A nurse is preparing to administer diphenhydramine 1.25 mg\/kg IM to a child who weighs 68 lb. Available is diphenhydramine injection 50 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 milliliters of diphenhydramine to administer to a child weighing 68 lb, we first need to convert the child’s weight from pounds to kilograms. The conversion factor is 1 kg = 2.2 lb.<\/p>\n\n\n\n

Step 1: Convert Weight<\/h3>\n\n\n\n
    \n
  1. Weight in kg<\/strong>:
    [
    \\text{Weight in kg} = \\frac{\\text{Weight in lb}}{2.2} = \\frac{68}{2.2} \\approx 30.91 \\text{ kg}
    ]<\/li>\n<\/ol>\n\n\n\n

    Step 2: Calculate Dosage<\/h3>\n\n\n\n

    Next, we calculate the dosage of diphenhydramine based on the child’s weight. The prescribed dosage is 1.25 mg\/kg.<\/p>\n\n\n\n

      \n
    1. Total dosage<\/strong>:
      [
      \\text{Total dosage} = 1.25 \\text{ mg\/kg} \\times 30.91 \\text{ kg} \\approx 38.64 \\text{ mg}
      ]<\/li>\n<\/ol>\n\n\n\n

      Step 3: Calculate Volume to Administer<\/h3>\n\n\n\n

      Now, we need to determine how many mL of the diphenhydramine solution (available at 50 mg\/mL) is required to administer the calculated dose.<\/p>\n\n\n\n

        \n
      1. Volume in mL<\/strong>:
        [
        \\text{Volume} = \\frac{\\text{Total dosage}}{\\text{Concentration}} = \\frac{38.64 \\text{ mg}}{50 \\text{ mg\/mL}} \\approx 0.7728 \\text{ mL}
        ]<\/li>\n<\/ol>\n\n\n\n

        Step 4: Rounding<\/h3>\n\n\n\n

        Finally, we round the answer to the nearest tenth as instructed.<\/p>\n\n\n\n

          \n
        1. Rounded volume<\/strong>:
          [
          0.7728 \\text{ mL} \\approx 0.8 \\text{ mL}
          ]<\/li>\n<\/ol>\n\n\n\n

          Final Answer<\/h3>\n\n\n\n

          The nurse should administer 0.8 mL<\/strong> of diphenhydramine.<\/p>\n\n\n\n

          Conclusion<\/h3>\n\n\n\n

          This calculation ensures that the child receives the correct dosage based on their weight, adhering to safe medication administration practices. Proper weight conversion, dosage calculation, and rounding are critical in pediatric nursing to avoid potential medication errors and ensure effective treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"
