Question

a nurse is preparing to administer digoxin 250 mcg po daily. 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.)

Explanation:

Step1: Convert units

First, convert 0.125 mg to mcg. Since 1 mg = 1000 mcg, then 0.125 mg = 0.125×1000 = 125 mcg.

Step2: Calculate number of tablets

Use the formula: Number of tablets = $\frac{\text{Dose ordered}}{\text{Dose per tablet}}$. Here, the dose ordered is 250 mcg and the dose per tablet is 125 mcg. So, $\frac{250}{125}=2$.
