I don't remember the exact number for the BUN and I think Creatinine was like 2? Just know that these values had been trending up for the last few days. The patient is a 70+ y.o. s/p two Heart Caths within two days and comorbidities, CHF, Lung Disease, Diabetic, CAD. His O2 sats were in the 95-97% on two liters of oxygen. The kicker is, that he night RN had called Rapid Reponse on her shift, due to the patient c/o SOB and Chest pain, which she had administered Morphine.
