Final answer:
In a patient taking high doses of acetaminophen over a prolonged period, it is important to monitor liver function and kidney function to assess any potential damage. Prothrombin time does not need monitoring in this case.
Step-by-step explanation:
In a patient taking high doses of acetaminophen over a prolonged period, it is important to monitor liver function due to the potential risk of liver damage. Acetaminophen is metabolized in the liver, and high doses can put strain on the liver, increasing the risk of toxicity. Regular monitoring of liver enzymes, such as alanine transaminase (ALT) and aspartate transaminase (AST), can help assess liver health.
Another important parameter to monitor is kidney function. Acetaminophen can cause kidney damage, especially if taken in high doses or for extended periods. Tests such as blood urea nitrogen (BUN) and serum creatinine can help evaluate kidney function.
Monitoring prothrombin time is not necessary in a patient taking high doses of acetaminophen, as it does not directly affect blood clotting.
