A nurse is reinforcing teaching with a newly licensed nurse about the manifestations of hypoxia. Which of the following findings should the nurse include in the teaching?

A. Warm, dry skin: Hypoxia more commonly causes cool, pale, or diaphoretic skin depending on sympathetic response and perfusion. B. Vomiting: Vomiting is not a typical direct sign of hypoxia. C. Tachycardia: The body increases heart rate to try to deliver more oxygen to tissues when arterial O₂ is low. D. Difficulty swallowing: Dysphagia is not a characteristic manifestation of hypoxia.
