Which of the following actions should a medical administrative assistant take when obtaining a signature on an informed consent document

This option is inappropriate because informed consent must be obtained before the procedure takes place. Witnessing the signing after the procedure does not ensure that the patient was adequately informed beforehand, which is a critical legal and ethical requirement.

This choice is ineffective, as it does not facilitate immediate confirmation of understanding prior to the procedure. Informed consent should be obtained in person to allow for any clarifications or questions the patient may have before they undergo treatment.

While this option suggests that the patient reads the form, it does not ensure that they fully understand the content or implications of the document. The process of obtaining informed consent must include a dialogue to confirm understanding, which is lacking in this choice.
