A nurse is preparing to administer clindamycin 10 mg/kg/day PO in three divided doses to a child who weighs 53 lb. Available is clindamycin oral solution 75 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["5.3"]

To calculate the correct dose of clindamycin, we need to follow these steps:

  1. Convert pounds to kilograms:

    • 53 lb * 0.4536 kg/lb = 24 kg

  2. Calculate the daily dose in milligrams:

    • 10 mg/kg/day * 24 kg = 240 mg/day

  3. Calculate the dose per administration:

    • Since the medication is divided into three doses, divide the daily dose by 3:
      • 240 mg/day / 3 = 80 mg/dose

  4. Determine the volume needed from the available concentration:

    • 80 mg * (5 mL / 75 mg) = 5.33 mL

Therefore, the nurse should administer 5.3 mL of clindamycin per dose.

Explanation

To calculate the correct dose of methylprednisolone, we need to follow these steps:

  1. Convert pounds to kilograms:

    • 64 lb * 0.4536 kg/lb = 29 kg

  2. Calculate the daily dose in milligrams:

    • 7 mg/kg/day * 29 kg = 203 mg/day

  3. Calculate the dose per administration:

    • Since the medication is divided into two doses, divide the daily dose by 2:
      • 203 mg/day / 2 = 101.5 mg/dose

  4. Determine the volume needed from the available concentration:

    • 101.5 mg * (1 mL / 20 mg) = 5.075 mL

Therefore, the nurse should administer 5.1 mL of methylprednisolone per dose.
