A child who weighs 42 kg receives a prescription for methylprednisolone succinate 1.5 mg/kg/day intravenously in divided doses every 6 hours. The medication is available in 40 mg/mL vials. How many mL should the nurse administer with each dose?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
To calculate the amount of methylprednisolone succinate that the child needs, we first need to multiply the child's weight by the prescribed dose. This gives us:
42 kg x 1.5 mg/kg/day = 63 mg/day
Since the medication is given in divided doses every 6 hours, we need to divide the daily dose by 4 to get the dose per administration. This gives us:
63 mg/day / 4 = 15.75 mg/dose
To convert the dose from mg to mL, we need to use the concentration of the medication, which is 40 mg/mL. This means that for every 1 mL of solution, there are 40 mg of methylprednisolone succinate. To find out how many mL are equivalent to 15.75 mg, we need to divide the dose by the concentration. This gives us:
15.75 mg / 40 mg/mL = 0.39375 mL
Since we need to round to the nearest tenth, the final answer is:
0.4 mL

Correct Answer is ["700"]
Explanation
- Calculate the total volume of normal saline: 30 mL/kg x 70 kg = 2100 mL
- Divide the total volume by the infusion time: 2100 mL / 3 hours = 700 mL/hour
- Program the infusion pump to deliver 700 mL/hour
Correct Answer is ["0.5"]
Explanation
- Calculate the dose of dalteparin in units: 60 kg x 200 units/kg = 12,000 units - Calculate the volume of dalteparin in mL: 12,000 units / 25,000 units/mL = 0.48 mL
- Round the volume to the nearest tenth: 0.5 mL
- The nurse should administer 0.5 mL of dalteparin subcutaneously once a day
