It depends on your facility protocols. We have a lot of nursing driven policies such as removing foleys, doing repeat blood work, EKGs, giving atropine/épi/defibrillating during critical situations, doing ABGs and others. When nurses enter orders, doctors always have to co-sign. I also work in the ICU, I feel like nurses have more autonomy there. More importantly, Is it an order that will expedite patients’ care to prevent a problem? Is it an order that will potentially harm the patient? You have to always know that your priority is your patients’ safety.
