In the scenario where Dr. Powder wants her patients to sign all forms electronically, the most likely true statement is:
The patient can sign if they have a personal protected password.
This aligns with the principles of electronic signatures and HIPAA compliance, as long as the electronic signature system used also maintains the security and confidentiality of patient information. Electronic signatures are generally permissible under HIPAA, provided that proper safeguards are in place. The other options are not accurate statements regarding HIPAA regulations or typical practices related to electronic signatures.
