A common cause of liver toxicity is:
Select one:
daily hydrochlorothiazide administration for hypertension
long term smoking of a pack of cigarettes per day
taking extra strength acetaminophen at doses of 4500 mg per day 1
regular consumption of a high fiber diet throughout life
The Correct Answer is C
A. Hydrochlorothiazide is a diuretic used to treat hypertension; while it can have side effects, liver toxicity is not a common one.
B. Long-term smoking affects the lungs and cardiovascular system more prominently than the liver.
C. Acetaminophen (especially at or above 4,000 mg/day) is a leading cause of liver toxicity, particularly in overdose or prolonged high-dose use. A dose of 4,500 mg/day exceeds the recommended maximum and increases the risk for liver damage.
D. A high-fiber diet is generally beneficial and not associated with liver toxicity.

C. Financial concerns may influence a patient’s decisions, but they do not legally invalidate informed consent as long as the patient remains mentally competent and unmedicated.
