So much for not hurting anyone

My patient came in the hospital with hypertensive urgency. I wrote her two care plans, and did my pathophysiology statement, and wrote up all of her meds. I was ready. I came in the morning and gave her 0800 meds, shortly after that my RN comes to me and says "Her BP is at 193/96, you need to give her 1000 meds now". My instructor was right there with me, so she said ok and off we went to give her 1000 meds. She has Metropolol 20mg, Vasotec 5mg, and a Nitro patch. As I'm pulling these I'm thinking that is an awful lot of BP meds and the nitro on top of it all. But of course I rationalize it, my RN told me to do it, she has been working here for 30 years, and my instructor is looking over my shoulder, everything will be fine. Right? Right!

NOT.

About 30 minutes later my tech calls me and says "What the HELL did you do to your patient?". I'm a little confused and taken back at first and she proceeds to tell me that my patient is not feeling good and her BP is at 80/42!!! OH MY GOSH!!! I gave her the dang medication! I walk in the room and she is absolutely weak, completely dizzy, and a little out of it. Her husband was there and they were both very upset with me. I called my RN who walked in there and all she told my patient was that she was going to have to talk to the doctor and that he was going to lower her dosage. And she walks out! I was standing there like a complete moron not knowing what to do next or say! I apologized to my patient and her husband and asked if there was anything I could do for them. They said no and I left. The rest of the day I checked her BP every 30 minutes. It eventually went up, but it never went up to normal rangers. We left at 1630 and she was feeling a little better, still dizzy, and her BP was up a little bit. We also removed the nitro patch hoping things would be better.

I felt so bad! I understand logically I did nothing wrong. We couldn't really know that she would bottom out like that. But I feel like I should have known better, you know? Like I should have known to just giver her one BP med and check her BP 30 minutes later and if it was still high to give her the other one. I think when I'm an RN that's what I'll probably do.
