Graveyard Alive (2003) on Netflix

A woodsman is up to no good foraging through the grounds of his backyard forest. He shows up at the local hospital with an axe casually stuck in his head, and his face not looking too good either. He is placed under the care of handsome Dr. Dox and homely Nurse Patsy. The woodsman expresses his attraction to Patsy by biting her on the arm, inciting a slowly-spreading zombie contagion in the hospital. In true horror film fashion, Patsy's human to monster transformation comes with a symbolic side effect. Once a perennial black sheep among the cliquish nurses and invisible to the Casanova Dr. Dox, Patsy's makeover includes a severe attitude change that turns her into the hospital sexpot.
