A patient who has chronic constipation asks the nurse about the use of psyllium (Metamucil). Which information will the nurse include in the response?

Rationale: A. Dietary sources of fiber should not be eliminated; in fact, fiber from food complements the effect of psyllium and supports normal bowel function. B. Fiber-containing laxatives can have adverse effects, such as bloating, gas, or, rarely, intestinal obstruction if not taken with adequate fluid. C. Psyllium does not significantly reduce absorption of fat-soluble vitamins; this concern is more relevant to certain other medications, like cholestyramine. D. Psyllium absorbs water in the intestines, forming a bulky stool. To prevent fecal impaction or bowel obstruction, it is essential to take large amounts of fluid when using this type of laxative.
