Answer to Question 1
ANS: D
Phenazopyridine hydrochloride is used to produce a local anesthetic effect on the mucosa of the ureters and bladder. Patients should be instructed that phenazopyridine causes urine to become reddish orange, which is not a cause for alarm. Other secretions may also be reddish orange and contact lenses may become stained. Phenazopyridine does not cause a foul odor in the urine. Diarrhea is not a common adverse effect of phenazopyridine. Icterus is a sign of hepatic damage and should be reported to the health care provider.

Tolterodine is used to reduce the urgency and frequency of bladder contractions and delay the initial desire to void in patients with an OAB. Tolterodine does not restore bladder tone and function, prevent urinary retention, or acidify urine.
