Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this is an 82-year-old male with a past medical history significant for alzheimer's dementia, hypertension, who presented to the emergency department on after worsening cough and shortness of breath x1 day. he had a cough that was productive of white sputum. there were no fevers, chills, nausea, vomiting, or chest pain according to the emergency department records. in the emergency department, the patient was tachypneic with a respiratory rate in the 40s-50s, 84% on 15 liters, which went to 89% on 100% nonrebreather. the chest x-ray was significant for bilateral lower lobe infiltrates. at that point, the patient was intubated, given ceftriaxone, clindamycin, and nebulizer, and was admitted to the fenard intensive care unit on the . according to the emergency department report, the patient was brought to the emergency department by caregiver, who left at that time. attempts were made to call the family, and the pcp was also attempted to be contact at that time. past medical history: 1. alzheimer's dementia. 2. hypertension. 3. history of a right cerebellar hemorrhage. 4. history of colonic adenoma. 5. benign prostatic hypertrophy. social history: lives in an assisted-living facility, caregiver l. . next of listed as , his cousin, . is also a health-care proxy. pcp is , . allergies: no known drug allergies. medications on admission: 1. hydralazine 75 mg . 2. lopressor 100 mg . 3. aricept 5 mg q hs. 4. labetalol 100 mg tid. 5. vitamin e. 6. colace. 7. aspirin 81 mg q day. physical exam on admission: temperature 101.0, blood pressure 115/49, heart rate 91, respiratory rate 15, and 100%. weight 82 kg. vent settings ac 600/12/0.60/5 with an arterial blood gas of 7.41/50/92. generally, he was intubated and sedated. heent: left pupil pinpoint, right regular and nonreactive bilaterally. the neck was with no jugular venous distention and no lymphadenopathy. lungs are clear to auscultation bilaterally anteriorly. cardiovascular: regular, rate, and rhythm with a holosystolic murmur in the left lower sternal border radiating to the apex. abdomen was soft, nontender, nondistended with active bowel sounds, no hepatosplenomegaly noted. extremities without edema, or warmth, with 2+ dp and pt pulses bilaterally. neurologic: withdraws to pain. laboratories: white count 8.0, neutrophils 78, lymphocytes 14, monocytes 5, eosinophils 3, hematocrit 44.1, platelets 245, mcv 89. sodium 139, potassium 5.2, chloride 99, bicarb 27, bun 19, creatinine 1.1, glucose of 106, anion gap of 13. pt 13, ptt 22.5, inr of 1.1. urinalysis was cloudy with a specific gravity of 1.020, large blood with 100 protein, greater than 50 red blood cells, 0-2 white blood cells, no epi's, no bacteria. urine culture is pending on admission. electrocardiogram: sinus tachycardia at 105, normal axis, and no acute changes. chest x-ray: bilateral lower lobe opacities, small bilateral effusions consistent with multi-focal pneumonia versus congestive heart failure. hospital course: the patient was admitted to the micu with hypoxic respiratory failure and bilateral infiltrates on chest x-ray. he was intubated and sedated, and he was initiated on treatment with levofloxacin and clindamycin for possible aspiration pneumonia. sputum cultures and blood cultures were obtained. he was hemodynamically stable and blood pressure medications were held. he had poor urine output initially, and was bolused. on antibiotics, the patient defervesced and the white count was stable. patient was also diuresed gently in order to aid future extubation. on , patient's antihypertensive lopressor and hydralazine were initiated, and they continued to monitor him for possible extubation. patient was extubated on the morning of , with sats in the low 90s on 4 liters nasal cannula. he had one episode of atrial fibrillation which started on , the hydralazine and lopressor were continued. the patient was rate controlled even on atrial fibrillation. the cultures that were sent were without growth as of , and the white count continued to decrease. he was continued on levofloxacin and clindamycin with a goal of total 14 day course. in light of the atrial fibrillation, anticoagulation was also considered at this time, but was decided against due to fall risk and history of cerebellar hemorrhage. patient was transferred to the floor from the intensive care unit on , was continued on intravenous antibiotics, and oxygen saturations were monitored. the patient was eventually weaned off 4 liters nasal cannula to about 1.5 while maintaining saturations in the 94-96% range. the course on the floor for the patient was relatively stable, though did have one evening of low urine output, but patient had poor po intake over the course of the day, and thus was given fluids to which he responded. laboratories drawn did not show evidence of acute renal failure. the bun and creatinine ratio was greater than 20, thus simply due to dehydration. the patient had a bed-side swallow evaluation performed in order to evaluate for over-aspiration in light of the multi-focal pneumonia. there was no overt evidence of aspiration of either thin liquids, thick liquids, or puree. recommendations included one-to-one sitting with aspiration precautions with patient sitting bold upright. it was determined that a video swallowing study would not be necessary to evaluate for silent aspiration. patient then received a physical therapy evaluation in order to facilitate nursing facility placement, so the patient would not receive subsequent care at the . the patient was discharged to on . discharge medications: 1. lansoprazole 30 mg po q day. 2. bisacodyl 10 mg pr prn. 3. clindamycin 300 mg po q8h x7 days for a 14 day course. 4. levofloxacin 250 mg po q day x7 days for a total 14 day course. 5. lisinopril 10 mg po q day with instructions to hold for a systolic blood pressure of less than 100. 6. the hydralazine was discontinued. 7. donepezil 5 mg po q hs. 8. heparin 5,000 units subq q12h. condition on discharge: improved. discharge status: to , health-care proxy, was in agreement with plan. discharge diagnoses: 1. alzheimer's dementia. 2. hypertension. 3. hypoxic respiratory failure secondary to aspiration multi-lobar pneumonia requiring intubation and intensive care unit stay. , m.d.
