 Administer Dopamine at 10 mcg/kg/min. The pharmacy provides dopamine 800 mg in 250 mL of D5W. Your client weights 85.3 kg. How many mL/hr are you to set the infusion pump? (Round answer to nearest whole number)
Answer and Explanation

The Correct Answer is ["16"]

Step 1: Determine client’s dose in mcg/min

10 mcg/kg/min×85.3 kg=853 mcg/min

Step 2: Convert mcg/min to mg/hr

  • 853 mcg/min=0.853 mg/min

  • Per hour:

0.853 mg/min×60 min/hr=51.18 mg/hr

Step 3: Determine concentration of dopamine solution

  • 800 mg in 250 mL → 800 mg250 mL=3.2 mg/mL

Step 4: Calculate infusion rate in mL/hr

51.18 mg/hr3.2 mg/mL=15.99 mL/hr

Step 5: Round to nearest whole number

≈16 mL/hr
