A nurse is preparing to administer regular insulin 0.1 unit/kg/hr via continuous IV infusion to a client who weighs 70 kg. Available is regular insulin 100 units in 0.9% sodium chloride 100 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 total dose of regular insulin to be administered per hour (units/hr). Ordered rate: 0.1 unit/kg/hr Patient weight: 70 kg Total dose rate (units/hr) = 0.1 unit/kg/hr×70 kg = 7 units/hr. Calculate the concentration of the available solution in units per milliliter (units/mL). Available concentration: 100 units in 100 mL Concentration (units/mL) = 100 units/100 mL = 1 unit/mL. Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total dose rate (units/hr) / Concentration (units/mL) = 7 units/hr/1 unit/mL = 7 mL/hr.
