Question

The clinical manifestations of cardiogenic shock reflect the pathophysiology of heart failure (HF). By applying this correlation, the nurse notes that the degree of shock is proportional to which of the following?

A. Left atrial function
B. Right ventricular function
C. Left ventricular function
D. Right atrial function

Answer 1

The degree of cardiogenic shock is most directly proportional to left ventricular function, given its crucial role in pumping oxygenated blood to the entire body.

Step-by-step explanation:

The clinical manifestations of cardiogenic shock are indeed reflective of the pathophysiology of heart failure (HF). The degree of shock is indicative of the heart's ability to pump effectively. After considering the roles of different heart chambers in circulation, it becomes clear that the majority of the cardiac output is attributable to the left ventricle, as it is responsible for pumping oxygenated blood to the systemic circulation. This means that the degree of cardiogenic shock correlates most directly with C. Left ventricular function.

When the left ventricle is compromised, as in cases of myocardial infarction or cardiomyopathy, its ability to generate sufficient force to propel the blood through the circulatory system is severely diminished. This results in poor systemic perfusion and leads to the systemic effects observed in cardiogenic shock. Hence, the assessment and maintenance of left ventricular function are critical in managing cardiogenic shock.
