A nurse is preparing to administer acetaminophen 300 mg PO every 4 hr PRN headache.
Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.
Use a leading zero if it applies.
Do not use a trailing zero.). mL. .
The Correct Answer is ["9.4"]
Step 1 is to calculate the dose to be administered which is 300 mg. Step 2 is to calculate the concentration of the available medication which is 160 mg/5 mL. Step 3 is to calculate the volume to be administered as (300 mg ÷ (160 mg/5mL)) = 9.375 mL.
So, the correct answer is, after analyzing all steps, the nurse should administer 9.4 mL per dose (rounded to the nearest tenth).

Correct Answer is ["2.1"]
Explanation
First, we need to calculate the total daily dose of tobramycin for the client. The total daily dose is calculated as follows:
Total daily dose = Dose per kg per day x Weight Total daily dose = 3 mg/kg/day x 85 kg Total daily dose = 255 mg/day
Since the total daily dose is divided into three doses, each dose will be:
Each dose = Total daily dose / Number of doses Each dose = 255 mg / 3 Each dose = 85 mg
Now, we need to convert this dose into mL. We know that we have tobramycin 40 mg/mL, so:
Volume to administer = Each dose / Concentration Volume to administer = 85 mg / 40 mg/mL Volume to administer = 2.125 mL
Rounding this to the nearest tenth, we get 2.1 mL.
