The nurse is caring for a client diagnosed with acute respiratory distress syndrome (ARDS). The client is intubated and placed on mechanical ventilation with positive pressure ventilation. Which assessment finding indicates a decrease of cardiac output secondary to positive pressure ventilation?
A)Blood pressure increases from 88/58 mmHg to 90/60 mmHg
B)Urine output decreases from 30 mL/hr to 25 mL/hr
C)Heart rate drops from 108 bpm to 104 bpm
D)Oxygen saturation increases from 82% to 90%

A)Reduced cardiac output results in reduced perfusion of the kidneys, with a resulting decrease in urine output. Expected urine output is at least 30 mL/hr. This client's urine output is decreased; therefore, this finding supports the diagnosis of decreased cardiac output. Although hypotension and tachycardia are indicative of a decreased cardiac output, both indicate improvement from the previous assessment, suggesting that they are not contributing to decreased cardiac output. The oxygen saturation level is within normal limits for this client and improving from the previous assessment.
