Correct answer: C — Nitrofurantoin for 5-7 days

Asymptomatic bacteriuria in pregnancy should be treated; nitrofurantoin for 5-7 days is appropriate (avoid near term). Untreated asymptomatic bacteriuria increases the risk of pyelonephritis. TMP-SMX should be avoided in the first trimester if alternatives exist. Fluoroquinolones should be avoided. Single-dose fosfomycin is an acceptable alternative and is not contraindicated.
