The nurse is caring for a patient with liver dysfunction. What is the maximum dose of acetaminophen the patient should receive in 24 hours?
2g
500 mg
4g
1g
The Correct Answer is A
A. 2g is correct because for patients with liver dysfunction, the maximum recommended dose of acetaminophen is reduced to 2 grams per day to prevent hepatotoxicity.
B. 500 mg is incorrect because while lower doses may be given at a time, the total daily limit for liver-compromised patients is higher than 500 mg.
C. 4g is incorrect as this is the maximum dose for healthy adults with normal liver function, but it is too high for those with liver disease.
D. 1g is incorrect because while it is a single-dose limit, the daily maximum for patients with liver dysfunction is 2g, not 1g.

Correct Answer is ["21.6"]
Explanation
Convert pounds to kilograms:
- 198 lbs / 2.2 lbs/kg = 90 kg
Calculate the medication dose in mcg/min:
- 90 kg 4 mcg/kg/min = 360 mcg/min
Convert mcg/min to mg/hr:
- 360 mcg/min 60 min/hr = 21600 mcg/hr
- 21600 mcg/hr / 1000 mcg/mg = 21.6 mg/hr
Determine the medication concentration:
- 250 mg / 250 mL = 1 mg/mL
Calculate the infusion rate in mL/hr:
- 21.6 mg/hr / 1 mg/mL = 21.6 mL/hr
