Introduction
This midterm examination is designed for Chamberlain University nursing students enrolled in NR507 Advanced
Pathophysiology. It assesses the ability to integrate foundational pathophysiologic concepts with clinical
manifestations, diagnostic findings, and therapeutic principles. The 100 multiple-choice questions focus on high-
yield topics including hypersensitivity reactions, anemia, heart failure, valvular heart disease, and chronic
obstructive pulmonary disease, alongside related systems. Many items present realistic patient scenarios that
require interpretation of signs, symptoms, and laboratory data. Critical thinking, prioritization, and application of
evidence-based pathophysiology are essential for success. This exam prepares students for both the midterm
evaluation and the advanced clinical reasoning expected in professional nursing practice.
,SECTION ONE
Question 1
A patient with a history of seasonal allergies presents with sneezing, rhinorrhea, and itchy eyes minutes after
exposure to pollen. This reaction is mediated by:
A. IgM
B. IgE
C. IgG
D. IgA
🟢 Correct Answer:
B
🔴 RATIONALE:
Type I hypersensitivity (immediate) involves IgE bound to mast cells, triggering degranulation and release of
histamine and other mediators upon allergen re-exposure.
Question 2
Which type of anemia is characterized by macrocytic, megaloblastic red blood cells due to vitamin B12
deficiency?
A. Iron deficiency anemia
B. Aplastic anemia
C. Pernicious anemia
D. Sickle cell anemia
🟢 Correct Answer:
C
🔴 RATIONALE:
,Vitamin B12 deficiency leads to impaired DNA synthesis, causing large, immature erythrocytes (megaloblasts).
Pernicious anemia results from autoimmune destruction of gastric parietal cells or lack of intrinsic factor.
Question 3
A patient with left-sided heart failure is likely to exhibit which primary clinical manifestation?
A. Jugular venous distention
B. Ascites
C. Pulmonary congestion and dyspnea
D. Peripheral edema
🟢 Correct Answer:
C
🔴 RATIONALE:
Left ventricular failure causes increased pulmonary venous pressure, leading to fluid extravasation into alveoli,
producing dyspnea, orthopnea, and crackles. Right-sided failure primarily leads to systemic congestion.
Question 4
In aortic stenosis, the left ventricle responds to increased afterload by:
A. Decreasing wall thickness
B. Concentric hypertrophy
C. Dilatation without hypertrophy
D. Atrophy
🟢 Correct Answer:
B
🔴 RATIONALE:
, Pressure overload from aortic stenosis leads to parallel replication of sarcomeres, resulting in increased wall
thickness (concentric hypertrophy) to normalize wall stress.
Question 5
The primary pathophysiologic mechanism of chronic obstructive pulmonary disease (COPD) involves:
A. Reversible bronchoconstriction
B. Fixed airway obstruction due to inflammation and loss of elastic recoil
C. Pulmonary fibrosis
D. Alveolar hemorrhage
🟢 Correct Answer:
B
🔴 RATIONALE:
COPD is characterized by chronic inflammation in airways and lung parenchyma, leading to airway narrowing,
increased mucus, and destruction of alveolar walls (emphysema) with loss of elastic recoil, causing airflow
limitation that is not fully reversible.
Question 6
A patient receives a blood transfusion and develops fever, chills, and back pain. This is most likely a:
A. Type I hypersensitivity reaction
B. Type II (antibody-mediated) cytotoxic reaction
C. Type III immune complex reaction
D. Type IV delayed-type reaction
🟢 Correct Answer:
B
🔴 RATIONALE:
