A certain medicine requires 5 mg per 30 kg of weight.
How much medicine is required for a patient that weighs 271 pounds?
dosage=5mg * (271llbs*2.2kg/lb)/30kg
= 5*271/(2.2*30) mg
To calculate the amount of medicine required for a patient weighing 271 pounds, we need to convert their weight from pounds to kilograms. Here's how you can do it:
Step 1: Convert pounds to kilograms
1 pound is approximately equal to 0.453592 kilograms. So, to convert 271 pounds to kilograms, multiply it by 0.453592:
271 pounds * 0.453592 kg/pound = 122.925352 kg
Step 2: Calculate the amount of medicine required
The requirement is 5 mg per 30 kg of weight. Since the patient weighs 122.925352 kg, we can calculate the amount of medicine required using the following formula:
Medicine required (in mg) = (Weight in kg / 30 kg) * 5 mg
Using the patient's weight in kg:
Medicine required (in mg) = (122.925352 kg / 30 kg) * 5 mg
Medicine required (in mg) = 4.097512 kg * 5 mg
Medicine required (in mg) = 20.487558 mg
Therefore, for a patient weighing 271 pounds, approximately 20.5 mg of medicine is required.
