A nurse is caring for an adolescent client who has a long history of diabetes mellitus and is being admitted to the emergency department confused, flushed, and with an acetone odor on the breath. Diabetic ketoacidosis is suspected. The nurse should anticipate using which of the following types of insulin to treat this client?
Explanation & Rationale
Choice A reason: Insulin glargine is a long-acting basal insulin used for maintenance therapy. It has a slow onset and is not suitable for acute correction of hyperglycemia or ketoacidosis. Choice B reason: Regular insulin is the preferred choice for treating diabetic ketoacidosis. It has a rapid onset when administered intravenously and allows for tight glucose control and correction of acidosis. It is the standard of care in emergency DKA management. Choice C reason: NPH insulin is intermediate-acting and not used in acute settings. Its delayed onset makes it inappropriate for immediate correction of blood glucose and ketone levels. Choice D reason: Insulin detemir is another long-acting insulin used for basal control. Like glargine, it is not suitable for acute management due to its slow onset and prolonged action.
