Among the following, which symptom is part of the DUMBELS acronym and relates to excretory function?

Explanation:
DUMBELS describes the cholinergic toxidrome seen with organophosphate or nerve agent exposure. The symptom that relates to excretory function is Urination—the “U” in the acronym. Excess acetylcholine stimulates muscarinic receptors, increasing smooth muscle activity and secretions, including bladder contractions that lead to more frequent urination. The other items map to different parts of the response (diarrhea, miosis, bronchorrhea/bronchospasm, emesis, lacrimation, salivation), not excretory function. So urination best fits the excretory aspect of this mnemonic.
