Tylenol 3 has 16 mg of Codeine per 11 ml of liquid. A safe dose of Codeine is 4.8 mg/Kg/Day.
A patient who weighs 215 pounds needs a Tylenol 3 prescription. There are 2.2 pounds for every 1 kilogram. How many kilograms is this person's mass?
How many milligrams of Codeine can this patient have per day?
How many milliliters should the patient be prescribed every 6 hours of Tylenol 3.
To answer these questions, we need to follow several steps. Let's break it down step by step.
1. Convert the patient's weight from pounds to kilograms:
We need to divide the weight in pounds by the conversion factor of 2.2 pounds per kilogram.
215 pounds / 2.2 pounds per kilogram = 97.73 kilograms
Therefore, the patient weighs approximately 97.73 kilograms.
2. Find the safe dose of Codeine per day for the patient:
We'll multiply the patient's weight in kilograms by the safe dose of Codeine, which is 4.8 mg/kg/day.
97.73 kilograms * 4.8 mg/kg/day = 469.54 mg/day
Therefore, the patient can have up to 469.54 milligrams of Codeine per day.
3. Determine the amount of Tylenol 3 the patient should be prescribed every 6 hours:
Let's start by calculating the total dose of Codeine the patient is allowed in a day. We'll divide the total daily dose (469.54 mg) by 24 to get the amount of Codeine per hour.
469.54 mg/day ÷ 24 hours = 19.56 mg/hour
Since the prescription is taken every 6 hours, we'll divide the Codeine per hour by 6 to find the amount of Codeine per 6 hours.
19.56 mg/hour ÷ 6 = 3.26 mg/6 hours
Now, we can use the information provided that Tylenol 3 has 16 mg of Codeine per 11 ml of liquid. We'll convert the dose from milligrams to milliliters.
(3.26 mg/6 hours) ÷ (16 mg/11 ml) = (3.26 mg × 11 ml) ÷ (6 hours × 16 mg) = 5.72 ml
Therefore, the patient should be prescribed approximately 5.72 milliliters of Tylenol 3 every 6 hours.
