ممرض يعطي إنسولين ريجيولار و NPH في نفس الحقنة. أي ترتيب صحيح؟

A nurse gives regular and NPH insulin in one syringe. Which sequence is correct?

1. Combine both vials together, then draw from the mixture
2. Draw up the cloudy NPH first, then the clear regular
3. Shake the clear vial vigorously before drawing the dose
4. Draw up the clear regular insulin first, then the cloudy NPH

Answer: D) Draw up the clear regular insulin first, then the cloudy NPH. Clear before cloudy prevents contaminating the regular vial with NPH. NPH is rolled, not shaken. Basal analogues such as glargine are not mixed.
