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 has a history of breast cancer.
The client takes ibuprofen for headaches.
The client consumed citrus juice 3 days before the test.
The client had a hemorrhoidectomy 1 year ago.
The client had a hemorrhoidectomy 1 year ago.
The Correct Answer is B
The client takes ibuprofen for headaches. NSAIDs such as ibuprofen can cause gastrointestinal bleeding, which can result in a false positive result on a fecal occult blood test.
Option A is incorrect because breast cancer is not associated with false-positive fecal occult blood results.
Option C is incorrect because citrus juice does not affect the fecal occult blood test.
Option D is incorrect because a hemorrhoidectomy is not associated with false-positive fecal occult blood results.
Reasons why the other options are not answered:
Option A: Breast cancer is not associated with false-positive fecal occult blood results.
Option C: Citrus juice does not affect the fecal occult blood test.
Option D: A hemorrhoidectomy is not associated with false-positive fecal occult blood results.

Correct Answer is C
Explanation
The correct answer is choice C: Blood pressure change from 118/78 mm Hg to 86/50 mm Hg.
Choice C rationale: A significant drop in blood pressure can indicate various serious conditions, such as shock, hemorrhage, or a severe infection. The nurse should assess the client further and intervene as necessary to prevent complications.
Choice A rationale: The change in temperature may indicate the onset of a fever and requires further assessment, but it is not as immediately concerning as the sudden drop in blood pressure.
Choice B rationale: The change in respiratory rate could be a result of factors like pain, anxiety, or exercise. While it warrants further assessment, it is not as critical as the blood pressure change.
Choice D rationale: The heart rate change may be a response to medications, rest, or other factors. It should be monitored and assessed, but the priority finding is the blood pressure change, which may indicate a more severe underlying issue.
Correct Answer is C
Explanation
Choice A rationale: Breast self-examinations should be performed monthly, not every other month. This regularity helps with early detection of any changes.
Choice B rationale: Dimpling of the skin on the breasts is not common and can be a sign of breast cancer or other conditions. This statement indicates a misunderstanding.
Choice C rationale: It is indeed common for one breast to be slightly larger than the other. This is a normal variation and not usually a cause for concern.
Choice D rationale: Breast self-examinations should be performed several days after the menstrual period ends, not the day the period begins. This timing helps to reduce the likelihood of hormonal changes affecting breast tissue.
