Describe the nursing intervention for managing a patient with hyperglycemia.

Administering insulin as prescribed and monitoring blood glucose levels is an essential nursing intervention for managing hyperglycemia. This approach is critical because insulin helps lower blood glucose levels by facilitating the uptake of glucose into the cells, thereby reducing the amount of sugar circulating in the bloodstream. Regular monitoring of blood glucose levels allows the nurse to assess the effectiveness of the insulin and make any necessary adjustments to treatment, ensuring the patient's safety and well-being.

By effectively managing hyperglycemia, the nurse can prevent potential complications, such as diabetic ketoacidosis or long-term damage to organs, which can occur if high blood sugar levels are not appropriately addressed. The combination of insulin administration and blood glucose monitoring forms a foundational aspect of diabetes care and is vital for maintaining glycemic control in patients experiencing hyperglycemic episodes. This intervention directly addresses the problem at hand, unlike the other options, which could potentially worsen the patient's condition.
