SECTION 1: FOUNDATIONAL PATHOPHYSIOLOGY
QUESTION 1
A patient presents with cellular swelling, fatty change, and accumulation of
substances in cells. What is the most likely cellular adaptation occurring?
A) Atrophy
B) Hypertrophy
C) Hyperplasia
D) Cellular injury
Correct ,,,,answer,,,,: D
Rationale: Cellular swelling, fatty change, and intracellular accumulation are
hallmarks of cellular injury, not adaptive changes. Atrophy is a decrease in cell
size, hypertrophy is an increase in cell size, and hyperplasia is an increase in cell
number .
,QUESTION 2
The nurse understands that necrosis is characterized by:
A) Programmed cell death without inflammation
B) Unregulated cell death with inflammation
C) Reversible cellular changes
D) Increased cellular function
Correct ,,,,answer,,,,: B
Rationale: Necrosis is unregulated, pathologic cell death that typically triggers an
inflammatory response. Apoptosis is programmed cell death without
inflammation .
QUESTION 3
A patient with prolonged ischemia to the heart muscle develops irreversible
cell death. This is best described as:
A) Apoptosis
B) Coagulative necrosis
C) Caseous necrosis
D) Liquefactive necrosis
Correct ,,,,answer,,,,: B
,Rationale: Coagulative necrosis is the most common type of necrosis and occurs
in solid organs like the heart following ischemia. The tissue maintains its
architecture but cells are dead .
QUESTION 4
Which statement best describes apoptosis?
A) Cell death caused by injury or trauma
B) Programmed cell death that eliminates damaged cells without inflammation
C) Cell death that always triggers an inflammatory response
D) Reversible cellular injury
Correct ,,,,answer,,,,: B
Rationale: Apoptosis is programmed cell death that occurs in response to normal
cellular turnover or damage. It eliminates cells without triggering inflammation .
QUESTION 5
A patient's lab results show hypoxia-induced changes. Which cellular process
is most likely impaired?
A) Protein synthesis
B) Aerobic metabolism and ATP production
C) DNA replication
D) Cell division
Correct ,,,,answer,,,,: B
, Rationale: Hypoxia impairs aerobic metabolism, leading to decreased ATP
production. Cells shift to anaerobic metabolism, which is less efficient and
produces lactic acid .
SECTION 2: FOUNDATIONAL PHARMACOLOGY
QUESTION 6
A drug with a high therapeutic index has:
A) A narrow margin of safety
B) A wide margin of safety
C) High risk of toxicity
D) Low efficacy
Correct ,,,,answer,,,,: B
Rationale: A high therapeutic index indicates a wide margin of safety, meaning
the drug is relatively safe. A low therapeutic index requires close monitoring .
QUESTION 7
A patient with liver cirrhosis is prescribed a medication that is extensively
metabolized by the liver. The nurse anticipates:
A) Increased drug clearance
B) Decreased drug clearance and increased risk of toxicity
