing a helmet from
a motorcycle accident victim? A) Pull it off quickly to check the
airway B) Leave it in place unless it interferes with airway management
or CPR, and remove it with two rescuers if necessary Correct Answer: B
, Rationale: Removing a helmet improperly can cause severe
spinal movement. It should only be removed if absolutely
necessary for airway access or CPR, ideally by two trained
individuals stabilizing the head and neck.
C) Cut the strap and slide it off from the front D) Twist it to loosen the fit
14. Which of the following is a contraindication for using a
nasal cannula for oxygen delivery? A) Patient is conscious B)
Patient has significant facial trauma or nasal obstruction Correct
Answer: B Rationale: Nasal cannulas require clear nasal
passages. Facial trauma or obstruction prevents effective
delivery and may cause further injury.
C) Patient has a history of asthma D) Patient is breathing slowly
15. What is the primary function of epinephrine in
anaphylactic shock? A) To lower blood pressure B) To constrict blood
vessels and relax airway muscles Correct Answer: B Rationale:
Epinephrine counteracts the effects of histamine by
vasoconstriction (raising blood pressure) and
bronchodilation (opening airways), reversing life-
threatening symptoms.
C) To induce sleep D) To increase insulin production
16. In pediatric resuscitation, how does the compression
technique differ from adults for infants? A) Use two hands B) Use
two fingers or the two-thumb encircling hands technique Correct
Answer: B Rationale: For infants, the chest is smaller. Two
fingers (single rescuer) or two thumbs encircling the chest
(two rescuers) allow for adequate depth and force
distribution.
C) Use the heel of one hand D) Compressions are not required
17. What does the "P" in the SAMPLE history acronym stand
for? A) Pulse B) Past medical history Correct Answer: B Rationale:
SAMPLE stands for Signs/Symptoms, Allergies, Medications,
Past medical history, Last oral intake, and Events leading up
to the incident.
C) Pain level D) Position
18. Which condition is characterized by a buildup of fluid in
the lungs, often resulting from left-sided heart failure? A)
