Order: Dobutamine IV to infuse at 6 mcg/kg/min. It is available as Dobutamine 300 mg in 250 mL D5W. The client weighs 100 kg. Calculate the flow rate in mL/hr. Round to the nearest tenths place where applicable and enter numeric value only (no commas or labels) ________ mL/hr Correct answer: 30.0 Rationale: Step 1 is to calculate the total dosage required per minute mcg per minute = Weight in kg × Dosage (mcg/kg/min) 100 × 6 = 600 mcg/min Step 2 is to calculate the total dosage required per hour mcg per hour = mcg/min × 60 minutes 600 × 60 = 36,000 mcg/hr Step 3 is to convert the hourly mcg dose to milligrams (mg) mg per hour = mcg/hr ÷ 1000 36,000 ÷ 1000 = 36 mg/hr Step 4 is to calculate the concentration of the available solution in mg/mL mg per mL = Total mg ÷ Total mL 300 ÷ 250 = 1.2 mg/mL Step 5 is to calculate the flow rate in mL per hour mL/hr = mg/hr ÷ mg/mL 36 ÷ 1.2 = 30 Step 6 is to round to the nearest tenth 30 = 30.0 Answer: 30.0
