, I. FOUNDATIONS OF DISEASE, INFECTION & CELLULAR INJURY
1. What is the final stage of the infectious process?
Answer: Spread. A pathogen generally progresses through entry, invasion, multiplication, and spread from the initial site to other
tissues or hosts.
Exam focus: EXAM TRAP: Colonization means organisms are present but does not necessarily mean tissue invasion or disease.
2. What is the difference between colonization and infection?
Answer: Colonization is the presence and growth of microorganisms without tissue invasion or a host response causing disease.
Infection involves invasion and multiplication with a host response that may produce symptoms and tissue injury.
3. What is pathogenicity?
Answer: The capacity of a microorganism to cause disease. Virulence refers to the degree of pathogenicity or severity of disease
caused by a particular organism or strain.
4. What is the most common site for aspirated foreign bodies to lodge?
Answer: The right main bronchus is classically favored because it is wider, shorter, and more vertical than the left. Clinical details vary
with patient age and body position, but this is the high-yield anatomic principle.
5. What is the primary cause of neonatal respiratory distress syndrome?
Answer: Surfactant deficiency due to immature type II alveolar cells. Low surfactant increases alveolar surface tension, promoting
alveolar collapse and reducing lung compliance.
Exam focus: MEMORY: Surfactant = 'stay open.' Too little surfactant → alveoli collapse.
6. What is the difference between reversible and irreversible cell injury?
Answer: Reversible injury can resolve if the insult is removed before critical damage occurs. Irreversible injury involves severe
membrane dysfunction, mitochondrial failure, calcium dysregulation, or nuclear damage that culminates in cell death.
7. What is apoptosis?
Answer: A regulated, energy-dependent form of programmed cell death that usually affects individual cells and produces limited
inflammation because cellular contents remain contained in membrane-bound fragments.
8. What is necrosis?
Answer: Uncontrolled cell death caused by severe injury, with membrane disruption and leakage of cellular contents that commonly
triggers inflammation.
9. What is coagulative necrosis?
Answer: A pattern in which tissue architecture is initially preserved despite cell death. It is classically associated with ischemic injury in
solid organs except the brain.
10. What is liquefactive necrosis?
Answer: Enzymatic digestion transforms dead tissue into a liquid or viscous mass. It is characteristic of brain infarction and can occur in
abscesses.
11. What is caseous necrosis?
Answer: A cheese-like form of necrosis classically associated with granulomatous inflammation, such as tuberculosis.
12. What is fat necrosis?
Answer: Destruction of adipose tissue, often involving lipase release and saponification of fatty acids with calcium. It can occur in acute
pancreatitis.
