Question

using the method of your choice
proportion (linear)
d : a :: h : v
cross - multiplication
d/a = h/v
formula
a = d x v/h
order: synthroid 0.1 mg
available: synthroid 50 mcg tablets
how many tablets will the nurse administer?

Explanation:

Step1: Convert units

Since \(1\ mg = 1000\ mcg\), then \(D = 0.1\ mg=0.1\times1000 = 100\ mcg\), \(H = 50\ mcg\), \(V = 1\ tablet\)

Step2: Apply the formula \(A=\frac{D\times V}{H}\)

Substitute the values into the formula: \(A=\frac{100\times1}{50}\)

Step3: Calculate the value of \(A\)

\(A=\frac{100}{50}=2\)

Answer:

\(2\) tablets
