A nurse is collecting data from a client who has diabetes mellitus.

The client is confused, flushed, and has an acetone odor on their breath.

The nurse should anticipate a prescription for which of the following types of insulin to treat the client.

A.
Regular insulin.

B.
NPH insulin.

C.
Lispro insulin.

D.
Glargine insulin.

The Correct answer and Explanation is:

The correct answer is A. Regular insulin.

Explanation:

In the scenario provided, the client exhibits signs that are highly indicative of diabetic ketoacidosis (DKA), a serious complication commonly seen in individuals with diabetes mellitus, especially type 1 diabetes. The symptoms of confusion, flushed skin, and the presence of an acetone odor on the breath suggest that the client is in a state of metabolic derangement due to elevated ketone bodies, which occur when the body starts breaking down fat for energy instead of glucose.

Regular insulin is the appropriate choice for several reasons:

1. Rapid Action: Regular insulin, also known as short-acting insulin, has a quick onset of action, typically within 30 minutes. This rapid onset is crucial in emergency situations like DKA, where the immediate correction of hyperglycemia and metabolic acidosis is essential.
2. Intravenous Administration: Regular insulin can be administered intravenously, which is often the preferred route in acute care settings. This allows for precise control of blood glucose levels and rapid adjustments based on the client’s response. In contrast, NPH insulin, lispro insulin, and glargine insulin are generally administered subcutaneously and may not act quickly enough in a critical scenario.
3. Glucose Control: DKA is characterized by high blood glucose levels. Regular insulin is effective in lowering these levels and counteracting the underlying hyperglycemia that contributes to the metabolic crisis.
4. Lack of Duration Consideration: While other insulins, like NPH (intermediate-acting) and glargine (long-acting), have their uses in managing diabetes, they do not provide the rapid and short-term correction needed in DKA.

In summary, the acute presentation of the client and the need for rapid intervention to stabilize blood glucose levels point clearly to the use of regular insulin as the most appropriate treatment in this case
