ATI Detailed Answer Key Medical Surgical

Correct Answer: B

Rationale: When caring for a client with burns, especially burns to the face and chest, the priority action for the nurse is to inspect the mouth for signs of inhalation injuries. Inhalation injuries can be life-threatening and may not be immediately apparent. Identifying these injuries early allows for prompt intervention and can significantly impact the client's outcomes. While other actions such as pain management and blood tests are important, assessing for inhalation injuries takes precedence due to its critical nature.

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.

Correct Answer: B

Rationale: In myasthenia gravis, a neuromuscular disorder characterized by muscle weakness and fatigue, weakness is a common manifestation due to the immune system attacking the communication between nerves and muscles. Monitoring for weakness is crucial to assess the disease progression and determine the effectiveness of treatment. Confusion is not a typical manifestation of myasthenia gravis. Increased intracranial pressure and increased urinary output are not directly associated with this condition.

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: A

Rationale: In fat embolism syndrome (FES), fat globules enter the bloodstream and can lead to various complications, including a decrease in serum calcium levels. This occurs due to the formation of fat emboli in the vessels, which can interfere with calcium metabolism. Therefore, a decreased serum calcium level is an expected laboratory finding in a client with fat embolism syndrome.
