The client is admitted with hyperglycemic hyperosmolar nonketonic (HHNK) coma. Which action should the nurse take to treat the symptoms associated with \(\mathrm{HHNK}\) ? A. Administer oxygen by nasal cannula B. Provide adequate fluids C. Offer a carbohydrate D. Administer an oral antidiabetic medication

Hyperglycemic hyperosmolar nonketonic (HHNK) coma is a condition characterized by extremely high blood sugar levels, dehydration, and an altered level of consciousness. It usually occurs in individuals with type 2 diabetes and can be life-threatening if not treated promptly.

A. Administer oxygen by nasal cannula: Oxygen therapy can help in some cases, but it is not the primary treatment for HHNK coma. B. Provide adequate fluids: Fluid replacement is essential in treating HHNK coma, as dehydration is a major issue in this condition. Rehydrating the patient will help balance the electrolytes and lower the blood sugar levels. C. Offer a carbohydrate: Offering a carbohydrate would not help in this situation, as the primary issue in HHNK coma is too high blood sugar levels. Adding more carbohydrates would only worsen the condition. D. Administer an oral antidiabetic medication: Oral antidiabetic medications might help in managing diabetes, but they are not the primary treatment for HHNK coma. Immediate attention should be given to fluid replacement and insulin therapy.

Based on the analysis of each option, the best action for the nurse to take to treat the symptoms associated with HHNK coma is to provide adequate fluids (Option B). This will help to rehydrate the patient and address the major issue of dehydration in this condition.
