What are the common symptoms of organophosphate poisoning?

Organophosphate poisoning occurs when individuals are exposed to organophosphate compounds, which are commonly found in various pesticides. The correct choice highlighting the symptoms of this type of poisoning includes constricted pupils, dizziness, and vomiting.

Constricted pupils, or miosis, is a specific and telling sign of organophosphate poisoning due to the inhibition of acetylcholinesterase, leading to an accumulation of acetylcholine at synapses. This accumulation causes various cholinergic symptoms, including changes in pupil size. Dizziness can occur as a result of both the physiological effects of poisoning and the toxicological impact it has on the central nervous system. Vomiting may arise due to the body’s attempt to expel the toxin and is also a common autonomic response to such toxic exposures.

Other listed symptoms such as rash, headache, fatigue, fever, cough, or generalized fatigue are typically associated with various other conditions or types of chemical exposures and are not specifically indicative of organophosphate poisoning. Understanding the precise symptoms associated with such poisoning is crucial for prompt recognition and treatment, making option A the correct choice.
