Relias - Fetal Heart Monitoring 2025/2026
Exam Questions and Correct Answers |
New Update
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 blood
2 - reduced O2 delivery at tissue level
, Fetal anaerobic metabolism - 🧠 ANSWER ✔✔- occurs when long term O2
delivery is insufficient to meet cellular needs of tissues
- results in production of lactic acid and other noncarbonic acids
- ACIDOSIS is the presence of excessive acids in tissues
acidosis - 🧠 ANSWER ✔✔pH below 7.35
pH is low
(acidosis is the process that leads to low blood pH, or acidemia)
alkalosis - 🧠 ANSWER ✔✔pH above 7.45
pH is high
buffers - 🧠 ANSWER ✔✔- help maintain acid base homeostasis
