No such proceeding

It appears that protective services can generally only be provided with consent. Nev. Stat. § 200.5093(8) states: 

If the investigation of a report results in the belief that an older person or vulnerable person is abused, neglected, exploited, isolated or abandoned, the Aging and Disability Services Division of the Department of Health and Human Services or the county's office for protective services may provide protective services to the older person or vulnerable person if the older person or vulnerable person is able and willing to accept them.

However, the department may seek further action in probate court if necessary: 

The local office of the Aging and Disability Services Division of the Department of Health and Human Services or the county's office for protective services may petition a court in accordance with NRS 159.185, 159.1853 or 159.1905 for the removal of the guardian of an older person or vulnerable person, or the termination or modification of that guardianship, if, based on its investigation, the Aging and Disability Services Division or the county's office of protective services has reasonable cause to believe that the guardian is abusing, neglecting, exploiting, isolating or abandoning the older person or vulnerable person in violation of NRS 200.5091 to 200.50995, inclusive.

Neb. Stat. § 200.50986.  To learn more about the right to counsel of adults subject to guardianship matters, please see Legislation, Guardianship/Conservatorship of Adults - Protected Person.
