Help dosage problem?

A physician prescribed accutane 2mg/kg/day po twice daily for a 110pd teenager with acne. Accutane is available 50 mg tablets. How many tablets should the physician instruct the teenager to take each dose?

i know you convert 110 to 50kg. So do I multiply that by 2mg and get 100mg? What about the twice daily?

    110/2.2= 50kg*2mg=100mg/2=50mg/50mg= 1 tab is that correct?

    A physician ordered ampicillin gram 1 q12 hours for a 110 lb teenager who acquired an infection when he stepped on a shell at the beach.. Ampicillin is available in 500 mg capsules. What will you administer per day?

    110/2.2=50 kg*1000mg? I'm stuck

    I don't think you have to worry about the weight conversion to kg as it isn't mentioned in the problem. How many mg in 1 gram. Then you should now how many capsules you need.

    You can check if there is a safe dose range in your drug book

    What is the amount per dose?

    How many capsules per dose?

    How many doses per day?

    How many capsules per day?

    It's NOT 1g/kg. Generally after age 12 most drugs are not weight based.

    Look at what the question is asking. That is why I wrote what I did. If you have more just ask but show where you are stuck so we can guide you to finding the answer yourself
