1. an agent which affects blood pressure by increasing the flow of urine and thus reducing the volume of fluid in the body is called:

a: emetic b: diuretic
c: depressant d: cathartic

Explanation:

Step1: Set up proportion

Let \(x\) be the volume (in cc) to draw up. We know that the concentration is \(80\) mg per cc. So, \(\frac{80\ \text{mg}}{1\ \text{cc}}=\frac{20\ \text{mg}}{x\ \text{cc}}\).

Step2: Solve for \(x\)

Cross - multiply: \(80x = 20\times1\). Then \(x=\frac{20}{80}\). Simplify \(\frac{20}{80}=\frac{1}{4}=0.25\).

Answer:

C. \(0.25\) cc
