Depending on the situation, you will want to respond quickly and make yourself available to assist the doctor in any way you can. Be aware of the surroundings and also observe the patient. Your best response will be one where you are sensitive to the situation by listening closely to the doctor and nurses involved. There may not be anything you can do to help, but if you get in the way, you could definitely create more problems. Ask what you can do and pay attention. If you need to step aside, be respectful and understanding.
