Correct Answer: A

Rationale: Encouraging regular physical activity is essential in managing symptoms and improving joint function in juvenile idiopathic arthritis. Physical activity helps maintain joint mobility, muscle strength, and overall function. Providing a high-calorie diet may not be necessary unless there are specific concerns about the child's nutritional status. A low-sodium diet is not typically a priority in the management of JIA unless the child has comorbid conditions requiring sodium restriction. Administering intravenous fluids is not a standard discharge teaching for JIA unless there are specific medical indications necessitating it.

Correct Answer: C

Rationale: The correct answer is C. Excessive thirst (polydipsia) is a common symptom of type 2 diabetes mellitus, indicating high blood glucose levels. This symptom occurs due to the body trying to get rid of excess glucose through urine, leading to dehydration and increased thirst. Choices A, B, and D are incorrect. Choice A is more indicative of a recent viral illness rather than a symptom of diabetes. Choice B, decreased blood pressure, is not typically associated with type 2 diabetes; in fact, diabetes can often lead to hypertension. Choice D, Kussmaul breathing, is more characteristic of diabetic ketoacidosis, which is more common in type 1 diabetes rather than type 2 diabetes.

Correct Answer: D

Rationale: Explaining the use of prescribed medications is crucial as it helps ensure the proper management of the child's condition post-discharge. Understanding how and when to administer medications is essential for the child's recovery. While teaching the parents about signs of infection, providing wound care instructions, and scheduling follow-up appointments are also important aspects of care, ensuring the correct use of prescribed medications takes precedence to prevent complications and promote the child's well-being.

Correct Answer: C

Rationale: Discussing any other observed behaviors can help identify patterns or potential issues, which is crucial for assessing the infant's overall well-being. Option A about accidents and prevention is not pertinent to the situation described. Option B regarding playtime with other children does not address the infant's behavior and potential causes. Option D about food and vitamins is not relevant to the presented scenario and the observed behavior of the infant.

Correct Answer: B

Rationale: The correct answer is B. Participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are incorrect because avoiding aspirin and drugs like ibuprofen, engaging in activities like swimming, and avoiding antihistamines are all appropriate recommendations for a child with idiopathic thrombocytopenia to prevent bleeding episodes and ensure safety.
