What is the first step in insulin administration after preparing the vials?

The first step in insulin administration after preparing the vials involves drawing air into the syringe equal to the dose you intend to administer. This initial step is crucial as it prepares the syringe for drawing the appropriate amount of insulin from the vials.

By drawing air into the syringe, you create a vacuum that allows for the easier extraction of insulin from the vial when you withdraw it later. This technique is important for ensuring that the correct dose can be obtained efficiently and reduces the risk of creating a vacuum that could hinder proper dosage retrieval.

The sequence typically involves injecting air into the vials to equalize the pressure before drawing the insulin. Although injecting air into the N (NPH) and R (Regular) insulin vials is indeed part of the preparation process, drawing air into the syringe first sets the stage for the subsequent steps in insulin drawing and administration.
