Neurological Disorders (Questions 1-30)
1. A patient with Alzheimer's disease is in the moderate stage. Which
finding would the nurse expect?
a) Forgets names but can still live independently
b) Total incapacitation and bedridden status
c) Disorientation to time and place, with possible incontinence
d) Subtle personality changes only
Correct Answer: c) Disorientation to time and place, with possible
incontinence
Rationale: The moderate stage of Alzheimer's is characterized by a progression
beyond memory loss to include disorientation, difficulty with complex tasks,
incontinence, and the emergence of psychotic behaviors like hallucinations.
Total incapacitation is a feature of the late stage, while forgetting names and
subtle changes occur in the mild stage.
2. The nurse is teaching a family about apraxia in Alzheimer's disease. The
nurse should explain that apraxia is:
,a) The inability to recognize familiar objects or faces
b) Difficulty finding the right word to name an object
c) A loss of sensory comprehension
d) Difficulty with motor planning to perform tasks
Correct Answer: d) Difficulty with motor planning to perform tasks
Rationale: Apraxia is a neurological disorder where the patient cannot execute
learned, purposeful movements despite having the physical ability and desire to
do so. An example is being unable to brush their hair, even though they
understand the command and can hold the brush. Agnosia is the inability to
recognize objects, anomia is difficulty naming objects, and aphasia is a broader
language impairment.
3. The definitive diagnosis of Alzheimer's disease is confirmed by:
a) A positive MRI showing hippocampal shrinkage
b) Brain tissue examination at autopsy showing neurofibrillary tangles
c) A genetic test for the ApoE4 allele
d) A lumbar puncture showing low amyloid-beta levels
Correct Answer: b) Brain tissue examination at autopsy showing
neurofibrillary tangles
Rationale: While clinical diagnosis is based on symptoms and ruling out other
causes, the only definitive confirmation of Alzheimer's is postmortem
identification of the hallmark pathological features: neurofibrillary tangles and
neuritic plaques in the brain tissue. Other tests can support the diagnosis but
are not conclusive.
, 4. A patient with Parkinson's disease is prescribed Carbidopa/Levodopa
(Sinemet). The nurse understands that the purpose of Carbidopa is to:
a) Directly increase dopamine levels in the brain
b) Prevent the peripheral breakdown of Levodopa
c) Act as an anticholinergic to reduce tremors
d) Stimulate dopamine receptors in the substantia nigra
Correct Answer: b) Prevent the peripheral breakdown of Levodopa
Rationale: Levodopa is the precursor to dopamine and can cross the blood-
brain barrier. Carbidopa is a decarboxylase inhibitor that does not cross the
blood-brain barrier. It prevents the conversion of Levodopa to dopamine in the
periphery, reducing side effects like nausea and allowing more Levodopa to
reach the brain, where it can be converted to dopamine.
5. The "on-off" phenomenon in a patient with Parkinson's disease taking
Levodopa is best described as:
a) Severe dyskinesias that occur at the peak of medication effect
b) A cholinergic crisis caused by medication overdose
c) Sudden, unpredictable swings between mobility and immobility
d) The worsening of symptoms before the next dose is due
Correct Answer: c) Sudden, unpredictable swings between mobility and
immobility
Rationale: The "on-off" phenomenon is a motor fluctuation that occurs in
advanced Parkinson's. The "on" period is when the medication is working and
symptoms are controlled. The "off" period is a sudden, unpredictable return of
