الإجابة: B. Ciprofloxacin
Fever, flank pain, costovertebral angle tenderness and a positive urinalysis = acute pyelonephritis (E. coli most likely). The lecture's empiric therapy for acute UTI is oral TMP/SMX or oral ciprofloxacin, so ciprofloxacin is the answer here. Ertapenem is reserved for ESBL organisms, vancomycin has no gram-negative activity, and amoxicillin is not a listed UTI choice.

C
ليش غلط
Ertapenem is a carbapenem, the drug of choice for ESBL organisms. No ESBL is documented here (culture pending), so it is not needed empirically.

ليش غلط
Vancomycin covers gram-positive bacteria only (MRSA, strep, enterococcus) and has no activity against gram-negative bacteria such as E. coli.
