Chapter 15 : Antiparkinson Drugs Questions
Question 1 of 5
A patient has been given a prescription for carbidopa-levodopa for a new diagnosis of Parkinson's disease. The patient asks the nurse, 'Why are there two drugs in this pill?' The nurse's best response reflects which fact?
Correct Answer: B
Rationale: Carbidopa inhibits peripheral breakdown of levodopa, increasing its availability to the CNS and allowing lower doses with fewer side effects. Carbidopa is not a dopamine precursor, and the combination does not eliminate drug-food interactions.
Question 2 of 5
When a patient is taking an anticholinergic such as benztropine as part of the treatment for Parkinson's disease, the nurse should include which information in the teaching plan?
Correct Answer: D
Rationale: Anticholinergics like benztropine cause dry mouth, which can be managed with artificial saliva, sugarless gum, or hard candy. Patients should increase fluid intake to prevent constipation and dehydration, take the drug with meals to reduce GI upset, and avoid abrupt discontinuation.
Question 3 of 5
A patient has been treated with antiparkinson medications for 3 months. What therapeutic responses should the nurse look for when assessing this patient?
Correct Answer: D
Rationale: Therapeutic effects of antiparkinson drugs include improved ability to perform daily activities, better mental status, and reduced parkinsonian symptoms. Decreased appetite and cogwheel rigidity are not therapeutic, and dyskinesias are adverse effects.
Question 4 of 5
Carbidopa-levodopa is prescribed for a patient with Parkinson's disease. The nurse informs the patient that which common adverse effects can occur with this medication?
Correct Answer: D
Rationale: Common adverse effects of carbidopa-levodopa include palpitations, hypotension, urinary retention, dyskinesias, and depression. The other options list effects more associated with other antiparkinson drugs.
Question 5 of 5
The nurse is assessing the medication history of a patient with a new diagnosis of Parkinson's disease. Which condition is a contraindication for the patient, who will be taking entacapone?
Correct Answer: C
Rationale: Entacapone is contraindicated in liver failure due to its hepatic metabolism, which could lead to toxicity. Glaucoma, seizure disorders, and benign prostatic hyperplasia are not absolute contraindications for entacapone.
