Correct Answer: B

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.

Correct Answer: C

Rationale: The correct answer is C. When documenting assessment data in the narrative nursing notes, it is essential to include objective findings that are specific, clear, and descriptive. 'S1 murmur auscultated in supine position' provides a precise and objective assessment finding that can aid in accurately documenting the client's condition. Choices A, B, and D are more subjective statements that lack the specificity and clarity required for detailed documentation. 'Client appears anxious' and 'Client is resting quietly' are subjective observations, while 'Client's skin is warm and dry' is an objective finding but may not be as significant or relevant for comprehensive documentation as the auscultated murmur.
