Question: 1 / 400

Which type of shock is characterized by inadequate blood flow due to heart failure?

Cardiogenic shock

Cardiogenic shock is characterized by inadequate blood flow resulting from the heart's inability to pump effectively. This condition often arises after a significant cardiac event, such as a myocardial infarction, where the heart muscle is damaged and unable to maintain sufficient cardiac output. In cardiogenic shock, the heart's reduced function leads to diminished perfusion of vital organs, resulting in symptoms such as hypotension, altered mental status, and decreased urine output. It is crucial for trauma nurses to recognize the signs of cardiogenic shock and initiate appropriate interventions quickly to improve outcomes for the patient. The underlying mechanism revolves around heart failure, which is why this type of shock stands out when discussing inadequate blood flow stemming from cardiac dysfunction.
