NURSING PATHOPHYSIOLOGY COMPREHENSIVE EXAM
PRACTICE QUESTIONS AND ANSWERS: THE MOST RECENT
AND COMPREHENSIVE VERSION WITH VERIFIED ANSWERS;
GUARANTEED PASS WITH INSTANT PDF DOWNLOAD.
Exam Overview
This examination assesses comprehensive knowledge of nursing pathophysiology aligned with
professional nursing curricula, licensing standards, and real-world clinical practice. The test
evaluates foundational mechanisms of disease, cellular adaptation, genetics, inflammation,
immunity, fluid and electrolyte balance, acid–base disorders, hematology, cardiovascular,
respiratory, renal, endocrine, gastrointestinal, neurological, musculoskeletal, reproductive,
integumentary, and multisystem disorders. Ethical, legal, and clinical decision-making principles
are integrated throughout.
1. A patient with chronic hypertension develops left ventricular hypertrophy.
This is best described as:
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Dysplasia
Hypertrophy is an increase in cell size due to increased workload. Cardiac muscle
responds to chronic pressure overload with hypertrophy.
2. During early inflammation, which mediator is primarily responsible for
vasodilation?
A. Complement
B. Histamine
C. Bradykinin
D. Interleukin-2
,Histamine released from mast cells causes immediate vasodilation and increased
vascular permeability.
3. A patient with vomiting for 3 days is most at risk for:
A. Metabolic acidosis
B. Respiratory alkalosis
C. Metabolic alkalosis
D. Respiratory acidosis
Loss of gastric acid (HCl) results in metabolic alkalosis.
4. Which cellular change is reversible?
A. Coagulative necrosis
B. Apoptosis
C. Liquefactive necrosis
D. Cellular swelling
Cellular swelling due to ATP depletion is reversible if oxygenation is restored.
5. Anaphylaxis is mediated primarily by:
A. IgG
B. IgM
C. IgE
D. IgA
Type I hypersensitivity reactions are mediated by IgE antibodies.
6. A low hemoglobin level reduces oxygen delivery because:
A. Cardiac output decreases
B. Blood viscosity increases
, C. Oxygen-carrying capacity decreases
D. Plasma volume expands
Hemoglobin binds oxygen; low levels reduce transport capacity.
7. In septic shock, hypotension occurs primarily due to:
A. Decreased heart rate
B. Myocardial infarction
C. Systemic vasodilation
D. Pulmonary embolism
Inflammatory mediators cause widespread vasodilation.
8. A potassium level of 6.5 mEq/L may result in:
A. Muscle spasms
B. Seizures
C. Cardiac arrhythmias
D. Tetany
Hyperkalemia affects cardiac conduction, leading to arrhythmias.
9. The most common cause of hypoxemia in pneumonia is:
A. Hypoventilation
B. Ventilation–perfusion mismatch
C. Low hemoglobin
D. Decreased cardiac output
Alveolar filling impairs gas exchange causing V/Q mismatch.
, 10.Which hormone lowers blood glucose?
A. Glucagon
B. Cortisol
C. Growth hormone
D. Insulin
Insulin promotes cellular uptake of glucose.
11.In heart failure, edema results from:
A. Decreased capillary pressure
B. Increased hydrostatic pressure
C. Decreased sodium retention
D. Low aldosterone
Venous congestion increases hydrostatic pressure causing fluid leakage.
12.Which acid–base imbalance is expected in COPD exacerbation?
A. Metabolic alkalosis
B. Respiratory acidosis
C. Metabolic acidosis
D. Respiratory alkalosis
CO₂ retention causes respiratory acidosis.
13.Iron deficiency anemia typically presents with:
A. Macrocytosis
B. Microcytic hypochromic cells
C. Leukocytosis
D. Polycythemia
