Carbidopa-levodopa (Sinemet) is prescribed for a client with Parkinson's disease, and the nurse monitors the client for adverse reactions to the medication. Which of the following indicates that the client is experiencing an adverse reaction? 1. Pruritus 2. Tachycardia 3. Hypertension 4. Impaired voluntary movements

4. Impaired voluntary movements Rationale: Dyskinesia and impaired voluntary movement may occur with high levodopa dosages. Nausea, anorexia, dizziness, orthostatic hypotension, bradycardia, and akinesia (the temporary muscle weakness that lasts 1 minute to 1 hour, also known as the "on-off phenomenon") are frequent side effects of the medication.

When teaching a patient about carbidopa-levodopa (Sinemet), the nurse responds based on knowledge that A) carbidopa decreases levodopa's conversion in the periphery, increasing the levodopa available to cross the blood-brain barrier. B) carbidopa increases levodopa's conversion in the periphery, enhancing the amount of dopamine available to the brain. C) giving both drugs together minimizes side effects. D) carbidopa crosses the blood-brain barrier to increase the metabolism of levodopa to dopamine in the brain

A) carbidopa decreases levodopa's conversion in the periphery, increasing the levodopa available to cross the blood-brain barrier.

The patient asks the nurse to explain the difference between carbidopa-levodopa (Sinemet) and ropinirole (Requip). The nurse's response is based on knowledge that A) ropinirole is a dopamine agonist that has fewer side effects than carbidopa-levodopa. B) carbidopa-levodopa is less effective than ropinirole in treating the symptoms of Parkinson's disease. C) both drugs have the same pharmacodynamic and side effect profiles. D) carbidopa-levodopa acts as a dopamine agonist, whereas ropinirole directly replaces dopamine.

A) ropinirole is a dopamine agonist that has fewer side effects than carbidopa-levodopa.

Which comment to the nurse indicates more teaching is needed for a client taking carbidopa/levodopa?

Answer: "I know I need to take this drug once a day." Rationale: A statement from the client such as "I know I need to take this drug once a day" indicates that more teaching is needed because carbidopa/levodopa has a short half-life and must be taken 3 or 4 times per day. The other answers are true.

Which side effect/adverse effect of carbidopa/levodopa does the nurse realize is most important to monitor? A. Agranulocytosis B.Dysphagia C. Increased Libido D. Urinary Retention

Answer: Agranulocytosis Rationale: It is most important for the nurse to monitor the client taking carbidopa/ levodopa for agranulocytosis (decreased white blood cells), which is life-threatening. Dysphagia, increased libido, and urinary retention are not life threatening.

The patient with Parkinson's disease who has been positively responding to carbidopa-levodopa (Sinemet) suddenly develops a relapse of symptoms. Which explanation by the nurse is appropriate? A) "You have obviously developed resistance to your current medication and will have to be switched to another drug." B) "This is an atypical response. Unfortunately, there are no other options of drug therapy to give you." C) "This is called the 'on-off phenomenon.' Your health care provider can change your medication regimen slightly to help diminish this effect." D) "You just need to keep taking your medication and these effects will go away."

C) "This is called the 'on-off phenomenon.' Your health care provider can change your medication regimen slightly to help diminish this effect."

What is the goal of pharmacologic therapy in treating Parkinson's disease? A) Increase the amount of acetylcholine at the presynaptic neurons. B) Decrease the amount of dopamine available in the substantia nigra. C) Balance cholinergic and dopaminergic activity in the brain. D) Block dopamine receptors in both presynaptic and postsynaptic neurons

C) Balance cholinergic and dopaminergic activity in the brain.

The nurse is caring for a patient with Parkinson's disease. The patient has been taking entacapone (Comtan) for the past week to treat an on-off phenomenon. The patient expresses concern over brownish-orange urine. The nurse's response is based on the knowledge that A) the patient may be developing renal failure. B) the patient may be developing hepatic failure. C) brownish-orange urine signifies a lack of fluid intake. D) this is a normal occurrence related to entacapone (Comtan).

D) this is a normal occurrence related to entacapone (Comtan).

A patient is prescribed a dopamine agonist, pramipexole (Mirapex). Which statement made by the patient indicates a need for further teaching? A.

"This drug will stop the progression of Parkinson's disease."
