A nurse is educating a client with diabetes who has a new prescription for U-300 insulin glargine. Which instruction should the nurse provide regarding administration of this insulin?

A. "Take this medication every 24 hours.": U-300 insulin glargine is a long-acting basal insulin designed to provide steady insulin coverage over 24 hours. Administering it once daily maintains consistent blood glucose control and reduces the risk of hypoglycemia associated with peaks from shorter-acting insulins. B. "Take this medication every 12 hours.": Administering U-300 insulin glargine every 12 hours is unnecessary and could lead to insulin stacking and hypoglycemia, as its pharmacokinetics are designed for once-daily dosing with a relatively flat action profile. C. "Take this medication every 4 hours.": Frequent administration at 4-hour intervals is inappropriate for long-acting insulin. Doing so would significantly increase the risk of severe hypoglycemia due to overlapping insulin effects. D. "Take this medication every 8 hours.": Dosing every 8 hours does not align with the pharmacokinetic profile of U-300 insulin glargine. More frequent dosing could cause cumulative insulin effects, increasing hypoglycemia risk without additional glycemic benefit.
