... I was taught to round to nearest tenth which would be 6.3ml if dose volume greater than 1 ml. but does this apply if max dose is calculated to the hundredth of an ml?

Regardless of how many decimal places you use when you calculate the volume, the limiting factor is going to be the graduation marks on the syringe you're using. All 3 - 10/12 mL oral syringes am familiar with are graduated in 0.1 mL increments. While you could could estimate a volume to 0.05 mL, anything other than this would be difficult.

... Should 1.3636 ml be rounded to 1.4 ml then divide or leave it and round the final calculation which I came up with 0.68ml per injection

I complete all calculations, and then round the final answer.

Best wishes.

How it worked at my school, we didn't really consider the syringe that would be used unless it was given in the question. We just calculated the dosage, and then we rounded according to the rounding rules we were given. But, I can't ever think of an instance in school where they had us calculate to the hundredth of a mL. There might of been one, I just don't remember .? Is there a specific reason you're asking since you were told to round to nearest tenth?

Like chare said, when I was in school, I completed all my calculations and then I rounded the final answer. However, you could ask your instructor what he/she prefers - you rounding at the end or you rounding as you go.
