If the dosage for a medication is 225mg/b, how many grams should a 25-Ib child be given?
To find the dosage in grams for a 25-lb child, we need to convert the weight from pounds to kilograms.
1 lb is equal to 0.453592 kg.
So, a 25-lb child weighs 25 x 0.453592 = 11.3398 kg.
Now we can calculate the dosage in grams:
Dosage in grams = Dosage in mg / 1000
= 225 / 1000
= 0.225 grams.
Therefore, a 25-lb child should be given 0.225 grams of the medication.
To determine how many grams of medication a 25-lb child should be given, we need to convert the weight from pounds to kilograms first.
1 lb = 0.453592 kg
So, the weight of a 25-lb child in kilograms is:
25 lb * 0.453592 kg/lb = 11.3398 kg (rounded to 4 decimal places)
Now, we can calculate the dosage in grams:
Dosage = weight * dosage per kilogram
Dosage = 11.3398 kg * 225 mg/kg
Converting mg to grams:
1 g = 1000 mg
So, the dosage in grams is:
Dosage = (11.3398 kg * 225 mg/kg) / 1000 mg/g
Simplifying:
Dosage = 11.3398 kg * 225 / 1000 g
Calculating:
Dosage = 2.551955 g (rounded to 6 decimal places)
Therefore, a 25-lb child should be given approximately 2.552 grams of the medication.
