Ah, my apologies, I’ve not yet heard of such a thing as “vitemin.”
First, try to talk to the nurse in private. Do not be accusatory, just remind them of the agency policies regarding wound care, & talk about what you observed and emphasise the wish to help, not criticise. If they are antagonistic and/or do not amend their wound care practice, then it will be necessary to speak with your supervisor about the matter. Ultimately, the duty of care to your patients is more important than one nurse's pride.
Heart rate is your answer
Pretty sure it is stress, because around that age everything in your life is coming together at one time, friends, family, your future, so I would believe the answer to be STRESSED!
Hope this helps, if not, comment below please!!!
