Question

scenario
mrs. turners orders called for 50 mcg of levothyroxine by mouth daily. the pharmacy stocks the medication in 0.025 mg tablets.
question
how many tablets are needed to administer the ordered dose?

Explanation:

Step1: Convert units to be consistent

We know that \(1\space mg = 1000\space mcg\), so convert \(0.025\space mg\) to \(mcg\).
\(0.025\space mg\times1000 = 25\space mcg\) per tablet.

Step2: Calculate number of tablets

The ordered dose is \(50\space mcg\). To find the number of tablets, divide the ordered dose by the dose per tablet.
\(\text{Number of tablets}=\frac{50\space mcg}{25\space mcg/tablet}= 2\)
