What is the appropriate first step for an EMT managing a patient with an open fracture?

When managing a patient with an open fracture, the first step should focus on ensuring the patient's safety and addressing any immediate life-threatening concerns. Controlling external bleeding is crucial because an open fracture can involve significant trauma and may lead to severe blood loss. This action helps to stabilize the patient's condition and prevents further complications.

After controlling bleeding, it's important to stabilize the extremity to prevent additional injury and alleviate pain. Stabilization aids in securing the fracture and protects the area from unnecessary movement, which could worsen the injury or exacerbate bleeding. This prioritization aligns with the primary assessment and management protocols in trauma care that emphasize addressing life threats before focusing on other interventions, such as immobilization or pain relief.

Other options, while relevant, do not adhere to the established priority of immediate interventions for trauma patients. Immobilizing the fracture without controlling bleeding first could lead to further complications. Administering pain relief is essential but should not precede life-saving actions. Reassessing vital signs is important but should occur after controlling major issues. Addressing external bleeding and stabilizing the extremity ensures a structured and effective approach in managing the patient's condition.
