A 62-year-old female presents to a primary care clinic with a chief complaint of worsening nasal symptoms. She reports experiencing nasal congestion, rhinorrhea, and a persistent cough for the past twelve days, initially dismissing it as a common cold. However, over the last five days, her nasal discharge has become significantly thicker and greenish, accompanied by constant facial pressure and dull pain, particularly across her cheeks and forehead. She also notes a new onset of subjective fever and increased fatigue. Her medical history is significant for well-controlled type 2 diabetes mellitus, chronic obstructive pulmonary disease (COPD) due to a 40 pack-year smoking history, and occasional seasonal allergies. Her current medications include metformin and an inhaled corticosteroid/LABA combination. Her vital signs today are: temperature 38.9°C, blood pressure 138/88 mmHg, pulse 98/min, and respirations 18/min. On physical examination, she exhibits bilateral mucopurulent discharge in the nasal passages, with tenderness upon palpation over the maxillary and frontal sinuses. Her pharynx is mildly erythematous without exudates. Oral examination reveals some dental caries. Considering this presentation, what is the most likely diagnosis and the appropriate initial management strategy?

A 30-year-old woman with a known history of schizophrenia, currently adherent to her medication regimen, is admitted to the medical ward following an emergency department visit due to a new-onset generalized tonic-clonic seizure.
