The nurse is caring for a patient following insertion of an intraaortic balloon pump (IABP)for cardiogenic shock unresponsive to pharmacotherapy.Which hemodynamic parameter best indicates an appropriate response to therapy?
A) Cardiac index (CI) of 2.5 L/min/m²
B) Pulmonary artery diastolic pressure of 26 mm Hg
C) Pulmonary artery occlusion pressure (PAOP) of 22 mm Hg
D) Systemic vascular resistance (SVR) of 1600 dynes/sec/cm-5

Desired outcomes for a patient in cardiogenic shock with an IABP include decreased SVR,diminished symptoms of myocardial ischemia (chest pain,ST-segment elevation),increased stroke volume,and increased cardiac output and cardiac index.A cardiac index of 2.5 L/min is within normal limits.All other values are high and would not indicate an appropriate response to therapy.
