Final answer:
The nurse should administer prescribed insulin to lower the client's high blood glucose level. Coordination of insulin administration with meal times is important to manage the client's type 1 diabetes effectively and to prevent potential hypoglycemia.
Step-by-step explanation:
In the scenario where a client with type 1 diabetes has a blood glucose level of 322 mg/dL, the nurse should administer the prescribed insulin doses to bring the client's blood sugar level down as it is considerably higher than the normal fasting glucose range (70-130 mg/dL). Insulin therapy is essential in managing type 1 diabetes as it helps in the transport and storage of glucose, aiding in the normalization of blood glucose levels.
It is important to coordinate insulin administration with meals to prevent hypoglycemia. Since the client's breakfast is expected to arrive soon, the regular insulin can be given prior to the meal, as it starts working quickly. The NPH insulin, which is intermediate-acting, can be administered at a scheduled time that aligns with the client's insulin regimen to provide a basal level of insulin coverage throughout the day.
Furthermore, the blood glucose will need to be monitored after the insulin is administered, to ensure that it returns to within the normal range and to assess the effectiveness of the insulin doses given.
