What finding would be of most concern if you are preparing to administer levodopa?

A. Ataxia, or loss of coordination, is a concerning finding when administering levodopa because it may indicate excessive dopaminergic activity, which can increase the risk of falls, injury, or severe motor side effects. Levodopa can cause dyskinesias, orthostatic hypotension, and balance problems, so ataxia requires immediate assessment and possible dose adjustment by the provider. B. Dizziness with position changes is a common side effect due to orthostatic hypotension from levodopa. While nurses should monitor and provide safety measures (like rising slowly), this is less immediately concerning than ataxia. C. Dark-colored urine is a harmless side effect of levodopa and does not indicate toxicity or adverse CNS effects. Patients should be educated to expect this change and reassured. D. Tics or minor involuntary movements can occur as mild dyskinesias from levodopa, but isolated tics are generally less critical than ataxia, unless they interfere with safety or become severe.
