Subtopic 1: Overview and Classification of
Shock States
(20 Questions)
Question 1:
Which of the following best defines shock in the clinical context?
A. A sudden rise in systemic blood pressure
B. A state of inadequate tissue perfusion and oxygenation
C. An increase in intracranial pressure
D. A decrease in white blood cell count
Correct Answer: B
Rationale: Shock is fundamentally a state in which tissues do not receive
adequate oxygen and nutrients due to impaired perfusion. It can result from
multiple causes but always leads to cellular dysfunction and possible organ
failure.
Question 2:
Which type of shock is primarily caused by loss of intravascular volume?
A. Septic shock
B. Hypovolemic shock
C. Cardiogenic shock
D. Neurogenic shock
Correct Answer: B
, 3
Rationale: Hypovolemic shock results from fluid loss, whether due to
hemorrhage, burns, or dehydration, leading to decreased preload and cardiac
output.
Question 3:
What is the most common initial sign of shock in adults?
A. Decreased urine output
B. Altered mental status
C. Tachycardia
D. Low blood pressure
Correct Answer: C
Rationale: Tachycardia is often the first compensatory mechanism to
maintain cardiac output during early shock, preceding hypotension and other
symptoms.
Question 4:
Which of the following types of shock is characterized by vasodilation and
redistribution of blood flow?
A. Cardiogenic
B. Hypovolemic
C. Distributive
D. Obstructive
Correct Answer: C
Rationale: Distributive shock, including septic, neurogenic, and anaphylactic
shock, involves systemic vasodilation and blood pooling in the periphery.
Question 5:
, 4
Which of the following is NOT a category of shock?
A. Obstructive
B. Neuropathic
C. Cardiogenic
D. Distributive
Correct Answer: B
Rationale: Neuropathic is not a recognized category of shock. The main types
include hypovolemic, cardiogenic, distributive, and obstructive.
Question 6:
Which parameter best reflects cellular oxygenation in shock?
A. Serum creatinine
B. Capillary refill time
C. Blood pressure
D. Serum lactate levels
Correct Answer: D
Rationale: Elevated lactate levels indicate anaerobic metabolism, a sign of
tissue hypoxia often seen in shock.
Question 7:
What is a primary mechanism of cardiogenic shock?
A. Peripheral vasodilation
B. Hypovolemia
C. Impaired myocardial contractility
D. Spinal cord injury
