Answer to Question 1

ANS: C
Stool softeners such as docusate are used to prevent constipation in patients who should avoid straining at stool. These patients include those with myocardial infarction or those who have had rectal surgery.

Answer to Question 2

ANS: B
Docusate potassium is a stool softener. Drugs in this group incorporate water and lipids into the stool, producing an emollient action that reduces surface tension. The added water makes the fe-cal mass softer as well.
