What does the acronym SLUDGEM stand for in nerve agent exposure symptoms?

• A. Salivation, Lacrimation, Urination, Defecation, Gastric upset, Emesis, Miosis
• B. Salivation, Lacrimation, Urination, Defecation
• C. Salivation, Lacrimation, Urination
• D. Defecation, Emesis, Gastric upset, Miosis

Answer: (A)

When a nerve agent inhibits acetylcholinesterase, acetylcholine builds up and overactivates muscarinic receptors, producing a recognizable cluster of symptoms. This set is captured by SLUDGEM: Salivation, Lacrimation, Urination, Defecation, Gastric upset, Emesis, and Miosis. Each part reflects excessive parasympathetic activity—too much saliva, tearing, urge to urinate, bowel movements, stomach cramps or upset, vomiting, and pinpoint pupils. This complete pattern helps responders identify a cholinergic exposure quickly. Other options miss one or more of these signs, so they don’t represent the full muscarinic symptom profile. If you see drooling, tearing, urgent urination, diarrhea or cramps, vomiting, and constricted pupils after a suspected chemical exposure, SLUDGEM is the mnemonic to recall.
