Relias - Fetal Heart Monitoring Exam With 100% Correct Solutions 2025/2026 uterine blood supply - answer-- 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 Potential issues that negatively affect fetal oxygenation - answer-*Maternal Oxygenation:* asthma, hyper- or hypo- ventilation *Maternal Circulation:* decreased maternal cardiac output, hypotension, decreased Hgb *Placental O2 and CO2 Exchange:* postterm, abruption, HTN, hypotension, uterine tachysystole *Fetal circulation:* cord compression or occlusion Fetal hypoxemia - answer-- can occur d/t reduced fetal O2 reserves, excessive uterine activity, or reduced uteroplacental blood flow - worsening fetal hypoxemia can lead to abnormal FHR patterns, mostly minimal or absent variability from acidemia (1) hypoxemia vs. (2) hypoxia - answer-1 - reduce O2 in blood2 - reduced O2 delivery at tissue level
