A nurse is reinforcing discharge teaching about fecal occult blood testing with a client. Which of the following instructions should the nurse include in the teaching?
Correct answer
D
Rationale
Urinating prior to collection prevents urine contamination of the stool sample, ensuring test accuracy. Choice A is incorrect as vitamin C typically doesnÔÇÖt affect this test unless specified. Choice B is unnecessary as pork doesnÔÇÖt universally impact results. Choice C is incorrect; a small sample is sufficient, and excess can skew results.
