  19. What are carbon dioxide releasing laxs? what are hyperosmotic laxs?
    • CO2: potassium and sodium bicarb
    • suppositories that encourage bowel movements by forming C)2, a gas. This gas pushes against intestinal wall, causing contractions that move along the stool mass
    • hyperos lax: glycerin;sodium phosphates
    • draw water into the bowel from surrounding body tissues. this provides a soft stool mass and increased bowel reaction.
  20. What are mineral oil laxs? stimulant laxs?
