The client is prescribed digoxin 125 micrograms PO daily. Available is digoxin PO 0.25 milligrams per tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.). Step 1 is convert the prescribed dose from micrograms to milligrams to match the available dosage unit:. 1 milligram = 1000 micrograms. 125 micrograms ÷ 1000 micrograms/milligram = 0.125 milligrams. Step 2 is calculate the number of tablets to administer using the dose available:. 0.125 milligrams ÷ (0.25 milligrams/tablet) = 0.5 tablets. Step 3 is state the final calculated answer at end and round to the nearest tenth:. 0.5 tablets.
