When administering digoxin 1.5mg PO from available tablets of 0.5mg, how many tablets should the nurse administer?

To determine the correct number of tablets to administer when giving a total dose of 1.5mg of digoxin using tablets available in 0.5mg each, you can perform a straightforward calculation.

First, you would divide the total dose required (1.5mg) by the strength of each tablet (0.5mg). The calculation would look like this:

1.5mg ÷ 0.5mg/tablet = 3 tablets

This shows that the nurse should administer a total of three 0.5mg tablets to achieve the required dosage of 1.5mg. Therefore, three tablets will provide the correct amount of medication needed for the patient. Proper dosage calculations like this are crucial in ensuring safe and effective medication administration in clinical practice.
