I want to preface my topic with the following: I am a relatively new traveler, just had my first day of orientation at my second travel assignment but have been a nurse for 9 years. Admittedly, 8.5 years of my experience is in one facility (a Level I trauma ICU) so my experience is fairly limited in terms of facility protocols.
Anyway, I just heard for the first time this morning that you should NEVER administer two electrolyte supplements (such as KCl & Mg) simultaneously, even if it's thru two separate lines. Now I do not like to take orders like these at face value...I question everything I don't understand so that I can make sense of it. And that's what I did...I questioned the nurse orienting me, of course it came across badly as though I was discounting their policies. She couldn't provide me any rationale so I did as she said but then went to pharmacy who confirmed my knowledge (or lack there of) that this would be an issue. He didn't seem to have any idea the nurses followed this "policy". So then I went to the nurse educator who essentially said this was policy and I was to follow it regardless, even though she wasn't able to show me any such policy or even knew if one existed. It's just "the way we do it". The charge nurse told me, "It would be like writing a policy to 'not jump off the roof'...you just know not to do it." Well apparently that isn't true since I've never heard it in my 9 years of nursing. Just to be clear, this is also a level I trauma ICU so they are both similar facilities and are both held in high regards.
So, my question to you...what's your knowledge & experience with this and if it's something you've always "known to be true", what's the rationale?
Thanks in advance for helping me understand since the facility could not.
