Final answer:
Osmotic laxatives are the class of laxatives that is least likely to cause dehydration.
Step-by-step explanation:
The class of laxatives that is least likely to cause dehydration is the osmotic laxatives. Osmotic laxatives work by drawing water into the intestines to soften the stool and promote bowel movements. Examples of osmotic laxatives include polyethylene glycol (PEG), lactulose, and sorbitol.
Unlike stimulant laxatives, osmotic laxatives do not stimulate the intestines to increase bowel movements. Instead, they rely on the presence of water to help move the stool through the digestive system. While osmotic laxatives can cause mild dehydration if not taken with enough water, their mechanism of action is less likely to lead to severe dehydration compared to other classes of laxatives.
In summary, osmotic laxatives are the class of laxatives that is least likely to cause dehydration.
