There is such good advice and support here...I will try to be the devils advocate (although hard)....
Okay...hmm...my only advice is to always remember, TREAT the patient not the machine...and along with this comes doing an immediate MANUAL BP and pulse then report to the nurse. Cause frankly...my first question would be..."Did you do this on the machine? What is the manual????". If that wasn't done, I make you go back! (and if I am not up to my eyeballs in stuff...I go with you, or have you wait till I can...not going to leave ya hanging, but that is me!).
So lesson one, always do manual on any odd readings! You would not believe how many times things are solved this way by machines not working correctly or simple anatomy not meching with the machines limited diameters!
(I take all MANUAL...I don't trust dinamaps or even pulse ox...9 times out of 10 they are incorrect and cause undo panic!).
Okay the biggie in this case must have been FAMILY! Want a bad situation 50 times worse...have a family member in the room! LOL! (you students will learn this...). So oops, family member getting anxious...now we have a situation! That could very well be what set your nurse off. Many nurses are awesome with patient care, but not as good with family dynamics and communication...and this would tweek them out (especially on a busy day, and I don't mean running as much as mentally busy!). So we started with a MACHINE saying a high bp...no manual checked...and now an overly anxious family member..all from a VS check...okay high gear time with complications!
ALSO! A MD may have NOT wanted the patient on their home meds because they were not working and wanted to check baseline without them to be able to prescribe something more appropriate...so don't assume that that med given by the nurse was a wrong one clinically...we run by the whim of the MD my dear...and we don't prescribe. Plus many MD's get very egosentric if you question or give suggestions...and will actually STOP where they are an order nothing! Another pearl of wisdom...KNOW your MD's and their little personality tid bits...she may have known this Doc better than you and had to approach it slowly as not to screw up the works!
So okay..lets see where we are now...high bp on a MACHINE, no manual taken, anxious family member, and the social dynamics of dealing with the MD and still...get things done to satisfy the patient, family, MD, and you!
I think I can safely stop here...just think about these dynamics because they happen ALL the time! Another part of the art of nursing you will learn as you go along (especially the fact that FAMILY PANIC over ANY medical term or vital sign, and expect instant results from the RN to correct it!!!!!! They don't know the hurdles we have to jump through to get a simple order!)....
HOWEVER...you did excellent in reporting that BP in a timely mannor! AWESOME! Just next time take a manual then report!
Being called in however...your a student...what good is that??? Oh yeah...it scared you, made you doubt yourself...not appropriate or pro learning!!!!! I think that was a catty thing to do...it isn't like you aren't stressed enough learning...shoot! I would talk to you after and during actually I did my implementations to solve the issue to teach you...so next time you know what is involved in solving a probelm on many levels! That would have been much more proactive!!!!!!
Take it as a learning experience because this not only happens in school...but in the job arena as well! Learn how you deal with this personally and professionally...that would be the greatest thing to take from this!!!!!
Good job! I would have totally understood your reaction and guided you through the process with a few laughs along the way (cause that is how I teach!).....
