A client who was diagnosed with heart failure has developed cardiogenic shock as a complication of the condition and needs an intra-aortic balloon pump placed. Which of the following statements accurately describes an intra-aortic balloon?
a. The IABP increases systemic vascular resistance to strengthen the heart's ventricles
b. The balloon is regularly inflated and deflated to support the pumping action of the heart
c. The catheter is typically inserted in the subclavian artery and inflated in the abdominal aortic artery
d. The balloon inflates during systole to increase pressure in the aorta
b. The balloon is regularly inflated and deflated to support the pumping action of the heart
rationale: An intra-aortic balloon pump (IABP) may be used for some clients in cardiogenic shock or in other situations where cardiac complications have developed. The IABP is designed to support the circulatory system when it is inserted into a vessel through the femoral artery and the balloon is positioned in the aorta. The balloon regularly inflates and deflates to support the work of the heart, which can increase ejection fraction, cardiac output and coronary perfusion.
