Questions and Answers Practice Questions With Solutions
and Rationales Newest 2026-2027 | Already Graded A+
A patient experiences swelling, redness, heat, and pain after a tissue injury. Which process is
primarily responsible?
A. Cellular necrosis
B. Acute inflammation
C. Autoimmune destruction
D. Fibrosis
Rationale: Acute inflammation causes vasodilation and increased permeability leading to
classic signs of inflammation.
Which cell is primarily responsible for antibody production?
A. T lymphocyte
B. Macrophage
C. B lymphocyte
D. Neutrophil
Rationale: B cells differentiate into plasma cells that produce antibodies.
A patient with type 1 diabetes has hyperglycemia due to:
A. Insulin resistance
B. Excess glucagon secretion
C. Autoimmune destruction of beta cells
D. Pancreatic tumor
Rationale: Type 1 DM is caused by autoimmune beta-cell destruction.
Which electrolyte imbalance is most associated with cardiac arrhythmias?
A. Hypernatremia
B. Hypocalcemia
C. Hyperkalemia
D. Hypermagnesemia
Rationale: Potassium imbalance directly affects cardiac conduction.
A patient with asthma has bronchoconstriction due to:
A. Alveolar collapse
,2|Page
B. Airway inflammation and hyperresponsiveness
C. Pulmonary fibrosis
D. Pleural effusion
Rationale: Asthma is characterized by reversible airway obstruction.
Which condition is characterized by demyelination in the CNS?
A. Parkinson disease
B. Alzheimer disease
C. Multiple sclerosis
D. Myasthenia gravis
Rationale: MS involves immune-mediated destruction of myelin.
Fever is primarily mediated by:
A. Histamine
B. Bradykinin
C. Prostaglandins in hypothalamus
D. Dopamine
Rationale: Pyrogens stimulate prostaglandin release affecting thermoregulation.
Shock is defined as:
A. Hypertension with organ damage
B. Inadequate tissue perfusion
C. Fluid overload
D. Increased cardiac output
Rationale: Shock results in insufficient oxygen delivery.
Which lab finding indicates kidney dysfunction?
A. Low creatinine
B. Low BUN
C. Elevated creatinine
D. Low potassium
Rationale: Creatinine increases with reduced renal filtration.
Atherosclerosis is primarily caused by:
A. Viral infection
B. Lipid accumulation and inflammation in arterial walls
C. Autoimmune attack
D. Hypoxia only
Rationale: Plaque formation involves lipids and inflammatory response.
Which hormone increases blood glucose levels?
A. Insulin
, 3|Page
B. Glucagon
C. Calcitonin
D. Aldosterone
Rationale: Glucagon stimulates glycogen breakdown.
COPD is most commonly caused by:
A. Allergens
B. Genetic mutation
C. Smoking and chronic irritant exposure
D. Viral infection
Rationale: Long-term exposure damages airways.
Which is a hallmark of malignant tumors?
A. Encapsulation
B. Metastasis
C. Slow growth
D. Well-differentiated cells
Rationale: Cancer spreads to distant sites.
Anemia causes fatigue primarily due to:
A. Increased oxygen delivery
B. Reduced oxygen-carrying capacity
C. Increased hemoglobin
D. Fluid overload
Rationale: Low RBCs reduce oxygen transport.
Which immune response is immediate and nonspecific?
A. Adaptive immunity
B. Innate immunity
C. Humoral immunity
D. Passive immunity
Rationale: Innate immunity responds rapidly without specificity.
Myocardial infarction results from:
A. Valve failure
B. Coronary artery blockage
C. Hypertension only
D. Aortic dilation
Rationale: Occlusion causes ischemia of heart tissue.
Edema occurs due to:
A. Decreased hydrostatic pressure
