Parkinson disease (PD) is a progressive neurodegenerative disorder caused by dopaminergic neuron loss in the substantia nigra, producing the cardinal motor triad of resting tremor, rigidity, and bradykinesia. In hospitalized patients, missed or delayed levodopa doses are the single most dangerous nursing error — even a 30-minute delay can precipitate akinetic crisis (complete motor freezing), aspiration, and inability to swallow subsequent doses. The NCLEX trap: nurses assume scheduled medications can be safely deferred until after routine procedures or meals; in PD, levodopa timing is as urgent as insulin. Top 3 nursing priorities: 1. Administer levodopa/carbidopa at the exact scheduled time — never hold without explicit neurologist order 2. Assess swallowing function before oral medications; dysphagia risk is highest in the "off" state 3. Protect from falls — postural instability and freezing episodes peak during "off" periods On the exam, writers often pair stable-sounding options with unstable data—notice the mismatch before you commit. If the stem names a license or role, reread that line; scope errors are classic trap answers even when the clinical topic is familiar. Run a 60-second scan:...
