An intraaortic balloon pump (IABP) is being used for a patient who is in cardiogenic shock. Which assessment data indicate to the nurse that the goals of treatment with the IABP are being met?
a. Urine output of 25 mL/hr
b. Heart rate of 110 beats/minute
c. Cardiac output (CO) of 5 L/min
d. Stroke volume (SV) of 40 mL/beat
ANS: C
A CO of 5 L/min is normal and indicates that the IABP has been successful in treating the shock. The low SV signifies continued cardiogenic shock. The tachycardia and low urine output also suggest continued cardiogenic shock.
