Answer 1

The correct order for mixing NPH and regular insulin in the same syringe is to first inject air into the NPH vial, then inject air into the regular insulin vial, followed by withdrawing the NPH dose and then the regular insulin dose.

Step-by-step explanation:

The correct order for mixing NPH and regular insulin in the same syringe is as follows:

1. Inject air (NPH)
2. Inject air (regular)
3. Withdraw dose (NPH)
4. Withdraw dose (regular)

Injecting air into the NPH vial first helps maintain the pressure inside the vial, making it easier to withdraw the correct dose. Injecting air into the regular insulin vial allows for easier withdrawal of the dose as well. Withdrawing the NPH dose before the regular insulin helps prevent the regular insulin from contaminating the NPH vial. Finally, withdrawing the regular insulin dose completes the mixing process.
