ATI Detailed Answer Key Medical Surgical

Correct Answer: D

Rationale: When a client's heart rate increases and becomes irregular during suctioning of an endotracheal tube, it indicates potential hypoxemia. Performing pre-oxygenation before suctioning helps prevent hypoxemia and subsequent dysrhythmias. This intervention ensures that the client has adequate oxygen reserves before the procedure, reducing the risk of complications related to suctioning.

Correct Answer: A

Rationale: When a client sustains burns to the head, neck, or chest, the risk of airway obstruction is a critical concern due to potential swelling, inflammation, or inhalation injury. Any compromise to the airway can lead to severe respiratory distress or failure. Early recognition and intervention to maintain a clear airway are essential to prevent life-threatening complications in burn patients.

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: B

Rationale: In clients with laryngeal cancer, hoarseness is often one of the earliest manifestations due to vocal cord involvement. The irritation and inflammation caused by the tumor affect the vocal cords, leading to changes in voice quality. Dysphagia (choice A) typically occurs later as the tumor grows and interferes with swallowing. Dyspnea (choice C) and weight loss (choice D) may occur as the cancer progresses, but hoarseness is usually among the first signs to manifest in laryngeal cancer.

Correct Answer: C

Rationale: Chronic bronchitis is often linked to smoking. Smoking cessation is the most effective preventive measure to reduce the risk of developing chronic bronchitis. Smoking damages the airways and leads to inflammation, making individuals more susceptible to chronic bronchitis. While maintaining an ideal weight, getting an annual influenza vaccine, and engaging in regular moderate exercise are beneficial for overall health, the most crucial intervention to prevent chronic bronchitis is quitting smoking.
