Question

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.) tablets

Explanation:

Step1: Calculate the number of tablets

Use the formula: $\text{Number of tablets}=\frac{\text{Dose ordered}}{\text{Dose available}}$
Here, the dose ordered is $0.25$ mg and the dose available is $0.125$ mg per tablet.
So, $\text{Number of tablets}=\frac{0.25}{0.125}$

Step2: Simplify the fraction

$\frac{0.25}{0.125}=\frac{250}{125}$ (multiply numerator and denominator by 1000 to remove decimals)
$\frac{250}{125} = 2$

Answer:
