Pharmacological and Parenteral TherapiesQuestion 1064 of 2368

A client at 36 weeks of gestation has a positive group B streptococcus culture. Why is antibiotic treatment planned during labor instead of now?

  1. Antibiotics given before 40 weeks of gestation are unsafe for the fetus.
  2. The bacteria can recolonize the vagina before birth if treated earlier.
  3. The bacteria only begin to grow after the membranes rupture in labor.
  4. Antibiotics given earlier would harm the fetal lungs and affect breathing.
Show answer

Correct answer: The bacteria can recolonize the vagina before birth if treated earlier.

Treatment is delayed until labor because group B streptococcus can recolonize in the vagina when treated before birth.
