Neomycin may decrease absorption of which nutrient?

Correct Answer: C

Rationale: The correct answer is C: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.

Correct Answer: B

Rationale: A low-residue diet is appropriate for a patient with Crohn's disease experiencing diarrhea because it helps reduce bowel movements and manage symptoms. Choice A, a high-fiber diet, can exacerbate diarrhea in Crohn's disease due to increased bulk and fermentation in the gut. Choice C, a high-fat diet, may be hard to digest and can worsen symptoms. Choice D, a high-protein diet, can be taxing on the digestive system and may not provide the relief needed for diarrhea in Crohn's disease.

Correct Answer: B

Rationale: In patients with heart failure, a low-sodium diet is most recommended. This type of diet helps manage fluid retention by reducing the amount of sodium in the body. Excess sodium can lead to fluid accumulation, putting additional strain on the heart. High-sodium diets can exacerbate symptoms of heart failure by causing fluid retention and increasing blood pressure. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients and may not address the underlying issues related to fluid balance and heart function.

Correct Answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

Correct Answer: A

Rationale: The correct way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that can occur when fiber intake is suddenly increased. Choice B is incorrect because sudden increases in fiber intake can lead to bloating, gas, and other digestive issues. Choice C is incorrect as decreasing fiber intake abruptly can disrupt bowel regularity and cause constipation. Choice D is incorrect because maintaining a high intake of fiber without considering the patient's current levels can also cause digestive problems.
