How many milliliters of medicine should be given to a 24-lb if the recommended dose is 40. mg/kg and the medication comes as a suspension with a cocentration of 400. mg/5mL? 1kg= 2.2kg

I think you made a typo. I suppose you mean 1 kg = 2.2 lbs

24 lb x 1 kg/2.2 lb = approx 10.9 kg but you can do that more accurately.
So the dose is 10.9 kg x 40 mg/kg = approx 436 mg
Then 400 mg/5 mL suspension x ?mL suspension = 436 mg
? mL suspension = xx mL
Check out the math.

Did you know?

Did you know that when calculating the dosage of medicine for a patient, it is important to consider their weight? In this case, if a 24-lb patient requires a medication with a recommended dose of 40 mg/kg, we need to determine the appropriate amount. Since 1 kg is equivalent to 2.2 lbs, we can convert the weight to kilograms by dividing it by 2.2. After that, we can calculate the dosage by multiplying the weight in kg by the recommended dose. Furthermore, it's crucial to check the concentration of the medication, which in this case is 400 mg/5mL. This means that 400 mg is present in every 5 mL of the suspension. By using this information, we can accurately determine the number of milliliters of medicine that should be given to the patient.
