15 Fetal Assessment During Labor

K E Y P O I N T S• Because labor is a period of physiologic stress for the fetus, fre-

quent monitoring of fetal status is part of the nursing care during labor. The fetal oxygen supply must be maintained during labor to prevent fetal compromise and promote newborn health after birth.

• The goals of intrapartum FHR monitoring are to identify and differentiate the normal (reassuring) patterns from the abnormal (nonreassuring) patterns, which can indicate fetal compromise.

• Fetal well-being during labor is gauged by the response of the FHR to UCs.

• Standardized definitions for many common FHR patterns have been adopted for use in clinical practice by the ACNM, ACOG, and AWHONN.

• The monitoring of fetal well-being includes FHR and UA assess-ment and assessment of maternal vital signs.

• Intermittent auscultation (IA) involves listening to fetal heart sounds at periodic intervals to assess the FHR.
