Correct Answer is A

Explanation

A. NPH insulin typically has an onset of 1–2 hours, peaks around 4–12 hours after administration, and lasts about 18–24 hours. Given the 7 a.m. administration, the peak effect—and thus the highest risk for hypoglycemia—would occur roughly between 11 a.m. and 7 p.m., making 2 p.m. the most likely time for hypoglycemia.
B. 5 a.m. is before the insulin peak and unlikely to cause hypoglycemia.
C. 10 a.m. is closer to the onset but may be before peak action.
D. 10 p.m. is typically after the insulin effect has declined.

A. The client needs a consultation with a healthcare provider to evaluate the therapeutic effects of his insulin regimen. B. The client requires further teaching regarding nutritional guidelines. C. The client is experiencing rebound hyperglycemia. D. The client has followed the treatment plan as prescribed.

Correct Answer is D

Explanation

A. A consultation is unnecessary in this context, as the A1C result indicates excellent glucose control.
B. Further teaching is not indicated because the lab result shows the client is likely adhering to nutritional recommendations.
C. Rebound hyperglycemia, such as the Somogyi effect, would likely result in an elevated A1C.
D. An A1C of 5% is within the normal range and suggests that the client's blood glucose levels have been well controlled over the past 2–3 months, indicating adherence to the prescribed treatment plan.
