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: B

Rationale: Urine output of 50 mL in 4 hours indicates oliguria, which can be a sign of worsening renal function and requires immediate intervention. In acute renal failure, maintaining adequate urine output is crucial to prevent further kidney damage and manage fluid balance. A high blood pressure reading (Option A) is concerning but may not require immediate intervention in this scenario as it could be due to the history of hypertension. A heart rate of 100 beats per minute (Option C) is slightly elevated but may not be the most critical finding at this moment. Nausea and vomiting (Option D) are important to assess but are not as urgent as addressing oliguria in a client with acute renal failure.

Correct Answer: B

Rationale: Intermittent bubbling in the suction control chamber is the correct observation indicating effective functioning of the chest tube. This bubbling signifies that the suction system is working correctly and maintaining the desired negative pressure in the pleural space. Continuous bubbling in the water-seal chamber suggests an air leak, which is not a normal finding. No fluctuation (tidaling) in the water-seal chamber may indicate a blockage or lack of communication between the pleural space and the water-seal, which is not ideal. Drainage of clear, pale yellow fluid from the chest tube is a normal finding, but it does not specifically indicate the effectiveness of the chest tube function.

Correct Answer: D

Rationale: Seeing halos around lights is a symptom of digoxin toxicity, which should be reported to the healthcare provider.
