VATI - PHARMACOLOGY - Pharmacological and Parenteral Therapies Quiz 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. IncorrectAtropine does not have a direct effect on the SA node. - ANSThe correct answer is: To accelerate the heart rate by interfering with vagal impulses. Atropine accelerates the heart rate by interfering with vagal impulses. It is given IVP at doses of 0.5mg to 1.0mg per dose; every 3 to 5 minutes; up to 2.0mg. Doses less than 0.5mg may cause a paradoxical slowing of the heart rate. When Atropine is given to a client with history of an MI it should be used with great caution; increasing the heart rate also increases myocardial oxygen consumption!
