Guide (Weeks 7–11, Latest 2025/2026) |
Walden University
Overview
This review guide covers key pathophysiology concepts from Weeks 7–11 for the NURS 6501
Final Exam at Walden University. It includes 78 questions with verified answers, focusing on
neurological, musculoskeletal, gastrointestinal, endocrine, and reproductive disorders. Each
question includes the correct answer in blue, followed by a detailed rationale. Use this guide for
the exam, which tests understanding of disease mechanisms, clinical manifestations, and
diagnostic approaches.
Questions 1–78: Advanced Pathophysiology (Weeks 7–11)
Neurological Disorders (Weeks 7–8)
1. What is the primary pathophysiological mechanism of ischemic stroke?
A. Hemorrhage into brain tissue
B. Blockage of cerebral blood flow
C. Increased intracranial pressure
D. Neurotransmitter imbalance
Answer: Blockage of cerebral blood flow
Rationale: Ischemic stroke results from occlusion of a cerebral artery, reducing blood
flow and causing neuronal ischemia.
2. What are clinical manifestations of a stroke in the left hemisphere? (Select all that
apply)
A. Right-sided weakness
B. Aphasia
C. Left-sided neglect
D. Visual field deficits
E. Emotional lability
, Answer: Right-sided weakness, Aphasia, Visual field deficits, Emotional lability
Rationale: Left hemisphere stroke affects language (aphasia), right-sided motor function,
and visual fields; emotional lability is common.
3. What is the hallmark feature of Parkinson’s disease?
A. Resting tremor
B. Seizures
C. Memory loss
D. Ataxia
Answer: Resting tremor
Rationale: Parkinson’s disease is characterized by resting tremor, bradykinesia, and
rigidity due to dopamine deficiency.
4. What is the pathophysiological cause of Parkinson’s disease?
A. Loss of dopamine-producing neurons in the substantia nigra
B. Amyloid plaque accumulation
C. Overproduction of acetylcholine
D. Cerebellar degeneration
Answer: Loss of dopamine-producing neurons in the substantia nigra
Rationale: Degeneration of substantia nigra neurons reduces dopamine, leading to motor
symptoms.
5. What is a common complication of traumatic brain injury (TBI)?
A. Hypoglycemia
B. Increased intracranial pressure
C. Hyperthyroidism
D. Bone fractures
Answer: Increased intracranial pressure
Rationale: TBI can cause cerebral edema or hematoma, increasing intracranial pressure.
6. What is the primary cause of seizures in epilepsy?
A. Hypokalemia
B. Abnormal neuronal excitability
C. Hypoglycemia
D. Hypernatremia
Answer: Abnormal neuronal excitability
Rationale: Seizures result from excessive or synchronous neuronal firing in the brain.
7. What is a clinical manifestation of multiple sclerosis (MS)?
A. Progressive memory loss
B. Optic neuritis
, C. Resting tremor
D. Peripheral neuropathy
Answer: Optic neuritis
Rationale: MS involves demyelination, causing symptoms like optic neuritis, weakness,
and sensory deficits.
8. What is the pathophysiological mechanism of Alzheimer’s disease?
A. Dopamine deficiency
B. Amyloid plaques and neurofibrillary tangles
C. Cerebellar atrophy
D. Loss of GABA neurons
Answer: Amyloid plaques and neurofibrillary tangles
Rationale: Alzheimer’s is characterized by amyloid-beta plaques and tau protein tangles,
leading to neuronal death.
9. What is a risk factor for hemorrhagic stroke?
A. Hypotension
B. Uncontrolled hypertension
C. Hypoglycemia
D. Low cholesterol
Answer: Uncontrolled hypertension
Rationale: Hypertension weakens vessel walls, increasing the risk of cerebral
hemorrhage.
10. What is the primary treatment goal for status epilepticus?
A. Lower blood pressure
B. Stop seizure activity
C. Increase glucose levels
D. Reduce fever
Answer: Stop seizure activity
Rationale: Status epilepticus requires immediate administration of anticonvulsants to
halt seizures and prevent brain damage.
Musculoskeletal Disorders (Week 9)
11. What is the pathophysiological mechanism of osteoarthritis?
A. Autoimmune destruction of synovial tissue
B. Degeneration of articular cartilage
C. Bone marrow suppression
D. Muscle atrophy
