    When doing pediatric calculations I've been told to round to the nearest hundredth.

    I am confused because when drawing up medication it's almost impossible to go to the hundredth.
    So if the dose is 3.87 tsp
    Or 210.82 mg
    Do you administer 4 tsp or 211 mg?

    Thanks!

    What I was taught is if teh dose is less than 1 round to the nearest hundredth. Greater than one round to the nearest tenth.

    Doses should never be ordered in teaspoons. How many mL are in one teaspoon? 5, right? So if you have 3.87 tsp, that's 19.35 mL (Good luck getting a child to take that volume of medication) which you CAN measure with a syringe.

    If the mg/kg calculation came out to 210.82 mg, it should be rounded to 211 mg. This should be done when the physician is ordering the medication.

    thank you! The amounts were answers from a pharmacology calculation quiz. I was just wondering how those amounts would be administered. Converting tsp to mL makes sense. Thanks!
