a pharmacy technician dilutes a 1 g vial of cefazolin (ancef) to 100 mg/ml. which of the following is the amount of solution the technician should use to compound a 500 mg dose? 2.5 ml 10 ml 0.5 ml 5 ml

Answer

Explanation:

Step1: Identify the concentration - amount relationship

The concentration is $100$ mg/mL, and we want a $500$ mg dose. Use the formula $V=\frac{m}{C}$, where $V$ is volume, $m$ is mass, and $C$ is concentration.

Step2: Substitute values into the formula

$V=\frac{500\text{ mg}}{100\text{ mg/mL}}$ $V = 5$ mL

Answer:

D. 5 mL
