Question

( 56.You are to prepare a dose of "/so gr. You have available tablets of 650 mcg, 300 mcg, and 150 mcg. What is the least number of tablets you can use (and which tablets) to make up the dose?

Answer 1

56) We know that, 1 gr = 0.0647989 g

Given, dose = 1/50 gr = 0.02 gr = (0.02 x 0.0647989) g = 0.001295978 g = 1295.978 mcg (As 1 g = 1,000,000 mcg)

Least number of tablets will be those that have higher amount. So, 650 mcg tablet will be required least number.

So, required number of 650 mcg tablets = 1295.978 / 650 = 1.99 $\approx$ 2

Thus, at least 2 tablets of 650 mcg require to prepare the dose.
