Final answer:
The correct guideline for a nurse witnessing a will is that witnesses do not have to read the will, but must witness the signing and should not be beneficiaries of the will. Typically, at least two witnesses are required.
Step-by-step explanation:
When a nurse is asked to witness a testator's signing of a will, there are specific guidelines that need to be followed to ensure the document's legal validity. The correct guideline regarding a nurse's role as a witness is that Witnesses to a signature do not need to read the will. This means that as a witness, the nurse is verifying the act of signing itself, rather than acknowledging agreement with the contents of the will. Witnesses must observe the testator signing the will, and cannot sign as a witness at a later time without having seen this. Furthermore, a beneficiary of the will is generally not allowed to act as a witness, as this can create a conflict of interest. Lastly, most jurisdictions require at least two witnesses for the will to be valid, therefore a single witness would not be sufficient.
When it comes to witnessing a testator's signature on a will, there are specific guidelines that nurses should follow. One important guideline is that witnesses to a signature do not need to read the will, as their role is simply to verify the testator's signing. Another guideline is that witnesses must observe the signing of the will and cannot sign it at a later time. Additionally, a beneficiary to a will is generally not allowed to act as a witness, as it could raise questions about the validity of the will.
