Ciprofloxacin would be the appropriate first-line antibiotic choice
Step-by-step explanation:
Ciprofloxacin are fluoroquinolones which belong to broad-spectrum antibiotics used to treat many bacterial infections especially of the gastrointestinal and urinary tracts, eye, ear, skin, etc.
Ciprofloxacin is considered as the first line of antibiotic in most of the uncomplicated urinary tract infections, like in the above case, Jamie is afebrile and healthy but with sulfa allergy.
Since she is allergic to sulfa drugs, antibiotics containing sulfa like azithromycin or ceftrioxone should not be prescribed for Jamie as they may cause skin rash hives or irritation, eye itching, and other allergic reactions.
