People at higher risk for drug-nutrient interactions include:

Correct Answer: D

Rationale: Older men and women are at a higher risk for drug-nutrient interactions due to factors like polypharmacy, changes in metabolism, and physiological changes associated with aging. Infants are less likely to be exposed to a wide range of medications, reducing their risk. People with diabetes and women of childbearing age may have specific nutrient needs or considerations, but they are not typically at a higher risk for drug-nutrient interactions compared to older adults.

Correct Answer: B

Rationale: Short-bowel syndrome usually occurs when more than 50% of the small intestine is surgically removed. This condition results in malabsorption of nutrients and fluids due to the reduced length of the small intestine. Choice A is incorrect because the contraction of longitudinal muscles does not lead to short-bowel syndrome. Choice C is incorrect as short-bowel syndrome is primarily related to the small intestine, not the large intestine. Choice D is incorrect since decreased transit time due to infection or drugs is not a direct cause of short-bowel syndrome.

Correct Answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.

Correct Answer: C

Rationale: The correct answer is C. This statement is true because both prescription and over-the-counter medications, as well as herbal remedies, can interact with food. Choice A is incorrect because over-the-counter medications can also interact with food or nutrients. Choice B is incorrect as not all prescription medications have significant interactions with food. Choice D is incorrect because natural herbal products can also have side effects and interactions with other substances.

Correct Answer: D

Rationale: The correct answer is D, administering phosphate binders. Phosphate binders are a primary intervention for managing hyperphosphatemia as they help by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (choice A) or phosphorus intake (choice B) would exacerbate hyperphosphatemia. Decreasing calcium intake (choice C) is not a primary intervention for managing high phosphorus levels.
