Which cellular adaptation occurs when an organ increases in size
because its individual cells become larger?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Atrophy
Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in the size of individual cells,
resulting in enlargement of the affected tissue or organ. It commonly
occurs in skeletal muscle following resistance training and in cardiac
muscle in response to chronic hypertension. Hyperplasia involves an
increase in cell number, metaplasia is the replacement of one mature
cell type with another, and atrophy is a reduction in cell size or tissue
mass.
A patient experiences prolonged oxygen deprivation that causes
irreversible cell injury. Which cellular event is most directly associated
with this process?
A. Increased ATP production
,B. Enhanced sodium-potassium pump activity
C. Permanent loss of cellular membrane integrity
D. Increased protein synthesis
Answer: C. Permanent loss of cellular membrane integrity
Rationale: Severe or prolonged ischemia can cause irreversible cellular
damage. As ATP production declines, ion pumps fail, cells swell, and
intracellular calcium increases. Damage to cellular membranes and
mitochondria eventually becomes irreversible, leading to cell death.
Increased ATP production and protein synthesis are inconsistent with
severe energy failure.
Which type of cell death is characterized by cell shrinkage, chromatin
condensation, and fragmentation into membrane-bound bodies?
A. Apoptosis
B. Coagulative necrosis
C. Liquefactive necrosis
D. Caseous necrosis
Answer: A. Apoptosis
Rationale: Apoptosis is programmed cell death that removes unwanted
or damaged cells in a controlled manner. The cell shrinks, its
chromatin condenses, and cellular fragments are packaged into
apoptotic bodies. This process usually produces minimal inflammation
because cellular contents remain contained. Necrosis, in contrast,
,generally involves membrane disruption and can trigger an
inflammatory response.
A patient develops redness, warmth, swelling, and pain around an
infected wound. Which mechanism primarily causes the swelling?
A. Reduced blood flow through the affected tissue
B. Decreased vascular permeability
C. Destruction of all local immune cells
D. Increased vascular permeability with fluid movement into the
tissues
Answer: D. Increased vascular permeability with fluid movement into
the tissues
Rationale: Inflammation increases vascular permeability, allowing
fluid and proteins to move from blood vessels into surrounding tissues.
This accumulation produces edema and swelling. Vasodilation
contributes to redness and warmth, while inflammatory mediators and
tissue pressure contribute to pain. These responses help deliver
immune cells and protective proteins to the injured area.
Which laboratory finding is most consistent with an acute bacterial
infection?
A. Decreased neutrophil production in every case
B. Increased neutrophil count
C. Increased red blood cell destruction as the defining feature
, D. Reduced inflammatory signaling
Answer: B. Increased neutrophil count
Rationale: Neutrophils are important early responders in acute
bacterial infections. The bone marrow often releases additional
neutrophils, producing neutrophilia. Some severe infections may
instead cause neutropenia if neutrophils are consumed faster than they
can be produced, so the finding must be interpreted alongside the
patient's symptoms and other laboratory results.
Which immune response is primarily responsible for producing
antibodies against a specific antigen?
A. Humoral immunity mediated by B lymphocytes
B. Innate immunity mediated exclusively by neutrophils
C. Cell-mediated immunity mediated exclusively by cytotoxic T cells
D. Mechanical protection provided by intact skin
Answer: A. Humoral immunity mediated by B lymphocytes
Rationale: B lymphocytes can differentiate into plasma cells that
secrete antibodies against specific antigens. These antibodies may
neutralize pathogens, promote their destruction, or mark them for
removal by other immune mechanisms. Cytotoxic T cells primarily
destroy infected or abnormal cells, while innate defenses provide rapid,
relatively nonspecific protection.
A patient develops anaphylaxis after exposure to a medication. Which
immunological mechanism most directly causes this reaction?
