I've chosen to do a big project on a patient I had (first clinical ever!) who experienced very profound intolerance to pain medication (Percocet, Ultram) (manifesting low BP, confusion, unresponsiveness, lethargy-obtundation). He had to be taken from the TCU and hospitalized when he was found unresponsive. Upon eval, meds were not administered incorrectly. It was decided pt could not 'tolerate anything stronger than Tylenol.'The Dx I've proposed (and my instructor encouraged) is "Altered Level of Consciousness." I can't find any resources on such a diagnosis, however, and I'm wondering if there is a more astute Dx I should be ferreting out. Nothing I've seen quite matches the narcotic intolerance/reaction picture I think my instructor and I want to deal with in the form of a sound nursing Dx. Any help appreciated.
