2026/2027 VERIFIED QUESTIONS & ANSWERS WITH DETAILED EXPERT
RATIONALE
1. Which of the following best describes the concept of homeostasis?
A. The process by which cells undergo apoptosis
B. The tendency of the body to maintain a stable internal environment
C. The mechanism of hormone secretion
D. The inflammatory response to tissue injury
E. The process of cellular differentiation
Correct Answer: B. The tendency of the body to maintain a stable internal
environment
EXPERT RATIONALE: Homeostasis refers to the dynamic equilibrium
maintained by the body's physiological processes to keep internal conditions
(temperature, pH, fluid balance) within a narrow, functional range despite external
changes.
,2. A patient presents with fever, redness, swelling, and pain at a wound site.
These findings are consistent with which process?
A. Neoplasia
B. Apoptosis
C. Atrophy
D. Acute inflammation
E. Chronic ischemia
Correct Answer: D. Acute inflammation
EXPERT RATIONALE: The cardinal signs of acute inflammation — heat (calor),
redness (rubor), swelling (tumor), and pain (dolor) — result from vasodilation,
increased vascular permeability, and leukocyte migration to the injured tissue.
3. Which cell type is the FIRST to arrive at a site of acute inflammation?
A. Macrophages
B. Lymphocytes
C. Eosinophils
D. Basophils
E. Neutrophils
Correct Answer: E. Neutrophils
EXPERT RATIONALE: Neutrophils are the first responders in acute
inflammation, arriving within minutes to hours via chemotaxis. They phagocytose
pathogens and release proteolytic enzymes to destroy invading organisms.
4. Which of the following describes cellular adaptation in response to
increased workload?
A. Atrophy
,B. Metaplasia
C. Hypertrophy
D. Dysplasia
E. Necrosis
Correct Answer: C. Hypertrophy
EXPERT RATIONALE: Hypertrophy is an increase in cell size in response to
increased demand or workload, such as cardiac muscle hypertrophy in response to
hypertension. It is an adaptive response to maintain function.
5. What type of necrosis is most commonly associated with myocardial
infarction?
A. Caseous necrosis
B. Liquefactive necrosis
C. Fat necrosis
D. Fibrinoid necrosis
E. Coagulative necrosis
Correct Answer: E. Coagulative necrosis
EXPERT RATIONALE: Coagulative necrosis occurs when ischemia causes protein
denaturation while preserving the cell outline. It is the hallmark of myocardial
infarction and most solid organ infarcts, except the brain.
6. Which of the following best describes apoptosis?
A. Uncontrolled cell death leading to inflammation
B. Programmed cell death that does not trigger inflammation
C. Cell death due to hypoxia
, D. Cell death due to toxic injury
E. Necrotic death of an organ
Correct Answer: B. Programmed cell death that does not trigger
inflammation
EXPERT RATIONALE: Apoptosis is a regulated, energy-dependent process of
programmed cell death. The cell shrinks, chromatin condenses, and apoptotic
bodies are formed and phagocytosed without triggering an inflammatory response,
unlike necrosis.
7. A patient has low oxygen delivery to tissues. Which term describes this
condition?
A. Hypercapnia
B. Hypoxemia
C. Hypoxia
D. Ischemia
E. Anoxia
Correct Answer: C. Hypoxia
EXPERT RATIONALE: Hypoxia refers to inadequate oxygen supply to tissues.
While hypoxemia refers specifically to low oxygen in blood, hypoxia is the broader
term for deficient oxygen at the tissue level, which can result from hypoxemia,
reduced blood flow, or impaired cellular oxygen use.
8. Which of the following is an example of liquefactive necrosis?
A. Myocardial infarction
B. Pulmonary tuberculosis
C. Brain infarction
