A nurse is caring for a client who has Parkinson's disease and is prescribed an anticholinergic. Which of the following therapeutic outcomes should the nurse expect to see?

Relief of depression Incorrect because anticholinergics do not have antidepressant effects and may worsen depression by causing sedation, confusion or hallucinations. Decreased tremors Correct because anticholinergics block the action of acetylcholine in the brain and reduce the imbalance between dopamine and acetylcholine that causes tremors in Parkinson's disease. Delay in disease progression Incorrect because anticholinergics do not modify the underlying pathology of Parkinson's disease and do not prevent neuronal degeneration or dopamine depletion. Improved bladder function Incorrect because anticholinergics may impair bladder function by causing urinary retention, hesitancy or incontinence due to their antispasmodic effects on the detrusor muscle.
