Question

a nurse is preparing to administer acetaminophen 320 mg oral solution to a school-age child. the amount available is acetaminophen oral solution 160 mg/5 ml. how many ml should the nurse administer? (round 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 \(\frac{160\,\text{mg}}{5\,\text{mL}}=\frac{320\,\text{mg}}{x\,\text{mL}}\)

Step2: Cross - multiply

\( 160x = 320\times5 \)

Step3: Solve for \( x \)

\( 160x = 1600 \), so \( x=\frac{1600}{160}=10 \)

Answer:

\( 10 \)
