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?
The client takes ibuprofen for headaches.
The client had a hemorrhoidectomy 1 year ago.
The client has a history of breast cancer.
The client consumed citrus juice 3 days before the test.
The Correct Answer is A
Choice A reason: Taking ibuprofen or other nonsteroidal anti-inflammatory drugs (NSAIDs) can cause a false-positive result on a fecal occult blood screening test, as they can irritate the gastrointestinal mucosa and cause bleeding.
Choice B reason: Having a hemorrhoidectomy 1 year ago is unlikely to cause a false-positive result on a fecal occult blood screening test, as hemorrhoids are usually a source of bright red blood that can be seen with naked eye, not occult blood that requires chemical detection.
Choice C reason: Having a history of breast cancer is not related to a false-positive result on a fecal occult blood screening test, as breast cancer does not affect the gastrointestinal tract or cause bleeding in stool.
Choice D reason: Consuming citrus juice 3 days before the test is not likely to cause a false-positive result on a fecal occult blood screening test, as citrus juice does not contain any substances that can interfere with the chemical reaction of the test. However, consuming red meat, raw vegetables, vitamin C supplements, or iron supplements within 3 days before the test can cause false-negative results, as they can mask or degrade occult blood in stool.

Correct Answer is B
Explanation
Choice A reason: Providing the client with small-handled adaptive utensils is not necessary for a visually impaired client. The client may prefer to use their own utensils or regular ones that they are familiar with.
Choice B reason: Describing the food placement as though the plate were a clock is a helpful technique to orient the client to their meal and avoid spills or accidents. The nurse should also ask the client about their preferences and needs before serving the food.
Choice C reason: Discouraging conversations during the client's mealtime is not appropriate for a visually impaired client. The nurse should encourage social interactions and respect the client's dignity and autonomy.
Choice D reason: Arranging for an assistive personnel to feed the client is not indicated for a visually impaired client. The nurse should promote the client's independence and self-care abilities as much as possible.
