Which finding indicates that immediate intervention is needed for a client with a traumatic brain injury?

A respiratory rate of 30 breaths per minute is concerning for a client with a traumatic brain injury and indicates the need for immediate intervention. This elevated respiratory rate can be a sign of respiratory distress or a compensatory mechanism in response to increased intracranial pressure. In this situation, the body may be attempting to increase oxygen delivery to the brain or compensate for metabolic acidosis. Rapid or labored breathing could also indicate a worsening neurological status or impending respiratory failure.

In contrast, a blood pressure of 110/70 mmHg is typically within an acceptable range for a stable adult and would not immediately suggest a critical issue in the context of brain injury. A heart rate of 60 beats per minute, though on the lower end of normal, is not uncommon in patients who may be resting or relaxed. Similarly, a temperature of 101°F, while elevating and necessitating monitoring, does not typically require immediate intervention unless accompanied by other alarming symptoms. In summary, the respiratory rate is a pivotal sign indicating that the client may be in a critical state requiring urgent medical attention.
