E) Nothing; he likely has a viral infection
This patient's presentation is most consistent with a viral upper respiratory infection, and antibiotics are not indicated.
Clinical Reasoning
The patient presents with several features that strongly suggest a viral etiology rather than bacterial pharyngitis:
- Profuse nasal discharge (coryza)
- Cough due to postnasal drip
- Absence of cervical lymphadenopathy
- Low-grade fever (37.3°C is barely elevated)
While he does have erythematous tonsils with exudate, the presence of prominent upper respiratory symptoms (nasal discharge and cough) makes viral infection far more likely 1, 2.
Risk Stratification Using Clinical Scores
When evaluating for Group A beta-hemolytic streptococcal (GABHS) pharyngitis, clinical scoring systems help determine the need for testing or treatment 3, 1, 2:
Modified Centor Score criteria:
- Tonsillar exudates: +1
- Tender anterior cervical adenopathy: 0 (absent)
- Fever >38°C: 0 (temperature is 37.3°C)
- Absence of cough: 0 (cough is present)
This patient scores 1 point maximum, placing him at low risk for GABHS pharyngitis. At this score, neither testing nor antibiotics are indicated 3, 2, 4.
Key Clinical Features Against Bacterial Pharyngitis
The presence of cough, coryza (nasal discharge), and absence of significant fever or cervical lymphadenopathy are more characteristic of viral pharyngitis 1. These features actively argue against streptococcal infection, even in the presence of tonsillar exudate.
Management Approach
Symptomatic treatment is appropriate:
- NSAIDs (ibuprofen or naproxen) are more effective than acetaminophen for pain and fever control 3, 2
- The illness is typically self-limiting with a mean duration of 7 days 3
- Patient education about the viral nature and expected course is essential
Why Other Options Are Incorrect
Options A, B, and C (testing or treating for streptococcal pharyngitis): The clinical presentation with prominent upper respiratory symptoms and low Centor score makes bacterial pharyngitis unlikely. Testing would lead to unnecessary antibiotic use 3, 2, 4
Option D (immediate cephalosporin): Empiric antibiotics without appropriate risk stratification or testing would be inappropriate and contribute to antibiotic resistance. Even when antibiotics are indicated, penicillin (not cephalosporins) is first-line 1, 2
Common Pitfall to Avoid
Do not be misled by the presence of tonsillar exudate alone. Exudates can occur with viral infections, and the overall clinical picture—particularly the presence of cough and nasal discharge—is more important for distinguishing viral from bacterial causes 1, 2.
