Solumedrol 1.5 mg/kg is ordered for a child weighing 50 lb. Solumedrol is available as 75 mg / 1 mL is available. How many mL must the nurse administer?

ordered/have =volume per have

50 divide by 2.2 to covert to kg time 1.5 mg ordered
22.73*1.5 =34*1/75
0.454 ml

50lb = 22.73kg

so, you will need 1.5*22.73 = 34.1 mg

. . .

0.454ml

ordered/have =volume per have

50 divide by 2.2 to covert to kg time 1.5 mg ordered

To determine how many mL of Solumedrol the nurse must administer, we can follow these steps:

Step 1: Convert the child's weight from pounds to kilograms.
To convert pounds to kilograms, divide the weight in pounds by 2.2046.
In this case, the child weighs 50 pounds, so we'll divide 50 by 2.2046:
50 lb ÷ 2.2046 = 22.68 kg (rounded to 2 decimal places)

Step 2: Calculate the total dosage of Solumedrol needed.
Multiply the child's weight in kilograms by the prescribed dose of Solumedrol per kilogram. In this case, the prescribed dose is 1.5 mg/kg.
22.68 kg × 1.5 mg/kg = 34.02 mg (rounded to 2 decimal places)

Step 3: Determine the volume of Solumedrol needed.
Now that we know the total dosage needed (34.02 mg), we can determine the volume of Solumedrol required.
Solumedrol is available as 75 mg / 1 mL.
To find the volume in milliliters (mL), we'll divide the total dosage (34.02 mg) by the concentration (75 mg/mL):
34.02 mg ÷ 75 mg/mL ≈ 0.45 mL (rounded to 2 decimal places)

Therefore, the nurse must administer approximately 0.45 mL of Solumedrol to the child.
