Define cardiogenic shock and one key nursing intervention.

The main idea being tested is recognizing cardiogenic shock as pump failure with hypoperfusion and knowing how to begin stabilization that addresses the low cardiac output. Cardiogenic shock occurs when the heart cannot pump effectively enough to meet the body's perfusion needs. Even if filling pressures are adequate, the forward flow remains insufficient, leading to signs of hypoperfusion such as cool, clammy skin, altered mental status, and reduced urine output. A key nursing priority is to support cardiac output quickly. Initiating inotropes helps improve contractility and cardiac output, while aggressive hemodynamic monitoring guides dosing and responses. Securing the airway is essential because respiratory status can deteriorate, and if the patient is having an acute myocardial infarction, preparing for rapid revascularization targets relief of the underlying cause and improves perfusion. This combination—low systolic blood pressure with hypoperfusion due to poor cardiac output, along with active measures to boost pump function and expedite definitive treatment—fits cardiogenic shock best. The other scenarios don’t fit cardiogenic shock. A high blood pressure with good perfusion isn’t shock. Shock can vary in presentation, but cardiogenic shock specifically centers on pump failure with signs of hypoperfusion despite adequate filling pressures. Hypotension due to dehydration points to hypovolemic shock, where aggressive fluids are the initial instinct, not inotropes or revascularization.
