Question

solve the following parenteral dosage problem.
the physician orders heparin 8,000 units. the heparin label reads 20,000 units per milliliter.
how many milliliters should be given?

milliliter(s)
(simplify your answer. type an integer or decimal rounded to the nearest tenth as needed.)

Explanation:

Step1: Set up the proportion

Let \(x\) be the volume in milliliters. The proportion is \(\frac{8000\ units}{x\ mL}=\frac{20000\ units}{1\ mL}\).

Step2: Solve for \(x\)

Cross - multiply: \(20000x = 8000\times1\). Then \(x=\frac{8000}{20000}\).

Step3: Simplify the fraction

\(x = 0.4\)

Answer:

\(0.4\)
