A
When rapid- or short-acting insulin is mixed with intermediate- or long-acting insulin, air should be injected into the intermediate- or long-acting insulin vial first without withdrawal of the medication. Regular insulin is withdrawn first, and then the combined total insulin dose is calculated before the NPH insulin is withdrawn from the vial.
