Correct Answer: D

Rationale: Older men and women are at higher risk for drug-nutrient interactions due to factors such as polypharmacy and physiological changes. Polypharmacy, common in older adults, increases the likelihood of interactions between drugs and nutrients. Physiological changes that occur with aging can affect how drugs and nutrients are absorbed, distributed, metabolized, and excreted in the body. Infants, people with diabetes, and women of childbearing age are not typically considered high-risk groups for drug-nutrient interactions compared to older adults.

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: Building rapport with the child is essential to establish trust and cooperation during the assessment. Admiring the child may not be appropriate in a professional setting and might not contribute significantly to the assessment. Taking the child's temperature is a routine part of the assessment but may not be the most critical action in this scenario. Obtaining an interpreter is crucial to ensure effective communication between the healthcare team and the child and their mother, especially considering potential language barriers.

Correct Answer: C

Rationale: The correct answer is C because epistaxis and headache in a client with hypertension are signs of a hypertensive crisis that necessitate immediate intervention. Choice A is incorrect as constipation in a client with an abdominal aortic aneurysm, while important, does not indicate an immediate crisis. Choice B is incorrect as a client on bed rest ambulating to the bathroom is a positive sign. Choice D is incorrect because a decreased pedal pulse in arterial occlusive disease should be addressed promptly, but it does not indicate an acute emergency like a hypertensive crisis.

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.
