1. A 56-year-old patient presents with crushing chest pain, diaphoresis, and
nausea. What is the most appropriate first medication to administer if not
contraindicated?
A. Morphine
B. Aspirin
C. Nitroglycerin
D. Oxygen
Correct Answer: B. Aspirin
Rationale: Aspirin is the first-line medication in suspected acute coronary
syndrome because it inhibits platelet aggregation by blocking thromboxane A2
formation, reducing clot progression. It improves survival when given early
unless contraindicated such as allergy or active bleeding.
2. What is the primary sign of anaphylactic shock?
A. Bradycardia
B. Hypertension
C. Airway swelling and hypotension
D. Hyperglycemia
Correct Answer: C. Airway swelling and hypotension
Rationale: Anaphylaxis is a severe systemic allergic reaction causing
,vasodilation, capillary leak, airway edema, and bronchoconstriction, leading to
hypotension and airway compromise, which are life-threatening features
requiring immediate epinephrine.
3. Which rhythm is most commonly associated with a pulseless, shockable
cardiac arrest?
A. Asystole
B. Pulseless electrical activity
C. Ventricular fibrillation
D. Sinus bradycardia
Correct Answer: C. Ventricular fibrillation
Rationale: Ventricular fibrillation is a chaotic electrical activity that results in
ineffective cardiac contraction and no cardiac output. It is a shockable rhythm
requiring immediate defibrillation for survival.
4. What is the correct initial treatment for an open pneumothorax?
A. Needle decompression
B. Chest seal application
C. High-flow oxygen only
D. Intubation
Correct Answer: B. Chest seal application
Rationale: An open pneumothorax requires sealing the chest wound to prevent
air entry into the pleural space, converting it into a closed system and
preventing tension physiology.
5. What is the normal adult respiratory rate range?
A. 8–10
B. 12–20
, C. 20–28
D. 30–40
Correct Answer: B. 12–20
Rationale: Normal adult respiratory rate is 12–20 breaths per minute, reflecting
adequate ventilation and oxygen exchange in a resting adult.
6. A patient with suspected stroke should have glucose checked primarily to:
A. Diagnose diabetes
B. Rule out hypoglycemia mimic
C. Determine dehydration
D. Assess kidney function
Correct Answer: B. Rule out hypoglycemia mimic
Rationale: Hypoglycemia can present with stroke-like symptoms such as
weakness or altered mental status, so blood glucose must be checked
immediately to differentiate and treat reversible causes.
7. What is the most appropriate airway adjunct for a semiconscious patient
with intact gag reflex?
A. Endotracheal tube
B. Oropharyngeal airway
C. Nasopharyngeal airway
D. Cricothyrotomy
Correct Answer: C. Nasopharyngeal airway
Rationale: The nasopharyngeal airway is tolerated in patients with an intact gag
reflex, maintaining airway patency without triggering vomiting or
laryngospasm.
8. Which condition presents with “coffee-ground” vomitus?
A. Peptic ulcer bleeding
, B. Appendicitis
C. Diverticulitis
D. Hepatitis
Correct Answer: A. Peptic ulcer bleeding
Rationale: Coffee-ground vomitus indicates partially digested blood in the
stomach, often due to upper gastrointestinal bleeding such as peptic ulcer
disease.
9. The main action of epinephrine in cardiac arrest is:
A. Vasodilation
B. Beta-2 bronchodilation only
C. Alpha-mediated vasoconstriction
D. Diuresis
Correct Answer: C. Alpha-mediated vasoconstriction
Rationale: Epinephrine increases coronary and cerebral perfusion pressure
through alpha-1 vasoconstriction, improving chances of return of spontaneous
circulation.
10.Which is the most common cause of airway obstruction in an unconscious
adult?
A. Tongue
B. Foreign body
C. Tumor
D. Epiglottitis
Correct Answer: A. Tongue
Rationale: Loss of muscle tone in unconscious patients allows the tongue to fall
backward, obstructing the upper airway.
