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 ["1.9"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg. Given that 1 kg = 2.2 lb, we calculate:
165 lb ÷ 2.2 = 75 kg
Step 2 is to calculate the volume of naloxone to be administered. The prescribed dosage is 10 mcg/kg, so we first determine the total dose:
10 mcg/kg × 75 kg = 750 mcg
Next, we convert the available concentration of naloxone from mg/mL to mcg/mL:
0.4 mg/mL × 1000 mcg/mg = 400 mcg/mL
Now, we calculate the required volume by dividing the total dose by the concentration:
750 mcg ÷ 400 mcg/mL = 1.875 mL
Rounding to the nearest tenth, the correct amount to administer is 1.9 mL.
Correct Answer is ["56"]
Explanation
Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.
