A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion. Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag. The client weighs 80 kg. The nurse should set the IV infusion 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.)

Step 1: Calculate the desired dose per minute. Desired dose = 4 mcg/kg/min * 80 kg = 320 mcg/min Step 2: Convert mcg/min to mg/hr. 320 mcg/min * 60 min/hr = 19200 mcg/hr = 19.2 mg/hr Step 3: Calculate the concentration of dopamine in the solution. Concentration = 800 mg / 250 mL = 3.2 mg/mL Step 4: Calculate the volume to be infused per hour. Volume/hr = Dose rate (mg/hr) / Concentration (mg/mL) Volume/hr = 19.2 mg/hr / 3.2 mg/mL = 6 mL/hr Therefore, the nurse should set the IV infusion to deliver 6 mL/hr.
