a nurse is preparing to administer acetaminophen 325 mg po every 6 hr. available is acetaminophen oral suspension 160 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. The proportion is $\frac{160\ mg}{5\ mL}=\frac{325\ mg}{x\ mL}$.

Step2: Cross - multiply

$160x = 325\times5$.

Step3: Solve for $x$

$x=\frac{325\times5}{160}=\frac{1625}{160}=10.15625$.

Step4: Round to nearest whole number

Rounding $10.15625$ to the nearest whole number gives $10$.

Answer:

$10$
