The nurse is caring for a patient in cardiogenic shock who is being treated with an intraaortic balloon pump (IABP). The family inquires about the primary reason for the device. What is the best statement by the nurse to explain the IABP?
a. "The action of the machine will improve blood supply to the damaged heart."
b. "The machine will beat for the damaged heart with every beat until it heals."
c. "The machine will help cleanse the blood of impurities that might damage the heart."
d. "The machine will remain in place until the patient is ready for a heart transplant."
A
The IABP improves coronary artery perfusion, reduces afterload, and improves perfusion to vital organs. An IABP acts through counterpulsation, augmenting the pumping action of the heart, displacing blood to improve both forward and backward blood flow. It does not "beat" for the damaged heart. An IABP does not filter blood impurities. An IABP is designed as a temporary therapy for use when pharmacological interventions alone are not effective. It is indicated for short-term use, not as a bridge to transplant.
