Mr. Jenkins shows signs of retrosternal pain but is not in severe distress. What is the initial action the team should take within the first 10 minutes?

Initial action in any emergency situation, such as Mr. Jenkins experiencing retrosternal pain, should prioritize assessing and supporting the airway, breathing, and circulation. This step is crucial because it ensures that the patient's vital functions are stable and that any immediate life threats are being addressed. In the context of retrosternal pain, which may indicate a serious condition such as a heart attack, maintaining the airway and optimizing oxygenation are critical.

By assessing these vital signs, the medical team can gather important information to help guide further treatment decisions. Immediately addressing airway, breathing, and circulation also sets the foundation for further interventions, whether that means administering medication, considering intubation later if indicated, or arranging for transfer based on the patient's condition.

Other interventions, such as administering morphine for pain or considering elective intubation, should only occur once the primary assessment of the patient has been completed. Transferring the patient to another facility without first ensuring that vital functions are stable would be premature and could compromise patient safety. Thus, the focus should be on the initial assessment and support of the patient's fundamental life functions.
