Question 1 of 5
Which type of laxative causes peristalsis by irritating the bowel?
Correct Answer: C
Rationale: Stimulant laxatives, like bisacodyl, irritate the bowel lining to stimulate peristalsis, promoting bowel movements. Stool softeners moisten stool, saline/osmotic laxatives draw water into the intestines, and bulk-forming laxatives increase stool bulk without irritation.

Correct Answer: C
Rationale: Rate: 1000 mL / 5 hr = 200 mL/hr. Drops/min: (1000 mL × 15 drops/mL) / 300 min = 50 drops/min.
