An unresponsive victim of a diving accident is brought to the emergency department where it is determined that immediate surgery is required to save the client's life. The client is accompanied by a close friend, but no family members are available. Which action should the nurse take first?

Rationale A. The client's friend may not legally be authorized to provide consent unless they hold medical power of attorney or legal guardianship for the client. Without documentation of such authority, the friend cannot sign the informed consent. B. In emergency situations where a patient lacks decision-making capacity and there is no available legal guardian or next of kin to provide consent, hospitals may seek a court order to proceed with necessary treatment. However, this could delay emergency treatment. C. This is based on the legal and ethical understanding that saving the patient's life takes precedence when immediate action is required and consent cannot be obtained. D. Providing life support ensures that the client's immediate medical needs are addressed while efforts are made to locate a legal guardian. However, unavailability of next of kin should not delay definitive intervention
