PATHOPHYSIOLOGY FOUNDATIONS, CELLULAR INJURY & HOMEOSTASIS (Q1–Q10)
Q1. A 58-year-old patient with long-standing hypertension develops left ventricular
hypertrophy. Which pathophysiologic process best explains this adaptation?
A. Hyperplasia caused by increased cell number
B. Dysplasia resulting from chronic inflammation
,C. Hypertrophy caused by increased workload
D. Metaplasia due to tissue ischemia
Correct Answer: 🔴 C. Hypertrophy caused by increased workload
Explanation: 🔹 Cardiac muscle cells respond to chronic increased workload by enlarging
in size, a process known as hypertrophy. Because cardiac myocytes have limited ability to
divide, hyperplasia is not the primary mechanism. Dysplasia refers to abnormal cellular
development often associated with precancerous changes, while metaplasia involves
replacement of one mature cell type with another. Chronic hypertension increases
afterload, forcing the myocardium to enlarge to maintain cardiac output.
Q2. A nurse reviews laboratory findings for a patient with metabolic acidosis. Which
compensatory response would the nurse expect initially?
A. Decreased respiratory rate
B. Increased renal bicarbonate excretion
C. Hyperventilation to reduce carbon dioxide
D. Retention of hydrogen ions by the kidneys
Correct Answer: 🔴 C. Hyperventilation to reduce carbon dioxide
Explanation: 🔹 In metabolic acidosis, the body attempts to compensate rapidly through
the respiratory system. Hyperventilation lowers PaCO₂, thereby reducing acidity.
Decreased respiratory rate would worsen acidosis. The kidneys generally conserve
bicarbonate and excrete hydrogen ions rather than retain them. Respiratory
compensation occurs faster than renal compensation and is commonly observed as deep,
rapid breathing.
Q3. A patient with severe burns develops widespread capillary leakage and third-
spacing of fluids. Which mechanism primarily contributes to this phenomenon?
A. Increased plasma oncotic pressure
B. Reduced vascular permeability
C. Endothelial injury causing increased permeability
D. Excessive lymphatic drainage
,Correct Answer: 🔴 C. Endothelial injury causing increased permeability
Explanation: 🔹 Burn injuries damage vascular endothelial cells, increasing capillary
permeability and allowing fluid and proteins to leak into interstitial spaces. Increased
plasma oncotic pressure would draw fluid back into vessels rather than out. Reduced
permeability would limit leakage. Although lymphatic drainage may eventually become
overwhelmed, it is not the initiating mechanism behind third-spacing in burn patients.
Q4. A patient with chronic hypoxia secondary to COPD develops elevated hematocrit
levels. Which physiologic adaptation explains this finding?
A. Leukocytosis
B. Polycythemia
C. Thrombocytopenia
D. Hemodilution
Correct Answer: 🔴 B. Polycythemia
Explanation: 🔹 Chronic hypoxia stimulates erythropoietin release from the kidneys,
increasing red blood cell production and resulting in secondary polycythemia. This
adaptation improves oxygen-carrying capacity. Leukocytosis involves elevated white
blood cells, thrombocytopenia reflects low platelet count, and hemodilution would
reduce hematocrit rather than elevate it.
Q5. During sepsis, a patient develops multiple organ dysfunction syndrome (MODS).
Which pathophysiologic event is most responsible for this progression?
A. Localized inflammatory suppression
B. Excessive systemic inflammatory response
C. Decreased cytokine activity
D. Reduced endothelial activation
Correct Answer: 🔴 B. Excessive systemic inflammatory response
Explanation: 🔹 Sepsis triggers widespread inflammatory mediator release, endothelial
dysfunction, vasodilation, and microvascular thrombosis. This systemic inflammatory
, response damages organs and contributes to MODS. Cytokines are increased rather than
decreased. Localized suppression does not explain widespread organ failure, and
endothelial activation is enhanced during septic shock.
Q6. A patient with prolonged immobility develops muscle atrophy. Which cellular
adaptation best describes this change?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Correct Answer: 🔴 C. Atrophy
Explanation: 🔹 Atrophy refers to a reduction in cell size and tissue mass due to
decreased workload, loss of innervation, poor nutrition, or disuse. Immobility commonly
causes skeletal muscle atrophy. Hypertrophy is enlargement of cells, hyperplasia involves
increased cell numbers, and metaplasia involves replacement by another mature cell
type.
Q7. A patient with uncontrolled diabetes mellitus develops ketoacidosis. Which
primary mechanism contributes to ketone production?
A. Increased glucose utilization by cells
B. Excessive fat metabolism due to insulin deficiency
C. Enhanced glycogen storage in the liver
D. Reduced glucagon secretion
Correct Answer: 🔴 B. Excessive fat metabolism due to insulin deficiency
Explanation: 🔹 Insulin deficiency prevents glucose from entering cells efficiently, causing
the body to metabolize fats for energy. Fat breakdown produces ketones, leading to
metabolic acidosis. Glucose utilization is impaired, not increased. Glycogen storage
decreases, and glucagon secretion is usually elevated rather than reduced in diabetic
ketoacidosis.
