Answer 1 is correct because Lispro is a rapid-acting insulin and should always be drawn up first, to avoid contaminating the bottle of the fast-acting insulin with intermediate-or slow-acting insulin. Answer 2 is incorrect because NPH could contaminate the Lispro. Answer 3 is incorrect because Lantus should never be mixed. It is rendered useless when mixed. Answer 4 is incorrect because Novolin 70/30 is a mixture of long lasting (70 units) with rapid (30 units); therefore, further mixings should be questioned.
