Which of the following terms describes a procedure for examining the airway?

Laryngoscopy is the correct term that describes the procedure for examining the airway. This process involves the use of a laryngoscope, which is a tool that allows medical professionals to visualize the larynx, vocal cords, and other structures of the airway. This examination is crucial for identifying any obstructions, assessing injury, or facilitating intubation in patients who are unable to breathe adequately.

In contrast, a splenectomy refers to the surgical removal of the spleen and is unrelated to airway examination. Thyroidotomy involves making an incision in the thyroid gland, which is not specifically focused on airway assessment. Tonsillectomy is the surgical removal of the tonsils, primarily used to treat recurrent tonsillitis or obstructive sleep apnea, rather than for airway examination itself. Thus, laryngoscopy is the specific procedure among the choices provided that effectively serves the purpose of examining the airway.
