a nurse is preparing to administer potassium chloride 15 meq po every 12 hr. available is potassium chloride liquid 20 meq/15 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. The proportion is $\frac{15\ mEq}{x\ mL}=\frac{20\ mEq}{15\ mL}$.

Step2: Cross - multiply

$20x = 15\times15$.

Step3: Solve for $x$

$x=\frac{15\times15}{20}=\frac{225}{20} = 11.25$.

Step4: Round to nearest whole number

Rounding $11.25$ to the nearest whole number gives $11$.

Answer:

$11$
