A 30-year-old woman presents with the acute onset of fever, pleuritic chest pain, and a productive cough. The patient's history is unremarkable except for recurrent cystitis for which she takes trimethoprim-sulfamethoxazole. She smokes cigarettes. On physical examination her temperature is 40 °C (104 °F), pulse rate is 120/min, respiration rate is 36/min, and blood pressure is 130/80 mm Hg. Abnormalities are localized to the right lung where crackles, rhonchi, and egophony are heard. Oxygen saturation is 85% by pulse oximetry. Chest radiograph shows a right lower lobe pneumonia. Sputum Gram stain is purulent with few epithelial cells and a predominance of gram-positive diplococci.

Which of the following antimicrobial agents would be the best initial therapy for this patient?

Ciprofloxacin
Vancomycin
Trimethoprim-sulfamethoxazole

Ciprofloxacin

gram positive diplococci suggest S.pneumonia. flouroquinones are bactericidal and act against both gram positives and gram negatives

it may be cipro.
but why not ceftriaxone?
ceftazidime should not be the answer.
regards.

ceftriaxone is a third gen cephalosporin and they do not act against gram positive organisms and the history is sugesstive of a community acqiured infection where s.pneumo is the commenest org.
