Just curious - you were consenting patients for surgery?
Or were you helping to get paperwork together, to fill out paperwork legibly and subsequently witnessing the consent? Consent is the responsibility of the physician or (depending on procedure/training of individual) midlevel practitioner (PA, NP, CRNA).
I witness consents all the time, I'm an OR RN in a Level I trauma center. But unless I watch the conversation and can as such say for certain the requirements for patient understanding were acheived, I have six questions I have to ask (per my facility policy) to be able to sign there. Unless a consent is witnessed at the time it was signed you have to make sure the patient understands the procedure(s), risks and benefits/alternatives were discussed - etc.
I certainly don't see an issue with obtaining vitals and patient teaching. I did plenty of that without getting paid
. In fact, I paid for the opportunity to do those things in school
I agree with the others - list the name of the physician or practice as the employer, dates of employment, list the physician as your supervisor, and provide appropriate contact information - just like you would for any other position. You can include the letter with your materials if asked for an interview.
