Success Exam) Graded A+
1. Which cellular adaptation is characterized by an increase in cell
size without an increase in cell number?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Rationale: Hypertrophy occurs when cells enlarge in response to
increased workload or stimulation without increasing their number.
2. Apoptosis differs from necrosis because apoptosis:
A. Causes inflammation
B. Results from severe trauma only
C. Is a programmed, energy-dependent process
D. Always involves bacterial infection
Rationale: Apoptosis is controlled cell death requiring ATP and
generally does not trigger inflammation.
3. Which electrolyte abnormality is most likely to cause peaked T
waves on an ECG?
A. Hypokalemia
B. Hyperkalemia
,C. Hyponatremia
D. Hypercalcemia
Rationale: Elevated potassium levels alter cardiac conduction,
producing peaked T waves.
4. The primary mechanism responsible for edema in congestive
heart failure is:
A. Decreased capillary permeability
B. Increased hydrostatic pressure
C. Reduced plasma osmotic pressure
D. Lymphatic obstruction
Rationale: Heart failure raises venous pressure, increasing capillary
hydrostatic pressure and fluid movement into tissues.
5. Which cytokine is considered the major endogenous pyrogen?
A. IL-10
B. IL-4
C. IL-1
D. IL-13
Rationale: IL-1 stimulates the hypothalamus to increase body
temperature during infection.
6. Which acid-base imbalance is commonly associated with
prolonged vomiting?
A. Respiratory acidosis
B. Metabolic alkalosis
C. Respiratory alkalosis
D. Metabolic acidosis
, Rationale: Loss of gastric hydrochloric acid causes metabolic
alkalosis.
7. The hallmark of chronic inflammation is:
A. Neutrophil predominance
B. Mononuclear cell infiltration
C. Massive hemorrhage
D. Platelet aggregation
Rationale: Chronic inflammation features macrophages,
lymphocytes, and plasma cells.
8. Which type of necrosis is most characteristic of cerebral
infarction?
A. Caseous
B. Fat
C. Liquefactive
D. Fibrinoid
Rationale: Brain tissue undergoes enzymatic digestion resulting in
liquefactive necrosis.
9. The Frank-Starling mechanism describes:
A. Cardiac conduction
B. Increased stroke volume with increased preload
C. Coronary artery dilation
D. Myocardial ischemia
Rationale: Increased ventricular filling stretches myocardial fibers,
increasing contractile force.
