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

Consuming small, frequent meals helps in managing energy levels and reducing the work of breathing for clients with COPD.

Choice B rationale

Increasing oxygen to 5 liters per minute without proper medical guidance can lead to oxygen toxicity and other complications in COPD patients.

Choice C rationale

Discontinuing prednisone abruptly can lead to adrenal insufficiency and should be tapered off under medical supervision.

Choice D rationale

Decreasing caloric intake can lead to malnutrition, which is detrimental for COPD clients who need adequate nutrition to maintain energy and muscle strength. .

A. I can have clear liquids up to 3 hours before the procedure. B. I can eat as soon as the procedure is completed. C. I might have blood-tinged sputum after the procedure. D. I will receive an injection of radioactive material prior to having the procedure.

Correct Answer is C

Explanation

Choice A rationale

Having clear liquids up to 3 hours before the procedure is incorrect. Clients are generally advised to be NPO (nothing by mouth) for a certain period before a bronchoscopy to prevent aspiration.

Choice B rationale

Eating as soon as the procedure is completed is incorrect. Clients need to wait until their gag reflex has returned before eating or drinking to prevent choking or aspiration.

Choice C rationale

Blood-tinged sputum after the procedure is an expected finding. Bronchoscopy can cause minor irritation and bleeding in the airways, leading to blood-tinged sputum.

Choice D rationale

Receiving an injection of radioactive material prior to the procedure is incorrect. This statement confuses bronchoscopy with other diagnostic tests such as a PET scan. Bronchoscopy involves direct visualization of the airways using a bronchoscope. .
