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 87-year-old woman with history of copd who presents with decreased mental status, mumbling, anorexia, and dyspnea for the last 2-3 days. in the patient was admitted to the micu for copd exacerbation and pneumonia, intubated for respiratory failure times 24 hours, given levaquin and steroids and then discharged on . she was recently readmitted to the micu on with an abg of 7.18, pco2 122, po2 217 on non invasive ventilation with improvement in mental status and abg to 7.4/63/56. her hypercarbia was thought to be secondary to opioids and benzos. she was not given steroids during that admission. now patient presents with decreasing mental status, mumbling, anorexia and dyspnea times 2-3 days. no fevers, chills, nausea, vomiting, chest pain, palpitations, abdominal pain or cough. the patient arrived by ambulance from home, was somnolent but arousable to verbal stimuli. her vital signs on admission, temperature 98.8, blood pressure 126/34, pulse 91, respiratory rate 30 and o2 sats of 75% on room air, with increasing to 93% on four liters of oxygen. her abg at that time was ph 7.22, pco2 95, po2 85 on four liters of oxygen. bi-pap ventilation was initiated with increase in sats to 93 to 97%. she was more awake with the bi-pap ventilation. her next gas showed improvement with ph 7.24, pco2 87 and po2 of 62. upon initial presentation to the micu her white blood cell count was 20.4 and subsequently she was given one dose of levaquin. she was hydrated with d5 normal saline. upon stabilization of her respiratory status, she was transferred to the service on . past medical history: copd, on home o2 2-3 liters for last four years. adenocarcinoma of the rectum, status post resection, lar . lower back pain. osteoarthritis. anxiety. migraine headaches. siadh. osteoporosis. old lacunar infarct in the right coronary radiata. allergies: doxycycline. medications: on admission, albuterol 2 puffs , atrovent 2 puffs tid, ritalin 5 mg q day, colace 100 mg po bid, zantac 150 mg po bid, klonopin 0.5 mg , darvon 65 mg po q 6 hours prn, megace 40 mg/ml 1 tsp qid, serevent 2 puffs . social history: the patient is divorced, lives with her two sons at home. history of tobacco use, quit 20 years ago, prior to that 40 pack year history. no ethanol, no iv drug use, no exercise. physical examination: on transfer to service, temperature 97.4, pulse 82, blood pressure 138/60, respiratory rate 18, o2 saturation 97% on 35% venti mask. general, alert and oriented times two, no apparent distress. pulmonary, decreased breath sounds bilaterally, no wheezes or crackles. cardiovascular, regular rate and rhythm, s1 and s2. abdomen, nontender, non distended, positive bowel sounds, soft. extremities, no cyanosis, erythema or edema. laboratory data: white blood cell count 12.6, hematocrit 33.6, platelet count 291,000, sodium 132, potassium 4.8, chloride 31, co2 36, bun 27, creatinine 0.6, glucose 141, calcium 8.4, phosphorus 2.6, magnesium 1.9. hospital course: 1. pulmonary: through the rest of her course on the firm the patient's pulmonary status remained stable. she did not require any bi-pap at night and her o2 requirements slowly decreased to baseline level of liters. her o2 saturation at time of discharge was 93% on two liters of oxygen. the patient's respiratory decompensation was thought to be secondary to excessive benzodiazepines, narcotics on top of her underlying copd. the patient's white blood cell count decreased over the course of her stay in the hospital. since there was no radiographic evidence of pneumonia, the patient was not continued on antibiotics. no steroids were initiated. 2. infectious disease: the patient's white blood cell count decreased over the course of her stay in the hospital. the patient remained afebrile throughout the course of her stay in the hospital. the patient had femoral line placed in her femoral vein. initial sets of blood cultures drawn through the femoral line grew coagulase negative staphylococcus and corynebacterium. subsequently the femoral line was removed and the tip was sent for culture. the tip culture also grew coagulase negative staphylococcus and corynebacterium. prior to starting vancomycin, two surveillance cultures were drawn peripherally. the patient was started on vancomycin for empiric treatment. the surveillance cultures remained negative at time of discharge and subsequently the vancomycin was stopped. the patient remained afebrile throughout the course of her stay in the hospital. the patient's white blood cell count trended down through her course in the hospital. 3. gi: the patient's hematocrit remained stable throughout her course of stay in the hospital. her stool was guaiac positive. given her history of rectal carcinoma, she will need a follow-up colonoscopy as an outpatient. she remained hemodynamically stable throughout the course of her stay in the hospital. 4. neuro: the patient's mental status improved with improvement in her respiratory status. the change in mental status that brought her to the hospital was likely secondary to her hypercarbic respiratory distress. discharge diagnosis: 1. hypercarbic respiratory failure secondary to benzodiazepine and narcotic use. discharge medications: atrovent mdi 2 puffs tid, serevent mdi 2 puffs , albuterol mdi 2 puffs q 4-6 hours prn, tylenol prn, zantac 150 mg po bid, colace 100 mg po bid, ritalin 5 mg po q day, megace 40 mg/ml, 1 tsp qid. discharge condition: fair. discharged to home with skilled nursing and vna, home pt. patient to follow-up with pcp, . . , m.d. dictated by: medquist36 procedure: non-invasive mechanical ventilation diagnoses: acute kidney failure, unspecified chronic airway obstruction, not elsewhere classified poisoning by opium (alkaloids), unspecified poisoning by benzodiazepine-based tranquilizers accidental poisoning by other opiates and related narcotics accidental poisoning by benzodiazepine-based tranquilizers anxiety state, unspecified acute respiratory failure 

Answer: The patient is high likely exposed to
