ATI Detailed Answer Key Medical Surgical

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.

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: In a client with a sucking chest wound, the priority is to administer oxygen via nasal cannula to improve oxygenation. The client's blood pressure, weak pulse rate, and elevated respiratory rate indicate hypovolemic shock, so increasing oxygen supply is crucial. Raising the foot of the bed, removing the dressing, or preparing to insert a central line are not immediate actions needed for a client with a sucking chest wound and signs of shock.

Correct Answer: C

Rationale: An OSHA-approved N95 respirator mask is recommended when caring for a client with tuberculosis due to the airborne transmission of the disease. Tuberculosis poses a higher risk of transmission via respiratory droplets, making respiratory protection essential to prevent exposure and infection among healthcare workers.

Correct Answer: A

Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.
