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: Blurred vision is not an expected side effect of digoxin, but a sign of digoxin toxicity, which requires immediate medical attention.
Choice B reason: This is the correct answer because digoxin can cause hypokalemia (low potassium levels), which increases the risk of digoxin toxicity. Therefore, clients taking digoxin need to have their potassium levels monitored regularly and consume foods rich in potassium.
Choice C reason: Antacids can interfere with the absorption of digoxin and reduce its effectiveness. Clients taking digoxin should avoid taking antacids within two hours of taking the medication.
Choice D reason: Weighing oneself every other day is not related to digoxin therapy, but to fluid balance. Clients with heart failure, who are often prescribed digoxin, need to monitor their weight daily and report any significant changes to their health care provider.
