A patient who has chronic constipation asks the nurse about the use of psyllium (Metamucil). Which information will the nurse include in the response?
Dietary sources of fiber should be eliminated to prevent excessive gas formation.
Use of this type of laxative to prevent constipation does not cause adverse effects.
Fiber-containing laxatives may reduce the absorption of fat-soluble vitamins.
Large amounts of fluid should be taken to prevent impaction or bowel obstruction.
The Correct Answer is D
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.
