A nurse is preparing to administer a client's daily dose of NPH insulin at 0730. The nurse should expect this type of insulin to peak within which of the following timeframes after administration?

A. NPH insulin does have a peak; it is an intermediate-acting insulin. B. NPH insulin typically peaks 6 to 8 hours after administration, which is important for timing meals and monitoring for hypoglycemia. C. A peak of 1 to 2 hours is characteristic of rapid-acting insulin, not NPH. D. A peak of 30 minutes to 1 hour corresponds to short-acting insulin, not intermediate-acting NPH.
