Will survive? Let's be realistic, she was bit and Clem can cut her hand off or kill the walker. Clem's hatchet has so much zombie muck on it that cutting into Sarita is just going to spread the infection further. Also, the group is in a middle of a herd she would bleed out way before she received medical attention. Not to mention that they probably didn't bring much supplies, and the loud ass scream (more than Sarah's) is going to draw all the walkers to her. Now if you kill the zombie she doesn't make noise but her chances of survival are slim there.
