A nurse in a prenatal clinic is reinforcing teaching with a client about a nonstress test. Which of the following statements should the nurse Include?

A. "A nurse will insert an IV prior to starting the test.": A nonstress test (NST) is noninvasive and does not require intravenous access. IV insertion is unnecessary unless other procedures or interventions are planned concurrently, so this statement is inaccurate for routine NST preparation. B. "You should have nothing to eat or drink for 4 hours prior to the test.": Fasting is not required for an NST. In fact, eating can stimulate fetal activity, which may improve the accuracy of the test by eliciting heart rate accelerations in response to movement. C. "You should expect the test to take a minimum of 2 hours.": A typical NST usually takes 20–40 minutes to complete, depending on fetal activity. Expecting a minimum of 2 hours may unnecessarily alarm the client and does not reflect standard test duration. D. "You will be asked to press a button when you feel your baby move.": During an NST, the client uses an event marker to indicate fetal movements. This helps correlate accelerations in the fetal heart rate with fetal activity, providing important information about fetal well-being and autonomic function.
