Which of the following drugs contribute to peptic ulcers?

Correct Answer: D

Rationale: The correct answer is D: Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs are known to contribute to peptic ulcers by affecting the gastric mucosa. Choice A, Antacids, actually help to alleviate symptoms of peptic ulcers by neutralizing stomach acid. Choice B, Certain antibiotics, are used to treat H. pylori infections, a common cause of peptic ulcers. Choice C, Cholesterol-lowering medications, do not contribute to peptic ulcers.

Correct Answer: C

Rationale: The correct answer is C. Neomycin can interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K. Choice A is incorrect because neomycin does not affect the absorption of iron, copper, and zinc. Choice B is incorrect as neomycin does not impact the absorption of protein and amino acids. Choice D is also incorrect as neomycin does not decrease the absorption of water-soluble vitamins like vitamin C and the B vitamins.

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-residue diet is the appropriate dietary recommendation for a patient with Crohn's disease experiencing diarrhea. This diet helps reduce bowel movements and manage diarrhea by limiting the intake of foods that are harder to digest. High-fiber diets (Choice A) may worsen diarrhea due to increased bulk in the stool. High-fat diets (Choice C) can be harder to digest and may exacerbate symptoms. High-protein diets (Choice D) are not specifically recommended for managing diarrhea in Crohn's disease.

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.
