NURS 611 EXAM PACKAGE DEAL 2026/2027
100 Original Exam-Style Questions with Immediate Answers & Rationales
Questions are written to reflect commonly reported NURS 611 advanced pathophysiology domains. They are study
questions, not leaked or reproduced proprietary exam items.
1. A 65-year-old patient with longstanding hypertension has thickening of the left
ventricular wall. Which cellular adaptation best explains this finding?
○ A. Atrophy
☑ B. Hypertrophy
○ C. Hyperplasia
○ D. Metaplasia
Correct Answer: B. Hypertrophy
Rationale: Cardiac myocytes enlarge in response to chronic pressure overload; this is hypertrophy.
2. A patient has a myocardial infarction caused by prolonged interruption of coronary
blood flow. Which process is the most likely cause of the initial cellular injury?
○ A. Hyperplasia
☑ B. Ischemia
○ C. Metaplasia
○ D. Atrophy
Correct Answer: B. Ischemia
Rationale: Reduced blood flow causes ischemia, limiting oxygen and nutrient delivery and initiating cellular
injury.
3. Which finding is most characteristic of irreversible cellular injury?
○ A. Cellular swelling
○ B. Fatty change
☑ C. Severe mitochondrial dysfunction with membrane damage
○ D. Mild ribosomal detachment
Correct Answer: C. Severe mitochondrial dysfunction with membrane damage
Rationale: Irreversible injury is associated with severe membrane and mitochondrial damage and inability to
restore normal function.
4. A smoker develops replacement of normal respiratory epithelium by a different
mature epithelial cell type. This change is called:
○ A. Dysplasia
☑ B. Metaplasia
○ C. Anaplasia
○ D. Neoplasia
Correct Answer: B. Metaplasia
Rationale: Metaplasia is a potentially reversible replacement of one differentiated cell type by another.

,5. Which process is best described as programmed, regulated cell death with minimal
inflammation?
○ A. Necrosis
☑ B. Apoptosis
○ C. Autolysis
○ D. Ischemia
Correct Answer: B. Apoptosis
Rationale: Apoptosis removes unwanted or damaged cells through a regulated process and usually does not
trigger substantial inflammation.
6. Which laboratory finding most strongly suggests hyperkalemia?
○ A. Prominent U waves
☑ B. Peaked T waves
○ C. Shortened QT interval
○ D. ST elevation in every lead
Correct Answer: B. Peaked T waves
Rationale: Hyperkalemia classically causes tall, peaked T waves and, when severe, progressive conduction
abnormalities.
7. A patient with prolonged vomiting develops metabolic alkalosis. Which
compensatory response is expected?
○ A. Increased respiratory rate
☑ B. Decreased ventilation
○ C. Increased bicarbonate excretion immediately
○ D. Increased fixed acid production
Correct Answer: B. Decreased ventilation
Rationale: Hypoventilation retains carbon dioxide, providing respiratory compensation for metabolic alkalosis.
8. A patient has diabetic ketoacidosis. Which acid-base pattern is expected?
○ A. Metabolic alkalosis with respiratory acidosis
○ B. Respiratory alkalosis with metabolic acidosis
☑ C. High-anion-gap metabolic acidosis
○ D. Normal-anion-gap alkalosis
Correct Answer: C. High-anion-gap metabolic acidosis
Rationale: Accumulation of ketoacids produces a high-anion-gap metabolic acidosis.

, 9. Which finding is most consistent with respiratory acidosis?
○ A. Low PaCO2
☑ B. High PaCO2
○ C. Low bicarbonate only
○ D. High pH
Correct Answer: B. High PaCO2
Rationale: Respiratory acidosis results from inadequate ventilation and carbon dioxide retention, increasing
PaCO2.
10. A patient with severe diarrhea has a low serum bicarbonate level. Which disorder is
most likely?
☑ A. Metabolic acidosis
○ B. Metabolic alkalosis
○ C. Respiratory acidosis
○ D. Respiratory alkalosis
Correct Answer: A. Metabolic acidosis
Rationale: Loss of bicarbonate-rich intestinal fluid commonly produces metabolic acidosis.
11. Which mechanism is primarily responsible for edema in severe hypoalbuminemia?
○ A. Increased plasma oncotic pressure
☑ B. Decreased plasma oncotic pressure
○ C. Increased intracellular sodium
○ D. Decreased capillary permeability
Correct Answer: B. Decreased plasma oncotic pressure
Rationale: Low albumin decreases plasma oncotic pressure, favoring movement of fluid from the vascular space
into tissues.
12. A patient develops generalized edema from heart failure. Which hemodynamic
change contributes directly?
○ A. Reduced capillary hydrostatic pressure
☑ B. Increased capillary hydrostatic pressure
○ C. Increased plasma albumin
○ D. Reduced venous pressure
Correct Answer: B. Increased capillary hydrostatic pressure
Rationale: Venous congestion raises capillary hydrostatic pressure and promotes fluid filtration into the
interstitial space.
