Your example would never happen. DNR (do not resuscitate) orders are suspended during and immediately after surgery because anesthesia itself carries that risk. Unless a patient specifically tells the anesthesiologist not to resuscitate, which you can be sure will be very well documented and part of the consent for anesthesia, the resuscitation will happen. ICU and Recovery Room RN for 35 years and counting.
WTF?
I never posted anything about DNR.
Look back.
