A client has a three-way catheter in place status post transurethral resection of the prostate (TURP) and is experiencing bladder spasms. Which medication should the nurse advocate to be prescribed?
Oxybutynin
Phenazopyridine
Finasteride
Tamsulosin
The Correct Answer is A
A. Oxybutynin: Oxybutynin is an anticholinergic that reduces bladder spasms by relaxing the detrusor muscle. It is commonly prescribed post-TURP to relieve discomfort caused by involuntary bladder contractions, especially when a catheter is in place.
B. Phenazopyridine: Phenazopyridine is a urinary analgesic that helps relieve pain, burning, and urgency associated with urinary tract irritation. However, it does not address the underlying muscle spasms that occur post-TURP.
C. Finasteride: Finasteride is a 5-alpha-reductase inhibitor used for long-term management of BPH by shrinking the prostate. It is not effective for acute relief of post-procedural bladder spasms and works slowly over months.
D. Tamsulosin: Tamsulosin is an alpha-1 blocker that relaxes prostatic and bladder neck muscles to improve urine flow. While useful in BPH management, it does not treat the muscle spasms that can occur after catheterization or TURP.

Correct Answer is A
Explanation
A. Draws water into the bowel movement by changing pressure within the intestines: Magnesium citrate is a saline laxative that works by osmosis, drawing water into the intestines. This increases intraluminal pressure and stimulates bowel motility, leading to a bowel movement within hours.
B. Water and lipids coat the fecal material facilitating a bowel movement: This describes the action of stool softeners or lubricants like docusate sodium or mineral oil, not magnesium citrate. These agents reduce surface tension or coat stool to ease passage.
C. Stimulates the parasympathetic nerves in the intestines to increase peristalsis to cause a bowel movement: Stimulant laxatives like bisacodyl or senna work by directly stimulating intestinal nerves. Magnesium citrate does not act via nerve stimulation.
D. The medication absorbs liquid and swells to trigger a bowel movement: This is the mechanism of bulk-forming laxatives such as psyllium, which absorb water and swell to stimulate intestinal activity. Magnesium citrate functions through osmotic fluid retention.
Correct Answer is A
Explanation
A. Naloxone: Diphenoxylate is an opioid derivative used to treat diarrhea, and naloxone is an opioid antagonist that reverses its central nervous system and respiratory depressant effects in overdose. It is the drug of choice in this situation.
B. Flumazenil: Flumazenil is a benzodiazepine antagonist used to reverse the effects of drugs like diazepam or lorazepam. It has no therapeutic effect on opioid toxicity and would not be useful here.
C. Digibind: Digibind is an antidote used specifically for digoxin toxicity. It binds to circulating digoxin to neutralize its effects, but it has no role in opioid-related overdoses.
D. Glucagon: Glucagon is used in cases of beta-blocker overdose or severe hypoglycemia. It is not effective against diphenoxylate toxicity and would not be administered in this context.
