Final answer:
Option C. Indicators of sensory overload in the vestibular system include dizziness, nausea, and discomfort. Tests like the Romberg test are used to assess the system's function, and symptoms similar to sensory overload may be observed in conditions like motion sickness.
Step-by-step explanation:
Some indicators of sensory overload during testing of the vestibular system include dizziness, nausea, and discomfort. These symptoms can occur when the vestibular system, which is responsive to movement, gravitational forces, and changes in head position, is overstretched or overstimulated. Activities that stimulate the vestibular system—like tilting or turning the head rapidly—may lead to a state where the brain's ability to process motion-related information is overwhelmed, leading to these indicators of sensory overload.
In more specialized testing of the vestibular system, specifically with the Romberg test, a patient's equilibrium is challenged. This tests their proprioception (sense of body position) and reliance on vestibular input to maintain balance without visual cues. Improper function of the vestibular system can lead to a positive Romberg sign, manifesting as a loss of balance when the patient's eyes are closed.
