The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?
a. Arterial lactate level of 1.0 mEq/L
b. Cardiac output of 2.5 L/min
c. Mixed venous (SvO2 ) of 40%
d. Cardiac index of 1.5 L/min/m2
A
An arterial lactate level of 1.0 mEq/L is within normal limits and is indicative of normal oxygen delivery to the tissues. The cardiac output, mixed venous saturation, and cardiac index values are all below normal limits indicating inadequate cardiac output sufficient to provide oxygen delivery to the organs and tissues.
