Which data best supports the hypothesis of Acute respiratory distress requiring Urgency?

• A. Hypertension; BP 150/90
• B. Inactivity; fractured left ankle
• C. SaO2 89%, dyspnea
• D. Urinary Tract Infection; persistent urge to urinate

Answer: (C)

Acute respiratory distress requiring urgent action is best indicated by clear signs of impaired gas exchange, especially hypoxemia with active breathing difficulty. An oxygen saturation of 89% shows the blood isn’t being adequately oxygenated, which, when paired with dyspnea, signals true respiratory compromise needing rapid assessment and intervention. The other data don’t directly reflect respiratory failure: high blood pressure alone isn’t a marker of urgent respiratory distress, a fractured ankle with inactivity is a musculoskeletal issue, and a urinary tract infection involves the urinary system, not the lungs. In practice, low SpO2 with dyspnea points you toward urgent respiratory evaluation and treatment.
