Show Answers:

  1. Define etiology:
    The cause of a disease.
  2. What is the difference between a sign and a symptom?
    Sign: Physical observation or measurement (pulse, BP, temp)

    Symptoms: What the patient says or feels (pain, difficulty breathing)
  3. How is a diagnosis made?
    By determining the disease process by evaluating the manifestations. History, Physical exam & tests.
  4. What is palliative treatment?
    Treating symptoms only w/o affecting the outcome.
  5. Define inflammation:
    Response of living tissue to injury. Inflammatory process removes injured cells, debris & contains area of injury.

    • a) Physical injury to cell
    • b) Chemical agents
    • c) Allergies
  7. Describe the WBC’s found in inflammation. Which ones perform phagocytosis?
    Neutrophils, Eosinophils, Basophils.

    Neutrophils perform phagocytosis. (as well as monocytes)
  8. What are the 4 phases of the inflammatory process?
    • a) Histamine
    • b) Neutrophil exudation
    • c) Monocyte exudation
    • d) Repair/Restoration
  9. What are the ways in which the inflammatory process may end?
    • Tissue restoration w/scarring.
    • Abscess Formation.
    • Granuloma Formation.
  10. List the signs of inflammation:
    • Redness
    • Heat
    • Swelling/Edema
    • Pain
  11. How does chronic inflammation differ from acute?
    • Insidious & long lasting.
    • Exudation & repair occur together.
    • Less exudate & it has monocytes, lymphocytes, plasma & NO neutrophils.
  12. Describe treatments for inflammation:
    • Drugs (Anti-inflammatory drugs, Steroids, Antihistamines, Antimicrobials)
    • Rest & gradual exercise.
