NURS 6501: Advanced Pathophysiology Graduate Comprehensive
Examination With Correct Answers Version 2026/2027
1. Which specific cellular process involves the programmable, highly regulated destruction of a
cell without causing a widespread inflammatory response in adjacent tissues?
Correct Answer: Apoptosis
2. What specific metabolic byproduct accumulates inside muscle cells during severe hypoxic
states when pyruvate is forced to undergo anaerobic glycolysis?
Correct Answer: Lactic acid
3. What type of adaptive cellular transformation involves the reversible replacement of one
mature somatic cell type by another, frequently seen in the respiratory lining of chronic
smokers?
Correct Answer: Metaplasia
4. What specific genetic term describes an error during cellular meiosis where homologous
chromosomes or sister chromatids completely fail to separate properly?
Correct Answer: Nondisjunction
5. Which specific chromosome abnormality is the genetic driver of Down syndrome?
Correct Answer: Trisomy 21
6. What genetic term describes the physical or outward clinical expression of a person's
underlying DNA sequence configuration?
Correct Answer: Phenotype
7. Which specific class of immunoglobulins is the most abundant in systemic circulation and
provides the majority of antibody-mediated protection against invading pathogens?
Correct Answer: Immunoglobulin G (IgG)
8. What specific type of immune hypersensitivity reaction is mediated by IgG or IgM antibodies
binding directly to fixed antigens on a target cell surface, such as in hemolytic transfusion
reactions?
Correct Answer: Type II hypersensitivity
9. What primary chemical mediator is released directly from the intracellular granules of mast
cells during an acute Type I hypersensitivity reaction to trigger rapid vasodilation?
Correct Answer: Histamine
10. What specific autoantibody is considered the primary diagnostic immunological marker for
systemic lupus erythematosus (SLE)?
Correct Answer: Antinuclear antibody (ANA)
11. What specific mechanical vector allows HIV to convert its single-stranded viral RNA directly
into double-stranded DNA inside a host helper T cell?
Correct Answer: Reverse transcriptase
12. What primary type of cell functions as the main structural driver of the innate, non-specific
immune system by performing rapid phagocytosis at an acute infection site?
Correct Answer: Neutrophil
, 13. What terminology describes the clinical condition of a patient whose total absolute
neutrophil count drops below 1,500 cells/µL, severely increasing their risk for systemic
infections?
Correct Answer: Neutropenia
14. What specific diagnostic cellular finding, characterized by a unique "owl-eye" microscopic
appearance, confirms a diagnosis of Hodgkin lymphoma?
Correct Answer: Reed-Sternberg cells
15. What severe, life-threatening clinical syndrome involves widespread, microvascular clotting
that simultaneously consumes all available platelets and coagulation factors, leading to
severe spontaneous bleeding?
Correct Answer: Disseminated intravascular coagulation (DIC)
16. What specific condition is caused by a profound deficiency of intrinsic factor secretion by the
gastric parietal cells, preventing the systemic absorption of Vitamin B12?
Correct Answer: Pernicious anemia
17. What specific form of anemia is characterized morphologically by the presence of microcytic,
hypochromic red blood cells on a peripheral blood smear?
Correct Answer: Iron deficiency anemia
18. What physical condition involves an abnormal, localized dilation or ballooning of an arterial
wall, commonly occurring in the abdominal aorta due to chronic atherosclerotic
degradation?
Correct Answer: Aneurysm
19. What primary underlying pathophysiological process drives the progressive development of
coronary artery disease, characterized by lipid deposition and plaque formation within the
arterial tunica intima?
Correct Answer: Atherosclerosis
20. What specific cardiac condition is characterized by a temporary, reversible imbalance
between myocardial oxygen supply and demand, presenting as chest pain that resolves
completely with rest?
Correct Answer: Stable angina
21. Which specific serum biomarker displays the highest clinical sensitivity and specificity for
confirming an acute myocardial infarction in an emergency setting?
Correct Answer: Cardiac troponin (I or T)
22. What specific type of cardiomyopathy is characterized by marked ventricular dilation,
thinned myocardial walls, and severely impaired systolic contraction?
Correct Answer: Dilated cardiomyopathy
23. What specific physiological metric calculates the percentage of blood pumped out of the left
ventricle with each single cardiac contraction, which drops below 40% in systolic heart
failure?
Correct Answer: Ejection fraction
24. What structural abnormality involves the incomplete or improper closure of the mitral valve
leaflets, causing blood to flow backward into the left atrium during ventricular systole?
Correct Answer: Mitral regurgitation
