I am a nursing student completing my first round of clinical. Currently clinical is at a rehab facility. Today while changing the dressing of a stapled and sutured hip surgery incision I became lightheaded. It was almost to the point of passing out. I had to sit down, cool off, and calm down. This has happened once before. When I saw my Mom's incision at a follow up appointment. In both instances it had been 10+ hours since I had last eaten. I understand that this could have had an influence. However, this makes me extremely nervous that I will not be able to hack being a nurse. Has anyone experienced the same or similar situations? If so, I would love and appreciate any insight and advice. Thank you!
