Novolin 30/70 is a mixture of which types of insulin?

• A. Regular insulin and isophane insulin (NPH)
• B. Regular insulin and lispro
• C. Isophane insulin and glargine
• D. Regular insulin and detemir

Answer: (A)

Novolin 30/70 is a premixed insulin formulation that combines a short-acting insulin with an intermediate-acting one. The 30/70 ratio means 30% regular (short-acting) insulin and 70% isophane insulin, also known as NPH (intermediate-acting). The regular insulin provides a quick onset to control rise in blood glucose after meals, while the NPH portion supplies longer basal coverage to help maintain glucose levels between meals and overnight. This combination is distinct from mixes that pair regular with a long-acting insulin or with a rapid-acting insulin, which is why the correct pairing is regular insulin and isophane (NPH).
