bp regimen was slowly added back. gi consult service was involved during admission and given her stablized hematocrit it was felt she could be discharged with protonix twice daily, sucralfate and follow up with gi as an outpatient. there was no acute need for endoscopy during this hospitalization. . 2. pleural effusion/pulmonary edema on cxr, volume resuscitation with 3 units of prbcs with h/o severe as and chf. after she was volume resuscitated she was given her home lasix dose of 40mg po daily and was weaned off of supplemental oxygen. 3. leukocytosis: patient had a significant leukocytosis, but no left shift, and a predominance of lymphs, with an absolute lymphocyte count of 12,500 on admission. this trended down throughout the hospitalization and no infectious etiology was
