eradication therapy was begun on . she had an additional drop in her hematocrit 1 day after her egd, and she was transfused an additional 2u prbc. she was taken for another egd on which showed stable non-bleeding duodenal ulcer. thereafter her hematocrit was stable with a discharge value of 25.3% 2. pneumonia: initially presented with leukocytosis. cxr revealed rll infiltrate which was suspicious for a pneumonia. she was treated with 1 week of levofloxacin 250mg; the course was completed on . 3. demential/delerium: prior discharge summary from documented known dementia. she appeared to have fairly advanced dementia and was not oriented to her surroundings or to time. a head ct showed a chronic sdh vs. hygroma with no active issue. she was started on standing haldol with olanzapine prn; a sitter was used in the icu but was not needed towards the end of the patient's floor stay. 4. renal failure: cr baseline in the 2s per a discharge summary from . scr fluctuated during the stay. urine output remained >600cc/day, but the patient needed reminders to continue taking po. she will likey need outpatient renal follow-up for epo therapy, vitamin d, calcium and phos monitoring and for possible discussions of dialysis given that she has stage v ckd. medications on admission: 1. lantus 6 u qhs, novalog ss 2. asa 81 mg daily 3. labetolol 400 mg 4. hydralazine 50 mg qid 5. nifedipine xl 90 mg daily 6. clonidine 0.3 mg patch - 2 patches qwed 7. ranitidine 150 mg daily 8. mirtazipine 15 mg qhs 9. bisacodyl 10 mg prn daily prn 10. mom prn 11. 100 mg 12. tylenol prn 13. fe sulfate 325 mg daily 14. mvi daily discharge medications: 1. mirtazapine 15 mg tablet : one (1) tablet po hs (at bedtime). 2. hydralazine 50 mg tablet : one (1) tablet po q6h (every 6 hours). 3. labetalol 200 mg tablet : two (2) tablet po bid (2 times a day). 4. docusate sodium 100 mg capsule : one (1) capsule po bid (2 times a day). 5. senna 8.6 mg tablet : one (1) tablet po bid (2 times a day). 6. ferrous sulfate 325 (65) mg tablet : one (1) tablet po once a day. 7. multi-vitamin tablet : one (1) tablet po once a day. 8. lansoprazole 30 mg tablet,rapid dissolve, dr : one (1) tablet,rapid dissolve, dr po bid (2 times a day). 9. haloperidol 5 mg tablet : one (1) tablet po q6pm (). 10. nifedipine 90 mg tablet sustained release : one (1) tablet sustained release po daily (daily). 11. acetaminophen 325 mg tablet : 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. 12. insulin regular human 300 unit/3 ml insulin pen : as per attached sliding scale units subcutaneous three times a day. 13. amoxicillin 250 mg capsule : two (2) capsule po q24h (every 24 hours) for 11 days. 14. olanzapine 5 mg tablet, rapid dissolve : one (1) tablet, rapid dissolve po qhs (once a day (at bedtime)) as needed for agitation. 15. clarithromycin 250 mg tablet : one (1) tablet po q12h (every 12 hours) for 12 days: 11 days plus pm dose on . discharge disposition: extended care facility: - discharge diagnosis: primary: 1. upper gastrointestinal bleed, likey from duodenal ulcer 2. anemia, acute blood loss 3. helicobacter pylori postive 4. pneumonia, community acquired 5. delirium secondary: 1. right cerebral hemispheric chronic subdural hematoma 2. chronic kidney disease stage v 3. diabetes mellitus type ii 4. hypertension discharge condition: hemodynamically stable with stable hematocrit. discharge instructions: you were admitted with gastrointestinal bleeding from a duodenal ulcer and pneumonia. please continue to take lansoprazole twice daily until told to stop by a doctor. please avoid taking anti-inflammatory medications (aleve, advil, ibuprofen, motrin) as this may exacerbate your ulcer. the most likely cause of your ulcer was infection with h.pylori. given this, you are to be treated with antibiotics for a total of 2 weeks. please be sure to take this, as prescribed. if you develop shortness of breath, fever, bloody stool, abdominal pain, nausea, vomiting, or any other concerning symptoms, please contact your doctor or report to the nearest er. in addition, given your poor kidney function, you should be sure to follow-up with a nephrologist (kidney doctor). followup instructions: please contact dr. to schedule a follow up appointment after discharge. procedure: venous catheterization, not elsewhere classified other endoscopy of small intestine endoscopic control of gastric or duodenal bleeding transfusion of packed cells diagnoses: pneumonia, organism unspecified chronic kidney disease, stage v acute posthemorrhagic anemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled other persistent mental disorders due to conditions classified elsewhere hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease chronic or unspecified duodenal ulcer with hemorrhage, without mention of obstruction hyperosmolality and/or hypernatremia helicobacter pylori [h. pylori]
