Introduction
This comprehensive midterm examination review is designed for
advanced nursing students enrolled in NSG 5140 Advanced
Pathophysiology. The exam assesses foundational and applied knowledge
of disease mechanisms across cellular, systemic, and organ-system levels.
Emphasis is placed on understanding pathophysiological processes,
clinical manifestations, compensatory mechanisms, and evidence-based
decision-making. The 100 multiple-choice questions are structured to
evaluate critical thinking, clinical reasoning, and the ability to apply
pathophysiological principles to real-world patient scenarios. Each
question is accompanied by a detailed rationale to reinforce learning and
clarify the underlying science. This review serves as an essential tool for
examination preparation and clinical practice integration.
,SECTION ONE: QUESTIONS 1–100
1. A patient with chronic anemia and fatigue is found to have
decreased erythropoietin production. Which organ is most likely
responsible for this deficiency?
A. Liver
B. Spleen
C. Kidney
D. Bone marrow
C. Kidney
RATIONALE: Erythropoietin (EPO) is primarily produced by the
peritubular interstitial fibroblasts in the kidney. In response to hypoxia,
the kidneys increase EPO synthesis to stimulate erythrocyte production
in the bone marrow. Liver produces EPO in fetal life but only minimally
in adults. Spleen and bone marrow are not primary sites of EPO
production.
2. A patient presents with severe metabolic acidosis secondary to
diabetic ketoacidosis. Which compensatory respiratory response
would the healthcare provider expect to observe?
A. Hypoventilation with increased PaCO₂
B. Hyperventilation with decreased PaCO₂
C. Normal respiratory rate and depth
D. Cheyne-Stokes respirations
B. Hyperventilation with decreased PaCO₂
RATIONALE: In metabolic acidosis, the body compensates by
increasing alveolar ventilation (Kussmaul respirations) to blow off
carbon dioxide, thereby decreasing PaCO₂ and partially correcting the
pH. Hypoventilation would worsen acidosis. Cheyne-Stokes respirations
,are associated with central nervous system disorders, not metabolic
acidosis.
3. Which cellular adaptation is characterized by a decrease in cell
size and metabolic activity in response to reduced workload or
nutrient supply?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
C. Atrophy
RATIONALE: Atrophy is the reduction in cell size and function due to
disuse, denervation, ischemia, malnutrition, or hormonal changes.
Hypertrophy is an increase in cell size; hyperplasia is an increase in cell
number; metaplasia is the replacement of one differentiated cell type
with another.
4. A patient with heart failure develops bilateral pitting edema and
jugular venous distention. Which pathophysiological mechanism is
primarily responsible for these findings?
A. Decreased capillary hydrostatic pressure
B. Increased plasma oncotic pressure
C. Increased capillary hydrostatic pressure
D. Decreased capillary permeability
C. Increased capillary hydrostatic pressure
RATIONALE: Heart failure leads to elevated venous pressure, which
increases capillary hydrostatic pressure. This forces fluid out of the
capillaries into the interstitial space, resulting in edema. Decreased
capillary hydrostatic pressure would reduce edema. Increased plasma
oncotic pressure and decreased capillary permeability would both favor
fluid retention within the vasculature.
, 5. A patient is diagnosed with a tumor that secretes growth factors
that bind to receptors on its own cell surface, promoting
autonomous proliferation. This phenomenon is known as:
A. Paracrine stimulation
B. Endocrine stimulation
C. Autocrine stimulation
D. Juxtacrine stimulation
C. Autocrine stimulation
RATIONALE: Autocrine stimulation occurs when a cell secretes
growth factors that bind to receptors on its own surface, creating a self-
sustaining proliferative loop. Paracrine stimulation involves signaling to
adjacent cells; endocrine involves distant targets via the bloodstream;
juxtacrine requires direct cell-to-cell contact.
6. A patient with a history of chronic obstructive pulmonary disease
(COPD) develops clubbing of the fingers. This finding is best
explained by:
A. Metaplastic changes in the nail bed epithelium
B. Hypertrophy of soft tissue due to chronic hypoxia
C. Necrosis of distal phalanges
D. Apoptosis of capillary beds
B. Hypertrophy of soft tissue due to chronic hypoxia
RATIONALE: Clubbing is an adaptive hypertrophic response of the
soft tissues of the nail beds to chronic hypoxia. It reflects increased
capillary density and connective tissue proliferation. It is not metaplasia,
necrosis, or apoptosis.
7. A patient with liver cirrhosis develops ascites. Which of the
following mechanisms contributes most directly to the formation of
ascitic fluid?
