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: the patient is a 44 year old female with a history of left lower quadrant pain extensively worked up in the past with work-up negative, and recent oral surgery, who presents in her usual state of health until the a.m. of admission when she was attempting to unclog her toilet with sulfuric acid. by report, the patient presented to complaining of shortness of breath. o2 saturation was noted to be 89 to 90% on 100% nonrebreather. the patient was intubated secondary to airway protection. during intubation, medical staff at outside hospital noted vocal cord edema and inability to pass #7 et tube; instead a #6 was used. the patient was stable and transported to the . in the emergency department, the patient had an arterial blood gas of 7.37/42/357, on 100% fio2. the patient was vented on ac with total volume of 600, respiratory rate of 12.0 and peep of 5. the et tube was advanced 3 cm and an air leak was noted by the emergency department staff. the patient was then transferred to the funard intensive care unit. upon arrival, the patient was awake, placed on pressor support with a peep of 5, pulling and total volume was about 450, and saturation of 100% on 40% fio2. air leak was again noted. on review of systems, the patient denies nausea, vomiting, chest pain, shortness of breath, or abdominal pain. past medical history: 1. status post tooth extraction. 2. questionable history of depression. medications: it is unclear if the patient is on an anti-depressant. allergies: amoxicillin. family history: mother who died of breast cancer. father who died of diabetes mellitus and coronary artery disease. social history: the patient denies etoh use. has a six pack year history. denies intravenous drug use. the patient is separated and has three children. physical examination: temperature is 97.3 f.; blood pressure 153/99; heart rate 105, respiratory rate 12 to 16, and o2 saturation of 100% on fio2 of 40%. in general, the patient is alert with occasional somnolence. heent: extraocular muscles are intact. pupils equal and reactive. no lymphadenopathy. neck with no jugular venous distention. cardiac: regular rate and rhythm, normal s1 and s2. no murmurs, rubs or gallops. respiratory: clear to auscultation bilaterally. good air movement, no wheezes. abdomen soft, nontender, nondistended. positive bowel sounds. extremities with no cyanosis, clubbing or edema. laboratory: white blood cell count 4.7, hematocrit 37.9, platelets 265, pt and ptt, inr within normal limits. chem-7 unremarkable. toxicology screen of serum was negative. urine toxicology negative except for benzodiazepines, which the patient was given at outside hospital. urinalysis specific gravity greater than 1.030, small blood, no nitrites, no protein, negative leukocytes, positive ketones. no bilirubin. ph is 5.5; 11 to 20 epithelial cells were seen on sedimentation. arterial blood gas is 7.37, 42, 357, on ac/600/12/5/100%. ekg sinus tachycardia at 100 beats per minute. no specific st-t wave changes. normal intervals. normal axis. chest x-ray with et tube 6 cm above carina before it was advanced 3 cm. possible bibasilar atelectasis. hospital course: in summary, this is a 44 year old female with exposure to sulfuric acid, intubated for airway protection secondary to reported vocal cord edema. 1. questionable vocal cord/tracheal edema, by report from outside hospital. edema was noted prior to intubation and was thought to be secondary to exposure to sulfuric acid resulting in a chemical pneumonitis. the patient was intubated overnight for concern of increased swelling. ent was consulted and recommended at least 24 hour intubation since vocal cord edema can worsen 24 hours post-exposure. the patient was sedated with ativan and p.r.n. boluses of fentanyl. the patient was not started on any intravenous steroids. the patient's ventilator settings were changed to pressure support of 10 and peep of 5. there was no evidence for pneumonia on chest x-ray and the patient had a normal white blood cell count. chest x-ray was reported in the a.m. after admission. no antibiotics were started. the patient was extubated on , however, was kept in-house overnight for continued observation. the patient's o2 saturation was initially only 90% but rose to 94 to 95% prior to discharge. post-extubation, racemic epinephrine was kept at the bed side, but was not needed to be used. after extubation, the patient did complain of some throat pain and soreness which was to be expected secondary to intubation. these symptoms improved prior to discharge. 2. fluids, electrolytes and nutrition: the patient was maintained on d5 normal saline at 125 cc an hour. the patient was continued to be kept npo shortly after extubation to avoid aspiration. 3. prophylaxis: the patient was continued on protonix and venodyne for gi and deep venous thrombosis prophylaxis. after the patient's respiratory status was stable, the patient was discharged directly to home and to be followed up as an outpatient by her primary care physician, . , on . discharge diagnoses: 1. vocal cord edema secondary to sulfuric acid exposure. condition at discharge: stable to home. discharge medications: same as admission medications; no new medications were added. , m.d. dictated by: medquist36 procedure: non-invasive mechanical ventilation diagnoses: anemia, unspecified tachycardia, unspecified bronchitis and pneumonitis due to fumes and vapors accidental poisoning by acids not elsewhere classified 

Answer: The patient is high likely exposed to
