A nurse is preparing to administer dobutamine 10 mcg\/kg\/min by continuous IV infusion to a client who weighs 110 lb. Available is dobutamine 250 mg in 250 mL dextrose 5% in water. The nurse should set the IV pump 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.)<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/strong><\/mark><\/p>\n\n\n\n To determine the appropriate IV pump setting for administering dobutamine, we first need to calculate the dosage based on the client’s weight and the prescribed rate of infusion. Here\u2019s how to approach this problem step-by-step:<\/p>\n\n\n\n The client weighs 110 pounds. To convert pounds to kilograms, use the conversion factor 1\u2009kg=2.2\u2009lb1 \\, \\text{kg} = 2.2 \\, \\text{lb}1kg=2.2lb.Weight in kg=110\u2009lb2.2\u2009lb\/kg=50\u2009kg\\text{Weight in kg} = \\frac{110 \\, \\text{lb}}{2.2 \\, \\text{lb\/kg}} = 50 \\, \\text{kg}Weight in kg=2.2lb\/kg110lb\u200b=50kg<\/p>\n\n\n\n The prescribed rate is 10 mcg\/kg\/min. Multiply the weight in kilograms by the infusion rate:Total dosage=50\u2009kg\u00d710\u2009mcg\/kg\/min=500\u2009mcg\/min\\text{Total dosage} = 50 \\, \\text{kg} \\times 10 \\, \\text{mcg\/kg\/min} = 500 \\, \\text{mcg\/min}Total dosage=50kg\u00d710mcg\/kg\/min=500mcg\/min<\/p>\n\n\n\n Since the available solution is in mg, convert micrograms to milligrams:500\u2009mcg\/min=5001000\u2009mg\/min=0.5\u2009mg\/min500 \\, \\text{mcg\/min} = \\frac{500}{1000} \\, \\text{mg\/min} = 0.5 \\, \\text{mg\/min}500mcg\/min=1000500\u200bmg\/min=0.5mg\/min<\/p>\n\n\n\n To find out how many milliliters per hour are required, we first need to determine the concentration of dobutamine in the available solution. The available solution is 250 mg in 250 mL, giving a concentration of:Concentration=250\u2009mg250\u2009mL=1\u2009mg\/mL\\text{Concentration} = \\frac{250 \\, \\text{mg}}{250 \\, \\text{mL}} = 1 \\, \\text{mg\/mL}Concentration=250mL250mg\u200b=1mg\/mL<\/p>\n\n\n\n Now, using the concentration to find out how many mL correspond to the required 0.5 mg\/min:mL\/min=0.5\u2009mg\/min1\u2009mg\/mL=0.5\u2009mL\/min\\text{mL\/min} = \\frac{0.5 \\, \\text{mg\/min}}{1 \\, \\text{mg\/mL}} = 0.5 \\, \\text{mL\/min}mL\/min=1mg\/mL0.5mg\/min\u200b=0.5mL\/min<\/p>\n\n\n\n To convert from mL\/min to mL\/hr, multiply by 60 minutes:mL\/hr=0.5\u2009mL\/min\u00d760\u2009min\/hr=30\u2009mL\/hr\\text{mL\/hr} = 0.5 \\, \\text{mL\/min} \\times 60 \\, \\text{min\/hr} = 30 \\, \\text{mL\/hr}mL\/hr=0.5mL\/min\u00d760min\/hr=30mL\/hr<\/p>\n\n\n\n Thus, the nurse should set the IV pump to deliver 30 mL\/hr<\/strong>. This dosage ensures that the client receives the correct amount of dobutamine for their weight and prescribed infusion rate.<\/p>\n","protected":false},"excerpt":{"rendered":" A nurse is preparing to administer dobutamine 10 mcg\/kg\/min by continuous IV infusion to a client who weighs 110 lb.
