Identifying Abnormal Fetal Heart Rate

During a routine evaluation of a laboring patient in the active phase, the nurse notes that the fetal heart rate (FHR) monitoring shows a baseline FHR of 150 bpm with periodic decelerations. The patient's cervix is dilated to 7 cm, and contractions are occurring every 2-3 minutes, lasting about 60 seconds. The nurse prepares for potential complications.

According to the guidelines for identifying fetal distress, the nurse should recognize that a fetal heart rate of _______ bpm is considered an abnormal finding if it persists and is associated with other signs of distress.
