Problem
A client in the emergency department is being treated with intravenous (IV) amiodarone for recurrent ventricular tachycardia. After the initial bolus, the nurse is programming the IV pump to deliver the maintenance dose to the client. The order is for 360 mg of amiodarone over the next 6 hours at a rate of 1 mg/min. The concentration of the solution is 900 mg of amiodarone to 500 mL of D5W. At which rate (in mL/hour) should the nurse program the IV pump to administer the maintenance infusion?
