Question 1 of 5
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?
Correct Answer: B
Rationale: The correct answer is B: Magnesium hydroxide. This is because magnesium hydroxide, commonly found in antacids and laxatives, can cause false-positive results in a fecal occult blood test (FOBT) due to its chemical reaction with the test reagents. Instructing the client to avoid magnesium hydroxide for at least 3 days before the test ensures accurate results.
Incorrect choices:
A: Whole grain cereal - Whole grain cereal does not interfere with FOBT results.
C: Orange juice - Orange juice does not impact FOBT results.
D: Acetaminophen - Acetaminophen does not affect FOBT results.
Therefore, avoiding magnesium hydroxide is crucial to obtaining reliable results in the FOBT.
