Answer Choices:
Stimulant laxative
💥 Stimulant laxative — This is correct because stimulant laxatives (like bisacodyl or senna) irritate the intestinal mucosa, causing muscle contractions (peristalsis) to stimulate bowel movement.
💥 Stool softener — This is incorrect because it adds moisture to stool, making it easier to pass, but it doesn’t stimulate peristalsis.
💥 Saline/osmotic laxative — This is incorrect because it draws water into the bowel to soften stool and increase pressure but doesn’t irritate the bowel lining.
💥 Bulk-forming laxative — This is incorrect because it adds fiber and bulk, stretching the bowel and stimulating peristalsis mechanically, not by irritation.
