A client on the medical unit receives regular insulin at 7:00 A.M. The nurse is alert to a possible hypoglycemic reaction by which time?
a. 7:30 A.M.
b. 10:00 A.M.
c. 4:00 P.M.
d. 8:00 P.M.
B
Regular insulin reaches its peak in two to four hours after administration. If the client received regular insulin at 7:00 A.M., the nurse should be alert for a possible hypoglycemic reaction from 9:00 A.M. to 11:00 A.M.
Regular insulin has an onset in 30 minutes.
Intermediate-acting insulin (e.g., NPH insulin), not regular insulin, would peak in six to 12 hours.
The client would not be at risk for a hypoglycemic reaction from regular insulin 13 hours after administration. Long-acting insulin would have an effect this much later after administration.
