Which of the following procedures is essential for airway management?

Using a laryngoscope for intubation is a foundational procedure in airway management because it allows a medical provider to visualize the vocal cords and facilitate the insertion of an endotracheal tube. This is critical in situations where a patient is unable to maintain their airway due to various medical conditions or emergencies, such as respiratory failure or unconsciousness. Intubation secures the airway, ensuring that oxygen can be effectively delivered to the lungs, which is vital for life support.

In the context of airway management, the other options do not play a direct role. Administering oral medications does not directly support or maintain the airway. Providing nutritional supplements is important for overall health and recovery but does not address immediate airway management needs. Performing physical therapy may assist in overall rehabilitation but is unrelated to securing or managing a person's airway in an emergency situation. Thus, the correct response highlights a critical skill in emergency medical care that ensures patient safety and effective oxygenation.
