Gamma-aminobutyric acid
The nurse is providing information to a patient recently prescribed entacapone. Which statement is correct ?
Dosage is adjusted according to the patient’s response
The nurse is assessing an older patient with Parkinson’s disease who was startedon entacapone 1 week ago.

“A levodopa/carbidopa combination is used to improve motor function”
A nursing student wants to know how carbidopa can be effective for treating Parkinson disease if it prevents the conversion of levodopa to dopamine. the nurse explains that carbidopa:
does not cross the blood-brain barrier
A patient newly diagnosed with Parkinson disease is prescribed an oral dopamine agonist. Which precaution is most important to teach the patient and family about the timing for taking this drug?

A patient newly diagnosed with Parkinson disease has been taking levodopa/carbidopa for several weeks and complains of nausea and vomitting. The nurse tells the patient to discuss what with the provider?

Why are carbidopa and levodopa usually given together?
Carbidopa enhances the action of levodopa, and less drug is needed
How does the drug tolcapone relieve symptoms of Parkinson disease
Suppresses the activity of an enzyme that normally breaks down naturally occurring dopamine
A patient with Parkinson disease is taking levodopa/carbidopa along with amantadine 400 mg/day to treat dyskinesias. The patient reports having increased dyskinesias several months after beginning the amantadine. The nurse will contact the provider to discuss which action?
