The physician orders Lanoxin 0.05 mg IV this morning. Select the dosage strength from the Lanoxin drug label that requires no additional conversion factor to solve for the ordered dose. \( \frac{100 \mathrm{mcg}}{0.1 \mathrm{mg}} \) \( \frac{0.1 \mathrm{mg}}{100 \mathrm{~mL}} \) \( \frac{1 \mathrm{~mL}}{0.1 \mathrm{mg}} \)

Did you know that the active ingredient in Lanoxin, digoxin, has been used for over 200 years to treat heart conditions? Originally derived from the foxglove plant, it was first documented in the 18th century by the famous physician William Withering, who discovered its beneficial effects on heart failure. When it comes to real-world applications, knowing how to interpret drug labels is essential for safe medication administration. In this case, the option \( \frac{1 \mathrm{~mL}}{0.1 \mathrm{mg}} \) is the most straightforward for administering Lanoxin since it directly relates the volume to the medication's strength without requiring any further conversion. This means if you need 0.05 mg, you would simply take 0.5 mL of the solution!
