Answer to Question 1

B
Feedback:
After IV administration, diuretic effects occur within 5 minutes. The diuretic effect is not seen in 1 minute. The peak of the action occurs in 30 minutes, not the onset of action. The duration of action is 2 hours, not the onset of action.

Answer to Question 2

A
Feedback:
Hypotension is the most significant adverse effect of tizanidine. Dark black urine, excessive salivation, and eczema are not adverse effects of tizanidine.
