A nurse is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 0.25 mg = 1 tablet / 0.125 mg
Cross-multiplying:
0.125x = 0.25
Solving for x:
x = 0.25 / 0.125
x = 2
Therefore, the nurse should administer 2 tablets of digoxin daily.

Correct Answer is A
Explanation
When transcribing a dosage of two-tenths of a milligram, it's important to use the leading zero to clearly indicate the decimal point and prevent misinterpretation.
0.20 mg explicitly shows that the dose is two-tenths of a milligram.
2.0 mg could be misinterpreted as two milligrams.
2 mg without the decimal point could also lead to confusion.
Therefore, using 0.20 mg is the most accurate and unambiguous way to represent the dosage of two-tenths of a milligram.
Correct Answer is ["2"]
Explanation
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 100 mcg = 1 tablet / 50 mcg
Cross-multiplying:
50x = 100
Solving for x:
x = 100 / 50
x = 2
Therefore, the nurse should administer 2 tablets of levothyroxine daily.
