A patient with Parkinson's disease is prescribed Carbidopa/Levodopa. Which of the following statements by the nurse is most accurate regarding this medication?
"You should abruptly stop taking this medication if you experience nausea."
"This medication may cause involuntary movements as a side effect."
"You should take this medication with a high-protein meal to enhance absorption."
"This medication will improve your memory and cognitive function."
The Correct Answer is B
A. "You should abruptly stop taking this medication if you experience nausea.": Abrupt discontinuation of Carbidopa/Levodopa can lead to serious complications such as neuroleptic malignant-like syndrome. Nausea is a common early side effect and should be reported, not used as a reason to stop the medication suddenly.
B. "This medication may cause involuntary movements as a side effect.": Long-term use of Carbidopa/Levodopa can lead to dyskinesias, which are involuntary, erratic movements. These occur due to fluctuating dopamine levels and are a common motor complication in advanced Parkinson's disease.
C. "You should take this medication with a high-protein meal to enhance absorption.": High-protein meals can actually interfere with Levodopa absorption because dietary amino acids compete with the drug for transport across the blood-brain barrier. Protein intake should be evenly distributed throughout the day.
D. "This medication will improve your memory and cognitive function.": Carbidopa/Levodopa is primarily used to treat motor symptoms of Parkinson's disease by replenishing dopamine. It has minimal impact on cognitive symptoms and is not indicated for memory enhancement.

A. "Avoid alcohol while taking this medication as it may increase drowsiness.": Baclofen is a central nervous system depressant and can cause sedation. Alcohol can intensify this effect, increasing the risk of severe drowsiness, dizziness, or respiratory depression.
B. "You can abruptly stop taking this medication if you don't notice improvement.": Abrupt discontinuation of Baclofen can lead to withdrawal symptoms such as hallucinations, seizures, and rebound spasticity. The medication should be tapered under medical supervision.
C. "Baclofen doesn't cause drowsiness, so you can continue your normal activities without any restrictions.": Baclofen often causes drowsiness and dizziness, especially when therapy is initiated. Patients should be cautious with activities requiring alertness, such as driving.
D. "Take this medication only when you experience muscle spasms:": Baclofen is typically taken on a regular schedule to maintain therapeutic levels and control muscle spasms continuously. It is not used on an as-needed basis.
