A nurse is collecting data from a client who has asthma and displays manifestations of hypoxia. Which of the following findings should the nurse expect?

A. Bradycardia: Hypoxia typically triggers a sympathetic response with tachycardia, not bradycardia, except in very late/terminal events. B. Bradypnea: Hypoxia usually causes increased respiratory rate (tachypnea) as the body attempts to improve oxygenation. C. Pallor: Pallor may be seen with poor perfusion or anemia and can accompany hypoxia, but it is less specific than oxygenation signs. D. Cyanosis: Cyanosis (bluish discoloration of the skin or mucous membranes) is a reliable clinical indicator of significant hypoxemia and is an expected manifestation in advanced or severe hypoxia.
