A nurse is caring for a client who is at 37 weeks of gestation and is being tested for group B streptococcus ß-hemolytic (GBS). The client is multigravida and multipara with no history of GBS. She asks the nurse why the test was not conducted earlier in her pregnancy. Which of the following is an appropriate response by the nurse?
Correct answer
D
Rationale
Rationale: Answer D is correct because testing for GBS at 37 weeks ensures detection of any recent colonization, which can change rapidly. Testing earlier in pregnancy may not accurately reflect GBS status at the time of delivery. Answers A, B, and C are incorrect because the focus should be on current GBS status, not past symptoms or test results. The nurse should prioritize testing closer to delivery for accurate results.
