What is the primary action to take when a patient arrives with epistaxis?

When a patient presents with epistaxis, or nosebleed, the primary action is to pinch the anterior portion of the nose with moderate force for 5-10 minutes. This method is effective because it applies pressure to the source of the bleeding, helping to constrict blood vessels and reduce the flow of blood. The anterior portion of the nose is where most nosebleeds originate, making this technique not only practical but a first-line approach for managing this condition.

This measure can significantly aid in stopping the bleeding before further intervention is needed. Maintaining pressure for the recommended duration allows sufficient time for the bleeding vessels to clot, thus resolving the immediate concern.

While other options might contribute to the overall comfort or stability of the patient, such as providing hydration or positioning them supine, they do not directly address the bleeding issue. Pinching the nose focuses specifically on controlling the epistaxis, making it the most appropriate primary action to take in this scenario.
