QUESTIONS
Question 1:
Which of the following is a primary mechanism of cellular injury?
A) Apoptosis
B) Necrosis
C) Oxidative stress
D) All of the above
CORRECT OPTION: D) All of the above
RATIONALE: All three options (apoptosis, necrosis, and oxidative stress) can act as
mechanisms of cellular injury. Apoptosis and necrosis represent different pathways of cell death,
while oxidative stress can lead to cellular damage.
Question 2:
What is the primary pathophysiological mechanism in the development of atherosclerosis?
A) Inflammation
B) Endothelial dysfunction
C) Hyperlipidemia
D) Autoimmunity
CORRECT OPTION: B) Endothelial dysfunction
RATIONALE: Endothelial dysfunction is a critical initial event that leads to atherosclerosis,
allowing for the accumulation of lipids and inflammatory cells in the arterial walls.
Question 3:
In which condition is the role of insulin resistance most significant?
,A) Type 1 Diabetes
B) Type 2 Diabetes
C) Diabetic Ketoacidosis
D) Hyperglycemic Hyperosmolar State
CORRECT OPTION: B) Type 2 Diabetes
RATIONALE: Insulin resistance is the hallmark of Type 2 Diabetes, where the body's cells do
not respond effectively to insulin, leading to increased blood glucose levels.
Question 4:
Which of the following findings would most likely indicate an acute myocardial infarction?
A) Bradycardia
B) Elevated troponin levels
C) Normal EKG
D) Hypotension
CORRECT OPTION: B) Elevated troponin levels
RATIONALE: Elevated troponin levels are specific biomarkers for myocardial injury and are
utilized in the diagnosis of acute myocardial infarction.
Question 5:
Which of the following best describes ischemia?
A) Lack of oxygen
B) Lack of blood flow
C) Increased blood flow
D) Tissue necrosis
CORRECT OPTION: B) Lack of blood flow
RATIONALE: Ischemia refers to inadequate blood flow to a tissue, leading to a shortage of
oxygen and nutrients needed for cellular metabolism.
Question 6:
What is the leading cause of chronic kidney disease (CKD)?
A) Diabetes Mellitus
B) Hypertension
,C) Glomerulonephritis
D) Polycystic kidney disease
CORRECT OPTION: B) Hypertension
RATIONALE: Chronic hypertension is a significant risk factor for the development and
progression of chronic kidney disease.
Question 7:
During which phase of the cardiac cycle does the heart muscle relax?
A) Systole
B) Diastole
C) Contraction
D) Repolarization
CORRECT OPTION: B) Diastole
RATIONALE: Diastole is the phase when the heart muscle relaxes, allowing the chambers to
fill with blood.
Question 8:
What is the most common cause of acute liver failure?
A) Alcohol consumption
B) Hepatitis B
C) Autoimmune diseases
D) Acetaminophen overdose
CORRECT OPTION: D) Acetaminophen overdose
RATIONALE: Acetaminophen overdose is the leading cause of acute liver failure due to its
hepatotoxic effects.
Question 9:
Which of the following most accurately describes a stroke?
A) Cerebral ischemia
B) Cardiac ischemia
, C) Pulmonary embolism
D) Renal ischemia
CORRECT OPTION: A) Cerebral ischemia
RATIONALE: A stroke occurs when blood flow to the brain is interrupted (cerebral ischemia),
leading to brain tissue injury.
Question 10:
Which hormone is primarily responsible for regulating blood calcium levels?
A) Insulin
B) Glucagon
C) Calcitonin
D) Parathyroid hormone (PTH)
CORRECT OPTION: D) Parathyroid hormone (PTH)
RATIONALE: PTH is crucial for maintaining calcium homeostasis by increasing calcium
levels in the blood.
Question 11:
What is the primary cause of obstructive sleep apnea?
A) Anxiety
B) Upper airway obstruction
C) Heart failure
D) Central nervous system depression
CORRECT OPTION: B) Upper airway obstruction
RATIONALE: Obstructive sleep apnea is primarily caused by the physical blockage of the
upper airway during sleep.
Question 12:
Which condition is characterized by the presence of autoantibodies against cell-surface
receptors?
