Which assessment would the nurse perform to validate that the membranes are ruptured?
参考答案: B
参考解析: The nitrazine test determines whether the client's membranes have ruptured. The nurse performs a sterile vaginal examination, inserts the nitrazine test tape, then assesses the tape for a color change. If the membranes are ruptured, the tape becomes bluish, which indicates that the vaginal environment is alkaline. If the test tape remains yellow or green, the vaginal environment is acidic, indicating that the membranes aren't ruptured.
