Answer (1)
When mixing Regular (clear) insulin and NPH (cloudy) insulin in one syringe, the proper sequence is:1. Inject air into the Regular insulin vial (do not draw up insulin yet).2. Inject air into the NPH insulin vial.3. Draw up Regular insulin first.4. Then draw up NPH insulin.This order prevents contamination of the clear Regular insulin with the cloudy NPH insulin and ensures accurate dosing.
