A nurse is preparing a patient for a scheduled endoscopy. The patient says, "I'm not sure why I need this test. The doctor said something about looking for bleeding, but I didn't really understand." What is the nurse's best action?

Notify the provider that the patient has questions and requires further explanation before signing.

Tell the patient to sign the form now and ask the physician questions after the procedure.

Reassure the patient that the procedure is routine and have them sign the consent form.

Provide detailed information about how the procedure is performed so the patient can sign.
