When does short-bowel syndrome usually occur?

Correct Answer: B

Rationale: Short-bowel syndrome typically occurs when more than 50% of the small intestine is surgically removed. This condition leads to malabsorption issues due to the reduced length of the intestine for absorption. Choices A, C, and D are incorrect because short-bowel syndrome specifically relates to the insufficient length of the small intestine, not the contraction of longitudinal muscles, surgical removal of the large intestine, or decreased transit time due to infection or drugs.

Correct Answer: C

Rationale: The correct answer is C. This statement is true because both prescription medications and over-the-counter medications, along with 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 misleading because herbal products are not always safe, as they can have side effects and interact with other medications.

Correct Answer: D

Rationale: Administering phosphate binders is a primary intervention for managing hyperphosphatemia. Phosphate binders work by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (Choice A) is not a primary intervention for hyperphosphatemia and can actually exacerbate the condition by potentially raising calcium levels. Increasing phosphorus intake (Choice B) is contraindicated in hyperphosphatemia. Decreasing calcium intake (Choice C) may help manage hypercalcemia but is not the primary intervention for hyperphosphatemia.

Correct Answer: A

Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss in some individuals. Choices B, C, and D are incorrect. Weight gain is not a typical side effect of metformin. Drowsiness and hypertension are also not commonly associated with metformin use.

Correct Answer: A

Rationale: The correct answer is A: Red meat. Red meat is high in purines, which can exacerbate gout attacks. Gout is a form of arthritis that occurs when high levels of uric acid in the blood lead to the formation of urate crystals in the joints. Purine-rich foods can increase uric acid levels, leading to gout symptoms. Chicken and fish are lower in purines compared to red meat, making them better choices for individuals with gout. Dairy products are generally considered safe for gout patients and may even have a protective effect against gout.
