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: discharge status: the patient is discharged to the . discharge diagnosis: 1. diastolic dysfunction. 2. hypercarbic respiratory arrest. 3. chronic obstructive pulmonary disease. 4. methicillin-resistant staphylococcus aureus pneumonia. discharge medications: 1. aspirin 325 mg p.o. q.d. 2. fluticasone two puffs b.i.d. 3. salmeterol 50 micrograms one inhalation q. 12 hours. 4. atorvostatin 10 mg p.o. q.d. 5. ipratropium bromide 0.02% one nebulizer q. six hours p.r.n. 6. prednisone 20 mg p.o. q.d. times two days, 10 mg p.o. q.d. times two days. 7. metoprolol 25 mg p.o. b.i.d. 8. vancomycin 1 gram iv q.d. times seven days. 9. heparin 5,000 units q. eight hours subcutaneously. 10. pantoprazole 40 mg p.o. q.d. 11. lasix 40 mg p.o. q.d. 12. calcium carbonate 500 mg p.o. t.i.d. follow-up: the patient is discharged to where he will continue on medications as prescribed. he will continue vancomycin for seven days for mrsa pneumonia. it is hoped at this time that he will also be placed on an ace inhibitor for his antihypertensive regimen. the patient will be followed by the physicians at the rehabilitation center. he is encouraged to contact dr. at hospital to schedule a follow-up appointment within two weeks of being discharged from . if dr. is not taking any new patients, the patient is welcome to follow-up with dr. in the clinic. , m.d. dictated by: medquist36 procedure: insertion of intercostal catheter for drainage continuous invasive mechanical ventilation for less than 96 consecutive hours continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified insertion of endotracheal tube insertion of endotracheal tube transfusion of packed cells diagnoses: congestive heart failure, unspecified acute kidney failure, unspecified obstructive chronic bronchitis with (acute) exacerbation pulmonary collapse acute respiratory failure pneumonitis due to inhalation of food or vomitus methicillin susceptible pneumonia due to staphylococcus aureus diastolic heart failure, unspecified 

Answer: The patient is high likely exposed to
