Final answer:
The recommended treatment for a patient with a history of recent travel who presents with pneumonia, confusion, ataxia, or diarrhea is azithromycin.
Step-by-step explanation:
The recommended treatment for a patient with a history of recent travel who presents with pneumonia, confusion, ataxia, or diarrhea is **azithromycin**. Azithromycin is a first-line antibiotic that is effective against a wide range of bacterial pathogens. Other options such as ciprofloxacin, doxycycline, and trimethoprim-sulfamethoxazole (TMP-SMX) may also be used depending on the specific pathogen and its susceptibility. It is important to consider the patient's history, travel destinations, and any other relevant factors in determining the most appropriate treatment.
