Specific Neurodegenerative Disorders
8 The nurse is providing education to a patient taking carbidopa-levodopa. Which statement by the nurse correctly explains why the patient should take this medication with low-protein foods? "A high-protein diet will increase renal excretion of carbidopa-levodopa." "Low-protein foods accelerate the transportation of this medication to the CNS." "Alow-protein diet will help prevent gastrointestinal distress from the medication." "High-protein foods interfere with transportation of this medication to the central nervous system."
"High-protein foods interfere with transportation of this medication to the central nervous system." High-protein foods interfere with the transportation of the medication to the central nervous system. Patients taking carbidopa-levodopa should limit their intake of dietary protein.
A family member states, "My father complains of an upset stomach after taking rivastigmine." Which would be an appropriate response by the nurse? "We may need to decrease his dose." "Make sure he takes the medication with food." "Make sure he takes the medication without food." "We may need to reduce the frequency of his dosing to once daily."
"Make sure he takes the medication with food." Administering rivastigmine with food enhances absorption and reduces GI effects.
Which information related to rivastigmine should the nurse teach Mrs. Hill? "Weight gain can occur." "Avoid grapefruit products." "Take ibuprofen 30 minutes before a meal to prevent GI upset." "Rise slowly from sitting or lying positions, as orthostatic hypotension can occur."
"Rise slowly from sitting or lying positions, as orthostatic hypotension can occur." Orthostatic hypotension is a potential side effect of rivastigmine.
During patient discharge, a family member states to the nurse, "My mother's Alzheimer's disease can be cured." How should the nurse respond? "The disease cannot be slowed." "You are likely to develop this disease." "Everyone over 65 develops some level of this disease." "The symptoms may be treated, but the disease itself cannot be cured."
"The symptoms may be treated, but the disease itself cannot be cured." There are many physiologic symptoms of Alzheimer's disease that can be treated with medication, but there is no cure for the disease.
A patient who is currently taking an antihypertensive drug for renal artery stenosis has also been prescribed carbidopa-levodopa for the beginning stages of Parkinson's disease. The patient states, "I'm applying for a job where I would be operating a backhoe." What teaching should the nurse provide for the patient? "Perform exercises for lumbar support while sitting." "Your tremors will stop, so you will be able to operate a backhoe." "These medications stimulate your central nervous system, so you will be able to operate heavy machinery." "These medications together may increase your risk for hypotension, so you will need to use caution when operating heavy machinery."
"These medications together may increase your risk for hypotension, so you will need to use caution when operating heavy machinery." Taking an antihypertensive in combination with carbidopa-levodopa can result in hypotension. Patients using both medications should use caution when operating heavy machinery.
Which instruction is most important for the nurse to include when teaching a patient who has been prescribed sustained-released carbidopa-levodopa? "Take this medication with food." "Take this medication with low-protein foods." "Watch for adverse effects such as dizziness and drowsiness." "Inform the health care provider when you can walk without shuffling."
"Watch for adverse effects such as dizziness and drowsiness." Adverse effects of carbidopa-levodopa include dizziness and drowsiness, which can lead to orthostatic hypotension and falls. Safety is the highest priority.

16 The nurse is preparing to administer rivastigmine to a patient who has been admitted with worsening symptoms of Alzheimer's disease. The order states to administer 8 mg bid, and the pharmacy sends four 2-mg tablets for the am dose. What should the nurse do first? Administer the medication Call the pharmacy to ask for one 8 mg tablet Call the health care provider for an order change Ask a family member what dosage the patient takes at home
Call the health care provider for an order change The maximum dose of rivastigmine is 6 mg bid.
3 Which statement about the mechanism of action of carbidopa is true? Carbidopa has no therapeutic effect on its own. Carbidopa works by crossing the blood-brain barrier. Carbidopa aids in the breakdown of levodopa in the peripheral tissues. Due to periphery loss of the medication, only 2% of carbidopa taken is available to the brain.
