Which action is appropriate when updating patient demographic information?

When updating patient demographic information, confirming that the patient signed and dated the patient information form is essential. This step verifies that the patient has actively engaged in the process of updating their information, ensuring that the data captured is accurate and reflects the patient's consent. A signature indicates that the patient acknowledges the details provided and agrees to the contents of the form.

Additionally, a signed and dated form serves as a legal record, safeguarding against any disputes regarding the accuracy of the information presented. It helps maintain a professional standard for documentation in healthcare settings.

While other choices may involve aspects of patient information management, they do not specifically address the need for confirming consent and acknowledgment through a signature, which is a crucial element in maintaining accurate and responsible patient records.
