Correct Answer: C

Rationale: Following surgery for hypertrophic pyloric stenosis (HPS) in infants, it is appropriate to resume regular formula feeding within 24 hours postoperatively to support recovery. This helps maintain adequate nutrition and hydration for the infant. Choice A is incorrect because thickened formula may not be necessary and could potentially cause issues postoperatively. Choice B is incorrect as withholding feedings for the first 24 hours can lead to nutritional deficiencies and delay recovery. Choice D is inappropriate as additional glucose feedings are not typically indicated postoperatively for infants with HPS and may not provide the necessary nutrition needed for recovery.

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.

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: 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.

Correct Answer: D

Rationale: Rapid acting insulin will help lower the elevated blood glucose level quickly.
