A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/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.)

Convert the Available Dose from milligrams (mg) to micrograms (mcg) Available Dose = 0.25 mg/tablet Conversion factor: 1 mg = 1,000 mcg Available Dose (mcg/tablet) = 0.25 mg/tablet x 1,000 mcg/mg = 250 mcg/tablet Calculate the Number of Tablets Ordered Dose (D) = 125 mcg Available Dose (H) = 250 mcg Quantity (Q) = 1 tablet Tablets = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q) = (125 mcg / 250 mcg) x 1 tablet = 0.5 x 1 tablet = 0.5 tablet
