Introduction
The NR507 Advanced Pathophysiology Final Examination
evaluates the graduate nursing student's ability to integrate
complex disease mechanisms across multiple body systems,
with emphasis on Weeks 5 through 8 content. It assesses
neurological, cardiovascular, renal, endocrine, pulmonary,
hematologic, and gastrointestinal pathophysiology alongside
,cellular injury and inflammatory processes. The examination
uses multiple-choice and scenario-based questions to
measure clinical reasoning, mechanism-based decision-
making, and real-world application. Candidates must
demonstrate competency in connecting laboratory findings,
clinical manifestations, and underlying pathophysiological
principles to ensure safe and effective advanced practice
nursing care.
SECTION ONE: QUESTIONS 1–100
1. Which neurotransmitter is primarily deficient in the
substantia nigra in Parkinson's disease?
A. Serotonin
B. Dopamine
C. Acetylcholine
D. Gamma-aminobutyric acid (GABA)
🟢 B. Dopamine
🔴 RATIONALE: Parkinson's disease results from
degeneration of dopamine-producing neurons in the
substantia nigra pars compacta of the basal ganglia, leading
to the classic motor symptoms of tremor, rigidity,
bradykinesia, and postural instability.
,2. A patient presents with a sudden "worst headache of my
life" and neck stiffness. Which condition is most likely?
A. Ischemic stroke
B. Subarachnoid hemorrhage
C. Epidural hematoma
D. Transient ischemic attack
🟢 B. Subarachnoid hemorrhage
🔴 RATIONALE: A thunderclap headache with meningeal
irritation (neck stiffness, photophobia) is the classic
presentation of subarachnoid hemorrhage, most often from
a ruptured berry aneurysm.
3. In the Gate Control Theory of pain, which fibers inhibit
pain transmission by "closing the gate"?
A. C fibers
B. A-delta fibers
C. A-beta fibers
D. Sympathetic fibers
🟢 C. A-beta fibers
🔴 RATIONALE: Large-diameter, myelinated A-beta fibers
carry non-noxious tactile stimuli and, when activated, inhibit
transmission of pain signals in the dorsal horn, effectively
"closing the gate" to pain.
, 4. Which type of cerebral edema results from breakdown
of the blood-brain barrier after stroke or tumor?
A. Cytotoxic edema
B. Vasogenic edema
C. Interstitial edema
D. Osmotic edema
🟢 B. Vasogenic edema
🔴 RATIONALE: Vasogenic edema is caused by increased
permeability of capillary endothelial tight junctions after
blood-brain barrier injury, allowing protein-rich fluid to leak
into the extracellular space.
5. The hallmark pathophysiological feature of Alzheimer's
disease is:
A. Dopaminergic depletion in the basal ganglia
B. Demyelination of central axons
C. Amyloid-beta plaques and tau neurofibrillary tangles
D. Prion protein accumulation
🟢 C. Amyloid-beta plaques and tau neurofibrillary tangles
🔴 RATIONALE: Alzheimer's disease is characterized by
extracellular amyloid-beta plaques and intracellular
hyperphosphorylated tau neurofibrillary tangles, leading to
synaptic dysfunction and neuronal loss.
