Rationale: Impaired gas exchange is the highest priority nursing diagnosis because it directly impacts the client's oxygenation. Following coronary artery bypass graft surgery, ensuring adequate oxygen exchange is crucial for the client's recovery. Ineffective breathing pattern, although important, may not be as critical as impaired gas exchange in the immediate postoperative period. Acute pain, while significant, can be managed effectively with appropriate interventions and is not as emergent as addressing impaired gas exchange. Risk for infection is also a valid concern post-surgery, but ensuring optimal gas exchange takes precedence to prevent complications associated with inadequate oxygenation.
