1. Which of the following is the most common cause of hypovolemic
shock?
a) Cardiac arrhythmias
b) Severe blood loss
c) Sepsis
d) Myocardial infarction
Answer: b) Severe blood loss
Rationale: Hypovolemic shock occurs when there is a significant loss of
blood volume, leading to inadequate tissue perfusion. The most
common cause is hemorrhage (severe blood loss), which reduces the
circulatory volume and impairs the delivery of oxygen to tissues.


2. Which of the following is the primary factor that leads to
vasodilation in septic shock?
a) Release of histamine
b) Increased sympathetic activity
c) Excessive production of nitric oxide
d) Low blood oxygen levels
Answer: c) Excessive production of nitric oxide
Rationale: In septic shock, bacterial toxins lead to the excessive release
of inflammatory mediators like nitric oxide, which causes vasodilation
and contributes to the decrease in blood pressure associated with
septic shock.


3. In acute pancreatitis, which of the following enzymes is primarily
responsible for pancreatic tissue damage?

,a) Amylase
b) Lipase
c) Trypsin
d) Chymotrypsin
Answer: c) Trypsin
Rationale: Trypsin is the primary proteolytic enzyme in the pancreas. In
acute pancreatitis, premature activation of trypsin leads to
autodigestion of pancreatic tissue, causing inflammation and injury.


4. Which of the following is a characteristic finding in the
pathophysiology of chronic obstructive pulmonary disease (COPD)?
a) Decreased lung compliance
b) Increased lung compliance
c) Decreased work of breathing
d) Decreased expiratory flow rate
Answer: b) Increased lung compliance
Rationale: In COPD, the airways become obstructed and the lungs lose
elastic recoil. This results in increased lung compliance, making it easier
to expand the lungs, but harder to expel air during exhalation. The
increased work of breathing and decreased expiratory flow rate are also
common features.


5. In diabetic ketoacidosis (DKA), which of the following contributes
most to the development of metabolic acidosis?
a) Increased production of ketone bodies
b) Decreased renal excretion of hydrogen ions

, c) Hyperkalemia
d) Elevated glucose levels
Answer: a) Increased production of ketone bodies
Rationale: In DKA, the body begins to break down fat as an energy
source due to lack of insulin, leading to the production of ketone bodies
(acetoacetate and beta-hydroxybutyrate). These are acidic, and their
accumulation causes metabolic acidosis.


6. Which of the following is the most significant contributor to the
development of atherosclerosis?
a) Hypercholesterolemia
b) Hyperglycemia
c) Hypertension
d) All of the above
Answer: d) All of the above
Rationale: Atherosclerosis is a complex process that involves the
accumulation of lipids (hypercholesterolemia), the thickening of the
arterial wall due to hypertension, and damage caused by high glucose
levels in diabetes (hyperglycemia). Each of these factors plays a
significant role in the development of atherosclerosis.


7. Which of the following is the primary cause of the clinical
manifestations of cirrhosis?
a) Portal hypertension
b) Increased bilirubin production
c) Decreased liver regeneration
d) Decreased clotting factor synthesis
