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 consumed citrus juice 3 days before the test.

The client has a history of breast cancer.

The client had a hemorrhoidectomy 1 year ago.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal irritation and bleeding, potentially leading to a false-positive result in a fecal occult blood test.

Choice B rationale

Citrus juice consumption is not known to interfere with fecal occult blood tests. It does not cause gastrointestinal bleeding or irritation.

Choice C rationale

A history of breast cancer does not affect the accuracy of a fecal occult blood test. It is unrelated to gastrointestinal bleeding or irritation.

Choice D rationale

A hemorrhoidectomy performed a year ago is unlikely to cause a false-positive result in a fecal occult blood test. The procedure would not lead to current gastrointestinal bleeding or irritation.

Correct Answer is A

Explanation

Choice A rationale

A changed mental status is a common sign of a urinary tract infection, especially in older adults, due to the effects of the infection on the central nervous system.

Choice B rationale

WBC count 9,000/mm³ is within the normal range of 5,000 to 10,000/mm³ and does not indicate an infection on its own.

Choice C rationale

Diminished reflexes are not typically associated with bladder infections and are not a reliable indicator.

Choice D rationale

A temperature of 37.3°C (99.1°F) is within the normal range and does not necessarily indicate a bladder infection.

A. "I will need to empty the bag every 4 to 6 hours.”. B. "I will use moisturizing soap to clean around the stoma before applying the bag.”. C. "I will cut the wafer opening one-fourth of an inch larger than the stoma.”. D. "I will use a skin sealant before I apply the bag.”. . . .

Correct Answer is C

Explanation

Choice A rationale

Emptying the ileostomy bag every 4 to 6 hours is incorrect as the frequency depends on the individual's output, which can be higher, requiring more frequent emptying.

Choice B rationale

Using moisturizing soap to clean around the stoma is not recommended as it can interfere with the adhesion of the wafer. Mild, non-moisturizing soap should be used instead.

Choice C rationale

Cutting the wafer opening one-fourth of an inch larger than the stoma is correct as it allows for proper fitting and prevents constriction of the stoma, reducing the risk of skin irritation.

Choice D rationale

Using a skin sealant before applying the bag is recommended to protect the skin and improve the adhesion of the ostomy appliance. .
