ATI Detailed Answer Key Medical Surgical

Correct Answer: A

Rationale: Preventing aspiration is the priority for a client with intermaxillary fixation following mandibular surgery. Aspiration can occur due to difficulty swallowing or improper positioning, posing a serious risk to the client's respiratory status. It is crucial for the nurse to ensure that the client's airway is clear and that they are positioned correctly to prevent any potential aspiration events.

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: 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: 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.
