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

Increased respiratory rate is a compensatory mechanism in metabolic acidosis to expel excess carbon dioxide and decrease blood acidity.

Choice B rationale

Positive Trousseau's sign indicates hypocalcemia, not metabolic acidosis. It is seen in patients with low calcium levels.

Choice C rationale

Tingling of the fingers is usually associated with electrolyte imbalances such as hypocalcemia, rather than metabolic acidosis.

Choice D rationale

Dizziness upon standing is typically a sign of orthostatic hypotension, not directly related to metabolic acidosis.

A. BRCA1 mutation B. Race C. First pregnancy at age 25 D. Biopsy result

Correct Answer is ["A","B"]

Explanation

Choice A rationale: A BRCA1 mutation significantly increases the risk of breast cancer. BRCA1 and BRCA2 genes are involved in the repair of DNA damage, and mutations in these genes impair this function, leading to an increased likelihood of developing breast cancer. Women with a BRCA1 mutation have a substantially higher lifetime risk of breast cancer compared to the general population.

Choice B rationale: Race can be a risk factor for breast cancer, as certain racial and ethnic groups have differing incidences of the disease. Native American women, while having a lower overall risk compared to some other groups, may still have unique risk factors that contribute to their likelihood of developing breast cancer. Additionally, healthcare access and cultural factors can influence outcomes.

Choice C rationale: Having the first pregnancy at age 25 is associated with a lower risk of breast cancer compared to women who have their first pregnancy at a later age. Early full-term pregnancies are generally considered protective against breast cancer because they lead to differentiation of breast cells, which may reduce susceptibility to cancerous changes.

Choice D rationale: The biopsy result showing fibroadenoma, a benign breast tumor, does not itself increase the risk of breast cancer. Fibroadenomas are non-cancerous and are common among younger women. While they may require monitoring, they do not indicate a higher risk of malignancy.
