She had a sore throat and nasal congestion the week before that had initially improved. Her temperature is 38.1C 100.6F. Physical exam shows purulent nasal drainage and tenderness to percussion over the frontal sinuses. The nasal turbinates are erythematous and mildly swollen. Which of the following describes the microbiological properties of the most likely causal organism?? A: Gram-negative, oxidase-positive, maltose-nonfermenting diplococci, B: Gram-positive, optochin-sensitive, lancet-shaped diplococci, C: Gram-negative, lactose-nonfermenting, blue-green pigment-producing bacilli, D: Gram-positive, coagulase-positive, clustered cocci, E: Gram-positive, anaerobic, non-acid fast branching filamentous bacilli,  <response>: This is a clinical vignette describing a 61-year-old woman with symptoms of fever, headache, cough, thick nasal discharge, sore throat, and nasal congestion suggestive of an upper respiratory tract infection. The description of purulent nasal drainage and tenderness over the frontal sinuses indicates likely sinusitis. The question asks about the microbiological properties of the most likely causal organism. Based on the clinical presentation of acute bacterial sinusitis, the most likely organism is Streptococcus pneumoniae. S. pneumoniae is a Gram-positive, lancet-shaped diplococcus that is optochin-sensitive. Choices A, C, and E describe properties inconsistent with S. pneumoniae. Choice D describes Staphylococcus aureus, which does not typically cause sinusitis.B: Gram-positive, optochin-sensitive, lancet-shaped diplococci
