Question

Mark is a 2 year old boy just admitted to the hospital with a 102 degree fever. He is to receive acetaminophen (Tylenol) at 5 mg per kg (of body weight) every 4 hours to

reduce the fever. If Mark weighs 27 pounds, calculate the dose in mg that he should receive. Use the factor-label method.

Answer 1

Answer: 61.236 mg of acetaminophen

Explanation: To calculate the dose of acetaminophen (Tylenol) that Mark should receive, we need to convert his weight from pounds to kilograms.

First, you convert Mark's weight from pounds to kilograms using the conversion factor: 1 pound = 0.4536 kilograms.

Mark weighs 27 pounds, so you can calculate his weight in kilograms by multiplying 27 pounds by 0.4536 kilograms per pound:

27 pounds * 0.4536 kilograms/pound = 12.2472 kilograms (rounded to four decimal places)

Now that you have Mark's weight in kilograms, we can calculate the dose of acetaminophen he should receive.

The prescribed dose is 5 mg per kg of body weight. So, you multiply Mark's weight in kilograms by 5 mg/kg:

12.2472 kilograms * 5 mg/kg = 61.236 mg (rounded to three decimal places)

Therefore, Mark should receive a dose of 61.236 mg of acetaminophen
