Sounds like you had a bad week with things happening that were beyond your control (computer crashing, no dialysis order). How would you know your patient is going to dialysis if there was no order written for it? You're not a mind reader lol. Bad weeks happen sometimes, and hopefully this week will be a good week. If you're always having bad weeks like the one you mention, well, then I would find another area of nursing, another unit. I've only been yelled at once or twice, as a scapegoat type of thing: me being the scapegoat lol, and it just made me not respect the physician doing the yelling. And, by yelling, I mean denigrated, not actual yelling. The physicians I work with are respectful.
When this happens, you need to stick up for yourself. Be diplomatic, but be assertive and stick up for yourself. If a physician "yells" at you for not knowing about dialysis, then just state: "I'm not omniscient. There was no order written, and no mention was made of dialysis." If family yells at you, stick up for yourself, and state that you're sorry about x, y, z, about the inconvenience or whatever they're yelling about, understand their perspective and be helpful, but make it clear that yelling is not acceptable behavior, and you would appreciate that they talk to you rather than "raise their voice" (sounds better than saying they're yelling lol).
