A patient with diabetes has been administered 38 units of NPH insulin at 7:00 AM. By 1:00 PM, the patient has been away from the nursing unit for 2 hours and missed lunch while waiting for a chest X-ray.
What is the most appropriate action for the nurse to prevent hypoglycemia?
A Request that if testing is further delayed, the patient will eat lunch first.
B Plan to discontinue the evening dose of insulin.
C Save the lunch tray for the patient’s later return.
D Send a glass of orange juice to the patient in the diagnostic testing area.
The Correct Answer and Explanation is:
The most appropriate action for the nurse to prevent hypoglycemia in this scenario is:
D. Send a glass of orange juice to the patient in the diagnostic testing area.
Explanation:
NPH (Neutral Protamine Hagedorn) insulin is an intermediate-acting insulin that typically begins to act 1-2 hours after administration, peaks around 4-8 hours, and has a duration of action of 10-16 hours. Since the patient received 38 units of NPH insulin at 7:00 AM, its peak action would be occurring or nearing by 1:00 PM, making it crucial to manage the risk of hypoglycemia effectively.
At 1:00 PM, the patient is at risk of hypoglycemia due to several factors: the peak action of NPH insulin is likely occurring, and the patient missed their lunch. Adequate food intake is essential to balance insulin action and prevent hypoglycemia. Here’s a detailed breakdown of the options:
- A. Request that if testing is further delayed, the patient will eat lunch first. This is a proactive measure but does not address the immediate risk. The patient is already away from the unit and may not return in time to address potential hypoglycemia. Immediate intervention is needed.
- B. Plan to discontinue the evening dose of insulin. This is not an appropriate immediate action. The evening dose of insulin does not address the current issue of missed lunch and potential hypoglycemia resulting from the morning dose. It is also not advisable to adjust insulin doses based on a single missed meal without proper assessment and physician input.
- C. Save the lunch tray for the patient’s later return. While this might help the patient when they return, it does not address the current risk of hypoglycemia. The patient needs immediate intervention to manage their blood glucose level.
- D. Send a glass of orange juice to the patient in the diagnostic testing area. This is the most appropriate action because it provides the patient with a quick source of glucose to help prevent hypoglycemia. Orange juice is an effective intervention because it rapidly increases blood glucose levels. This solution addresses the immediate risk of hypoglycemia while the patient is away from the unit and unable to eat their scheduled meal.
Sending a glass of orange juice ensures that the patient has a readily available source of glucose to counteract the insulin’s effects and maintain safe blood glucose levels until they can return and have a proper meal. This action helps to mitigate the risk of hypoglycemia and ensures the patient’s safety.
