Correct Answer: D

Rationale: Explaining the use of prescribed medications is crucial because it helps ensure proper management of the child's condition after discharge. While teaching the parents about signs of infection and providing instructions on wound care are important aspects of postoperative care, they are not as critical as ensuring the correct understanding and administration of prescribed medications. Scheduling follow-up appointments is also important but does not directly impact the immediate post-discharge care and medication adherence.

Correct Answer: A

Rationale: Explaining the procedure in simple terms is essential preoperative teaching for a 4-year-old child scheduled for a myringotomy. This approach helps the child understand what will happen during the procedure, reducing anxiety and fear. Encouraging fluid intake is a good general health practice but not directly related to preoperative teaching for this procedure. Allowing the child to play with medical equipment may not be safe or appropriate as it can lead to misunderstanding or fear. Using play therapy can be beneficial but explaining the procedure in simple terms is more direct and effective for preoperative teaching in this case.

Correct Answer: B

Rationale: The correct answer is B: Signs of child abuse. When a nurse observes large welts and scars on a child, it raises concern for possible child abuse. It is crucial for the nurse to assess further for signs of abuse, document findings, and report appropriately to protect the child. Choice A, history of an injury, is not specific to potential abuse and may not provide insight into the current situation. Choice C, presence of food allergies, is not directly related to the observed welts and scars. Choice D, recent recovery from chickenpox, is also unrelated to the signs of abuse and does not impact the immediate assessment of the child's safety.

Scheduling follow-up appointments is also important but does not directly impact the immediate post-discharge care and medication adherence.

Correct Answer: B

Rationale: The priority nursing intervention when caring for a child with nephrotic syndrome is monitoring urine output. This is essential for assessing kidney function and managing the condition effectively. Administering diuretics (Choice A) may be a part of the treatment plan but should not be the priority over monitoring urine output. Administering corticosteroids (Choice C) may also be a treatment for nephrotic syndrome, but monitoring urine output takes precedence. Restricting fluid intake (Choice D) may be necessary in some cases, but it is not the priority intervention compared to monitoring urine output for early detection of changes in kidney function.
