Final answer:
In conversion disorder, the expected finding is an involuntary loss of a sensory function like blindness or deafness, with no physical cause.
Step-by-step explanation:
A nurse assessing a client who has been diagnosed with conversion disorder would expect to find involuntary loss of a sensory or motor function without a physical cause. Conversion disorder, also known as functional neurological symptom disorder, manifests with neurological symptoms that cannot be explained by medical evaluation. Symptoms of conversion disorder often include involuntary loss of a sensory function such as blindness, deafness, or paralysis, as well as involuntary movements or gait problems. These symptoms are not intentionally produced or feigned, and they are typically precipitated by psychological factors.
