Nur 2633 Module 3 4 5 Lesson Content Exam 2

MODULE 3, 4, 5 LESSON CONTENT:FETAL MONITORING Equipment used - Fetal monitor, paper, belts, Ultrasound for fetal heart tones, and Toco - for uterine contractions. 5 pieces of information on the fetal monitor - baseline, variability, accelerations, decelerations,maternal uterine activity Baseline - where the fetal heart rate is over time. Normal parameter is 110 - 160 Variability - the changes the fetal heart rate makes moment to moment due to the influence of the sympathetic nervous system. (can not read prior to 28 weeks, nervous system is immature) Accelerations - heart rate above the baseline - this is a very positive finding always a good thing,shows the baby is getting good perfusion through a healthy placenta Decelerations - appear for different reasons -heart rate decelerates below the baseline. Early decelerations - from head compression the fetal heart rate 'mirrors' the contraction. Late decelerations - from placental insufficiency. Placenta has or is under risk of poor perfusion. Risk factors - HTN, DM, poor nutrition, smoking, drugs, alcohol Variable decelerations - from cord compression. Interuterine resuscitation - needed to improve the fetal circulation. Nursing interventions are as follows: Change the maternal position, increase fluid intake ( IV bolus), Stop Pitocin if running,
