A client is taking pyridostigmine for muscle weakness associated with myasthenia gravis. The nurse educates the client on which possible cholinergic side effects associated with this medication? (Select all that apply)

The correct choices for cholinergic side effects associated with pyridostigmine are excessive sweating (C), bradycardia (D), and excessive lacrimation (E). Pyridostigmine is a cholinesterase inhibitor that increases acetylcholine levels, leading to increased parasympathetic activity. Excessive sweating occurs due to overstimulation of sweat glands by acetylcholine. Bradycardia results from enhanced vagal tone on the heart, slowing the heart rate. Excessive lacrimation is due to increased stimulation of the lacrimal glands. Tachycardia (A) is not a typical cholinergic side effect but rather an anticholinergic effect. Dry mouth (B) is a common anticholinergic side effect, not cholinergic.
