Answer 1 is incorrect because regular insulin is safe to mix with NPH. Answer 2 is incorrect because NPH is safe to mix with Humulin-N, another name for NPH or Lente insulin. Answer 3 is correct because, when Lantus is mixed with other insulins, it is rendered useless. Lantus is a long-acting insulin with no peak.
