Exam 1 Focus: Fundamentals of pathophysiology, cell structures and
functions, fluid and electrolyte imbalances (e.g., typical signs of
dehydration, causes of hyponatremia), and acid-base balances
Q1. A patient with long-standing, untreated hypertension shows an increase in the
left ventricular muscle mass on an echocardiogram. The individual muscle cells have
grown larger but have not multiplied. Which cellular adaptation is this?
A. Hyperplasia
B. Metaplasia
🟢 C. Hypertrophy
D. Dysplasia
,Rationale: Hypertrophy is an increase in the size of individual cells, leading to an increase
in the size of the organ. It is a common response of cardiac and skeletal muscle to an
increased workload. Hyperplasia involves an increase in the number of cells.
Q2. A biopsy of the bronchial lining in a chronic cigarette smoker reveals that normal
ciliated columnar epithelial cells have been replaced by stratified squamous epithelial
cells. This represents which process?
🟢 A. Metaplasia
B. Anaplasia
C. Dysplasia
D. Atrophy
Rationale: Metaplasia is the reversible replacement of one mature cell type by another
mature cell type, often as an adaptation to chronic irritation or injury (like cigarette smoke).
While protective against friction, the new cells lose the original ciliary function.
Q3. During a routine Pap smear, a clinician notes abnormal, disordered cell growth
with variations in cell size, shape, and nuclear appearance. The pathology report
flags this as a precursor to neoplasia. What is the term for this?
A. Hypertrophy
🟢 B. Dysplasia
C. Metaplasia
D. Neoplasm
Rationale: Dysplasia refers to abnormal changes in the size, shape, and organization of
mature cells. It is frequently called "atypical hyperplasia" and is highly associated with
precancerous changes, though it can still be reversible if the stimulus is removed.
Q4. A patient experiences myocardial ischemia due to a blood clot blocking a
coronary artery. The lack of oxygen stops the mitochondrial electron transport chain,
causing a sharp drop in cellular ATP. What is the immediate direct consequence of
this ATP depletion within the cell?
A. The intracellular environment becomes highly alkaline.
B. The sodium-potassium pump overactivates, depleting glucose stores.
, 🟢 C. Sodium and water rush into the cell, causing cellular swelling.
D. Calcium ions are rapidly pumped out of the cytoplasm into the extracellular fluid.
Rationale: When ATP falls, the Na+/K+ ATPase pump fails. Sodium floods into the cell, and
water follows sodium osmotically, leading to acute cellular swelling (onchosis). Calcium also
floods into the cytoplasm, activating destructive enzymes.
Q5. A pathologist is examining tissue under a microscope and notes programmed,
orderly cell death where the cell shrinks, the chromatin condenses, and cellular
fragments break off into neat vesicles without causing an inflammatory response.
What is this process?
A. Coagulative necrosis
B. Liquefactive necrosis
🟢 C. Apoptosis
D. Caseous necrosis
Rationale: Apoptosis is programmed, energy-dependent cell death. Unlike necrosis, it is
highly regulated, affects scattered individual cells, keeps the cell membrane intact via
apoptotic bodies, and does not trigger an inflammatory response.
Q6. A patient presents with severe right lower quadrant abdominal pain. During an
emergency appendectomy, the surgeon removes an inflamed, ruptured appendix that
appears black, foul-smelling, and exhibits extensive bacterial invasion alongside
liquefactive and coagulative necrosis. What is the clinical term for this tissue state?
A. Dry gangrene
🟢 B. Wet gangrene
C. Fat necrosis
D. Fibrinoid necrosis
Rationale: Wet gangrene occurs when neutrophils invade the site, causing liquefactive
necrosis. It usually develops in internal organs, looks black, is foul-smelling due to bacterial
putrefaction, and spreads rapidly. Dry gangrene is typically sterile and limited to extremities.
Q7. A patient with severe end-stage liver failure has a serum albumin level of 1.8 g/dL
(Normal: 3.5–5.0 g/dL). The nurse notes massive ascites and 3+ pitting generalized
edema. Which fluid shift mechanism is driving this edema?
