I was able to witness a code one day during my clinical. I was in the cardiac cath lab when they brought him in. One of the guys who worked there started doing compressions, he was a very muscular man who worked out at the gym frequently. Once he initiated compressions, the patient started bleeding from the mouth and nose. They had been working on this patient in the ER for over an hour already and did not have this problem. Was this staff member doing compressions too deep?

I am about to graduate and will be ready to start looking for a job soon. I asked my preceptor what kind of tips she had for me during an interview. She said it was important to have some questions for them at the end to show interest in the job. I'm wondering what the most important things to know before going into an interview would be?
