A nurse in a provider’s office performs a fecal occult blood test with a positive result on a client.
Which of the following clients may have a false positive result?

A. A client who has a venous stasis ulcer.

A client who has peripheral hematomas.

A client who underwent a barium swallow study.

A client who takes an iron supplement.

Answer and Explanation

The Correct Answer is C

Correct answer: C

A. A client who has a venous stasis ulcer: This is less likely to cause a false positive result. While ulcers can bleed, the fecal occult blood test is designed to detect small amounts of blood in the stool, not necessarily blood from other sources like venous stasis ulcers.

B. A client who has peripheral hematomas: Peripheral hematomas are typically not related to the fecal occult blood test. They generally wouldn’t affect the results unless there was significant bleeding or if the hematomas were a result of an underlying bleeding disorder.

C. A client who underwent a barium swallow study: This is the most likely to cause a false positive result. Barium used in the study can sometimes appear as a false positive on the test due to its interference with the chemical reactions used to detect blood.

D. A client who takes an iron supplement: Iron supplements can actually cause a false negative result rather than a false positive because they may darken the stool and mask the presence of blood.

Correct Answer is A

Explanation

The correct answer is choice A: "I will speak with your provider on your behalf."

Choice A rationale: The principle of advocacy in nursing involves supporting and speaking up for clients to ensure their rights, needs, and preferences are respected. By offering to speak with the provider on the client's behalf, the nurse demonstrates advocacy by actively working to represent the client's interests and facilitate communication between the client and the health care team.

Choice B rationale: While promising to fulfill commitments is an aspect of maintaining professional integrity, it does not directly demonstrate advocacy. Advocacy is more about actively supporting the client's rights and needs rather than personal dedication to fulfilling promises.

Choice C rationale: Maintaining the privacy and confidentiality of client information is essential in nursing practice, but it is not specifically related to advocacy. Privacy is a separate ethical principle that focuses on protecting the client's personal information and upholding their right to privacy.

Choice D rationale: Encouraging clients to make decisions about their health care is important for promoting autonomy. However, advocacy involves actively supporting the client's decisions and ensuring their rights are respected, rather than simply allowing them to make decisions.

A. 1 medium fresh green pear. B. 1 small apple with skin. C. 1 small banana. D. 1 small pink grapefruit.

Correct Answer is D

Explanation

This food has the highest vitamin C content among the four options, with about 80 to 100 mg of vitamin C per fruit.

Vitamin C is a water-soluble vitamin that acts as an antioxidant and helps with wound healing, immune function, collagen synthesis, and iron absorption.

Choice A is wrong because 1 medium fresh green pear has only about 4 to 5 mg of vitamin C per fruit.

Pears are a good source of fiber and potassium, but not vitamin

C. Choice B is wrong because 1 small apple with the skin has only about 8 to 9 mg of vitamin C per fruit.

Apples are a good source of fiber and flavonoids, but not vitamin

C. Choice C is wrong because 1 small banana has only about 10 to 11 mg of vitamin C per fruit.

Bananas are a good source of potassium, magnesium, and vitamin B6, but not vitamin
