NR 507 MIDTERM EXAM – ADVANCED PATHOPHYSIOLOGY | CHAMBERLAIN QUESTIONS AND
ANSWERS ALREADY GRADED A+| 100% VERIFIED SOLUTIONS………...
CORE DOMAINS
1. Cellular Adaptation, Injury, and Genetics
2. Fluid, Electrolyte, and Acid-Base Balance
3. Immunity, Inflammation, and Infection
4. Cardiovascular and Respiratory Pathophysiology
5. Renal, Endocrine, and Gastrointestinal Pathophysiology
6. Neurological and Musculoskeletal Pathophysiology
7. Hematology and Oncology Principles
8. Professional Application, Ethics, and Clinical Decision-Making
INTRODUCTION
This comprehensive midterm examination assesses advanced pathophysiological concepts across
major body systems. It evaluates foundational theory, applied professional knowledge, regulatory
and legal awareness, ethics, and clinical decision-making. The multiple-choice and scenario-based
structure emphasizes real-world application, critical thinking, and safe practice. Learners must
analyze mechanisms of disease, interpret clinical findings, and select the most defensible
pathophysiological explanation. The examination prepares candidates for advanced practice
assessment and professional certification readiness.
SECTION ONE: QUESTIONS 1–100
1. Which cellular adaptation involves an increase in cell size?
,A. Hyperplasia
🟢 B. Hypertrophy
C. Atrophy
D. Metaplasia
🔴 RATIONALE: Hypertrophy is an increase in the size of existing cells, often in response to
increased workload or hormonal stimulation.
2. A patient has pH 7.30, PaCO2 48 mm Hg, and HCO3 24 mEq/L. Which acid-base disorder is
present?
A. Metabolic acidosis
B. Metabolic alkalosis
🟢 C. Respiratory acidosis
D. Respiratory alkalosis
🔴 RATIONALE: Low pH with elevated PaCO2 indicates respiratory acidosis; a normal HCO3
suggests no renal compensation has occurred yet.
3. Which immunoglobulin crosses the placenta and provides fetal passive immunity?
🟢 A. IgG
B. IgA
C. IgM
D. IgE
,🔴 RATIONALE: IgG is the only immunoglobulin that crosses the placenta, providing passive
immunity to the fetus and newborn.
4. Which cell is the first responder during acute inflammation?
A. Macrophage
B. Lymphocyte
C. Eosinophil
🟢 D. Neutrophil
🔴 RATIONALE: Neutrophils are the first leukocytes to arrive at the site of acute inflammation
and are primary phagocytes.
5. Which hormone increases blood glucose by promoting gluconeogenesis?
A. Insulin
🟢 B. Cortisol
C. Calcitonin
D. Aldosterone
🔴 RATIONALE: Cortisol stimulates gluconeogenesis and increases blood glucose, especially
during stress.
6. Which electrolyte is the major intracellular cation?
A. Sodium
B. Calcium
, 🟢 C. Potassium
D. Chloride
🔴 RATIONALE: Potassium is the predominant intracellular cation, essential for resting
membrane potential and cellular function.
7. Which feature best distinguishes apoptosis from necrosis?
A. It causes inflammation
B. It involves cell swelling
C. It is always pathologic
🟢 D. It is programmed and non-inflammatory
🔴 RATIONALE: Apoptosis is programmed cell death that does not trigger inflammation, unlike
necrosis.
8. Which condition commonly causes hypernatremia due to free water loss?
🟢 A. Diabetes insipidus
B. Syndrome of inappropriate antidiuretic hormone
C. Heart failure
D. Nephrotic syndrome
🔴 RATIONALE: Diabetes insipidus causes excessive renal free water loss, leading to
hypernatremia.
9. Which immunoglobulin is primarily responsible for type I hypersensitivity reactions?
