The elderly client is admitted to the intensive care department with severe Hyperglycemic-Hyperosmolar State (HHS). Which collaborative intervention should the nurse include in the plan of care?

A. Administer intermediate-acting insulin: Intermediate-acting insulin is not used in the treatment of HHS. In HHS, the primary goal is to lower blood glucose levels gradually using short-acting insulin to prevent rapid changes in glucose and fluid shifts. B. Infuse 0.9% Normal Saline intravenously: IV fluids are a critical part of the treatment for HHS. 0.9% Normal Saline is used to correct dehydration and restore circulatory volume, which is a major concern in HHS. The goal is to gradually rehydrate the client while simultaneously lowering blood glucose levels. C. Monitor arterial blood gas results: While monitoring arterial blood gases (ABG) is important for assessing acid-base balance, it is not the priority intervention for HHS. The primary focus should be on correcting hyperglycemia and dehydration first. D. Perform blood glucose checks daily: Blood glucose monitoring should be more frequent than daily in a client with HHS. It is critical to monitor blood glucose levels every hour or as frequently as needed to assess the effectiveness of interventions and guide insulin therapy.
