Multiple Choice

Which symptom is part of botulism SxS?

Botulism toxin blocks the release of acetylcholine at neuromuscular junctions, causing a descending, symmetric weakness. Early cranial nerve involvement leads to eye-related symptoms, such as ptosis (drooping eyelids) and vision changes, which is a classic sign of botulism. The other options don’t fit this picture: a rash isn’t a feature of botulism, tremors imply different neurological patterns, and hypertension isn’t typical for botulism ( autonomic effects can occur, but high blood pressure is not a hallmark). So drooping eyelids reflect the cranial nerve weakness caused by botulism.
