A physician orders Tylenol 3 (codeine/APAP) 30 mg by mouth every 4-6 hours as needed for pain. The nurse has Tylenol 3 available as 30/300 mg tablets. How many tablets should the nurse administer to the patient?
0.1 tablets
0.5 tablets
1 tablet
3 tablets
The Correct Answer is C
The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.
The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..
It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.

Correct Answer is C
Explanation
To calculate the rate per hour, divide the amount of magnesium sulfate to be administered by the concentration of magnesium sulfate in the IV bag:
6 grams ÷ 40 grams = 0.15
Then, multiply the result by the volume of the IV bag, which is usually 1000 mL: 0.15 x 1000 mL = 150 mL
This is the amount of fluid that contains 6 grams of magnesium sulfate. To administer this amount over 30 minutes, multiply by 2 to get the rate per hour:
150 mL x 2 = 300 mL/hr.
