Answer to Question 1

A
About 6 to 12 months of postmarketing experience can yield information about drug efficacy and side effects, so patients should be cautioned to wait for these data. Drug company promotional materials have biased information. Most new drugs are more expensive, and costs alone should not determine drug choice. Extended-release forms are often more expensive.

Answer to Question 2

D
Nocturnal cough and shortness of breath may be a side effect of propranolol, which can cause bronchospasm because it is a nonselective -blocker. The NP should discuss a selective B-blocker with the patient's cardiologist. -Blockers should never be stopped abruptly. Bradycardia and hypotension are signs of toxicity. Increasing activity would not counter these side effects if bronchospasm is the cause.
