Assignment topic! help please!

Maybe post this in nursing student assistance? Might get more responses that are relevant.

If you search in AN for "errors" or "my worst mistake" even you will find huge threads full of these, and most of them include what we learned from them. They should give you some ideas.

Here are a lot:

I am not sure exactly what your instructor is looking for so I am not sure if this will help or not.... Maybe you could do something along the lines of a nurse jeopardizing patient safety by connecting lines to the wrong port, which can be fatal. Some examples would be inadvertently connecting the tubing from a portable blood pressure monitor to a patient's IV and delivering a fatal air embolus. Another example would be delivering an oral substance/medication, such as breast milk (which was drawn up in an oral syringe), to a patient via his or her IV line. Always label syringes and trace the lines to the point of origin so you know exactly which line something is being connected to. If you need any help let me know.
