the patient was not discharged on aspirin and vioxx, however, she was also kept without nonsteroidal anti-inflammatory drugs throughout this visit. she underwent endoscopy which showed - tear near the gastroesophageal junction. there were erosions in the antrum. there was an ulcer in the lesser curvature of the stomach with a visible vessel which was cauterized. the patient was transfused a total of one unit of packed red blood cells. her hematocrit initially was 24.1 on admission and at the time of this dictation, her hematocrit remained stable at 29.8%. there were no other signs of active bleeding. hematocrit was checked serially, all which were stable. the patient will be continued on protonix 40 mg p.o. twice a day until , at which time she can be switched over to protonix 40 mg once daily. the patient was initially kept npo while she was having the bleeding, however, after that stabilized, she was continued on a regular diet. there were no other issues. 2. coronary artery disease - secondary to her gastrointestinal bleeding, her aspirin was held. the patient was initially on telemetry but was in normal sinus rhythm at which time it was discontinued. 3. neurology - the patient complains of a headache at which time she underwent a head ct on , which showed no evidence of subacute hemorrhage and findings consistent with sinusitis. please see the infectious disease section of this discharge summary. there were no other neurological symptoms or signs. the patient was moving all extremities without any difficulties. 4. infectious disease - because of her head ct which showed sinusitis and headache, the patient was started on amoxicillin one gram p.o. twice a day which will be continued for a total of 14 days as well as clarithromycin 500 mg p.o. twice a day for a total of ten days. there were no other infectious disease issues. 5. depression - this remained stable. the patient was kept on her zoloft 50 mg once daily. 6. osteoporosis - this remained stable. the patient was to continue os-cal and vitamin d. 7. hypertension - the patient's blood pressure remained stable. secondary to her decreased blood pressure, she was not kept on her norvasc 2.5 mg once daily. this will be added on when blood pressure remains stable. 8. code status - dnr/dni. discharge diagnoses: 1. dementia. 2. upper gastrointestinal bleed, status post cauterization of a bleeding vessel. 3. gastroesophageal reflux disease. 4. osteoporosis. 5. cataracts. 6. vertigo. 7. gait disorder. 8. hypertension. 9. hematuria. 10. coronary artery disease. medications on discharge: 1. calcitonin 200 international units subcutaneously once daily. 2. vitamin d 400 units p.o. once daily. 3. calcium carbonate 500 mg p.o. three times a day. 4. tylenol p.r.n. 5. colace 100 mg p.o. twice a day. 6. protonix 40 mg p.o. twice a day and this will be changed to a once daily dosing after , if there are no signs or symptoms of gastrointestinal problems. 7. sulfate 325 mg p.o. twice a day. 8. amoxicillin one gram p.o. twice a day times a total of ten more days. 9. clarithromycin 500 mg p.o. twice a day for a total of ten more days. 10. sertraline 50 mg once daily. 11. dextromethorphan polycomplex 10cc q12hours p.r.n. 12. risperdal 0.5 mg p.o. twice a day p.r.n. follow-up: 1. the patient will need to follow-up with her primary care physician within week. 2. will need to follow-up with gastroenterology as needed basis. , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine endoscopic control of gastric or duodenal bleeding diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension acute posthemorrhagic anemia other persistent mental disorders due to conditions classified elsewhere osteoporosis, unspecified chronic or unspecified gastric ulcer with hemorrhage, without mention of obstruction gastroesophageal laceration-hemorrhage syndrome unspecified sinusitis (chronic)
