A Physician orders amiodarone 1 mg/min for six hours, then 0.5 mg/min thereafter. The patient’s weight is 156 lbs. The concentration of the IV bag comes as 1.8 mg per ml. Calculate the infusion rate in mL/hr.

  1. 33.33mls/hr then /16.67mls/hr
  2. 60mls/hr then 30mls/hr
  3. 30mls/hr then 15mls/hr
