Dobutamine 500 mg in 250 mL D5W at 5 mcg\/kg\/min via IV pump. Patient weighs 152 lbs. How many mL\/hour should the patient receive?<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n To calculate how many mL\/hour the patient should receive, we need to work through the steps carefully. Here’s how to approach this:<\/p>\n\n\n\n The patient weighs 152 lbs. To convert pounds to kilograms, we use the conversion factor:<\/p>\n\n\n\n [ So, the patient’s weight in kilograms is:<\/p>\n\n\n\n [ The order specifies that the patient should receive 5 mcg\/kg\/min. To calculate the dose in mcg\/min, we multiply the patient\u2019s weight in kilograms by the dose rate:<\/p>\n\n\n\n [ Thus, the patient needs to receive 344.75 mcg\/min.<\/p>\n\n\n\n The concentration of the solution is 500 mg of dobutamine in 250 mL of D5W. First, convert 500 mg to mcg (since 1 mg = 1000 mcg):<\/p>\n\n\n\n [ Now, divide the total number of mcg by the volume of the solution to find the concentration in mcg\/mL:<\/p>\n\n\n\n [ Thus, the concentration is 2000 mcg\/mL.<\/p>\n\n\n\n We know the patient needs 344.75 mcg\/min. To determine how many mL of the solution should be administered to deliver that dose, we use the concentration (2000 mcg\/mL):<\/p>\n\n\n\n [ Now, convert this rate to mL\/hour:<\/p>\n\n\n\n [ Thus, the patient should receive 10.34 mL\/hour<\/strong>.<\/p>\n\n\n\n The correct infusion rate is 10.34 mL\/hour<\/strong>.<\/p>\n\n\n\n This calculation ensures that the patient receives the correct dosage based on their weight, the medication concentration, and the desired rate of infusion.<\/p>\n","protected":false},"excerpt":{"rendered":" Dobutamine 500 mg in 250 mL D5W at 5 mcg\/kg\/min via IV pump.
