What characteristic is typically observed in clients with nerve injuries?

Clients with nerve injuries often exhibit paresthesia, which refers to abnormal sensations such as tingling, numbness, or a "pins and needles" feeling in the affected area. This occurs due to the disruption of normal nerve function, which impairs sensory signaling to the brain.

When a nerve is injured, it can lead to a variety of symptoms, including altered sensation. Paresthesia is particularly indicative of nerve damage because it originates from the nerves themselves and signifies that the sensory pathways are compromised. This symptom can vary in intensity and duration, depending on the severity and type of nerve injury.

In contrast, increased mobility is typically not a characteristic observed in clients with nerve injuries, as the injury often results in weakness or reduced control over the affected body part. Persistent muscle spasms may occur, but they are not as commonly associated with nerve injuries compared to paresthesia. Chronic fatigue can be related to many conditions but is not a direct result of nerve injuries specifically. Therefore, of the options presented, paresthesia is the most characteristic symptom linked to nerve injuries.
