Introduction: NSG3280 Exam 2 (2026) – Pathophysiology
for Nurses
Welcome to the NSG3280 Exam 2 Pathophysiology for Nurses review guide designed for
focused, high-yield exam preparation. This resource is built to help nursing students strengthen
their understanding of disease mechanisms, clinical reasoning, and physiological responses
commonly tested in advanced pathophysiology courses.
Pathophysiology is the foundation of nursing practice because it explains why diseases develop,
how they progress, and how the body responds to illness or injury. Mastery of these concepts
is essential for safe clinical decision-making, prioritization, and interpreting patient symptoms in
real-world settings.
This exam preparation set emphasizes:
Core disease processes across major body systems
Mechanisms of compensation and decompensation
High-yield clinical scenarios similar to exam questions
Application of concepts to nursing assessment and patient care
Step-by-step rationales to reinforce understanding, not memorization
The questions included are designed to reflect the style of graduate nursing exams, focusing on
critical thinking rather than simple recall. Each question challenges you to connect
underlying physiological changes with clinical presentation.
By working through this material, you will improve your ability to:
Recognize abnormal findings and link them to pathophysiology
Differentiate between similar disease processes
Anticipate complications based on disease progression
Strengthen exam readiness for NSG3280 Exam 2 (2026)
This guide is intended as both a study tool and a self-assessment resource, helping you build
confidence and accuracy before your exam.
,1. A patient presents with worsening shortness of breath and pulmonary crackles;
which pathophysiologic mechanism explains fluid accumulation in the lungs?
A. Decreased pulmonary pressure
B. Increased hydrostatic pressure in pulmonary capillaries causing fluid leakage into
alveoli
C. Increased oncotic pressure
D. Decreased venous return
Answer: B
Explanation: Increased pressure in pulmonary vessels forces fluid into alveoli, causing
edema.
2. A patient with chronic hypertension develops left ventricular hypertrophy; what is
the primary cause of this cardiac adaptation?
A. Decreased workload
B. Increased afterload requiring thicker ventricular muscle to pump effectively
C. Increased oxygen supply
D. Decreased resistance
Answer: B
Explanation: The heart thickens to overcome elevated systemic pressure.
3. A patient with type 2 diabetes mellitus develops hyperglycemia; what is the
primary mechanism responsible for elevated blood glucose levels?
A. Decreased insulin production
B. Peripheral insulin resistance reducing glucose uptake by cells
C. Increased insulin sensitivity
D. Increased glucose storage
,Answer: B
Explanation: Cells cannot respond properly to insulin.
4. A patient with COPD develops chronic carbon dioxide retention; what is the
underlying mechanism responsible for this abnormal gas exchange?
A. Increased ventilation
B. Alveolar hypoventilation and air trapping impairing carbon dioxide removal
C. Increased oxygen diffusion
D. Increased hemoglobin
Answer: B
Explanation: Air trapping prevents effective CO₂ elimination.
5. A patient with acute kidney injury caused by dehydration experiences decreased
urine output; what is the primary pathophysiologic cause?
A. Increased filtration
B. Reduced renal perfusion leading to decreased glomerular filtration rate
C. Increased sodium excretion
D. Increased fluid loss
Answer: B
Explanation: Reduced blood flow lowers kidney filtration.
6. A patient with metabolic acidosis demonstrates rapid breathing; what is the
physiologic purpose of this compensatory mechanism?
A. Increase oxygen
B. Eliminate carbon dioxide to raise blood pH toward normal levels
C. Retain carbon dioxide
D. Decrease bicarbonate
Answer: B
Explanation: Blowing off CO₂ reduces acidity.
, 7. A patient with anemia reports fatigue and weakness; what is the underlying
pathophysiologic cause of these symptoms?
A. Increased oxygen delivery
B. Reduced hemoglobin decreasing oxygen transport to tissues
C. Increased RBC production
D. Increased plasma volume
Answer: B
Explanation: Less oxygen reaches tissues.
8. A patient with sepsis develops hypotension; what is the primary mechanism
leading to decreased blood pressure in early septic shock?
A. Increased resistance
B. Systemic vasodilation due to inflammatory mediator release
C. Increased blood volume
D. Increased cardiac output
Answer: B
Explanation: Vessels dilate, lowering blood pressure.
9. A patient with hyperthyroidism experiences weight loss despite increased appetite;
what mechanism explains this finding?
A. Decreased metabolism
B. Increased metabolic rate leading to higher energy expenditure
C. Decreased oxygen use
D. Increased fat storage
Answer: B
Explanation: Energy is burned faster than intake.
