A nurse is preparing to administer digoxin 0.25 mg PO to a client. The amount available is digoxin 0.125 mg tablets. How many tablets should the nurse administer to the client?
(Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To determine how many tablets of digoxin 0.125 mg are needed to administer a total dose of 0.25 mg, divide the desired dose by the dose per tablet:
0.25 mg (desired dose) ÷ 0.125 mg (dose per tablet) = 2 tablets
Therefore, the nurse should administer 2 tablets of digoxin 0.125 mg to the client to achieve a total dose of 0.25 mg.

Correct Answer is D
Explanation
A. Diminished effect from warfarin: This is unlikely because displacement of warfarin from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased anticoagulant effects and toxicity.
B. Diminished effect from paroxetine: This is also unlikely because displacement of paroxetine from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased pharmacological effects and toxicity.
C. Increased effect, and toxicity from paroxetine: If paroxetine displaces warfarin from protein binding sites, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.
D. Increased effect, and toxicity from warfarin: Correct. If warfarin is displaced from protein binding sites by paroxetine, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.
