Which of the following are considered lifesaving steps?

The correct response identifies the essential actions that are critical in a life-threatening situation. Opening the airway is fundamental because it ensures that oxygen can enter the lungs, which is vital for survival. Stopping the bleeding is equally crucial; uncontrolled bleeding can lead to rapid deterioration of a patient's condition and can be life-threatening. Preventing shock involves measures to maintain blood circulation and ensure that vital organs receive adequate blood supply.

These steps are foundational in first aid and emergency response protocols aimed at stabilizing patients until professional medical help can be provided.

The other options, while they may include useful actions in different contexts, do not focus specifically on the immediate lifesaving measures that are necessary in emergencies. For instance, restoring supplies and preventing infection are important for long-term care but are not immediate lifesaving measures. Administering pain medication can be pertinent for comfort but does not address the immediate needs for life preservation.
