MD order: 25mg/kg of medication

Question

Available: 100mg/10mL
Child’s weight:48lbs
How many milliliters will you administer per dose? Show all work

Answer 1

To calculate the dose in milliliters, we need to convert the child's weight from pounds to kilograms:

48 lbs * 1 kg / 2.2046 lbs = 21.7724 kg (approximately 21.8 kg)

Now, we can calculate the dose in milligrams:

25 mg/kg * 21.8 kg = 545 mg

Since the available medication strength is 100mg/10mL, we can set up a proportion to find the volume (in mL) needed for the dose:

100 mg x mL
------- = -----
10 mL 545 mg

Cross-multiplying, we get:

100 mg * 545 mL = 10 mL * x

54500 mg = 10 mL * x

Dividing both sides by 10 mL, we find:

x = 54500 mg / 10 mL

x = 5450 mL

Therefore, you will need to administer 5450 mL per dose.
