Create a 3D avatar of a disheveled, zombie-like nurse with sunken, bloodshot eyes, long tangled hair, and rough, scarred skin. The avatar should be highly detailed, with textured and decaying flesh, exposed bones, and sharp, jagged teeth. The nurse should be wearing a tattered, blood-stained medical uniform, with ripped and frayed fabric. The hair should be long, unkempt, and matted, with dirt and debris visible. The eyes should be sunken and hollow, with no reflections or highlights. The avatar should be posed in a hunched, menacing stance, ready to attack. The overall effect should be disturbing and unnerving, evoking fear and horror in the viewer.
