A nurse caring for a client with a pulmonary embolism expects to find which diagnostic result?
A) Patchy infiltrates on chest x-ray
B) Metabolic alkalosis on arterial blood gas
C) Elevated CO2 level found on end-tidal carbon dioxide monitor
D) Tachycardia and nonspecific T-wave changes on EKG
Answer: D
With pulmonary embolism, tachycardia and nonspecific T-wave changes occur on EKG. The client with a pulmonary embolism will likely have respiratory alkalosis from rapid breathing, not metabolic alkalosis. The end-tidal carbon dioxide monitor (EtCO2) will be decreased, not increased, due to rapid breathing.
