Answer to Question 1

A
Although both heparin and warfarin are anticoagulants, they have different mechanisms of action and onsets of action. Because warfarin has such a slow onset, it must be started while the patient is still receiving heparin.

Answer to Question 2

A
Diphenhydramine is an antihistamine with anticholinergic actions that include dry mouth, drowsiness, and urinary retention. An enlarged prostate is common among older men and causes difficulty urinating. This problem can be made much worse when taking a drug that can cause urinary retention.
