A patient develops redness, warmth, swelling, and pain around a small
cut. Which physiological process is primarily responsible for the
redness and warmth?
A. Decreased blood flow caused by vasoconstriction
B. Increased blood flow caused by local vasodilation
C. Reduced capillary permeability
D. Decreased release of inflammatory mediators
Answer: B. Increased blood flow caused by local vasodilation
Rationale: Acute inflammation begins with the release of chemical
mediators, including histamine, which promote vasodilation. Increased
blood flow produces redness and warmth at the affected site. Increased
capillary permeability allows fluid and proteins to enter the tissues,
producing swelling, while inflammatory mediators and tissue pressure
contribute to pain.
Which type of immune cell is primarily responsible for producing
antibodies after differentiating into plasma cells?
A. Neutrophils
,B. Cytotoxic T lymphocytes
C. Natural killer cells
D. B lymphocytes
Answer: D. B lymphocytes
Rationale: B lymphocytes recognize specific antigens and can
differentiate into antibody-secreting plasma cells. Antibodies bind to
antigens, neutralize pathogens, promote phagocytosis, and activate
complement. Neutrophils primarily engulf microorganisms, whereas
cytotoxic T cells destroy infected or abnormal cells.
A patient develops a fever during a bacterial infection. Which
mechanism best explains the development of fever?
A. Pyrogens stimulate prostaglandin production in the hypothalamus,
raising the temperature set point.
B. Insulin release directly increases the hypothalamic temperature set
point.
C. Reduced metabolic activity causes the body to retain excessive heat.
D. Decreased hypothalamic activity causes uncontrolled sweating.
Answer: A. Pyrogens stimulate prostaglandin production in the
hypothalamus, raising the temperature set point.
Rationale: Endogenous pyrogens, including interleukin-1 and
interleukin-6, promote prostaglandin E2 production, which raises the
hypothalamic temperature set point. The body responds by conserving
and generating heat through vasoconstriction and shivering. When the
,set point returns to normal, sweating and vasodilation help lower body
temperature.
Which statement best describes the primary function of cytotoxic T
lymphocytes?
A. Producing immunoglobulin E
B. Releasing histamine during allergic reactions
C. Destroying infected or abnormal cells
D. Producing red blood cells in the bone marrow
Answer: C. Destroying infected or abnormal cells
Rationale: Cytotoxic T lymphocytes, also called CD8-positive T cells,
recognize antigens presented by major histocompatibility complex
class I molecules. They kill infected cells and certain cancer cells by
inducing apoptosis. Antibody production is primarily a B-cell function,
while histamine is released mainly by mast cells and basophils.
A patient with an autoimmune disease develops tissue damage because
the immune system attacks normal body structures. What is the
underlying problem?
A. Failure of the bone marrow to produce leukocytes
B. Loss of immune tolerance to self-antigens
C. Complete absence of inflammatory mediators
D. Inability to activate the complement system in any circumstance
Answer: B. Loss of immune tolerance to self-antigens
, Rationale: Autoimmune diseases develop when mechanisms that
normally prevent immune attacks against the body's own tissues fail.
Autoreactive lymphocytes or autoantibodies may damage specific
organs or multiple systems. The resulting inflammation can impair
organ function and produce chronic tissue injury.
Which laboratory finding is most consistent with iron-deficiency
anemia?
A. Increased mean corpuscular volume
B. Increased ferritin concentration
C. Elevated hemoglobin concentration
D. Reduced mean corpuscular volume
Answer: D. Reduced mean corpuscular volume
Rationale: Iron deficiency limits hemoglobin synthesis, causing red
blood cells to become smaller and often paler than normal. This
produces microcytic, hypochromic anemia. Ferritin is generally
reduced because it reflects iron stores, although ferritin may be
misleadingly normal or elevated when inflammation is present.
A patient experiences crushing chest pain due to an acute myocardial
infarction. Which process most directly causes myocardial cell injury?
A. Prolonged interruption of coronary blood flow leading to ischemia
and cellular death
B. Increased oxygen delivery to the myocardium
C. Temporary stimulation of the parasympathetic nervous system
