The nurse is instructing a client who is newly prescribed psyllium. What information will the nurse include when teaching this client?

. The importance of consuming adequate amounts of fluids: Adequate fluid intake is essential when taking psyllium to prevent the formation of a thick, obstructive gel in the throat or intestines. Insufficient fluids may lead to esophageal or bowel obstruction, especially in older adults. B. The onset of action is 30 to 60 minutes after administration: Psyllium typically takes 12 to 72 hours to produce a bowel movement. It works by absorbing water into the stool to increase bulk, and its action is not immediate. C. The need to monitor for hypoglycemia: Psyllium may mildly lower blood glucose levels, particularly in patients with diabetes. However, routine hypoglycemia monitoring is not usually necessary unless the client is on antidiabetic medications and symptomatic. D. The medication is best taken at bedtime: Psyllium should be taken with meals or right after meals, not at bedtime, to promote regular bowel movements. Taking it before bed may delay its effectiveness and increase the risk of gastrointestinal discomfort or obstruction.
