Which finding indicates that the patient's condition is improving?

A. Temperature of 101.8°F: A temperature above 100.4°F indicates continued fever and inflammation, suggesting the infection is still active. A persistent fever does not reflect clinical improvement and may warrant further assessment or intervention. B. WBC count of 17,500/mm³: An elevated white blood cell count suggests ongoing infection or inflammation. Normal WBC counts typically range from 4,000 to 11,000/mm³. This elevated value indicates the body is still actively fighting an illness. C. Respiratory rate of 28: A normal adult respiratory rate is 12–20 breaths per minute. A rate of 28 suggests the patient is still experiencing respiratory distress, possibly due to hypoxia or infection, which does not indicate improvement. D. Oxygen saturation of 94% on 2L/nasal cannula: An SpO₂ of 94% on low-flow oxygen shows that the patient is maintaining adequate oxygenation with minimal support. This indicates an improving respiratory status and better gas exchange, reflecting clinical progress.