Carbidopa has no therapeutic effect on its own. Carbidopa has no therapeutic effect of its own; it is used to enhance the effects of levodopa.
Which statement correctly explains the action of carbidopa-levodopa? Carbidopa decreases symptoms of parkinsonism. Carbidopa inhibits the breakdown of dopamine at the synapses in the brain. Carbidopa inhibits the catechol-o-methyltransferase (COMT) enzyme, increasing the concentration of levodopa. Carbidopa prevents levodopa decarboxylation in the periphery, resulting in more levodopa being transported to the brain.
Carbidopa prevents levodopa decarboxylation in the periphery, resulting in more levodopa being transported to the brain. With the use of carbidopa, less levodopa is needed. Carbidopa has no therapeutic effect of its own.
2 Which statement about carbidopa-levodopa is correct? Carbidopa-levodopa should not be taken with food. Carbidopa-levodopa should not be stopped abruptly. High-protein foods should be consumed with every meal. A decrease in the symptoms of Parkinson's disease occurs within a week of starting medication treatment.
Carbidopa-levodopa should not be stopped abruptly. Discontinuing use of carbidopa-levodopa abruptly can result in rebound parkinsonism.
What potential side effect of carbidopa-levodopa should the nurse teach the patient and family to report to the health care provider? GI upset Seizures Dyskinesia Elevated temperature
Dyskinesia Dyskinesia (involuntary muscle movement) may occur with high levodopa dosages and should be reported.
5 Which nursing diagnosis is highest priority for a nurse who is caring for a patient taking carbidopa-levodopa for Parkinson's disease? Risk for activity intolerance related to tremors Impaired physical mobility related to dizziness Body image disturbance related to shuffling gait Knowledge deficit related to effects of medication
Impaired physical mobility related to dizziness Impaired physical mobility related to dizziness is the highest priority. Patients are at higher risk for falls when they are dizzy.
To evaluate the effectiveness of dopaminergic agents, the nurse should assess for which condition? Weight loss Correction of shuffling gait Increase in drooling and sweating Improvement in balance, gait, and mobility
Improvement in balance, gait, and mobility The effectiveness of dopaminergic agents is evaluated by their control of parkinsonism symptoms. An improvement in balance, gait, and mobility indicates controlled parkinsonism symptoms.
15 A nurse is evaluating the effectiveness of an Alzheimer patient's drug regimen. Which assessment finding by the nurse would indicate that the medicine is effective? Increase in wandering Absence of side effects No increase in ALT and AST Improvement in mental status
Improvement in mental status Ongoing evaluation of controlled Alzheimer's disease symptoms helps determine if an increase in dosage or change in medication is needed. An improvement in mental status from the baseline assessment indicates the medication is having a therapeutic effect.
Which statement best explains the therapeutic effect of rivastigmine? Improves memory Restores damaged neurons Improves oxygenation in the brain Increases antioxidants in the brain
Improves memory Rivastigmine improves memory in patients with mild to moderate Alzheimer's disease.
6 A patient has been taking carbidopa-levodopa for many years. During assessment, the nurse finds that the patient presents with hand tremors, drooling, and a mask-like facial expression. What action by the health care provider should the nurse anticipate? Increase in medication dosage Decrease in medication dosage Discontinuation of the medication Discussion of medication compliance
Increase in medication dosage Ongoing evaluation of controlled Parkinson's disease symptoms helps the health care provider determine if an increase in dosage or change in medication is needed. After many years of use, carbidopa-levodopa may lose its overall effectiveness.
The nurse is caring for a patient who has a history of COPD and a new diagnosis of Alzheimer's disease. The nurse knows that theophylline and rivastigmine have what effect on the patient when given together? Increase potassium levels Decrease blood glucose levels Increase the risk for theophylline toxicity Increase the risk for rivastigmine toxicity
Increase the risk for theophylline toxicity Rivastigmine can increase the effects of theophylline and increase the patient's risk for theophylline toxicity.
