Question: 1 / 400

Which symptoms are expected in a patient with organophosphate poisoning?

A) Flushed skin, blurred vision, and tachycardia

B) Excessive salivation, bradycardia, and vomiting

In organophosphate poisoning, the symptoms arise due to the inhibition of acetylcholinesterase, leading to an excess of acetylcholine at the neuromuscular junctions and other sites in the body. The expected symptoms include excessive salivation, which is a classic sign of cholinergic toxicity due to overstimulation of salivary glands. Bradycardia, or a slower than normal heart rate, also occurs as a result of increased parasympathetic activity. Vomiting can be a secondary response due to the overstimulation of the gastrointestinal tract.

These symptoms reflect the cholinergic crisis that characterizes organophosphate toxicity, where the body is overwhelmed by the effects of excessive acetylcholine. It's important to understand that the other answer choices describe symptoms that do not align with the toxicological profile of organophosphate poisoning, which primarily shows prominent cholinergic signs.
