A nurse is preparing to administer lidocaine 1.7 mg/min via continuous IV infusion to a client who is pregnant and has a ventricular arrhythmia. Available is lidocaine 1 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.)

Calculate the concentration of the available solution in milligrams per milliliter (mg/mL). Available: 1 g in 250 mL. Convert 1 g to 1000 mg. Concentration (mg/mL) = 1000 mg/250 mL = 4 mg/mL. Calculate the total dose required per hour (mg/hr). Ordered rate: 1.7 mg/min Total dose rate (mg/hr) = 1.7 mg/min×60 min/hr = 102 mg/hr. Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total dose rate (mg/hr) / Concentration (mg/mL) = 102 mg/hr/4 mg/mL = 25.5 mL/hr. Round the answer to the nearest whole number. = 26 mL/hr.
