A patient has been admitted to the critical care unit with the diagnosis of acute respiratory distress syndrome (ARDS)
Arterial blood gasses (ABGs) revealed an elevated pH and decreased PaCO2 . The patient is becoming fatigued, and the health care provider orders a repeat ABG. The nurse anticipates the following results
a. elevated pH and decreased PaCO2
b. elevated pH and elevated PaCO2
c. decreased pH and decreased PaCO2
d. decreased pH and elevated PaCO2
D
Arterial blood gas analysis reveals a low PaO2 despite increases in supplemental oxygen administration (refractory hypoxemia). Initially, the PaCO2 is low as a result of hyperventilation, but eventually the PaCO2 increases as the patient fatigues. The pH is high initially but decreases as respiratory acidosis develops.
