How many digoxin tablets will the nurse administer if the patient requires 0.5 mg and the tablets are each 0.25 mg?

To determine how many digoxin tablets to administer, you first need to calculate the total number of tablets required to reach the prescribed dosage of 0.5 mg. Each tablet contains 0.25 mg of digoxin.

To find the number of tablets needed, divide the total required dose (0.5 mg) by the amount in each tablet (0.25 mg):

0.5 mg ÷ 0.25 mg/tablet = 2 tablets.

This calculation shows that the patient requires 2 tablets to meet the prescribed dosage of 0.5 mg. Therefore, administering 2 tablets is correct as it accurately delivers the intended dose.
