A: Intravenous amphotericin B, B: Oral amoxicillin-clavulanic acid, C: Oral levofloxacin, D: Reassurance and follow-up in 1 week, E: Oral loratadine,  <response>: This is a clinical case scenario describing a 43-year-old man with symptoms of nasal congestion, fatigue, fevers, facial pain, and purulent nasal discharge for 12 days. He has a history of type 2 diabetes and hypertension. On exam, he has purulent nasal discharge, pharyngitis, left maxillary sinus tenderness, fever, and elevated ESR. Based on the chronicity, symptoms, and exam findings, this patient most likely has acute bacterial sinusitis. The most appropriate next step would be to start him on antibiotic therapy to cover common sinusitis pathogens. Choice A, intravenous amphotericin B, is an antifungal medication and would not be indicated in this presumed bacterial infection. Choice B, oral amoxicillin-clavulanic acid, is a reasonable antibiotic option for acute bacterial sinusitis. This would be an appropriate treatment choice.Choice C, oral levofloxacin, is also a reasonable antibiotic option for acute sinusitis. This would be an appropriate treatment choice. Choice D, reassurance and follow up, would not be appropriate as the patient likely needs antibiotic therapy. Choice E, oral loratadine, is an antihistamine and would not treat the underlying presumed bacterial infection.B: Oral amoxicillin-clavulanic acid
