- Intermediate-acting (NPH)

- Long-acting (Lantus)

- Regular (Humulin R)

- Short-acting (Novolin R)


"Intermediate-acting (NPH)" is correct. Intermediate-acting insulin has a range of duration that is between the short-acting and long-acting types of insulin. Intermediate insulin, such as NPH, is the only type of insulin that can be added to a short- or rapid-acting insulin to be used as part of combination insulin therapy.

"Long-acting (Lantus)" is incorrect because glargine (Lantus) should never be mixed with any other insulin.

"Regular (Humulin R)" and "Short-acting (Novolin R)" are incorrect because they are both short-acting insulins that cannot be combined with a rapid-acting insulin.
