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 ["41210"]
Explanation
- To calculate the number of tablets, divide the prescribed dose by the available dose.
- Prescribed dose: 2 g amoxicillin + 125 mg clavulanate
- Available dose: 1000 mg amoxicillin + 62.5 mg clavulanate
- Number of tablets = (2 g / 1000 mg) + (125 mg / 62.5 mg)
- Number of tablets = 2 + 2
- Number of tablets = 4
- The nurse should administer 4 tablets every 12 hours for 10 days.
Correct Answer is ["100"]
Explanation
- Calculate the infusion rate using the formula: mL/hour = (mL x 60) / minutes
- Plug in the given values: mL/hour = (150 x 60) / 90
- Simplify and solve: mL/hour = 100
- The nurse should program the infusion pump to 100 mL/hour
