The purpose of routine cholinesterase monitoring is to help physicians recognize what?

• A. Excessive exposure to organophosphate and carbamate insecticides
• B. Any pesticide exposure
• C. Skin irritation from pesticides
• D. All pesticide spills

Answer: (A)

Cholinesterase monitoring is used to detect excessive exposure to pesticides that inhibit cholinesterase—principally organophosphate and carbamate insecticides. These chemicals block acetylcholinesterase, leading to a buildup of acetylcholine and a cholinergic crisis. By comparing a worker’s current cholinesterase activity to a baseline, physicians can identify meaningful decreases that signal harmful exposure even before severe symptoms appear. This test is specific to those types of pesticides and isn’t a measure of any pesticide exposure, skin irritation, or spill events, which is why the other options aren’t correct.
