A physician requests 600 mg of a medication, which is weighed by a pharmacy technician. Upon double-checking the amount by using a more sensitive balance, he finds the amount to actually be 575 mg. The difference is 25 mg. What is the percentage of error?
2%
3%
4%
5%
4%
Rationale: The percentage of error is 4%. If a certain percentage of error is not to be exceeded, and the maximum potential error of the measuring instrument is known, you can calculate the smallest quantity that can be measured within the desired accuracy: 100 x maximum potential error / Permissible percentage of error. This will equal the smallest quantity. Therefore, 100 x 25 / 600 = 4%.
