Which of the following nursing interventions is important for a client scheduled to have a Guaiac Test?

Correct Answer: A

Rationale: The correct answer is A. Turnips, radish, and horseradish are known to cause false-positive results in a Guaiac Test, which is used to detect blood in the stool. Avoiding these foods is crucial to ensure accurate test results. Choice B is incorrect as iron preparation is not directly related to the Guaiac Test. Choice C is incorrect because avoiding meat is not specifically necessary before a Guaiac Test. Choice D is incorrect as caffeine and dark-colored foods can potentially interfere with test results, so they should not be encouraged.

Correct Answer: C

Rationale: The inappropriate action in collecting a midstream clean-catch urine specimen for urine analysis is to collect only 5 to 10 ml of urine. Adequate urine volume of 30 to 60 ml is required for accurate testing. Collecting a small amount like 5 to 10 ml may lead to inaccurate results due to insufficient sample size. It is crucial to follow proper collection techniques, such as discarding the first flow of urine, performing perineal care, and collecting an adequate volume, to ensure reliable test results.

Correct Answer: B

Rationale: Clients who smoke require more vitamin C due to increased oxidative stress and depletion of vitamin C. Smoking leads to higher levels of oxidative stress in the body, which in turn increases the utilization of vitamin C to counteract the damage caused by free radicals. Choices A, C, and D do not directly impact the body's need for vitamin C as smoking does.

Correct Answer: D

Rationale: In this scenario, the correct answer is D) St. John's Wort. St. John's Wort is known to induce liver enzymes, particularly CYP3A4 and P-glycoprotein, which can accelerate the metabolism of certain drugs, including oral contraceptives and antidepressants. This interaction can lead to decreased effectiveness of these medications, potentially resulting in treatment failure or reduced therapeutic benefits. Option A) Iron supplement is not the correct answer because iron supplements do not typically have significant interactions with antidepressants or oral contraceptives. Option B) Garlic is also not the correct answer in this context. While garlic can interact with certain medications, it is not specifically known to interact with antidepressants or oral contraceptives in the same way that St. John's Wort does. Option C) Green tea is not the correct answer either. Green tea is generally considered safe and does not typically have significant interactions with antidepressants or oral contraceptives. Educationally, it is crucial for nurses to be aware of potential drug-herb interactions to ensure the safety and effectiveness of pharmacological treatments for clients. Providing accurate information and counseling on the use of herbal supplements can help prevent adverse effects and optimize patient outcomes. Nurses should always assess for the concurrent use of herbs and medications and educate clients on the importance of discussing all supplements with healthcare providers to avoid harmful interactions.

Correct Answer: D

Rationale: Clinical dietitians and pharmacists are the key members of the healthcare team responsible for monitoring drug-nutrient interactions. Clinical dietitians assess patients' nutritional needs and develop appropriate diets that consider medication effects, while pharmacists provide expertise on medications and their interactions with nutrients. Physicians and nurses are essential healthcare providers but typically do not have the specialized knowledge required to manage drug-nutrient interactions, making choices A, B, and C incorrect.
