Final answer:
To determine how many milliliters (mL) of Solumedrol the nurse must administer to a child weighing 20kg, we need to calculate the total dose and then divide it by the concentration of Solumedrol.
Step-by-step explanation:
To determine how many milliliters (mL) of Solumedrol the nurse must administer, we need to perform the following calculation:Step 1: Calculate the total dose of Solumedrol needed by multiplying the child's weight (20 kg) by therecommended dosage (3 mg/kg):Total Dose = 20 kg * 3 mg/kg = 60 mgStep 2: Calculate the number of milliliters needed by dividing the total dose (60 mg) by the concentration of Solumedrol (125 mg/2 mL):Number of mL = 60 mg / (125 mg/2 mL) = 4.8 mL (rounded to 2 decimal places)Therefore, the nurse must administer 4.8 mL of Solumedrol to the child.
The question requires a calculation of the dosage of medication in milliliters (ml) to be administered to a child based on their weight. The dosage prescribed is Solumedrol 3mg/kg for a child weighing 20kg. With Solumedrol available at a concentration of 125 mg per 2 ml, we need to calculate the total dosage in milligrams and then convert that to the volume in milliliters.
