Rationale: In diabetic clients with foot ulcers, strict control of blood glucose levels is essential for promoting wound healing.

Rationale: Daily weighing is the most accurate method to monitor fluid retention in a child with nephrotic syndrome.

Correct Answer: C

Rationale: In this scenario, it is crucial to maintain the client's confidentiality while ensuring her safety.

Correct Answer: D

Rationale: The correct answer is D. A sudden drop in neutrophil count to below 500 indicates severe neutropenia, putting the client at high risk for infections. Neutrophils are essential for fighting off infections, and a significant decrease in their count can compromise the client's immune response. Immediate intervention is necessary to prevent the development of serious infections in the client with neutropenia.
