The nurse is teaching a patient who has Parkinson's disease about the side effects of carbidopa-levodopa. Which statement by the patient indicates a need for further teaching?

A. "I may experience urinary retention, dry mouth, and constipation." This statement is accurate. Urinary retention, dry mouth, and constipation are common side effects of carbidopa-levodopa. The patient should be aware of these potential side effects and report them to the healthcare provider if they become problematic. B. "I may feel dizzy at first, but this side effect will go away with time." This statement is accurate. Dizziness is a common initial side effect of carbidopa-levodopa, and it often improves with continued use. The patient should be encouraged to report persistent dizziness to the healthcare provider. C. "I should report nightmares and mental disturbances to my provider." This statement is accurate. Nightmares and mental disturbances can be side effects of carbidopa-levodopa. The patient should report these symptoms to the healthcare provider for further evaluation and potential adjustments to the medication. D. "I should take the drug with food to increase absorption." This statement indicates a need for further teaching. Carbidopa-levodopa is best absorbed when taken on an empty stomach. Taking it with food, especially high-protein meals, can reduce its absorption. The patient should be instructed to take the medication at least 30 minutes before meals or one to two hours after meals for optimal effectiveness.
