Which physiological function should a nurse monitor in a client with a brainstem injury?

In clients with a brainstem injury, monitoring respiratory effort is crucial because the brainstem contains vital centers that control autonomic functions, including breathing. The medulla oblongata, part of the brainstem, is particularly responsible for regulating the rhythm and depth of respiration. An injury to this area can compromise respiratory function, leading to apnea or abnormal breathing patterns.

Therefore, observing respiratory effort can provide immediate insights into the client’s respiratory status and overall stability. Alterations in breathing can indicate a deterioration in condition that may require urgent medical intervention. While other physiological functions such as digestive function, circulatory response, and motor coordination are important, they are not as critical to monitor immediately in the context of a brainstem injury as respiratory effort.
