A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
B
Rationale
The correct answer is B: 2 tablets per dose. To get the total dose of 0.25 mg, the nurse must administer 2 tablets of 0.125 mg each (0.125 mg + 0.125 mg = 0.25 mg). Choosing 1 tablet (A) would result in an insufficient dose. Selecting 3 tablets (C) or 4 tablets (D) would exceed the prescribed dose.
