Which insulin can be mixed according to nursing guidelines?

Mixing insulins can be an essential aspect of diabetes management, allowing for both rapid-acting and short-acting insulin to be administered together for optimal glycemic control. In this case, the correct answer highlights insulins that are compatible for mixing according to nursing guidelines.

Insulin aspart and insulin lispro are both rapid-acting insulins, and regular insulin is a short-acting insulin. They can safely be mixed in the same syringe due to their similar pH levels and their time of action. Mixing these insulins allows for immediate coverage of blood glucose spikes after meals while also providing a baseline level of insulin from the regular insulin.

On the other hand, insulin glargine and insulin detemir are long-acting insulins and are typically not mixed with other insulins in the same syringe, as this can alter their pharmacokinetics and delivery. Additionally, insulin zinc is not commonly used today and would not typically be mixed with other insulins.

Hence, the combination listed in the correct choice supports both safety and efficacy when it comes to insulin administration as per current nursing practices and guidelines.
