question 20 of 25
a nurse is preparing to administer magnesium gluconate 270 mg po every 6 hr. available is magnesium gluconate liquid 54 mg/5 ml. how many ml should the nurse administer per dose? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Set up proportion

Let $x$ be the volume in mL. We have the proportion $\frac{54\ mg}{5\ mL}=\frac{270\ mg}{x\ mL}$.

Step2: Cross - multiply

$54x = 270\times5$.

Step3: Solve for $x$

$x=\frac{270\times5}{54}$.
$x = 25$.

Answer:

25
