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: Staying nearby can provide comfort and support is not an appropriate response, as it does not acknowledge or validate the partner's feelings of grief and loss. The nurse should listen empathetically and encourage the partner to express their emotions.
Choice B reason: I can understand your feelings of sadness is an appropriate response, as it shows empathy and compassion for the partner's situation and allows them to feel heard and understood.
Choice C reason: I will be positive and optimistic for you is not an appropriate response, as it implies that the partner's feelings are negative or inappropriate and that they need to be changed or fixed. The nurse should respect and accept the partner's feelings without judging or minimizing them.
Choice D reason: You should try to be strong for him is not an appropriate response, as it places pressure and expectations on the partner and discourages them from showing their true feelings. The nurse should support and empower the partner without imposing their own values or beliefs.
