A nurse is preparing to administer lidocaine 3 mg/min by continuous IV infusion to a client who has a ventricular arrhythmia. Available is lidocaine 2 g in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
