How many tablets of acetaminophen, available at 325mg each, should be administered for a total dose of 650 mg?

To determine the correct number of tablets of acetaminophen to administer for a total dose of 650 mg, you start by noting the strength of each tablet, which is 325 mg.

You can find the number of tablets required by dividing the total desired dose by the strength of one tablet. In this case, dividing 650 mg by 325 mg per tablet results in 2 tablets.

This calculation illustrates that you need two tablets of 325 mg each to achieve a total dosage of 650 mg, effectively doubling the single tablet's dosage. Thus, the rationale for administering 2 tablets stems from the straightforward mathematical relationship between the total dosage required and the dosage per tablet.
