Conjugated estrogens tablets (PREMARIN) are available in strengths of 0.3 mg, 0.45 mg, 0.625 mg, 0.9 mg and 1.25 mg. If patient "A" took one tablet daily of the lowest dose and patient ‘‘B’’ took one tablet daily of the highest dose, what is the difference in the total quantities taken between patients ‘‘A’’ and ‘‘B’’ over a period of 30 days (a) 2.85 mg (b) 2850mg (c) 2.85 cg (d) 2.85dg

(c) 2.85 cg

Explanation:

Patient A:  

- Lowest dose >> 0.3 mg x 30 days = 9 mg

Patient B:  

- Highest dose >> 1.25 mg x 30days  = 37.5 mg

Comparison of dose between patients  = 37.5 mg - 9 mg = 28.5 mg >>>  1 centigram is equivalent to ten (10) milligrams (mg), thereby the correct answer is (c) 2.85 cg
