Correct Answer: A

Rationale: Increasing physical activity helps improve insulin sensitivity and can prevent or delay the onset of type 2 diabetes in children. Regular physical activity is a key component in managing weight and reducing the risk of chronic diseases. Decreasing physical activity (Choice B) would not be beneficial in reducing the risk of type 2 diabetes. Testing each child's urine monthly (Choice C) is not directly related to preventing type 2 diabetes. Teaching parents to avoid administering aspirin to their child (Choice D) is important for Reye's syndrome prevention but not directly related to reducing the risk of type 2 diabetes.

Correct Answer: C

Rationale: The most appropriate approach when performing a physical assessment on a toddler is to use minimum physical contact initially. This helps gain the toddler's cooperation and reduces their distress. Performing traumatic procedures last is crucial as they are likely to upset the child and should be handled with care. Demonstrating the use of equipment may be complex for toddlers to understand, so it is not the most appropriate initial approach. Proceeding systematically in a head-to-toe direction is a good practice but using minimum physical contact initially is more important to establish trust and cooperation with the toddler.

Correct Answer: C

Rationale: At 5 months, infants typically can turn from their abdomen to their back. Rolling from back to abdomen and sitting erect without support occur later.

Correct Answer: D

Rationale: The correct answer is D: 'Avoid giving citrus juice.' Citrus juice can irritate the throat after a tonsillectomy, so it should be avoided. Choice A is incorrect because blowing the nose gently is not a recommended intervention following a tonsillectomy. Choice B is incorrect as mucus in emesis is not uncommon postoperatively and does not necessarily require physician notification. Choice C is incorrect as positioning the child supine immediately postoperatively can increase the risk of airway obstruction and should be avoided.

Correct Answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.
