Which of the following is a major area to assess in a person who has sustained a traumatic brain injury?

A comprehensive assessment of an individual who has sustained a traumatic brain injury encompasses various functional domains impacted by the injury. Each of the areas mentioned—swallowing, receptive language, and speech systems—can be significantly affected by traumatic brain injury.

Swallowing is critical because brain injuries can disrupt the neurological control necessary for safe and effective swallowing, potentially leading to complications like aspiration.

Receptive language is another major area of concern, as individuals with brain injuries may experience difficulties understanding spoken or written language due to the injury's impact on the brain regions responsible for processing language.

Speech systems, which include the physical aspects of producing sound and the cognitive aspects of organizing thoughts for verbal expression, are also vital to evaluate. Changes in articulation, voice quality, and the clarity of speech can occur post-injury.

Assessing all these areas provides a holistic view of the patient's capabilities and challenges, allowing for tailored interventions that address each specific need. Thus, the correct answer embodies the comprehensive nature of evaluation required for individuals with traumatic brain injuries.
