Never ever give ice water to a cardiac patient. This triggers a vagal response resulting in life threatening arrhythmias.
Never allow a patient on Coumadin to use a standard razor. An electric shaver must be used to prevent exsanguination.
The open end of all pillow cases must face away from the entry door to the room. On wards, the open end of pillow cases must face away from the window.
A patient could not get out of bed (OOB) to use the bathroom without a BRP (Bathroom privilege order.) This one really bothered me. Since when is going to the bathroom a privilege?
If the patient vomited on a dietary tray, nursing service must clean it up. This rule was especially unfair since it was probably the food that triggered the emesis.
Our neuro OR had big notice on the door: "NO TALKING OR LAUGHING NEUROSURGERY IN PROGRESS." I guess I will have to stroll down to the heart room before busting a gut.
Patients with abcesses or infections were in a special classification - Contaminated Case which had all sorts of special rules such as being scheduled at night after all other cases were done, everything that exited the room except the patient double bagged, and scrubbing the tile walls upon conclusion of the case with some sort of toxic witches brew of disinfectant.
After finishing a case in the OR all instruments must be returned to Central Supply unratcheted. If you really wanted to get a rise out of the old geezers in Central Supply, return a knife handle with the blade attached. Witnessing an old battle hardened nurse moving toward you at the speed of light with a knife in her hand is very frightening.
The grounding plate for the Bovie must be placed exactly in the center of a patient's buttocks. This rule caused much animated discussion and and arguing about gluteal anatomy. The grounding plate was the size of a cookie sheet and the best strategy was to place it on the table prior to the patient's transfer from the Gurney. I always thought this must be a really bad pre-induction experience for the patient. Imagine being frightened by the strange environment complete with scary, sharp metal objects and then being plopped onto a cold metal plate all gooey with conducting gel. YIKES and OOW that's cold.
The circulating nurse must be at the patient's side during induction even if there is nothing for her to do.
Use only a glass syringe to administer that Paraldehyde and make sure the number on the syringe barrel matches the number on the syringe because old syringes were not interchangeable. Don't you just love that Paraldehyde-Paregoric-coffee ground emesis smell on the alcohol detox ward. It was a great deterrent when the urge to imbibe struck. "I think I'd just like a Coke tonight. That Paraldehyde smell is imbedded in my nostrils."
I am certain there are many more, but I seem to be having one of my brain freezes. Don't forget to hold that cold water when caring for a cardiac patient!
