A nurse in a rehabilitation unit is assessing a group of clients who have a traumatic brain injury. Which of the following clients requires a priority referral?

A. A client who needs assistance when ambulating: Difficulty ambulating increases fall risk and requires physical therapy, but it is not immediately life-threatening. This client needs support but does not take priority over airway or aspiration concerns. B. A client who consistently has difficulty using utensils while eating: This reflects impaired motor coordination and may require occupational therapy. While important for independence, it does not present an urgent safety or health threat. C. A client who has expressive aphasia: Expressive aphasia affects communication but does not compromise airway or physical safety directly. Speech therapy is beneficial, but it is not the most urgent referral. D. A client who consistently coughs after drinking liquids: Coughing after drinking indicates possible aspiration due to impaired swallowing reflex. Aspiration can lead to pneumonia and respiratory compromise, making this client the highest priority for immediate referral to a speech-language pathologist for swallowing evaluation.
