Which of the following is a remembered adverse effect of anticholinergic drugs like atropine?

Explanation:
Anticholinergic drugs block muscarinic receptors, dampening parasympathetic activity. In the gastrointestinal tract, acetylcholine normally promotes smooth muscle contraction and peristalsis; when this signaling is blocked, gut motility decreases, leading to slower transit and constipation. This slowed GI movement is the remembered adverse effect of atropine-like meds. Increased GI motility or diarrhea would require cholinergic stimulation, which these drugs oppose, and muscle tremor is not a typical hallmark adverse effect.
