Which of the following is an essential intervention for airway management?

Positioning to maintain airway patency is a fundamental intervention for airway management because it directly influences the ability to secure and maintain a clear airway for the patient. In emergency and critical care settings, ensuring that the airway is unobstructed is crucial for adequate oxygenation and ventilation.

Certain positions, such as the supine position (lying on the back) or the sniffing position (with the head slightly extended and tilted), can help align the airway structures, making it easier to manage and ensuring that the tongue does not obstruct the airway. Additionally, interventions like the recovery position may be used to help prevent aspiration in specific circumstances.

While other options presented in the question, such as providing dietary recommendations, displaying patient history, and conducting psychological evaluations, are important components of overall patient care, they do not directly address the immediate needs for effective airway management. In critical situations, such as during emergencies or in patients requiring transport, maintaining a patent airway is the priority intervention to prevent life-threatening problems.
