A client is requesting information from a nurse about a nitrazine test. Which of the following statements should the nurse make?

A. "The test will determine if there is leaking amniotic fluid.": The nitrazine test is used to detect the presence of amniotic fluid in the vagina by measuring pH. A positive result indicates a more alkaline pH, suggesting rupture of membranes. This explanation accurately describes the purpose of the test to the client. B. "Your bladder should be full prior to me performing this test.": A full bladder is not required for a nitrazine test. In fact, urine can interfere with results because it is acidic and may cause a false-negative reading, so the bladder should not influence the test outcome. C. "I will be taking a blood sample to test for changes in your hormone levels.": The nitrazine test does not involve blood samples and is unrelated to hormone levels. It is performed using vaginal fluid to detect amniotic fluid, so this statement is inaccurate. D. "If this test is positive you will be required to have a non-stress test.": A positive nitrazine test indicates ruptured membranes, which may require further assessment, but it does not automatically mandate a non-stress test. Additional evaluation and clinical judgment guide next steps rather than an automatic NST.
