Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

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.

Correct Answer: A

Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss as a side effect rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss. Choices B, C, and D are incorrect because weight gain, drowsiness, and hypertension are not typically common side effects of metformin.
