A nurse is preparing to administer dopamine hydrochloride 4 mcg\/kg\/min via continuous infusion.<\/p>\n\n\n\n

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To determine the correct IV infusion rate for administering dopamine hydrochloride, follow these steps:<\/p>\n\n\n\n

    \n
  1. Calculate the Total Dose Required per Minute:<\/strong>
    • The client’s weight is 80 kg.<\/li>
    • The prescribed dosage is 4 mcg\/kg\/min.<\/li><\/ul>First, calculate the total dose required per minute:Dose\u00a0per\u00a0minute=Weight\u00a0(kg)\u00d7Dose\u00a0(mcg\/kg\/min)\\text{Dose per minute} = \\text{Weight (kg)} \\times \\text{Dose (mcg\/kg\/min)}Dose\u00a0per\u00a0minute=Weight\u00a0(kg)\u00d7Dose\u00a0(mcg\/kg\/min) Dose\u00a0per\u00a0minute=80\u00a0kg\u00d74\u00a0mcg\/kg\/min=320\u00a0mcg\/min\\text{Dose per minute} = 80 \\text{ kg} \\times 4 \\text{ mcg\/kg\/min} = 320 \\text{ mcg\/min}Dose\u00a0per\u00a0minute=80\u00a0kg\u00d74\u00a0mcg\/kg\/min=320\u00a0mcg\/min<\/li>\n\n\n\n
    • Convert the Dose into mg per Minute:<\/strong>
      • Since 1 mg = 1000 mcg, convert the dose from micrograms to milligrams:<\/li><\/ul>Dose\u00a0in\u00a0mg\/min=Dose\u00a0in\u00a0mcg\/min1000\\text{Dose in mg\/min} = \\frac{\\text{Dose in mcg\/min}}{1000}Dose\u00a0in\u00a0mg\/min=1000Dose\u00a0in\u00a0mcg\/min\u200b Dose\u00a0in\u00a0mg\/min=320\u00a0mcg\/min1000=0.32\u00a0mg\/min\\text{Dose in mg\/min} = \\frac{320 \\text{ mcg\/min}}{1000} = 0.32 \\text{ mg\/min}Dose\u00a0in\u00a0mg\/min=1000320\u00a0mcg\/min\u200b=0.32\u00a0mg\/min<\/li>\n\n\n\n
      • Determine the Concentration of the Solution:<\/strong>
        • The available solution contains 800 mg of dopamine in 250 mL of solution.<\/li><\/ul>Find the concentration of the solution in mg\/mL:Concentration=Total\u00a0mgTotal\u00a0volume\u00a0(mL)\\text{Concentration} = \\frac{\\text{Total mg}}{\\text{Total volume (mL)}}Concentration=Total\u00a0volume\u00a0(mL)Total\u00a0mg\u200b Concentration=800\u00a0mg250\u00a0mL=3.2\u00a0mg\/mL\\text{Concentration} = \\frac{800 \\text{ mg}}{250 \\text{ mL}} = 3.2 \\text{ mg\/mL}Concentration=250\u00a0mL800\u00a0mg\u200b=3.2\u00a0mg\/mL<\/li>\n\n\n\n
        • Calculate the Infusion Rate in mL\/min:<\/strong>Using the concentration and the required dose per minute, calculate the infusion rate:Infusion\u00a0rate\u00a0(mL\/min)=Dose\u00a0in\u00a0mg\/minConcentration\u00a0(mg\/mL)\\text{Infusion rate (mL\/min)} = \\frac{\\text{Dose in mg\/min}}{\\text{Concentration (mg\/mL)}}Infusion\u00a0rate\u00a0(mL\/min)=Concentration\u00a0(mg\/mL)Dose\u00a0in\u00a0mg\/min\u200b Infusion\u00a0rate\u00a0(mL\/min)=0.32\u00a0mg\/min3.2\u00a0mg\/mL=0.1\u00a0mL\/min\\text{Infusion rate (mL\/min)} = \\frac{0.32 \\text{ mg\/min}}{3.2 \\text{ mg\/mL}} = 0.1 \\text{ mL\/min}Infusion\u00a0rate\u00a0(mL\/min)=3.2\u00a0mg\/mL0.32\u00a0mg\/min\u200b=0.1\u00a0mL\/min<\/li>\n\n\n\n
        • Convert the Infusion Rate to mL\/hr:<\/strong>To convert the rate to mL\/hr, multiply by the number of minutes in an hour:Infusion\u00a0rate\u00a0(mL\/hr)=0.1\u00a0mL\/min\u00d760\u00a0min\/hr=6\u00a0mL\/hr\\text{Infusion rate (mL\/hr)} = 0.1 \\text{ mL\/min} \\times 60 \\text{ min\/hr} = 6 \\text{ mL\/hr}Infusion\u00a0rate\u00a0(mL\/hr)=0.1\u00a0mL\/min\u00d760\u00a0min\/hr=6\u00a0mL\/hr<\/li>\n<\/ol>\n\n\n\n

          Thus, the correct IV infusion rate to deliver the prescribed dose of dopamine hydrochloride is 6 mL\/hr<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
