The physician ordered Lanoxin tabs, 0.125 mg. Available are Lanoxin tabs, 0.25 mg.

How many tablets will you give?

1 answer

To find out how many tablets of Lanoxin (0.25 mg) to give for a dose of 0.125 mg, you can use the following calculation:

  1. Determine the dose required: 0.125 mg
  2. Determine the dose available: 0.25 mg

Next, you can find out how many 0.25 mg tablets are needed to achieve a 0.125 mg dose:

\[ \text{Number of tablets} = \frac{\text{Dose required}}{\text{Dose available}} = \frac{0.125 \text{ mg}}{0.25 \text{ mg}} = 0.5 \]

So, you would give half of a 0.25 mg tablet, which is equal to 0.125 mg.
