please solve the following medication administration dose calculation problem:
order: cephalexin 375 mg via g - tube, every 12 hours
supply: the label of the bottle reads cephalexin (keflex) oral suspension 250 mg/5 ml
how many mls will you give? ______

Explanation:

Step1: Set up proportion

Let $x$ be the volume in ml. We have the proportion $\frac{250\ mg}{5\ ml}=\frac{375\ mg}{x\ ml}$.

Step2: Cross - multiply

$250x = 375\times5$.

Step3: Solve for $x$

$x=\frac{375\times5}{250}=\frac{1875}{250} = 7.5$.

Answer:

$7.5$
