1. Calculating Dobutamine Infusion Rate
Order: Dobutamine 10 mcg/kg/min
Solution: 250 mg in 500 mL D5W
Patient weight: 154 lb
What is the IV flow rate in mL/hr?
A) 66 mL/hr
B) 70 mL/hr
C) 75 mL/hr
D) 80 mL/hr
Give this one a try later!
Correct Answer: C
🔹 Rationale:
Convert lb to kg:
154÷2.2=70 kg
Calculate mcg/min:
70×10=700 mcg/min
Convert mcg/min to mcg/hr:
700×60=42,000 mcg/
Convert to mL/hr:
42,000÷500=75 mL
