Final answer:
The nurse would expect the health care provider to order B) Regular insulin to manage the client's high blood sugar levels and symptoms of excessive hunger and thirst.
Step-by-step explanation:
Based on the client's high blood sugar level and symptoms of excessive hunger and thirst, it is likely that the nurse would expect the health care provider to order B) Regular insulin.
Regular insulin is a short-acting insulin that helps lower blood sugar levels by facilitating the uptake of glucose by cells, especially muscle and fat cells. It is commonly used to manage high blood sugar levels in individuals with diabetes.
Orange juice may actually worsen the client's high blood sugar levels due to its high sugar content. NPH insulin is a longer-acting insulin and may not provide immediate relief for the client's symptoms and high blood sugar levels. Lastly, repeating the blood sugar level may be necessary, but it would not address the immediate need for treatment.
