Question

question 25 of 25
a nurse is preparing to administer fluoxetine 35 mg po daily. available is fluoxetine solution 20 mg/5 ml. how many ml should the nurse administer daily? (round the answer to the nearest tenth. 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 to be administered. We know that the concentration is 20 mg per 5 mL and the required dose is 35 mg. So the proportion is $\frac{20\ mg}{5\ mL}=\frac{35\ mg}{x\ mL}$.

Step2: Cross - multiply

$20x = 35\times5$.

Step3: Solve for $x$

$20x=175$, then $x=\frac{175}{20}=8.75$.

Step4: Round to nearest tenth

Rounding 8.75 to the nearest tenth gives 8.8.

Answer:

8.8
