Never go into a room to start an IV, draw a blood gas or perform any other such task with only one syringe, needle, kit or whatever you need to get the job done. If you do, your fate is again sealed and you are certain not to get what you need on your first attempt.
On a bad day, never utter the words "God give me strength." You are sure to be given only trials for being so cheeky. It's OK to ask for wisdom. Like in "please God, guide my feet and hands in getting to the drug pyxis quick enough and picking out the correct concoction of drugs that are going to sedate this maniac." That's an OK plea.
When you have finally discharged a patient that has been on your unit for forever and a day (not an exageration), never talk about that patient. Never say that patient's name out loud. Never discuss the patient in even vague terms. In fact, try not to think of that patient at all. It's like Beetlejuice. Say that name 3 times and that patient will be readmitted quicker than you can run to fetch the holy water.
Never ignore the patient who tells you he is going to die. All may look well at a glance but he may know something you don't. Ignore him at your own and especially his peril. We call this a feeling of impending doom. It is affirmation that someone let the Q word slip.
These warnings and superstitions should be practiced in all areas of life. For instance, never discuss the sure signs of spring in Michigan unless it is July. You will most certainly be shat upon from the heavens above with fluffy white flakes that are certain to ruin your Friday drive to work. I did it. We will get 3 to 6 inches of heavy white snow tonight. It will end just in time for me to drive to work. I can't believe I left the holy water at work........
