A female client with degenerative disc disease and chronic sciatica is describing numbness and tingling down her left leg. Which assessment should the nurse obtain first?

Rationale: A. Duration of sensation: This helps to determine if the symptoms are acute, intermittent, or continuous, which can provide clues about the severity of nerve compression or irritation. Changes in duration, frequency, or intensity can indicate worsening nerve impingement or the development of a new neurological deficit requiring immediate attention. B. Precipitous activity: While it's useful to know what activity triggered the symptoms, this is secondary to understanding the timeline and progression of neurological signs, which carry more urgency. C. Time of last analgesic: Pain control is important, but the priority is evaluating potential nerve compromise. Numbness and tingling may reflect compression or damage that cannot be addressed by analgesia alone. D. Gait coordination: Assessing gait coordination is important to evaluate the functional impact of the neurological symptoms, which could indicate more severe nerve compression affecting motor pathways. However, it is an assessment of a motor function. The client is describing sensory symptoms.
