Complete question is

A client with a digoxin level of 2.4 ng/ml has a heart rate of 39. The health care provider prescribes atropine sulfate. Which of the following best describes the intended action of atropine for this client?

Select one:

a. To accelerate the heart rate by interfering with vagal impulses.

b. To reduce peristalsis and urinary bladder tone.

c. To dry oral and tracheobronchial secretions.

d. To stimulate the SA node and sympathetic fibers to increase the rate.

Solution -

Atropine improves the performance and output of cardiac system by inhibiting the action of vagal or parasympathetic. The rate of discharge from the sinus node (SN) increases and hence the chances of ventricular ectopy reduces.

This drug must be administered rapidly to prevent reflexes of bradycardia. The common dosage regime is 0.5 mg per 3 minutes in adults or as per the instructions of doctor.

Hence, option A is correct
