Texas- Quit Claim... Warranty Deed.. Nursing Home...confused

[Erica Martin]

My spouse was given a property through a quit claim deed by a family memeber. Documented (10/16) Filed (06/18).

He tried selling the house  but quickly found out in Texas he could not use the quit claim deed to sell the house. He  is trying to get the person to sign a warranty deed. The problem is the person is in a nursing home and other family members are saying this will affect their Medicaid.
My questions are: Will this affect their medicaid? The quit claim deed was signed while the person was in a nursing home and the price was $10. Also what is the Quit Claim actually for anyway?
