q5. a physician orders 50 mg of an injectable solution. in stock is a vial of the solution with a dose strength of 125 mg/5 ml. what volume of the in - stock solution should be administered?

Answer

Explanation:

Step1: Determine the concentration

The concentration $C$ of the in - stock solution is $\frac{125\ mg}{5\ mL}=25\ mg/mL$.

Step2: Calculate the volume

We know that the mass $m = 50\ mg$, and using the formula $V=\frac{m}{C}$, where $V$ is the volume, $m$ is the mass of the drug, and $C$ is the concentration. Substitute $m = 50\ mg$ and $C = 25\ mg/mL$ into the formula: $V=\frac{50\ mg}{25\ mg/mL}=2\ mL$.

Answer:

$2\ mL$
