Correct Answer: C

Rationale: Encouraging the use of an incentive spirometer is vital in preventing pulmonary complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, promoting lung expansion, and preventing atelectasis. Range-of-motion exercises help prevent musculoskeletal complications, while placing suction equipment at the bedside is important but not directly related to preventing pulmonary complications. Administering an expectorant may help with clearing secretions but is not as effective in preventing postoperative pulmonary complications as using an incentive spirometer.

Correct Answer: A

Rationale: Arterial blood gases are crucial to assess postoperatively in a client who has undergone thoracotomy and lobectomy to monitor oxygenation and ventilation status. Changes in arterial blood gases can indicate respiratory complications or inadequate gas exchange, which are critical issues that need prompt intervention to prevent further complications. While urinary output, chest tube drainage, and pain level are important assessments, monitoring arterial blood gases takes precedence in this specific postoperative scenario to ensure optimal respiratory function and overall patient well-being.

Correct Answer: D

Rationale: Gastroenteritis can lead to fluid loss through vomiting and diarrhea, especially when accompanied by fever. Fever can increase insensible water loss through sweating as well. Both vomiting and diarrhea can significantly contribute to fluid volume deficit, making the client with gastroenteritis and fever at higher risk compared to the other clients described in the options.

Correct Answer: C

Rationale: When the partner can independently perform the suctioning procedure, it demonstrates a readiness for the client's discharge. This indicates that the partner has acquired the necessary skills and knowledge to provide safe care for the client at home without the direct supervision of healthcare professionals.

Correct Answer: C

Rationale: Cheyne-Stokes respirations are characterized by periods of deep, rapid breathing followed by periods of apnea. This pattern is often seen in clients with neurological or cardiac conditions. Kussmaul respirations are deep and rapid breaths often associated with metabolic acidosis. Apneustic respirations are characterized by prolonged inhalations with shortened exhalations and can indicate damage to the pons. Stridor is a high-pitched, noisy respiratory sound usually associated with upper airway obstruction. Therefore, in this scenario, the client's alternating pattern of hyperventilation and apnea aligns with Cheyne-Stokes respirations.
