How should insulin dosages be adjusted for this patient to have blood glucose levels within the normal range? Select one: a. Insulin dosages should be given more frequently because the drug will be eliminated at a faster rate. b. Insulin dosages should be increased because cells will be less sensitive to the presence of active insulin c. Insulin dosages should be decreased because the drug will exert its actions at lower concentrations. d. Insulin dosages should be given less frequently because the drug will remain bound to receptors longer.
