Weight - 20 pounds 6 ounces
Ordered dose - 1.5mg per kilogram per day
recommended dosage from drug label - 3mg every 8 hours.
1.What is the individual dose?
to find the individual dose i'll first convert pounds to kg which is 9.26 kg. I will then multiply 1.5 x 9.26 = 13.89 mg. So the individual dose is 13.89 mg.
2.What is the daily dose?
to find the daily dose I would multiply 13.89 x 3 = 41.67 mg.
However,the back of the answer states that individual dose is 4.63mg and daily dose is 13.89 mg.
Why is that?
It seems there may be an error in the calculations provided in the question. Let's go through the calculations again to find the correct answers.
1. Individual Dose:
To convert weight from pounds to kilograms, we need to remember that 1 pound is approximately equal to 0.4536 kilograms. So, 20 pounds 6 ounces is approximately 20.375 pounds.
20.375 pounds * 0.4536 kg/pound = 9.25 kg (approximately)
Now, to find the individual dose, we multiply the weight in kilograms by the recommended dose per kilogram:
9.25 kg * 1.5 mg/kg = 13.875 mg
Therefore, the correct individual dose is approximately 13.875 mg (approximately equivalent to 13.89 mg).
2. Daily Dose:
The recommended dosage from the drug label is 3 mg every 8 hours. To find the daily dose, we first need to determine how many times this dosage is taken in a day.
24 hours / 8 hours = 3 times per day
Now, we multiply the dosage per administration by the number of times per day:
3 mg/dose * 3 doses/day = 9 mg/day
Therefore, the correct daily dose is 9 mg.
To summarize the correct answers:
Individual dose: 13.89 mg (approximately)
Daily dose: 9 mg
The initial calculations provided in the question were incorrect, resulting in the incorrect answers stated on the answer sheet.
