Question 1 of 5

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.)

Your Answer:

Correct Answer: B

Rationale:
To calculate the number of tablets needed, divide the prescribed dose by the strength of each tablet. In this case, 0.25 mg ÷ 0.125 mg = 2 tablets. Rounding to the nearest whole number, the nurse should administer 2 tablets per dose. This ensures the client receives the correct dosage as prescribed.

Choice A is incorrect because administering only 1 tablet would provide half of the prescribed dosage.
Choice C is incorrect as administering 3 tablets would exceed the prescribed amount.
Choice D is incorrect as administering 4 tablets would also exceed the prescribed dosage.
Therefore, the correct answer is B.
