Relias - Fetal Heart Monitoring | With Complete Questions And Answers | 2023/24

fetal hypoxemia can occur under the following conditions {Ans: - excessive uterine contractions - prolonged contractions without adequate resting tone or duration between contractions - abnormal uterine physiology or anatomy is present - separation of placenta and uterus (recurrent late, variable, or prolonged decels suggest this)}fetal acidosis {Ans: - when O2 is decreased to fetus, tissue hypoxia results in acidosis, which then shows a drop in pH, a loss of bicarb, and increase in base deficit}causes of late decels {Ans: - uterine tachysystole - maternal hypotension - placental abruption - severe maternal anemia}(1) hypoxemia vs. (2) hypoxia {Ans: 1 - reduce O2 in blood 2 - reduced O2 delivery at tissue level}moderate FHR variability {Ans: - amplitude 6 to 25 bpm - represents well oxygenated, nonacidemic}uterine blood supply {Ans: - uterine arteries deliver oxygenated blood to spiral arteries which bring oxygen rich blood to intervillous space of placenta that has fetal capillaries - fetal capillaries carry the O2 rich blood to umbilical VEIN that goes to fetus -in contrast, the umbilical ARTERIES return waste products to that intervillous space that go into mother's venous system}acidosis {Ans: pH below 7.35 pH is low (acidosis
