1. Don't argue w/ nurses, unless it's patient care that's involved. They are not worth it. It's like arguing with a 7 year old. You have better things to do, and talking to a nurse just drains about 10 brain cells per minute.
2. Placement is everything. The moment a patient is admitted, you need to think, "What do I need to do to get this patient discharged?"
3. When calling in a stupid consult just say, "My attending wants this." They can't argue.
