The correct answer is choiceD.

Choice A rationale:

Introducing a regular diet is not the immediate priority for a child with severe diarrhea.The focus should be on stabilizing the child’s condition before reintroducing regular foods.

Choice B rationale:

Maintaining fluid therapy is important, but it is part of the broader goal of managing fluid balance.It is not the first step in addressing severe diarrhea.

Choice C rationale:

Rehydration is crucial, but it falls under the broader category of assessing and managing fluid balance.Ensuring the child is properly hydrated is part of the overall assessment.

Choice D rationale:

Assessing fluid balance is the priority action. This involves evaluating the child’s hydration status, monitoring for signs of dehydration, and ensuring that fluid therapy is appropriately managed.This step is critical to prevent complications from severe diarrhea.

Choice A rationale

Allowing the client to rest in a supine position during feeding should prompt the charge nurse to intervene. The client should be in an upright position during feedings and for an hour afterwards to prevent aspiration.

Choice B rationale

Irrigating the NG tube with tap water after feeding is a standard practice. This helps to keep the tube patent and prevent blockages.

Choice C rationale

Administering the feeding through a syringe barrel by gravity is a common method for giving intermittent tube feedings. This method allows for controlled administration of the feeding.

Choice D rationale

Initiating the feeding after aspirating 50 ml of gastric residual is a standard practice. Checking gastric residual volume before feedings helps to assess gastric emptying and tolerance to the feeding.
