calculation than the preceding dosage rules bases the dosage on a given amount of drug per pound or kilogram of body weight. NOTE: Round off all body weights in kilograms to the nearest whole number. Example: The parental dose of erythromycin injection is 10 mg/kg/24 hours. Calculate the daily dose of this drug for a 44-pound child. (1) Step 1. Convert 44 pounds to kilograms. 44 pounds/2.2 = 20 kilograms (2) Step 2. Multiply the client’s weight by the dose. Childs Dose = 20 kg 10 mg/kg = 200 mg/24

for protein is based on an individual’s body weight. Most healthy adults need 0.8 grams of protein for every kilogram (kg) of body weight (see Chapter 6‚ pages 242 - 243). In general‚ Americans are either meeting or exceeding their protein needs. Determine YOUR protein requirements by converting your body weight from pounds to kilograms and multiplying by 0.8. There are 2.2 kilograms in a pound (so your weight in kg should be a LOWER number than your weight in lbs). SHOW YOUR WORK for full
