RCW 11.88 addresses issues regarding guardianships for incapacitated persons. See http://app.leg.wa.gov/RCW/default.aspx?cite=11.88.030.
You should retain counsel.
There are forms online - for example: https://www.courts.wa.gov/forms/?fa=forms.contribute&formID=91
Sometimes guardianship issues require litigation. See In re Guardianship of Decker, 188 Wn. App. 429, 353 P.3d 669 (2015).

I am sorry to learn of your husband's condition. Washington State law does not have a provision for a "temporary guardian". As stated in the prior answer RCW 11.88 addresses the procedure for the appointment of a guardianship and the authority of a guardian to act on behalf of an incapacitated person.
