1. A patient is experiencing an autoimmune response where antibodies are directed
against acetylcholine receptors at the neuromuscular junction. Which condition is
most consistent with this pathophysiology?
A) Multiple sclerosis
B) Guillain-Barré syndrome
C) Myasthenia gravis
D) Parkinson disease
Correct Answer: C) Myasthenia gravis
Rationale: Myasthenia gravis is a chronic autoimmune disease mediated by
antibodies that attack acetylcholine (ACh) receptors at the neuromuscular junction.
These antibodies prevent normal ACh binding and muscle contraction, leading to
characteristic muscle weakness that worsens with activity and improves with rest.
Multiple sclerosis involves autoimmune demyelination in the central nervous
system. Guillain-Barré syndrome is an autoimmune attack on peripheral nerves,
often triggered by infection. Parkinson disease results from dopamine deficiency in
the basal ganglia.
2. The parasympathetic nervous system is primarily responsible for which of the
following functions?
A) Preparing the body for "fight or flight" responses
,B) Conserving energy and maintaining body resources
C) Redirecting blood flow to skeletal muscles during stress
D) Increasing heart rate and blood pressure during emergencies
Correct Answer: B) Conserving energy and maintaining body resources
Rationale: The parasympathetic nervous system is responsible for conserving
energy and the body's resources, supporting "rest and digest" functions such as
digestion, metabolism, and maintenance of day-to-day homeostasis. The
sympathetic nervous system is responsible for the "fight or flight" response,
including redirecting blood flow to muscles and increasing heart rate.
3. A patient with a spinal cord injury at the T5 level suddenly develops paroxysmal
hypertension (systolic BP 280 mmHg), a pounding headache, bradycardia (HR 32
bpm), and flushing above the level of the lesion. What is the most likely diagnosis?
A) Autonomic dysreflexia
B) Orthostatic hypotension
C) Neurogenic shock
D) Hypertensive crisis
Correct Answer: A) Autonomic dysreflexia
Rationale: Autonomic dysreflexia is characterized by paroxysmal hypertension (up
to 300 mmHg systolic), pounding headache, blurred vision, sweating above the
lesion level with flushing, nasal congestion, nausea, piloerection, and bradycardia
(30-40 bpm). This condition occurs in individuals with spinal cord lesions at or
above the T5-T6 level. The intact autonomic nervous system reflexively responds
to a noxious stimulus below the level of injury with arteriolar spasm and
hypertension, but efferent impulses cannot pass through the cord to allow
vasodilation.
,4. In Guillain-Barré syndrome, the typical progression of symptoms begins with:
A) Respiratory distress and difficulty swallowing
B) Diplopia, ptosis, and ocular palsies
C) Numbness, pain, paresthesias, or weakness in the limbs
D) Cognitive decline and memory impairment
Correct Answer: C) Numbness, pain, paresthesias, or weakness in the limbs
Rationale: The typical first manifestations of Guillain-Barré syndrome are
numbness, pain, paresthesias, or weakness in the limbs. Paresis or paralysis may
present in an ascending pattern. This autoimmune disease typically presents 2-4
weeks following a bacterial or viral infection, such as respiratory or
gastrointestinal illness. Respiratory distress and difficulty breathing are later signs
of disease progression.
5. A patient with Guillain-Barré syndrome shows no signs of improvement after
three months. What does this suggest about the prognosis?
A) The patient is still in the acute phase
B) It may indicate a poor prognosis
C) Improvement will occur within days
D) The patient will recover completely
Correct Answer: B) It may indicate a poor prognosis
Rationale: Weakness in Guillain-Barré syndrome typically plateaus or improves by
the 4th week in 90% of cases. If a patient shows no signs of improvement after
three months, this may indicate a poor prognosis. Most individuals experience
, gradual improvement over several weeks to months; recovery is not instantaneous,
and some patients may have residual deficits.
6. Which statement best describes the progression of multiple sclerosis (MS)?
A) The primary mechanism involves overproduction of neurotransmitters
B) The disease is characterized by demyelination of nerve fibers in the central
nervous system
C) MS only affects the peripheral nervous system
D) The diagnosis is confirmed by genetic testing
Correct Answer: B) The disease is characterized by demyelination of nerve fibers
in the central nervous system
Rationale: Multiple sclerosis is characterized by demyelination of nerve fibers in
the central nervous system (CNS). As the disease progresses, inflammatory
changes in the CNS increase, and loss of brain volume progresses more rapidly.
Demyelination disrupts sodium, calcium, and potassium ion channels. Activated
microglia and macrophages release nitric oxide and free radicals. A definitive
diagnosis of MS requires postmortem examination; clinical diagnosis involves
ruling out other causes.
7. What are the proposed protective factors for Alzheimer's disease?
A) High-calorie diets and sedentary lifestyle
B) Estrogen replacement at time of menopause, NSAIDs, and physical activity
C) Increased sodium intake and smoking
D) High-fat diets and alcohol consumption
Correct Answer: B) Estrogen replacement at time of menopause, NSAIDs, and
physical activity
