Question

Based on 10ml per kg, what is child's dose if child weighs 45lbs? ml?

Answer 1

10 ml / kg

45 # = x kg

45#/ (2.2 #/kg) = 20.45kg

20.45 kg * 10 ml/kg = 204.5 ml

An easy-to-use conversion table is here: http://www.spadepot.com/spacyclopedia/co...

In medicine/pharmacology, we round to the nearest "easiest" number or 200ml. Usually you will want to give the medicine in "divided doses" or a small amount several times a day--usually 4 times a day for most medicine to maintain a constant therapeutic blood level.

200ml / 4 = 50ml per dose

At 15ml per Tablespoon, that's 3 1/3tablespoons per dose.

FYI--AS a doctor, that sounds like a lot to give a small kid to drink! As a parent of a 50# 5-year-old, there's no way you're going to get that in him/her!!

Are you sure the dosage isn't 10 mg (milliGRAMS) /kg?

You'll need to figure out how many mg are in each ml. Most prescriptions are listed as X number of mg per 5ml (or 1 teaspoon). 50 mg per ml is a lot easier to swallow!

Answer 2

The above answers are correct, but I wonder if your question's right. Dosages are normally in mg/kg, and the concentration has to be figured into things. If, for instance, you've misread the label on ibuprofen and want to give 10 mg/kg, with 100 mg/5 ml, there's a difference between the right dose of two teaspoons as opposed to the 6 1/2 ounces you'd get from the technically correct answer.

Answer 3

45 lbs = 20.4 kg ( 1 kg = 2.2 lbs)

Dose is 10 ml per kg so

for 20.4 kg, dose is 204 ml = 200 ml
