Applied Pathophysiology A Conceptual Approach, 4th Edition
Comprehensive Study Guide — 199 Questions & Answers
1. What is the primary function of the nucleus within a eukaryotic cell?
Answer: It contains the genetic code (DNA) essential for cell function and survival.
2. Which cellular adaptation involves a decrease in cell size due to disuse or insufficient blood supply?
Answer: Atrophy
3. What process describes the programmed, regulated cell death that removes worn-out or damaged cells?
Answer: Apoptosis
4. What are the classic local cardinal signs of acute inflammation?
Answer: Redness, heat, swelling, pain, and loss of function.
5. Which white blood cells are typically the first responders to arrive at an acute site of tissue injury?
Answer: Neutrophils
6. What type of immunity is provided by resident flora competing with disease-producing microorganisms?
Answer: Natural (innate) protective immunity
7. Why are yeast infections common in patients taking broad-spectrum antibiotics?
Answer: Destroying resident bacterial flora removes competing microbes, allowing fungi to overproliferate.
8. Which immunoglobulin class is primarily associated with allergic reactions and parasitic infections?
Answer: IgE
9. What term describes a stable, long-lasting viral infection where the virus integrates into host DNA without
immediate replication?
Answer: Latency
10. What genetic inheritance pattern requires two abnormal copies of a gene for the disease phenotype to
manifest?
Answer: Autosomal recessive
11. What compensatory mechanism handles metabolic acidosis in the body?
Answer: Hyperventilation to blow off carbon dioxide (CO2)
12. What primary electrolyte imbalance characterizes dehydration or water deficit?
Answer: Hypernatremia (high serum sodium)
13. Which neurotransmitter is predominantly deficient in the brains of individuals with Parkinson's disease?
Answer: Dopamine
14. What term describes a localized injury to the skin and underlying tissue usually over a bony prominence
due to pressure?
Answer: Pressure ulcer (decubitus ulcer)
15. What type of pain arises from direct injury to peripheral or central nervous system tissues?
Answer: Neuropathic pain
16. What underlying pathology causes atherosclerosis?
Answer: Chronic endothelial injury followed by lipid accumulation and plaque formation.
, 17. Which heart chamber experiences the greatest workload and hypertrophy in systemic hypertension?
Answer: Left ventricle
18. What pathophysiological change characterizes chronic bronchitis?
Answer: Hypertrophy of mucous glands and excessive mucus production in the airways.
19. What defines anemia in clinical parameters?
Answer: A reduction in the total circulating red blood cell mass or hemoglobin concentration.
20. What clotting factor deficiency is responsible for Hemophilia A?
Answer: Factor VIII deficiency
21. What biochemical hallmark distinguishes Type 1 Diabetes Mellitus from Type 2?
Answer: Absolute autoimmune destruction of pancreatic beta cells leading to a lack of insulin.
22. What hormone deficiency causes Diabetes Insipidus?
Answer: Antidiuretic hormone (ADH) or insensitivity of renal tubules to ADH.
23. What primary functional unit of the kidney is damaged in glomerulonephritis?
Answer: The glomerulus
24. What bacterium is most commonly implicated in the development of peptic ulcer disease?
Answer: Helicobacter pylori
25. What hormonal abnormality defines Polycystic Ovary Syndrome (PCOS)?
Answer: Hyperandrogenism and insulin resistance
26. What is the initial event in the pathogenesis of atherosclerosis?
Answer: Endothelial injury resulting from factors like dyslipidemia, hypertension, or smoking.
27. Which form of angina occurs unpredictably at rest and is often caused by coronary artery vasospasm?
Answer: Prinzmetal (variant) angina
28. What electrical abnormality on an electrocardiogram (ECG) typically indicates acute transmural
myocardial infarction?
Answer: ST-segment elevation
29. In left-sided heart failure, what primary clinical manifestation occurs due to pulmonary venous
congestion?
Answer: Dyspnea, orthopnea, and crackles in the lungs.
30. What compensatory neurohormonal system is chronically activated in heart failure, leading to sodium
and water retention and vasoconstriction?
Answer: The Renin-Angiotensin-Aldosterone System (RAAS)
31. Which type of shock is characterized by severe systemic vasodilation and maldistribution of blood flow,
commonly triggered by a severe allergic reaction?
Answer: Anaphylactic shock
32. What valvular heart disorder is classically preceded by a Group A beta-hemolytic streptococcal infection?
Answer: Rheumatic heart disease
33. What is the primary difference between a thrombus and an embolus?
Answer: A thrombus is a stationary blood clot attached to a vessel wall, whereas an embolus is a detached clot or
substance traveling through the bloodstream.
