A client is scheduled to receive 15 units of NPH insulin subcutaneously at 0730. At what time would the client most likely become hypoglycemic?

Rationale: A. 1000: This time corresponds to approximately 2.5 hours after the 0730 NPH insulin injection. NPH insulin typically has an onset of 1–2 hours, so the glucose-lowering effect is beginning but not yet at its peak, making hypoglycemia less likely at this point. B. 1300: NPH insulin usually peaks 4–6 hours after administration. For a 0730 dose, the peak effect would occur around 1130–1330, making 1300 the time when the client is most at risk for hypoglycemia due to maximal insulin activity. C. 1900: By this time, approximately 12 hours post-injection, the NPH insulin’s effect is declining. While some residual insulin activity may remain, the risk of hypoglycemia is much lower compared with the peak period. D. 1600: This is roughly 8.5 hours after the morning NPH dose, which is past the peak action period. The insulin effect is tapering off, so the likelihood of hypoglycemia is reduced compared with the 4–6 hour peak window.
