Can the licensed practical nurse perform a fetal non-stress test (NST) and an amniotic fluid index level using ultrasound?

It is within the scope of an appropriately prepared and competent licensed practical nurse to perform a fetal NST and amniotic fluid index level using ultrasound under the direction of an authorized health care practitioner, or under the direction and supervision of the registered nurse, following clinical practice standards. The licensed practical nurse should use the Scope of Practice Decision Tree to determine if these activities are within the nurse's legal and individual scope of practice.
