When caring for a patient who has been admitted for his heart failure, the nurse observes that the patient is experiencing bradycardia. Which drug should be administered to patients who develop bradycardia?
Atropine
Cholestyramine
Inamrinone
Milrinone
The Correct Answer is A
A. Atropine is an anticholinergic medication that increases heart rate by blocking vagal effects on the heart, making it the first-line treatment for symptomatic bradycardia.
B. Cholestyramine is a bile acid sequestrant used to lower cholesterol levels and does not have any effects on heart rate.
C. Inamrinone is a phosphodiesterase inhibitor used in heart failure for inotropic support but is not specifically indicated for bradycardia management.
D. Milrinone is also a phosphodiesterase inhibitor used for heart failure but does not address bradycardia directly.

B. While a dry cough may be relevant for other medications, it is not a primary concern when assessing for the use of pseudoephedrine.
C. Recent use of antibiotics is not directly related to the safety of using pseudoephedrine and is not a typical concern.
D. A history of seizures is not a specific contraindication for using pseudoephedrine, although it may warrant caution in some cases.
