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

A. Muscle twitching: Muscle twitching, particularly around the face or extremities, can indicate early signs of oxygen toxicity. High concentrations of oxygen over prolonged periods can lead to neurological manifestations, including twitching, dizziness, and confusion. B. Facial flushing: Facial flushing is more commonly associated with fever, allergic reactions, or vasodilation, not specifically with oxygen toxicity. It is not a reliable indicator of oxygen-related complications. C. Periorbital edema: Swelling around the eyes is typically related to fluid retention, allergic reactions, or renal/cardiac issues, and is not a characteristic finding in oxygen toxicity. D. Metallic taste in mouth: A metallic taste in the mouth can occur with certain medications or metabolic disturbances, but it is not a typical symptom associated with oxygen toxicity.
