The client with type 1 diabetes mellitus is prescribed to take NPH (Humulin N) insulin at 5 PM each day. The client should be instructed that the greatest risk of hypoglycemia will occur about what time?
1AM while sleeping
PM shortly after lunch
6 PM shortly after dinner
11:00 AM, shortly before lunch
The Correct Answer is A
1 AM while sleeping: NPH insulin, like Humulin N, typically reaches its peak effectiveness about 4-12 hours after administration. Since the client takes it at 5 PM, the time of greatest risk for hypoglycemia is around 1 AM when the insulin's effects are at their peak. This is a critical period for monitoring blood glucose levels.
B. 8 PM shortly after dinner: By 8 PM, the NPH insulin's effectiveness is not at its peak. It's been about 3 hours since administration, and the insulin is still working to lower blood glucose levels. This time frame is not associated with the highest risk of hypoglycemia.
C. 6 PM shortly after dinner: At 6 PM, it's been only about an hour since the client took the NPH insulin. The insulin is just beginning to take effect, and the risk of hypoglycemia is not as high as it would be later in the night.
D. 11:00 AM, shortly before lunch: By 11:00 AM, the effects of the NPH insulin from the previous evening have largely worn off. This time frame is not associated with a high risk of hypoglycemia related to the evening dose of NPH insulin.

Correct Answer is B
Explanation
A. This option corresponds to the blood glucose range of 151-200. However, the patient's current blood glucose level is 264, which falls into the range of 251-300. Therefore, administering 2 units would not be appropriate in this case.
B. The patient's current blood glucose level is 264, which falls into the range of 251-300. According to the sliding scale insulin aspart orders, for this range, 6 units should be administered. This option aligns with the patient's blood glucose level and the prescribed protocol.
C. This option corresponds to the blood glucose range of 351-400. The patient's blood glucose level of 264 does not fall into this range, so administering 10 units would be excessive and potentially lead to hypoglycemia.
D. This option corresponds to the blood glucose range of 201-250. The patient's current blood glucose level is 264, which falls into the range of 251-300. Therefore, administering 4 units would not be sufficient to address the elevated blood glucose level.
Correct Answer is C
Explanation
A. Incorrect. Aging is associated with a decrease in insulin production and a reduction in the speed of insulin release, not an increase.
B. Incorrect. Intolerance of fatty foods is not typically an age-related endocrine change. It may be related to other factors such as digestive issues.
C. Correct. Decreased sensitivity to insulin is a common age-related endocrine change, particularly in individuals with type 2 diabetes mellitus.
D. Incorrect. Lower and prolonged blood glucose levels are not an expected age-related endocrine change. Instead, insulin resistance tends to result in elevated blood glucose levels.
