Correct Answer is ["0.5"]
Explanation
To calculate the number of tablets the nurse should dispense to the client, we need to convert the prescribed dose of digoxin from milligrams (mg) to micrograms (mcg), as the tablets are labeled in milligrams.
1 mg = 1000 mcg
125 mcg = (125 mcg) / (1000 mcg/mg) = 0.125 mg
Now, we can determine the number of tablets needed to achieve this dose:
0.125 mg ÷ 0.25 mg/tablet = 0.5 tablets
