Question

1. the client has an order for mixing two types of insulin. which statement is true when it comes to mixing two types of insulin?

a when mixing insulins, the cloudy (such as nph) insulin should be drawn up into the syringe first.
b when mixing insulins, the clear (such as regular) insulin should be drawn up into the syringe first.
c call the provider as you cannot mix insulin.
d the order doesnt matter when mixing insulins.

Explanation:

When mixing insulins, clear insulin (such as regular) is drawn up first to prevent contamination of the clear insulin vial with cloudy insulin. Cloudy insulins (like NPH) have added substances (e.g., protamine and zinc) that could affect the purity of the clear insulin if the order was reversed. Mixing certain insulins is a standard practice (so option C is incorrect), and the order does matter (so option D is incorrect).

Answer:

B. When mixing insulins, the clear (such as regular) insulin should be drawn up into the syringe first.
