Calculate the correct amount to be administered per dose. A child is who weighs 55 lb is to receive 0.05 mg of a drug per Kg of body weight per dose. How much of the drug should the child receive for each dose?

First, you need to convert the child's weight from pounds to kilograms. Since 1 kg is approximately 2.2 lbs, you can calculate the weight in kg by dividing the weight in lbs by 2.2. So, 55 lb ÷ 2.2 = 25 kg. Next, multiply the child's weight in kg by the dosage amount: 25 kg × 0.05 mg/kg = 1.25 mg. Therefore, the child should receive 1.25 mg of the drug for each dose. Want to remember this calculation easily? Keep in mind that converting pounds to kilograms can be done by simply dividing the weight by a little more than 2, making it a quick mental math task! Also, avoid the common pitfall of mixing up mg and grams. Always double-check your units when calculating dosages for safety.
