Aclient 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?

a. to stimulate the sa node and sympathetic fibers to increase the rate.
b. to accelerate the heart rate by interfering with vagal impulses.
c. to dry oral and tracheobronchial secretions.
d. to reduce peristalsis and urinary bladder tone.

\rb. To accelerate the heart rate by interfering with vagal impulses

Explanation:

Digoxin is a cardiac glycoside which has both the cardiac as well as the electric effects. The most important electrical effect includes early parasympathomimmetic responses(decrease in heart rate) which are followed by late arrhythmogenic actions. Thus the parasympathetic effects of digoxin specifically on atria and AV node results in a decrease in heart rate while atropine in given in this condition because it is a parasympatholytic drug thus it reverses the bradycardia induced by digoxin by interfering with vagal impulses and increases the heart rate .

Hence the option \rb. To accelerate the heart rate by interfering with vagal impulses is true.
