,Q1. A patient with chronic kidney disease develops systemic edema. Which
mechanism is primarily responsible for this fluid shift?
A. Increased capillary hydrostatic pressure due to sodium retention
B. Decreased plasma oncotic pressure due to albuminuria
C. Increased capillary permeability due to inflammation
D. Lymphatic obstruction due to metastatic calcification
Correct Answer: B. Decreased plasma oncotic pressure due to albuminuria
Rationale: In chronic kidney disease, nephrotic-range proteinuria leads to
hypoalbuminemia and decreased plasma oncotic pressure, favoring fluid movement from
capillaries into the interstitium. Sodium retention can contribute to edema but is not the
primary mechanism; increased hydrostatic pressure is more typical of heart failure.
Increased capillary permeability is seen in inflammation, and lymphatic obstruction is a
localized cause.
Why Wrong:
A - Increased hydrostatic pressure is characteristic of heart failure, not primarily of
renal disease.
C - Increased permeability is seen in inflammatory states, not typically in chronic
kidney disease without concurrent inflammation.
D - Lymphatic obstruction is a localized cause (e.g., infection, tumor) and not
systemic in kidney disease.

Q2. In which cellular adaptation does a cell decrease its size and metabolic activity in
response to decreased workload, ultimately reducing oxygen consumption?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: A. Atrophy
Rationale: Atrophy is a decrease in cell size due to reduced workload, loss of innervation,
or inadequate blood supply. It reduces metabolic demands and oxygen consumption.
Hypertrophy is an increase in cell size, hyperplasia an increase in cell number, and
metaplasia is a reversible change from one mature cell type to another.
Why Wrong:
B - Hypertrophy increases cell size and workload, not decrease.
C - Hyperplasia increases cell number, not size, and is often due to increased demand.
D - Metaplasia is a change in cell type, not size or activity level.

for Disease in Adults and Children, 9th Ed., Ch. 3.
Q3. A researcher discovers a new cytokine that promotes chemotaxis of neutrophils to
sites of acute inflammation. This cytokine most likely belongs to which class of
inflammatory mediators?
A. Chemokines
B. Interleukins with pyrogenic activity
C. Prostaglandins
D. Leukotrienes
Correct Answer: A. Chemokines
Rationale: Chemokines are a family of small cytokines that specifically induce chemotaxis
of leukocytes, particularly neutrophils, to sites of inflammation. Interleukins with
pyrogenic activity (e.g., IL-1, IL-6) cause fever. Prostaglandins and leukotrienes are lipid
mediators that cause vasodilation, pain, and bronchoconstriction but not direct
chemotaxis.
Why Wrong:
B - Pyrogenic interleukins induce fever, not chemotaxis.
C - Prostaglandins primarily cause vasodilation and pain, not chemotaxis.
D - Leukotrienes are involved in smooth muscle contraction and vascular
permeability, not chemotaxis.
Reference: McCance, K.L. & Huether, S.E. (2026). Pathophysiology: The Biologic Basis
for Disease in Adults and Children, 9th Ed., Ch. 6.
Q4. A patient with sepsis develops high fever. Which endogenous pyrogen directly
acts on the hypothalamus to increase the thermoregulatory set point?
A. Interleukin-1
B. Tumor necrosis factor-alpha
C. Prostaglandin E2
D. Interferon-gamma
Correct Answer: C. Prostaglandin E2
Rationale: Endogenous pyrogens such as IL-1 and TNF-± induce fever by stimulating the
synthesis of prostaglandin E2 in the hypothalamus, which then raises the set point.
Prostaglandin E2 is the direct mediator on the thermoregulatory center. IL-1 and TNF- act
upstream, and interferon-gamma is not a primary pyrogen.
Why Wrong:
A - IL-1 is an endogenous pyrogen but works indirectly via prostaglandin synthesis.
B - TNF- also acts indirectly; it is a pyrogen but not the direct mediator on the
hypothalamus.
