Why are hospital patients at greater risk for drug-nutrient interactions than they used to be?

Correct Answer: A

Rationale: The correct answer is A. Hospitalized patients are at greater risk for drug-nutrient interactions because they are more acutely ill, often having multiple conditions and treatments that increase the risk of such interactions. Choice B is incorrect as hospital routines interfering with medication timing are not directly related to drug-nutrient interactions. Choice C is incorrect as the toxicity and side effects of drugs do not necessarily relate to interactions with nutrients. Choice D is incorrect as shared responsibility for monitoring does not directly contribute to the increased risk of drug-nutrient interactions in hospitalized patients.

Correct Answer: B

Rationale: A low-sodium diet is most recommended for patients with heart failure. This type of diet helps manage fluid retention by reducing the amount of sodium in the body, which in turn decreases the workload on the heart. High-sodium diets can lead to fluid retention and worsen heart failure symptoms. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients as the focus is primarily on controlling sodium intake.

Correct Answer: C

Rationale: Zinc supplementation is often used to manage mucositis in patients receiving chemotherapy. Zinc has been shown to aid in the healing process of mucositis. Vitamin E (Choice A) is not typically used to manage mucositis associated with chemotherapy. Vitamin B12 (Choice B) is essential for nerve function and the formation of red blood cells, but it is not primarily used to manage mucositis. Calcium (Choice D) is important for bone health and nerve function but is not specifically used to manage mucositis.

Correct Answer: A

Rationale: The best way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that may arise from a sudden increase in fiber intake. Choice B is incorrect because increasing intake suddenly can lead to digestive issues. Choice C is incorrect as decreasing fiber intake abruptly may not be necessary and can impact overall health. Choice D is incorrect as maintaining a high intake without considering the patient's current intake level can also cause digestive problems.
