What is the primary B) Inadequate tissue perfusion
characteristic of shock?
A) Hypertension Rationale: Shock is defined by inadequate tissue
B) Inadequate tissue perfusion, leading to decreased oxygen and
perfusion nutrient delivery to cells.
C) Increased oxygen
delivery
D) Increased cardiac
output
Which of the following C) Lactic acid accumulation
best describes the
primary consequence of Rationale: Anaerobic metabolism results in lactic
anaerobic metabolism in acid accumulation, leading to metabolic acidosis
shock? and further impairing cellular function.
A) Increased ATP
production
B) Increased oxygen
consumption
C) Lactic acid
accumulation
D) Enhanced cellular
function
,What is the major cause C) Lactic acid accumulation
of metabolic acidosis in
shock? Rationale: Inadequate oxygen delivery forces cells
A) Hypoventilation into anaerobic metabolism, leading to lactic acid
B) Excessive bicarbonate accumulation and metabolic acidosis.
production
C) Lactic acid
accumulation
D) Hyperkalemia
Which type of shock is B) Hypovolemic shock
caused by reduced
blood volume? Rationale: Hypovolemic shock results from a
A) Cardiogenic shock significant decrease in blood volume, leading to
B) Hypovolemic shock inadequate perfusion.
C) Distributive shock
D) Neurogenic shock
Which type of shock is A) Cardiogenic shock
primarily caused by heart
failure? Rationale: Cardiogenic shock results from
A) Cardiogenic shock decreased cardiac output due to heart dysfunction,
B) Hypovolemic shock leading to poor tissue perfusion.
C) Septic shock
D) Neurogenic shock
What happens to sodium C) Sodium and water accumulate inside the cells
and water balance in
cells during shock? Rationale: ATP depletion leads to Na+/K+ pump
A) Sodium moves out of failure, causing sodium and water to accumulate
the cells inside cells, leading to cellular swelling.
B) Water moves out of
the cells
C) Sodium and water
accumulate inside the
cells
D) There is no change in
sodium and water
balance
, Why does tachycardia A) To compensate for decreased cardiac output
occur in shock?
A) To compensate for Rationale: The body increases heart rate to
decreased cardiac compensate for low cardiac output and maintain
output blood flow to vital organs.
B) To decrease oxygen
demand
C) To reduce metabolic
rate
D) To increase waste
removal
What is the major cause B) Impaired oxygen and nutrient delivery
of organ dysfunction in
shock? Rationale: Organ dysfunction results from
A) Increased blood inadequate oxygen and nutrient supply, leading to
pressure cellular injury and failure.
B) Impaired oxygen and
nutrient delivery
C) Enhanced cellular
metabolism
D) Excessive waste
removal
Which type of shock is C) Septic shock
most commonly
associated with systemic Rationale: Septic shock is caused by widespread
infections? infection, leading to vasodilation, increased capillary
A) Hypovolemic shock permeability, and decreased perfusion.
B) Cardiogenic shock
C) Septic shock
D) Neurogenic shock
Which metabolic process C) Oxidative phosphorylation
is most impaired during
shock? Rationale: Inadequate oxygen delivery impairs
A) Protein synthesis oxidative phosphorylation, leading to decreased
B) Glycolysis ATP production and reliance on anaerobic
C) Oxidative metabolism.
phosphorylation
D) Lipid metabolism
