I would like to replace my mother's soiled carpeting. Will this be an allowable expense regarding Medicaid look-back?

My mother has dementia and has lost the ability to control her bodily functions and unfortunately she has light oatmeal colored carpeting. I would like to replace the soiled nasty carpeting with some laminate flooring which is much easier to maintain and clean up and keep the apartment somewhat odor-free also I would like to install a walk-in shower ( she owns a small one-bedroom condo ) which entails having the tub removed because she can no longer get in and out of the tub. My question is will this be an allowable expense regarding Medicaid look-back. Eventually we may have to look into memory care or nursing home for her.
