The urinary analgesic phenazopyridine hydrochloride will commonly turn the urine reddish orange. It may also affect the skin or sclera, in which case the health care provider should be contacted. Phenazopyridine does not discolor feces, sputum, or saliva.
Answer to Question 2
ANS: C
Neostigmine is an anticholinesterase agent that binds to cholinesterase, preventing the destruction of acetylcholine. The acetylcholine accumulates at cholinergic synapses, and its effects become prolonged and exaggerated. This produces a general cholinergic response manifested by miosis; increased tone of intestinal, skeletal, and bladder muscles; bradycardia; stimulation of secretions of the salivary and sweat glands; and constriction of the bronchi and ureters. An OAB is treated with anticholinergic agents. Anticholinergic agents with more selective action on the bladder are darifenacin, oxybutynin, solifenacin, tolterodine, and trospium. UTIs are treated with anti-infectives. Benign prostatic hyperplasia-related urinary problems are treated with anticholinergic medications.
