1. Which of the following is a common characteristic of neurodegenerative disorders?
● Rapid progression and immediate onset of symptoms
● Primarily affecting the peripheral nervous system
● Progressive loss of structure or function of neurons
● Reversible neurological deficits
Your response is correct!
Neurodegenerative disorders are primarily characterized by the progressive degeneration of the
structures and functions of the brain (not the peripheral nervous system), especially neurons. This
process is usually gradual and worsens over time (not rapidly), leading to irreversible (not
reversible) symptoms, including memory loss, impaired judgment, and motor dysfunction.
2. Which of the following are risk factors for developing neurodegenerative disorders?
Select all that apply.
● Exposure to certain environmental toxins
● History of traumatic brain injuries
● Genetic predisposition
● Aging
● High levels of physical activity in early adulthood
Your response is correct!
Genetic predisposition and aging are well-known risk factors for neurodegenerative disorders. As
individuals age, the risk of diseases like Alzheimer's and Parkinson's increases. Exposure to
environmental toxins has been linked to an increased risk of neurodegenerative diseases. History of
traumatic brain injuries is also considered a risk factor, particularly for conditions such as
Alzheimer's disease.
High levels of physical activity in early adulthood can reduce the risk of neurodegenerative
diseases.
3. Which neurodegenerative disorder is primarily caused by the destruction of
dopaminergic neurons in the substantia nigra of the brain?
● Amyotrophic lateral sclerosis (ALS)
● Huntington's disease
● Parkinson's disease
● Alzheimer's disease
Your response is correct!
Parkinson's disease is caused by the progressive loss of dopamine-producing neurons in the
substantia nigra. This loss leads to the primary symptoms of Parkinson's, such as tremors, rigidity,
bradykinesia (slowness of movement), and postural instability.
Although the other options are neurodegenerative diseases, they exhibit different
pathophysiological characteristics.
, 4. Which of the following are risk factors and clinical manifestations associated with
Alzheimer's disease (AD)? Select all that apply.
● Increased social engagement
● Family history of AD
● Frequent and unexplained mood changes
● Age over 65 years
● Challenges in planning or solving problems
● Difficulty remembering newly learned information
● Improved or unchanged short-term memory
Your response is correct!
AD is more commonly diagnosed in individuals aged over 65, making advanced age a significant
risk factor. A family history of AD can increase an individual's risk due to genetic factors. Among the
clinical manifestations of AD, difficulty in remembering newly learned information is often one of the
earliest symptoms. As the disease progresses, affected individuals may face challenges in planning
or solving problems. Frequent and unexplained mood changes are also observed in many cases,
reflecting the impact of AD on emotional regulation and mental health.
Increased social engagement is protective against AD. Improved or unchanged short-term memory
is typically not characteristic of AD, as the disease usually leads to a decline in short-term memory
capabilities.
5 . The nurse practitioner (NP) is selecting diagnostic tests to order for a client
suspected of having Alzheimer’s disease. Match the diagnostic test with the rationale
for use in this client.
● May reveal brain atrophy and exclude other causes of dementia → Neuroimaging
● Used to assess cognitive function and severity of dementia → Mini-Mental State
Examination (MMSE)
● Can identify rare genetic mutations associated with Alzheimer’s → Genetic
testing
● Often used to rule out vitamin deficiencies and thyroid issues → Blood tests
● May identify substances that can cause symptoms of dementia → Medication
review
Your response is correct!
Neuroimaging can be used to reveal brain atrophy in Alzheimer’s disease or to rule out other
causes of dementia. The Mini-Mental Status Examination (MMSE) can be used to assess cognitive
function and the severity of dementia. Genetic testing can be used to identify genetic mutations that
may lead to early Alzheimer’s disease. Blood tests can be used to test for other causes of
dementia. Medication review is important to identify substances that can cause symptoms of
dementia.
, 6 . A nurse practitioner (NP) is caring for a client suspected to have Parkinson's disease
(PD). Based on the pathophysiology of PD, select the clinical manifestations the NP
should anticipate. Select all that apply.
● Postural instability
● Bradykinesia
● Hyperreflexia
● Increased dopamine levels
● Tremor at rest
● Muscle rigidity
Your response is correct!
A resting tremor, bradykinesia, muscle rigidity, and postural instability are all common signs and
symptoms of Parkinson’s disease (PD).
Increased dopamine levels and hyperreflexia are not typical signs or symptoms of (PD).
7 . A 72-year-old client with a suspected diagnosis of Parkinson's disease (PD) is
administered a test dose of levodopa. Which of the following indicates the
effectiveness of levodopa in this client?
● Increase in heart rate and blood pressure
● Improvement in motor symptoms
● Signs of allergic reactions
● Improved cognitive function
Your response is correct!
Levodopa is a medication used to manage the motor symptoms of PD. A positive response to a test
dose of levodopa is a noticeable improvement in motor symptoms, which validates a diagnosis of
PD.
Although it is important to monitor for side effects, allergic reactions, and changes in cognitive
function, the primary purpose of the test dose is to assess its impact on motor symptoms.
8 . A nurse practitioner (NP) is caring for several clients with different neurodegenerative
conditions. Match each client with the most likely neurodegenerative condition based
on the described symptoms.
● Client 1: Progressive memory loss, especially recent memory; difficulty with
complex tasks and planning; changes in mood and behavior → Alzheimer’s disease
● Client 2: Asymmetric resting tremor; bradykinesia; muscle rigidity → Parkinson’s
disease
● Client 3: Gradual muscle weakness and wasting; difficulty speaking and swallowing;
respiratory muscle weakness → ALS (Amyotrophic Lateral Sclerosis)
9. Question
Hugo Pedroso (pronouns he/him/his), 70 years old, presents with many complaints. The
nurse practitioner (NP) should associate which symptoms that, taken together, are indicative
of a neurodegenerative disorder of motor function, such as Parkinson's disease (PD)? Select
all that apply.
, ● Early cognitive decline
● Muscle rigidity
● Shuffling gait
● Intermittent claudication
● Muscle weakness and atrophy
● Resting tremor
Your response is correct!
Shuffling gait, resting tremor, and muscle rigidity are classic symptoms associated with PD, a
common neurodegenerative disorder impacting motor function.
Intermittent claudication is more commonly associated with peripheral arterial disease. Early
cognitive decline is more common in Alzheimer’s or Huntington’s disease, both of which are
cognitive neurodegenerative disorders. Muscle weakness and atrophy are more indicative of
Amyotrophic Lateral Sclerosis (ALS).
9. Question
In addition to the primary motor symptoms, which of the following non-motor symptoms are
relevant in assessing for Parkinson's disease (PD)? Select all that apply.
● Depression
● Sleep disturbances
● Increased olfactory function
● Cognitive impairment
● Constipation
Your response is correct!
Cognitive impairment, sleep disturbances, constipation, and depression are all common non-motor
symptoms of PD. Increased ability to smell is not a non-motor symptom of PD.
Question - at which point the following symptoms appear during the progression of
Parkinson's disease (PD). Each row will have one response.
● Resting tremor → Clinical Onset
● Cognitive impairment → Late Stage
