NURS 6501 Actual Final Exam Version
2025 – Advanced Pathophysiology |
Complete Verified Answers | Grade A
Question 1
Which of the following is the primary mechanism of cellular injury in hypoxia?
A. Increased oxidative phosphorylation
B. Decreased ATP production
C. Enhanced calcium influx
D. Excessive protein synthesis
Rationale: Hypoxia leads to decreased ATP production due to impaired oxidative
phosphorylation in mitochondria, causing cellular dysfunction. Other options are secondary or
unrelated, per Walden NURS 6501 standards.
Question 2
A patient with type 1 diabetes presents with Kussmaul respirations. What is the underlying
pathophysiology?
A. Respiratory alkalosis from hyperventilation
B. Metabolic acidosis from ketone accumulation
C. Metabolic alkalosis from bicarbonate loss
D. Respiratory acidosis from hypoventilation
Rationale: Kussmaul respirations compensate for metabolic acidosis in diabetic ketoacidosis
(DKA) due to ketone buildup, per NURS 6501 standards.
Question 3
What is the hallmark feature of apoptosis?
A. Cellular swelling
B. Programmed cell death
C. Membrane rupture
D. Inflammatory response
, 2
Rationale: Apoptosis is a controlled, programmed cell death process without inflammation,
unlike necrosis, per NURS 6501.
Question 4
Which cytokine is primarily responsible for the systemic inflammatory response in sepsis?
A. IL-10
B. TNF-alpha
C. IL-4
D. IL-12
Rationale: TNF-alpha drives the systemic inflammatory response in sepsis, causing
vasodilation and organ dysfunction, per NURS 6501 standards.
Question 5
A patient with chronic hypertension develops left ventricular hypertrophy. What is the
underlying cellular change?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Rationale: Chronic hypertension increases cardiac workload, leading to hypertrophy (increased
cell size) of the left ventricle, per NURS 6501.
Question 6
Which condition is most associated with microangiopathic hemolytic anemia?
A. Iron deficiency anemia
B. Thrombotic thrombocytopenic purpura
C. Sickle cell anemia
D. Vitamin B12 deficiency
Rationale: Thrombotic thrombocytopenic purpura causes microangiopathic hemolytic
anemia due to red blood cell shearing in microvasculature, per NURS 6501.

Question 7
What is the primary cause of edema in nephrotic syndrome?
A. Increased hydrostatic pressure
B. Decreased oncotic pressure
C. Increased vascular permeability
D. Lymphatic obstruction
Rationale: Nephrotic syndrome causes protein loss, reducing oncotic pressure and leading to
edema, per NURS 6501 standards.
Question 8
A patient with a history of smoking presents with dyspnea and barrel chest. What is the likely
diagnosis?
A. Asthma
B. Chronic obstructive pulmonary disease
C. Pulmonary edema
D. Pneumothorax
Rationale: Smoking, dyspnea, and barrel chest are classic for COPD, characterized by airflow
obstruction, per NURS 6501.
Question 9
Which of the following is a key feature of Alzheimer’s disease pathology?
A. Lewy bodies
B. Amyloid plaques
C. Pick bodies
D. Neuroglial scars
Rationale: Amyloid plaques are a hallmark of Alzheimer’s disease, contributing to neuronal
damage, per NURS 6501.
Question 10
What is the primary pathophysiological mechanism of anaphylaxis?
A. T-cell mediated cytotoxicity
