Question 1 of 31

Your depressed patient who is taking a tricyclic antidepressant is advised of possible anticholinergic side effects. Which of the following is NOT an anticholinergic side effect?

Rationale:
Muscle rigidity is NOT an anticholinergic side effect. Anticholinergic effects primarily include symptoms related to decreased acetylcholine activity, such as dry mouth, blurred vision, and urinary difficulties, while rigidity is often associated with other neurological conditions. A: Blurred vision This symptom arises from the anticholinergic blockade affecting ocular muscles and accommodation, leading to visual disturbances commonly reported by patients on tricyclic antidepressants. B: Difficulty starting urine stream This issue is linked to the anticholinergic effects that impede bladder function, resulting in challenges with urination, particularly evident in those taking tricyclic medications. C: Dry mouth Anticholinergic medications reduce saliva production, causing dry mouth, which is a well-documented side effect associated with the use of tricyclic antidepressants in clinical practice.
