Correct answer: B. Atropine
- A. Epinephrine
- B. Atropine
- C. A diuretic
- D. A potent vasadilatior
Explanation
Atropine is the usual first-line drug for symptomatic bradycardia because it blocks vagal muscarinic effects on the sinoatrial and atrioventricular nodes. Epinephrine may be used when atropine fails or in severe unstable cases, but it is not the most common initial treatment.
