Late decelerations are a non-reassuring fetal heart rate (FHR) pattern defined as a visually apparent gradual decrease in FHR (onset-to-nadir ≥30 seconds) with return to baseline, where the nadir occurs after the peak of the uterine contraction. The timing is the defining feature — the FHR returns to baseline after the contraction ends. Late decelerations signal uteroplacental insufficiency (UPI) — reduced oxygen delivery to the fetus during peak placental perfusion demand. They represent fetal hypoxia and, if uncorrected, progress to acidosis and neurological injury. Late decelerations are NEVER normal. A single late deceleration may represent transient hypoxia; recurrent late decelerations (occurring with ≥50% of contractions in any 20-minute window) require immediate intervention and physician/midwife notification. Top 3 nursing priorities: 1. Reposition the patient to the left lateral decubitus position to relieve aortocaval compression and improve uteroplacental perfusion 2. Administer 100% O2 via non-rebreather mask at 10–12 L/min and establish IV access for fluid bolus 3. Notify the physician/midwife immediately and prepare for possible emergency delivery (Category III tracing requires urgent action) Common NCLEX trap: Candidates choose to increase oxytocin or...
