Which of the following is an ALS intervention?

The correct choice identifies a procedure associated with Advanced Life Support (ALS) practices. Among the options given, physical restraints offer a critical intervention in certain medical emergencies, particularly in cases of severe agitation or combative behavior that could endanger the patient or medical personnel.

In the context of ALS, physical restraints may be employed to ensure the safety of the patient and the healthcare team during critical care situations. While this may not be a typical first-line intervention, it can be necessary in scenarios where the patient's condition warrants maintaining control to prevent harm, particularly in cases of delirium or psychiatric emergencies.

Other interventions listed, such as giving epinephrine, suctioning, or administering oxygen via nasal cannula are indeed life-saving measures but they are more common in Basic Life Support (BLS) protocols or other supportive care practices, rather than classified explicitly under ALS interventions, which often focus on managing complex medical crises and advanced airway management.
