Chapter 15 : Antiparkinson Drugs Questions
Question 1 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 2 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.
Question 3 of 5
The nurse is developing a care plan for a patient who is taking an anticholinergic drug. Which human needs statement would be appropriate for this patient?
Correct Answer: B
Rationale: Anticholinergic drugs like benztropine can cause urinary retention and constipation, making altered urinary elimination the appropriate human needs statement. Diarrhea, infection risk, and sleep needs are not typically affected.
Question 4 of 5
A patient who has been on levodopa therapy for a year has a new order for a catechol ortho-methyltransferase (COMT) inhibitor as part of treatment for Parkinson's disease. The nurse recognizes that which of these is an advantage of this drug class?
Correct Answer: D
Rationale: COMT inhibitors like entacapone extend levodopa's duration, reducing the wearing-off phenomenon. They do not have a shorter duration, less GI distress, or slower onset compared to other antiparkinson drugs.
Question 5 of 5
A patient taking entacapone for the first time calls the clinic to report a dark discoloration of his urine. After listening to the patient, the nurse realizes that what is happening in this situation?
Correct Answer: A
Rationale: Entacapone commonly causes harmless dark discoloration of urine and sweat, which does not indicate an allergic reaction, interaction with tyramine-containing foods, or an excessive dose.
