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. Agitation: Agitation is an early manifestation of hypoxia caused by insufficient oxygen delivery to the brain. It reflects central nervous system irritability and is often one of the first signs of low oxygen levels. B. Nausea: Nausea is not a primary or reliable indicator of hypoxia. While severe hypoxia can cause gastrointestinal symptoms indirectly, it is not a typical early manifestation. C. Warm, dry skin: Hypoxia often causes cool, pale, or cyanotic skin due to vasoconstriction and decreased oxygen delivery. Warm, dry skin is not associated with hypoxia. D. Dysphagia: Difficulty swallowing is not a characteristic sign of hypoxia. It is more related to neurological or structural disorders rather than oxygen deficiency.
