83. If a drug dose is 50 mcg how many doses are contained in 0.01 g?

Answer: C

Explanation:

There are 200 doses contained in 0.01 g.

To determine the number of doses in 0.01 g when each dose is 50 mcg, we first convert 0.01 g to mcg. Since 1 g is equal to 1,000,000 mcg, 0.01 g is equal to 10,000 mcg. Dividing 10,000 mcg by 50 mcg gives us 200 doses.

A) 2

Option A is incorrect because it significantly underestimates the number of doses. If there were only 2 doses, the total amount would equal 100 mcg (2 doses x 50 mcg), which is much less than 10,000 mcg.

B) 20

Option B is also incorrect as it suggests there are only 20 doses. This would total 1,000 mcg (20 doses x 50 mcg), which is still far below the 10,000 mcg available in 0.01 g.

C) 200

Option C is correct because it accurately calculates the number of doses. With 0.01 g equating to 10,000 mcg, dividing this amount by the 50 mcg per dose results in exactly 200 doses (10,000 mcg ÷ 50 mcg = 200).

D) 2000

Option D is incorrect as it overestimates the number of doses. If there were 2000 doses, that would imply a total of 100,000 mcg (2000 doses x 50 mcg), which exceeds the available 10,000 mcg from 0.01 g.

Conclusion

Option C is definitively correct as it properly calculates the total number of doses based on the given drug dosage and total amount available. The other options fail to align with the mathematical conversion from grams to micrograms or miscalculate the resulting doses. Thus, only Option C accurately reflects the relationship between the total drug amount and individual dose size.
