The medical provider who is trained in and will perform the procedure is responsible for explaining risks, benefits, alternatives, and answering questions. Your signature only indicates that you witnessed the patient's signature. Can you sign without an MD present? Yes, technically. Is your patient legally "informed," and are you advocating for your patient if you allow him/her to go to a medical procedure without speaking to the MD first? No, and allowing your patient to undergo a procedure without informed consent doesn't meet the minimum standard of practice. You can, of course, obtain consent for all nursing procedures independently.
