The pain is worse while chewing. The patient has hypertension and coronary artery disease. Her current medications include enalapril, metoprolol, aspirin, clopidogrel, simvastatin, and a multivitamin. She does not smoke or drink alcohol. Her temperature is 38.1C 100.5F, pulse is 72min, respirations are 16min, and blood pressure is 12886 mm Hg. Examination shows swelling and tenderness of the left parotid gland. Intraoral examination shows erythema with scant purulent drainage. Which of the following is the most appropriate next step in management?? A: Perform salivary duct dilation, B: Parotidectomy, C: Obtain a parotid biopsy, D: Administer nafcillin and metronidazole, E: Administer vancomycin and meropenemn,  <response>: This is a clinical vignette describing a patient who recently underwent a percutaneous coronary intervention and now presents with left-sided facial swelling and pain that is worse with chewing. This suggests parotitis. The description of erythema and purulent drainage in the oral cavity indicates infection rather than obstruction. The patient is febrile, indicating infection rather than inflammation. The most likely cause is infection of the parotid gland, known as suppurative parotitis. The choices describe various diagnostic and therapeutic options. Choice A of salivary duct dilation would be appropriate for obstruction but not infection. Choice B of parotidectomy would be overly aggressive initial management. Choice C of biopsy could be useful diagnostically after initial treatment failure but is not the immediate next step. Choices D and E describe reasonable antibiotic options, with D being narrower spectrum.D: Administer nafcillin and metronidazole
