Question

the physician assistant at a health care center is reading the drug label for levothroid, and notices that it says, levothroid 25 mcg per tablet. the doctor has prescribed levothroid 0.1 mg orally per day. the physician assistant will administer □ tablet(s). (simplify your answer.)

Explanation:

Step1: Convert units

Since \(1\ mg = 1000\ mcg\), then \(0.1\ mg=0.1\times1000 = 100\ mcg\).

Step2: Calculate the number of tablets

Let \(n\) be the number of tablets. We know that each tablet has \(25\ mcg\) of the drug. Using the formula \(n=\frac{\text{Total dose in mcg}}{\text{Dose per tablet in mcg}}\), so \(n = \frac{100}{25}\).

Answer:

\(4\)
