#1
Which of the following is a common cause of cardiogenic shock?
Myocardial infarction
ExplanationCaused by decreased cardiac function due to myocardial damage.
#2
Which of the following is a characteristic feature of cardiogenic shock?
Decreased cardiac output
ExplanationResulting from impaired heart function, leading to reduced blood flow.
#3
What is the hallmark symptom of cardiogenic shock?
Hypotension
ExplanationA key indicator of inadequate perfusion and cardiovascular collapse.
#4
What is the primary goal of treatment in cardiogenic shock?
To increase cardiac output
ExplanationTo restore effective tissue perfusion by enhancing heart function.
#5
Which medication is commonly used in the management of cardiogenic shock to increase myocardial contractility?
Epinephrine
ExplanationActs as a positive inotrope to enhance heart contraction strength.
#6
Which hemodynamic parameter is often decreased in cardiogenic shock?
Systemic vascular resistance
ExplanationDiminished due to vasodilation, leading to reduced blood pressure.
#7
Which of the following echocardiographic findings is suggestive of cardiogenic shock?
Right ventricular dilation
ExplanationIndicates right-sided heart failure, common in cardiogenic shock.
#8
Which of the following laboratory findings is commonly seen in cardiogenic shock?
Elevated lactate levels
ExplanationResulting from tissue hypoperfusion and anaerobic metabolism.
#9
Which of the following is a potential complication of cardiogenic shock?
Cardiac tamponade
ExplanationMay occur due to acute heart failure, leading to pericardial effusion.
#10
In cardiogenic shock, what is the primary mechanism leading to tissue hypoperfusion?
Decreased cardiac output
ExplanationReduced blood ejected by the heart results in inadequate tissue perfusion.
