A nurse is caring for a client who is at 37 weeks of gestation and reports a slow trickle of vaginal fluid for the past 12 hr. Which of the following diagnostic tests should the nurse anticipate?

A. Fetal fibronectin testing is used to assess risk for preterm labor, not to confirm rupture of membranes. B. Amniocentesis for fetal lung maturity is generally not needed at 37 weeks or later. C. Urinalysis is for urinary tract issues, not for detecting amniotic fluid. D. Nitrazine testing helps determine if vaginal fluid is amniotic fluid by assessing pH, aiding in diagnosing rupture of membranes.
