A nurse is assessing a client who is 8 hours postpartum.
Where should the nurse expect to find the fundus?

Choice A rationale

Spontaneous rupture of membranes (SROM) can sometimes be associated with variable decelerations due to potential cord compression if the presenting part is not well applied, but it is not the most likely cause of early decelerations. Early decelerations reflect a physiological response to fetal head compression.

Choice B rationale

Fetal head compression during a contraction leads to vagal nerve stimulation, causing a transient decrease in the fetal heart rate. This deceleration is typically gradual in onset and recovery, mirroring the contraction pattern, and is considered a benign finding.

Choice C rationale

Umbilical cord compression typically results in variable decelerations, which are abrupt decreases in FHR that are not necessarily associated with uterine contractions. The shape and timing of variable decelerations differ significantly from the gradual, consistent pattern of early decelerations.

Choice D rationale

Utero-placental insufficiency usually manifests as late decelerations, which are gradual decreases in FHR that begin after the peak of the contraction and recover after the contraction ends. This pattern indicates fetal hypoxia and is a concerning finding, distinct from early decelerations.

Choice A rationale

An increase in baseline variability is generally considered a reassuring sign of fetal well-being, indicating a responsive central nervous system and adequate oxygenation. While important to monitor, it is not a specific periodic pattern to observe immediately following membrane rupture due to potential cord compression. Normal baseline variability ranges from 6 to 25 beats per minute.

Choice B rationale

Non-periodic accelerations are abrupt increases in fetal heart rate above the baseline, typically lasting less than 30 seconds. They are usually a reassuring sign, often occurring with fetal movement or stimulation. While their presence is noted, they are not the primary periodic pattern to observe immediately after membrane rupture for potential complications.

Choice C rationale

Early decelerations are gradual decreases in fetal heart rate that mirror the uterine contractions. They are thought to be caused by fetal head compression and are generally considered benign. While their presence is documented, they are not the most concerning pattern immediately after membrane rupture, which raises the risk of cord issues.

Choice D rationale

Variable decelerations are abrupt decreases in fetal heart rate that are variable in timing and shape in relation to uterine contractions. They are often caused by umbilical cord compression, which is a significant risk factor immediately following the rupture of membranes, as the fluid cushion around the cord is reduced. Prompt identification is crucial for intervention.
