Which outpatient CAP option is listed that is a tetracycline?

• A. Doxycycline
• B. Amoxicillin
• C. Macrolide
• D. Fluoroquinolone

Answer: (A)

Identifying the tetracycline among outpatient CAP options. Doxycycline is a tetracycline antibiotic that works by binding the 30S ribosomal subunit to block protein synthesis. It’s used orally for community-acquired pneumonia to cover typical and atypical pathogens, making it a suitable outpatient choice. The other options are different classes: amoxicillin is a beta-lactam that inhibits cell wall synthesis; macrolides inhibit the 50S ribosomal subunit; fluoroquinolones inhibit DNA gyrase and topoisomerase. Therefore, the tetracycline listed is doxycycline.
