NR507 MIDTERM ADVANCED PATHOPHYSIOLOGY EXAM
WITH COMPLETE QUESTIONS AND CORRECT DETAILED
SOLUTIONS ALL WITH RATIONALED LATEST THIS YEAR
NR507 Midterm Exam Coverage Summary
The NR507 Advanced Pathophysiology midterm exam at Chamberlain University covers Weeks
1–4 content, focusing on foundational pathophysiological mechanisms across key body systems.
Topics include cellular injury and adaptation, inflammation and immune responses (including
hypersensitivity reactions), hematological disorders (anemias, coagulopathies), cardiovascular
pathologies (heart failure, hypertension, atherosclerosis), pulmonary disorders (COPD, asthma,
restrictive lung diseases), and urinary system pathologies (acute kidney injury, chronic kidney
disease, glomerulonephritis). The exam consists of 100–200 multiple-choice questions testing
clinical application, disease mechanisms, and diagnostic reasoning.
NR507 Midterm Exam (Advanced Pathophysiology)
Randomized MCQs with Summarized Rationales
1. A patient presents with fatigue, pallor, and shortness of breath on exertion. Laboratory
findings show hemoglobin 8.2 g/dL, mean corpuscular volume (MCV) 72 fL, and serum ferritin 8
ng/mL. What is the most likely diagnosis?
A) Vitamin B12 deficiency anemia
B) Anemia of chronic disease
C) Iron deficiency anemia
, Page 2 of 111
D) Thalassemia minor
Correct answer: C
*Low MCV (microcytic) with low ferritin indicates iron deficiency anemia; B12 deficiency causes
macrocytic anemia; thalassemia presents with normal/high ferritin.*
2. Which type of hypersensitivity reaction is mediated by IgE antibodies and involves mast cell
degranulation?
A) Type I
B) Type II
C) Type III
D) Type IV
Correct answer: A
Type I hypersensitivity is IgE-mediated, causing immediate allergic reactions such as
anaphylaxis, urticaria, and asthma via mast cell degranulation.
3. A 60-year-old with a history of hypertension presents with sudden onset of severe chest pain
radiating to the back. Blood pressure is 100/60 mmHg in the right arm and 80/50 mmHg in the
left arm. Which condition is most likely?
A) Acute myocardial infarction
, Page 3 of 111
B) Pulmonary embolism
C) Aortic dissection
D) Pericarditis
Correct answer: C
Asymmetric blood pressures and tearing chest pain radiating to the back are classic for aortic
dissection; unequal pulses reflect differential branch vessel involvement.
4. In heart failure with reduced ejection fraction (HFrEF), which compensatory mechanism
initially increases cardiac output but eventually leads to maladaptive ventricular remodeling?
A) Natriuretic peptide release
B) Parasympathetic activation
C) Renin-angiotensin-aldosterone system (RAAS) activation
D) Bradycardia
Correct answer: C
RAAS activation initially increases preload and contractility via angiotensin II and aldosterone,
but chronic activation causes fibrosis, hypertrophy, and worsening failure.
5. A patient with COPD has an FEV1/FVC ratio of 0.65. This finding indicates:
A) Restrictive lung disease
, Page 4 of 111
B) Obstructive lung disease
C) Normal lung function
D) Mixed obstructive-restrictive pattern
Correct answer: B
*FEV1/FVC <0.70 defines obstructive lung disease (COPD, asthma), as airway obstruction
reduces forced expiratory volume disproportionately.*
6. Which white blood cell is the "first responder" of the innate immune system, arriving within
hours of an inflammatory stimulus?
A) Lymphocytes
B) Eosinophils
C) Neutrophils
D) Basophils
Correct answer: C
Neutrophils are the first leukocytes to migrate to sites of infection or injury, initiating
phagocytosis and releasing inflammatory mediators.
7. A child presents with a barking cough, stridor, and suprasternal retractions. What is the most
likely diagnosis?
