A nurse is preparing to administer milrinone 50 mcg\/kg IV loading dose to a client who weighs 154 lb. Available is milrinone 1 mg\/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. 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 how many mL of milrinone to administer, follow these steps:<\/p>\n\n\n\n

    \n
  1. Convert the client’s weight from pounds to kilograms<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • Weight in pounds: 154 lb<\/li>\n\n\n\n
    • Conversion factor: 1 lb = 0.453592 kg<\/li>\n\n\n\n
    • Weight in kilograms: ( 154 \\, \\text{lb} \\times 0.453592 \\, \\text{kg\/lb} = 69.85 \\, \\text{kg} ) (rounded to two decimal places)<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Calculate the total dose required<\/strong>:<\/li>\n<\/ol>\n\n\n\n
          \n
        • Dosage ordered: 50 mcg\/kg<\/li>\n\n\n\n
        • Weight of the client: 69.85 kg<\/li>\n\n\n\n
        • Total dose (in mcg): ( 50 \\, \\text{mcg\/kg} \\times 69.85 \\, \\text{kg} = 3492.5 \\, \\text{mcg} )<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Convert the dose from mcg to mg<\/strong>:<\/li>\n<\/ol>\n\n\n\n
              \n
            • Conversion factor: 1000 mcg = 1 mg<\/li>\n\n\n\n
            • Total dose (in mg): ( \\frac{3492.5 \\, \\text{mcg}}{1000} = 3.4925 \\, \\text{mg} )<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Determine the volume to administer<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                  \n
                • Concentration available: 1 mg\/mL<\/li>\n\n\n\n
                • Volume required (in mL): ( \\frac{3.4925 \\, \\text{mg}}{1 \\, \\text{mg\/mL}} = 3.4925 \\, \\text{mL} )<\/li>\n<\/ul>\n\n\n\n
                    \n
                  1. Round to the nearest tenth<\/strong>:<\/li>\n<\/ol>\n\n\n\n
                      \n
                    • Volume to administer: 3.5 mL<\/li>\n<\/ul>\n\n\n\n

                      Explanation<\/strong>:<\/p>\n\n\n\n

                        \n
                      1. Weight Conversion<\/strong>: The weight of the client needs to be converted from pounds to kilograms because drug dosages are often calculated based on kilograms.<\/li>\n\n\n\n
                      2. Dose Calculation<\/strong>: The prescribed dose is based on weight in kilograms. By multiplying the dosage (50 mcg\/kg) by the client’s weight in kilograms, the total amount of drug needed in micrograms is determined.<\/li>\n\n\n\n
                      3. Unit Conversion<\/strong>: Since drug concentrations are typically given in mg\/mL but the calculated dose is in mcg, a conversion to milligrams is necessary.<\/li>\n\n\n\n
                      4. Volume Determination<\/strong>: With the concentration provided (1 mg\/mL), dividing the total dose (in mg) by this concentration gives the volume to be administered in milliliters.<\/li>\n\n\n\n
                      5. Rounding<\/strong>: Finally, the answer is rounded to the nearest tenth for practical administration.<\/li>\n<\/ol>\n\n\n\n

                        Thus, the nurse should administer 3.5 mL<\/strong> of milrinone.<\/p>\n","protected":false},"excerpt":{"rendered":"
