Final answer:
Among the provided options, the nurse should report an unsteady gait with a widened base and shuffling steps as it suggests a potential neurological issue needing further medical assessment.
Step-by-step explanation:
The student's question pertains to assessing an older adult client's gait during a physical examination. In this scenario, the nurse observes the client's walking pattern for any abnormal movement that could indicate potential health issues. The nurse should report an unsteady gait with a widened base and shuffling steps to the provider, as this is a finding that may indicate an underlying neurological problem, such as Parkinson's disease or proprioceptive deficits. It is essential to ensure that the client receives appropriate medical assessment and possibly intervention to address any health concerns related to gait abnormalities.
