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: 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: B

Rationale: The priority nursing intervention for a child admitted with bacterial meningitis is isolating the child. Isolation is crucial to prevent the spread of the highly contagious infection to other patients and healthcare workers. Administering antibiotics (Choice A) is important but isolating the child takes precedence to contain the spread of the infection. Monitoring vital signs (Choice C) and administering fluids (Choice D) are essential aspects of care but do not address the immediate need to prevent transmission of the infection.

Correct Answer: C

Rationale: The correct answer is C: 37% to 47%. The normal hematocrit range for a 12-month-old infant is between 37% to 47%, which reflects the expected blood volume and red blood cell levels for this age. Choice A (19% to 32%) and Choice B (29% to 41%) are too low and do not encompass the typical hematocrit range for a healthy 1-year-old. Choice D (42% to 69%) is too high and falls outside the usual hematocrit values for this age group.

Correct Answer: A

Rationale: For a child with a 'slow-to-warm-up' temperament, it is important to choose activities that are less intense and allow for gradual engagement. Reading stories to the child about famous athletes would be the most successful approach as it is less active and more likely to be acceptable to the child's temperament. Choice B and C involve more active and potentially overwhelming activities, which may not suit the child's temperament. Choice D, proposing wrestling and letting the child win, might create a competitive environment that could be counterproductive for a 'slow-to-warm-up' child.
