Chapter 15 : Antiparkinson Drugs Questions
Question 1 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 2 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 3 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.
Question 4 of 5
While a patient is receiving drug therapy for Parkinson's disease, the nurse monitors for dyskinesia, which is manifested by which finding?
Correct Answer: B
Rationale: Dyskinesia, a common side effect of Parkinson's medications, manifests as difficulty in performing voluntary movements due to involuntary muscle activity. The other options describe different symptoms not typically associated with dyskinesia.
Question 5 of 5
When treating patients with medications for Parkinson's disease, the nurse knows that the wearing-off phenomenon occurs for which reason?
Correct Answer: C
Rationale: The wearing-off phenomenon occurs as antiparkinson medications, particularly levodopa, lose effectiveness over time due to disease progression, despite maximal dosing.
Tolerance, rapid response swings, or liver metabolism issues are not the primary causes.
