Trauma Nurse Core Course (TNCC) Practice Exam

Assessing nerve function in trauma patients is crucial for determining the extent of injury and planning for treatment. The most effective method to assess nerve function involves evaluating sensation, range of motion, and reflexes.

Sensation tests help identify any loss or alteration in feeling, which can indicate nerve damage. By checking different areas of the body, healthcare providers can determine if the injury has impacted the sensory pathways. Range of motion tests are essential for assessing mobility and the functional integrity surrounding the joint and muscle systems, which can also reflect nerve status indirectly. Reflex testing assesses the neurological response through muscle contractions in reaction to a stimulus, revealing the functionality of specific pathways.

In contrast, options like measuring blood pressure and respiratory rate focus more on the overall physiological status rather than direct nerve function. Chemical blood tests and imaging, although important in trauma evaluation, provide insight into metabolic and structural conditions instead of nerve function specifically. Additionally, relying solely on patient history and physical examination without objective assessments could lead to overlooking neurological deficits that require immediate attention. Thus, the integrated approach of sensation, range of motion, and reflexes offers a comprehensive assessment of nerve function in trauma patients.
