Question

what type of poisoning should you suspect when your patient presents with a slow pulse, excessive salivation and sweating, nausea, vomiting, difficulty breathing, and constricted pupils?

aspirin.
insecticide.
antihistamine.
acetaminophen.

Explanation:

Analyze the clinical presentation

Using the Organophosphate Poisoning knowledge point

• The patient presents with a slow pulse (bradycardia), excessive salivation, sweating (diaphoresis), nausea, vomiting, difficulty breathing (bronchospasm/bronchorrhea), and constricted pupils (miosis).
• These signs and symptoms represent a classic cholinergic toxidrome, commonly remembered by the mnemonic SLUDGEM (Salivation, Lacrimation, Urination, Defecation, Gastrointestinal upset, Emesis, Miosis).

Match toxidrome to the options

Using the Organophosphate Poisoning knowledge point

• Organophosphates and carbamates, which are commonly found in insecticides, inhibit the acetylcholinesterase enzyme, leading to an accumulation of acetylcholine and overstimulation of the parasympathetic nervous system.
• Aspirin (salicylate) overdose typically presents with tachypnea, tinnitus, hyperthermia, and metabolic acidosis.
• Antihistamine overdose presents with anticholinergic symptoms (dry mouth, rapid heart rate, dilated pupils, hot/dry skin).
• Acetaminophen overdose primarily causes delayed hepatotoxicity without these acute cholinergic signs.
• Therefore, insecticide poisoning is the correct clinical suspicion.

Answer:

• (A) Aspirin.
• (B) Insecticide. (Correct answer)
• (C) Antihistamine.
• (D) Acetaminophen.
