What documented assessment finding is suggestive of compromised respiratory function? (Select all that apply.)

A. Dyspnea Subjective sensation of difficulty breathing, a classic sign of respiratory compromise. B. Bluish tinge to fingers Peripheral cyanosis indicates decreased oxygenation and poor perfusion. C. Restlessness May be an early sign of hypoxia due to decreased oxygen to the brain. D. Cyanosis of the trunk Central cyanosis is a late and severe sign of hypoxemia. E. Tachypnea Increased respiratory rate is a compensatory mechanism for inadequate oxygenation or increased CO₂.
