Final answer:
The EMT must focus on the needs of the patient.
Step-by-step explanation:
The correct answer is C) Patient.
Once a scene is free of safety hazards, the primary focus of an EMT is to recognize and attend to the needs of the patient. This includes assessing the patient's condition, providing appropriate medical treatment or first aid, and preparing the patient for transportation to a hospital if necessary.
While bystanders, family members, and rescuers may also need attention and support, the immediate priority is the well-being of the patient.
