I love nurses. A good nurse is worth her weight in gold, and I've worked with some of the best of them. Sadly, I have also learned that a bad nurse can really make your life miserable.
When I was a resident, I worked with some nurses who seemed sometimes bafflingly incompetent. They would page me about the most ridiculous things. This was one of my favorite pages I got from one of them:
A nurse paged me at seven in the morning. She was calling because she need to get the phone number for a patient's mother, so that neurosurgery could get consent to do surgery on him.
1) I already given neurosurgery that phone number (more than once)
2) consent had already been obtained last week
3) the patient was already in surgery
