(A) This action would further increase the client’s blood sugar. (B) NPH insulin is an intermediate-acting insulin, with an average of 4–6 hours before onset of action.

(C) Regular insulin is the fastest acting-insulin; when given IV, it will immediately act to decrease blood sugar. Regular insulin is given to decrease blood glucose levels by promoting metabolism of glucose, inhibiting lipolysis and formation of ketone bodies. (D) This action would further increase the client’s blood sugar.
