1. A 65-year-old male presents with crushing chest pain and
diaphoresis. What is the most appropriate first medication to
administer if no contraindications exist?
A. Nitroglycerin
B. Aspirin
C. Morphine
D. Heparin
Answer: B. Aspirin
Rationale: Aspirin is given early in suspected acute coronary
syndrome because it inhibits platelet aggregation and reduces
mortality.
2. Which cardiac rhythm is most likely to benefit from immediate
defibrillation?
, A. Asystole
B. Pulseless electrical activity
C. Ventricular fibrillation
D. Sinus bradycardia
Answer: C. Ventricular fibrillation
Rationale: Ventricular fibrillation is a shockable rhythm requiring
immediate defibrillation to restore organized cardiac activity.
3. What is the correct compression-to-ventilation ratio for an adult
patient during CPR with an advanced airway in place?
A. 15:2
B. 30:2
C. Continuous compressions with 10 breaths/min
D. 5:1
Answer: C. Continuous compressions with 10 breaths/min
Rationale: Once an advanced airway is placed, compressions are
continuous and ventilations are delivered at 10 breaths per
minute.
4. Which medication is indicated for symptomatic bradycardia?
A. Epinephrine
, B. Atropine
C. Lidocaine
D. Dopamine
Answer: B. Atropine
Rationale: Atropine is the first-line drug for symptomatic
bradycardia as it increases heart rate by blocking vagal tone.
5. A patient with severe asthma is unresponsive to inhaled
bronchodilators. What is the next appropriate intervention?
A. Oral steroids
B. IV magnesium sulfate
C. Antibiotics
D. Diuretics
Answer: B. IV magnesium sulfate
Rationale: Magnesium sulfate is used in severe asthma
exacerbations as a bronchodilator when first-line treatments fail.
6. What is the primary action of epinephrine during cardiac arrest?
A. Decreases heart rate
B. Vasodilation
C. Increases coronary perfusion pressure
, D. Reduces oxygen demand
Answer: C. Increases coronary perfusion pressure
Rationale: Epinephrine causes vasoconstriction, improving blood
flow to vital organs during CPR.
7. Which condition is characterized by a widened QRS complex and
peaked T waves?
A. Hypokalemia
B. Hyperkalemia
C. Hyponatremia
D. Hypocalcemia
Answer: B. Hyperkalemia
Rationale: Elevated potassium levels cause characteristic ECG
changes including peaked T waves and widened QRS complexes.
8. What is the preferred route for medication administration during
cardiac arrest if IV access is unavailable?
A. Oral
B. Subcutaneous
C. Intraosseous
D. Intramuscular
