This is a multiple step Q
D. The first step in the approach to this patient with a community-acquired pneumonia is to categorize her condition according to the American Thoracic Society guidelines (1993), which are based on severity of illness, age, comorbidities, and the need for hospitalization. This patient does not meet the criteria for hospitalization (one of the following is needed: respiratory rate > 30 breaths/min, room air PaO2< 60 mm Hg, O2 saturation less than 90% on room air, or bilateral or multiple lobes involved), and she is younger than 60 years without any comorbidities. The most common organisms are Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydia pneumoniae, Haemophilus influenzae, Legionella, and respiratory viruses. Recommended treatment is with erythromycin or a related macrolide, such as azithromycin or clarithromycin.
Amoxicillin (choice A) does not have broad enough coverage to include the organisms listed above.
Ceftriaxone (choice C) and ampicillin-sulbactam (choice B) are used for hospitalized patients with community-acquired pneumonia.
Erythromycin plus ceftriaxone (choice E) is reserved for patients who are severely ill and hospitalized.
