A. 0.1 mg
B. 0.5 mg
C. 1 mg
D. 3 mg

Answer 1

The initial dose of atropine for a symptomatic patient with sinus bradycardia and a HR of 42/min along with diaphoresis and low BP is 0.5 mg.

Step-by-step explanation:

For a patient with sinus bradycardia and a heart rate (HR) of 42 beats per minute, who also exhibits symptoms such as diaphoresis (excessive sweating) and hypotension (a blood pressure of 80/60 mmHg), the initial dose of atropine would be 0.5 mg. This is in accordance with the Advanced Cardiovascular Life Support (ACLS) guidelines for the treatment of symptomatic bradycardia. If there is no response to the initial dose, additional doses may be given, up to a total maximum dose of 3 mg.
