exam COMPLETE (2026) EXAM Questions and Answers (Verified
Answers) (Latest Update 2026) Graded A+
✅ MULTIPLE CHOICE QUESTIONS
1. Which leukocyte is MOST responsible for fighting bacterial infections?
A. Eosinophils
B. Basophils
C. Neutrophils
D. Lymphocytes
Rationale: Neutrophils are the primary phagocytes responding to bacteria.
2. A patient with chronic inflammation will show elevated:
A. Albumin
B. CRP (C-reactive protein)
C. HDL
D. Platelets
Rationale: CRP rises during inflammation as part of the acute-phase response.
3. Which immunoglobulin is responsible for a TYPE I hypersensitivity reaction?
A. IgA
B. IgG
C. IgM
D. IgE

Rationale: IgE binds allergens → mast cell degranulation → anaphylaxis.

,4. A patient with pernicious anemia lacks intrinsic factor. Which nutrient cannot
be absorbed?
A. Iron
B. B6
C. B12
D. Folate
Rationale: B12 requires intrinsic factor for absorption in the ileum.
5. A hallmark of acute inflammation is:
A. Slow onset
B. Absence of neutrophils
C. Exudate formation
D. No pain
Rationale: Acute inflammation → fluid, proteins, and WBCs leave vessels.
6. A type II hypersensitivity reaction involves:
A. IgE and mast cells
B. Immune complexes
C. T-cell mediated destruction
D. IgG/IgM targeting cells
Rationale: Type II = antibodies bind cell-surface antigens (e.g., transfusion rxn).
7. Which blood disorder is characterized by excessive RBC destruction?
A. Iron-deficiency anemia
B. Aplastic anemia
C. Hemolytic anemia
D. Sickle cell trait
Rationale: Hemolytic anemia = premature RBC destruction.

, A. Low RBC
B. Low platelets
C. Low WBC
D. High neutrophils
Rationale: WBC count falls below normal.
9. The primary cause of edema in inflammation is:
A. Vasoconstriction
B. Increased capillary permeability
C. Rapid lymphatic drainage
D. Decreased hydrostatic pressure
Rationale: Fluid moves out of vessels due to permeability ↑.
10. A characteristic of septic shock is:
A. Hypertension
B. Cool skin
C. Widespread vasodilation
D. Bradycardia
Rationale: Inflammatory mediators cause massive vasodilation → hypotension.
11. Which is a sign of iron-deficiency anemia?
A. Ruddy skin
B. Smooth, swollen tongue (glossitis)
C. Enlarged lymph nodes
D. Bone pain
Rationale: Iron deficiency → glossitis + spoon nails.
12. A patient with leukemia MOST likely presents with:
A. Hypercoagulation
B. Increased WBC but dysfunctional
C. Bradycardia
3
D. Elevated RBC count
Page
Rationale: Leukemia = many abnormal WBCs that don’t fight infection.
