The immediate goal is to stabilize the patient, particularly by ensuring adequate oxygenation. Initiating high-flow oxygen via a nonrebreather mask is crucial to support the patient's respiratory function and improve oxygen delivery, especially given their vital signs indicating potential shock. This step is essential before considering other interventions such as fluid resuscitation or antimicrobial therapy."}
