Introduction
This practice exam is designed to prepare advanced nursing students for the NURS 5315 Advanced
Pathophysiology Exam 1. The assessment evaluates critical knowledge of disease mechanisms at the cellular
and systemic levels, emphasizing the ability to apply pathophysiological concepts to clinical decision-making.
The test consists of 200 multiple-choice and scenario-based questions divided into two sections. Questions
range from foundational theory to complex real-world clinical scenarios, requiring critical thinking and
professional judgment. Mastery of this content ensures nurses can accurately interpret patient data,
anticipate disease progression, and implement evidence-based interventions grounded in deep
pathophysiological understanding.
,SECTION ONE: QUESTIONS 1–100
Question 1
A patient presents with cellular swelling and mitochondrial dysfunction following prolonged hypoxia. Which
reversible cellular change is most likely occurring?
A. Apoptosis
B. Hydropic degeneration
C. Necrosis
D. Karyorrhexis
🟢 Correct answer: B
🔴 RATIONALE: Hydropic degeneration (also called cellular swelling) is an early, reversible response to
cellular injury caused by failure of energy-dependent ion pumps (particularly Na+/K+), leading to intracellular
water accumulation. Apoptosis, necrosis, and karyorrhexis are irreversible forms of cell death or nuclear
breakdown.
Question 2
Which mechanism best explains the development of lactic acidosis in hypoxic tissues?
A. Increased oxidative phosphorylation
B. Shift to anaerobic metabolism
C. Enhanced glutathione reduction
D. Activation of caspase pathways
,🟢 Correct answer: B
🔴 RATIONALE: Under hypoxic conditions, cells shift from aerobic to anaerobic metabolism to generate ATP.
Anaerobic glycolysis produces lactate as a byproduct, leading to lactic acidosis. Oxidative phosphorylation
requires oxygen and is impaired in hypoxia.
Question 3
A 65-year-old patient with chronic alcoholism presents with hepatomegaly. Liver biopsy shows accumulation of
triglycerides within hepatic cytoplasm. This finding is best described as:
A. Necrosis
B. Steatosis
C. Metaplasia
D. Hypertrophy
🟢 Correct answer: B
🔴 RATIONALE: Steatosis (fatty change) is the abnormal accumulation of triglycerides within parenchymal
cells, commonly seen in alcohol-induced liver disease. Necrosis is cell death; metaplasia is reversible cell type
substitution; hypertrophy is increased cell size.
Question 4
Which of the following is a hallmark feature of irreversible cellular injury?
, A. Cellular swelling
B. Ribosomal detachment
C. Severe membrane damage
D. Increased glycolysis
🟢 Correct answer: C
🔴 RATIONALE: Severe, pervasive damage to plasma membranes, mitochondrial membranes, and lysosomal
membranes is the defining characteristic of irreversible injury leading to necrosis. Cellular swelling, ribosomal
detachment, and increased glycolysis are features of reversible injury.
Question 5
A patient with myocardial infarction has elevated serum creat kinase and LDH. Which type of cell death is most
characteristic of this ischemic event?
A. Apoptosis
B. Autophagy
C. Necrosis
D. Pyroptosis
🟢 Correct answer: C
🔴 RATIONALE: Ischemic injury from myocardial infarction typically causes coagulative necrosis, an
irreversible form of cell death marked by enzyme leakage (CK, LDH) into circulation. Apoptosis is programmed,
non-inflammatory cell death; autophagy is self-degradation for recycling.
