Final answer:
The nurse should administer 50 mg per dose of methylprednisolone (Solu-Medrol) to the child.
Step-by-step explanation:
To calculate the dosage of methylprednisolone (Solu-Medrol) for the child, we need to multiply the child's weight (50 kg) by the dosage per kilogram (2 mg).
2 mg/kg x 50 kg = 100 mg
Since the total daily dosage is divided into two equal doses, we need to divide 100 mg by 2 to get the dosage per dose.
100 mg / 2 = 50 mg per dose
Therefore, the nurse should administer 50 mg per dose of methylprednisolone (Solu-Medrol) to the child.
