A nurse is reinforcing teaching with a client who is to collect stool at home for a fecal occult blood test (FOBT). Which of the following should the nurse instruct the client to avoid for at least 3 days before the test?

Magnesium hydroxide

Orange juice

Whole grain cereal

Acetaminophen

Answer and Explanation

The Correct Answer is B

A. Magnesium hydroxide: Although it is a laxative, it doesn't directly interfere with the chemical detection of blood in the stool.

B. Orange juice: Orange juice is high in vitamin C (ascorbic acid), and vitamin C in sufficient amounts can cause false-negative results on guaiac-based fecal occult blood tests (FOBT). Patients are usually told to avoid vitamin C (citrus fruits/juices and supplements) for about 3 days before and during the collection period.

C. Whole grain cereal: Whole grains are not listed among the foods that typically must be avoided.

D. Acetaminophen: Unlike NSAIDs, acetaminophen does not increase the risk of GI bleeding, so it's generally safe.
