Correct Answer: A

Rationale: Bradycardia is not typically associated with a flail chest. Flail chest is characterized by paradoxical chest wall movement, respiratory distress, and hypoxia, but it does not usually cause bradycardia. The other options, such as cyanosis (bluish discoloration of the skin due to poor oxygenation), hypotension (low blood pressure), and dyspnea (difficulty breathing), are commonly seen in patients with flail chest due to the underlying respiratory compromise.

Correct Answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.

Correct Answer: A

Rationale: Vecuronium is a neuromuscular blocking agent used for muscle relaxation during mechanical ventilation. When administering vecuronium, it is common to also give an opioid analgesic, such as fentanyl, to manage pain and ensure the patient's comfort. Fentanyl is often used in combination with neuromuscular blocking agents to provide balanced anesthesia, making it the appropriate medication to anticipate administering in this scenario.

Correct Answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

Correct Answer: D

Rationale: The correct answer demonstrates an understanding of the proper technique for using an incentive spirometer. Incentive spirometry helps to improve lung function by encouraging deep breathing and sustaining the inhalation to fully expand the lungs. Options A, B, and C are incorrect because they do not reflect the correct instructions for using an incentive spirometer.
