Question 1 of 5

A nurse is reviewing the results of a client's fecal occult blood screening test. Which of the following findings from the client's history should the nurse identify as potentially causing a false-positive result?

Correct Answer: B

Rationale: Fecal occult blood tests detect heme, but false positives arise from non-colonic bleeding. Ibuprofen, an NSAID, irritates the GI mucosa, causing microbleeds that mimic colorectal sources, a known confounder clients are advised to stop it pre-test. Citrus juice may cause false negatives (vitamin C interferes with guaiac reaction), not positives, and 3 days minimizes impact. A hemorrhoidectomy 1 year ago, healed, doesn't bleed unless recurrent, not suggested. Breast cancer doesn't affect GI bleeding unless metastatic, unlikely here. Ibuprofen's GI effect aligns with testing pitfalls (e.g., ACG guidelines), making it the likely false-positive source to identify.
