Answer to Question 1

D
Feedback:
Cardiac glycosides exert a negative cardiotonic and positive inotropic effect. They do not decrease cardiac output, decrease afterload, or increase the ventricular rate of the heart.

Answer to Question 2

A
Feedback:
Adverse effects associated with topical decongestants include local stinging and burning, which may occur the first few times the drug is used. If the sensation does not resolve, the drug should be discontinued, because it may indicate lesions or erosion of the mucous membranes. Nasal decongestants do not cause asthma or increased risk of infection. These medications do not decrease drainage from the nose as they shrink the nasal mucosa.
