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 B

B. In acute liver failure and encephalopathy, protein may be restricted to minimize ammonia production, and sodium may be restricted to manage fluid retention and prevent further complications.

Correct Answer is C
Explanation
A. Excessive fluid losses may lead to dehydration, but this is not typically a primary concern for patients with pulmonary alterations unless there is significant vomiting, diarrhea, or blood loss.
B. Hemodilution is not a common concern in patients with pulmonary alterations. Hypernatremia typically occurs with fluid loss or inadequate fluid intake, but it is not a direct concern related to pulmonary issues.
C. Fluid volume excess can lead to right-sided heart failure in patients with pulmonary alterations. If fluid accumulates, it can worsen pulmonary symptoms and increase the workload on the heart, potentially leading to right-sided heart failure.
D. Fluid retention with tachypnea is not typically a direct cause of fluid retention. While tachypnea is associated with respiratory distress, fluid retention is more closely linked to heart failure or kidney dysfunction.
