,1. Which process best describes homeostasis?
A. Permanent physiologic change
B. Maintenance of internal balance
C. Disease progression
D. Genetic mutation
Correct Answer: B. Maintenance of internal balance
Rationale: Homeostasis refers to the body's ability to maintain
a stable internal environment despite external changes.
Regulatory mechanisms involving the nervous and endocrine
systems help preserve physiologic balance.
2. Which cellular adaptation is characterized by an increase
in cell size?
A. Hyperplasia
B. Metaplasia
C. Atrophy
D. Hypertrophy
Correct Answer: D. Hypertrophy
Rationale: Hypertrophy occurs when existing cells enlarge,
resulting in increased tissue or organ size. Skeletal muscle
enlargement after exercise is a common example.
3. Apoptosis is best defined as:
A. Uncontrolled cell death
B. Programmed cell death
, C. Cellular swelling
D. Tissue necrosis
Correct Answer: B. Programmed cell death
Rationale: Apoptosis is a regulated process that eliminates
damaged or unnecessary cells without triggering significant
inflammation.
4. Which electrolyte is the primary intracellular cation?
A. Sodium
B. Chloride
C. Potassium
D. Calcium
Correct Answer: C. Potassium
Rationale: Potassium is the major intracellular cation and
plays an essential role in nerve conduction, muscle
contraction, and cellular function.
5. Which acid-base imbalance is associated with prolonged
vomiting?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic alkalosis
D. Metabolic acidosis
