Step-by-step explanation:
When providing prehospital care to an unconscious patient of undetermined cause, it is important to focus on stabilizing the patient's condition and ensuring they receive appropriate medical attention. This may include assessing and maintaining the patient's airway, providing oxygen if needed, monitoring vital signs, and initiating intravenous (IV) access for fluid administration.
