When preparing one syringe containing regular insulin and NPH insulin, which technique is correct?
Correct answer: B. Draw clear insulin before cloudy insulin
- A. Draw cloudy insulin before clear insulin
- B. Draw clear insulin before cloudy insulin
- C. Shake both insulin vials vigorously first
- D. Mix glargine with NPH in the same syringe
Explanation
Regular insulin is clear and NPH insulin is cloudy, so clear insulin is drawn up before cloudy insulin. This prevents NPH from contaminating the regular insulin vial; insulin glargine should not be mixed with other insulins.
