A nurse is assessing a client who has oxygen toxicity. Which of the following findings should the nurse expect?

A. Metallic taste in the mouth:
This is not a typical finding of oxygen toxicity. Metallic taste may be associated with other factors but is not a specific indicator of oxygen toxicity.

B. Facial flushing:
Facial flushing is not a typical finding in oxygen toxicity. It is more commonly associated with other conditions, such as certain allergic reactions or vasodilation.

C. Muscle twitching

Muscle twitching, also known as myoclonus, is a recognized symptom of central nervous system oxygen toxicity. High concentrations of oxygen, particularly at increased pressures, can cause neurotoxic effects leading to muscle twitching, dizziness, and even convulsions.

D. Periorbital edema:
Periorbital edema is not a common manifestation of oxygen toxicity. It is more commonly associated with conditions related to fluid balance or kidney function.

A. Pneumothorax: A pneumothorax occurs when air accumulates in the pleural space, causing the lung to collapse. It often presents with unilateral chest pain, dyspnea, and diminished or absent breath sounds on the affected side.

B. Atelectasis: Atelectasis refers to the collapse of alveoli in the lungs, often caused by obstruction, compression, or lack of surfactant. Symptoms include hypoxemia, diminished breath sounds, and shortness of breath.

C. Hemothorax: A hemothorax occurs when blood accumulates in the pleural space. It typically presents with chest pain, dyspnea, and diminished or absent breath sounds on the affected side.

D. Flail Chest: Flail chest results from multiple rib fractures that create a free-floating segment of the chest wall. This condition causes paradoxical chest movement, where the chest wall segment moves inward during inspiration and outward during expiration.
