#1
Which of the following is a hallmark sign of septic shock?
Hypothermia
ExplanationDrop in body temperature due to systemic inflammation.
#2
What is the primary goal of treatment for shock?
Correct the underlying cause
ExplanationAddressing the root issue to restore normal physiology.
#3
Which of the following statements regarding shock is true?
Distributive shock is characterized by decreased vascular resistance
ExplanationBlood vessel dilation leads to reduced resistance to blood flow.
#4
Which of the following is a symptom of shock?
Tachypnea
ExplanationIncreased breathing rate to compensate for decreased oxygen delivery.
#5
What is the primary goal of fluid resuscitation in shock?
To restore normal blood pressure
ExplanationReplenishing lost fluids to improve circulation and blood pressure.
#6
Which of the following is a common cause of hypovolemic shock?
Severe burns
ExplanationFluid loss due to damaged skin barrier.
#7
Which of the following best describes the initial response in the compensatory stage of shock?
Increased heart rate and vasoconstriction
ExplanationEffort to maintain blood pressure and tissue perfusion.
#8
Which of the following is a key feature of cardiogenic shock?
Elevated central venous pressure
ExplanationIncreased pressure in the veins returning blood to the heart.
#9
Which of the following is a potential complication of shock?
Hyperkalemia
ExplanationElevated potassium levels due to cellular damage and dysfunction.
#10
Which of the following is a potential cause of obstructive shock?
Massive pulmonary embolism
ExplanationBlockage of blood flow in the pulmonary arteries.
#11
What is the role of lactate levels in assessing shock?
To evaluate tissue perfusion
ExplanationIndicator of oxygen debt and tissue oxygenation status.
#12
Which of the following is a common sign of shock in children?
Mottled skin
ExplanationPatchy skin discoloration due to poor circulation.
#13
Which of the following is a characteristic of distributive shock?
Peripheral vasodilation
ExplanationWidespread dilation of blood vessels leading to decreased vascular resistance.
#14
In neurogenic shock, what causes the loss of sympathetic tone?
Spinal cord injury
ExplanationDisruption of autonomic nervous system control due to spinal injury.
#15
What is the primary mechanism of action of vasopressors in treating shock?
Increase afterload
ExplanationEnhancing vascular resistance to elevate blood pressure.
#16
What is the main difference between septic shock and other forms of shock?
Septic shock results from an uncontrolled inflammatory response
ExplanationOverwhelming immune reaction causing widespread inflammation.
#17
Which of the following is a characteristic of the irreversible stage of shock?
Multiple organ failure
ExplanationSystemic dysfunction and failure of vital organs.
#18
What is the primary determinant of tissue perfusion in shock?
Cardiac output
ExplanationVolume of blood pumped by the heart per minute.
#19
How does septic shock differ from sepsis?
Septic shock is a more severe form of sepsis
ExplanationProgression to hypotension and organ dysfunction in septic shock.
