A client with an ileostomy presents with dehydration. Which contraindicated medication may have contributed to their condition?

The medication that may have contributed to the dehydration of a client with an ileostomy is bisacodyl. This medication is a stimulant laxative that works by increasing the movement in the intestines, thereby promoting bowel movements. In individuals with an ileostomy, the normal absorption mechanisms of the intestines are altered, leading to a higher risk of fluid and electrolyte imbalances.

Stimulant laxatives can further exacerbate this issue by increasing gastrointestinal motility, which may lead to increased fluid loss and make it difficult for the body to retain electrolytes and water. Patients with an ileostomy often have a higher output of stool, so the combination of a stimulant laxative with this condition may significantly increase the risk of dehydration.

In contrast, folate, ferrous sulfate, and cyanocobalamin are not typically contraindicated for individuals with an ileostomy. These medications are commonly prescribed for various deficiencies and should not have the same dehydrating effects as a stimulant laxative like bisacodyl.
