A primary care physician is reviewing the charts of four outpatients who presented with acute infectious or inflammatory symptoms. Match each patient's clinical presentation with the most appropriate, guideline-concordant initial management strategy to optimize antimicrobial stewardship and patient outcomes.
- A 42-year-old man with 4 days of purulent nasal discharge, nasal congestion, and facial pressure without fever.Provide symptomatic therapy only; antimicrobial therapy is not indicated.
- A 68-year-old man with a history of severe chronic obstructive pulmonary disease who reports a 2-day history of increased dyspnea, increased cough, and newly purulent sputum.Prescribe a short course of an oral macrolide or tetracycline, along with bronchodilators and systemic corticosteroids.
- A 24-year-old healthy woman with 2 days of dysuria, urinary frequency, and suprapubic tenderness, without fever or costovertebral angle tenderness.Prescribe a short course of oral nitrofurantoin or trimethoprim-sulfamethoxazole.
- A 19-year-old man with a 2-day history of fever to , tonsillar exudates, tender cervical lymphadenopathy, no cough, and a positive rapid antigen detection test for streptococcus.Prescribe a 10-day course of oral penicillin V or amoxicillin.
Answer
The patient with 4 days of sinus symptoms requires symptomatic therapy only. The patient with a COPD exacerbation requires a macrolide or tetracycline. The patient with uncomplicated cystitis requires nitrofurantoin or trimethoprim-sulfamethoxazole. The patient with confirmed streptococcal pharyngitis requires penicillin V or amoxicillin.
Appropriate antimicrobial stewardship involves targeting true bacterial infections while avoiding antibiotics for viral or self-limiting conditions. The patient with 4 days of sinus symptoms likely has a viral infection and needs symptomatic care. The patient with a COPD exacerbation showing purulent sputum and increased dyspnea meets the criteria for antibiotics (e.g., macrolides) to reduce failure rates. The young woman has uncomplicated cystitis, effectively treated with a short course of nitrofurantoin. The young man has confirmed Group A streptococcal pharyngitis, requiring a 10-day course of beta-lactam therapy to eradicate the organism and prevent acute rheumatic fever.
