FH: Assessing fetal well-being(Complete solutions)
Fetal Oxygenation correct answers - Adequate fetal oxygenation requires five related factors.
> Normal flow of oxygenated maternal blood into the placenta
> Normal gas exchange within the placenta
> Patent umbilical cord vessels (need to be functioning, blood going in and out the fetus)
> Normal fetal circulation (Ch.12)KNOW!
> Oxygen carrying function (need enough oxygen, and blood volume to perfuse placenta)
> Sufficient maternal blood pressure to support circulation (too low BP, then it impacts
perfusion)
Single layer fusion is the primary one
Purposes of Fetal Assessment correct answers - Respond to identified maternal risk factors that
place fetus at risk
- Evaluate the fetal status during pregnancy.
- Identify possible hypoxic insult.
Maternal risk factors her age under 17 greater 34 to 35. peri- birth >5, hypertensive, previous C-
section, baby large, mom weight, environmental factors, socioeconomic. How is the fetus doing.
How we see the fetus. (potential fetal follow-up)
Assess possible hypoxic result, poor perfusion to fetus that may cause. (brain, heart)
Fetal Heart Rate Regulation correct answers - Mechanisms that regulate the fetal heart rate
include
> Autonomic nervous system
> Baroreceptors
> Chemoreceptors
> Adrenal glands
> Central nervous system
ANS and CNS evaluation reflects oxygenation to the brain. If the brain sensitive to decrease
oxygenation. Brain looks okay then general fetus perfusion is okay.
KNOW the BOXES: (26-2-26-3)
Contraction stops blood flow
Previa: placenta over the cervix
Infarcts:
Prenatal heart disease in fetus.
, Pathologic Influences
on Fetal Oxygenation correct answers - Maternal cardiopulmonary alterations (good assessment
on mom, DM/HTN/c-section, tells us that shes at higher risk for problems during pregnancy)
- Uterine activity
- Placental disruptions
- Interruptions in umbilical flow
- Fetal alterations
Oligohydramnios and hydro
Intrapartum when mom during labor. Hypertensive during labor and hypotensive after receiving
epidural.
Potential Maternal, Fetal, or Neonatal Risk Factors correct answers - Antepartum period
> Maternal history
> Problems identified during pregnancy
- Intrapartum period
> Maternal problems
> Fetal problems
> Placental problems
Diagnostic assessment of Fetal Well-being correct answers - Blood or Biochemical Assays
> MSAFP (maternal serum) (NTDs)
> Multiple Marker Screens (1st trimester- 11-14 weeks/ helps detects down syndrome)
> Indirect Coombs (screen RH Incompatibility/ mom antibodies to RH positive means RH -)
(pg.647)
> Quads screen (2nd trimester screen/ more sensitive, so find what multiple marker can't find, so
better work of detective neural tube defects)
- Fetal Movements Counts
- Ultrasound
> US Fetal Nuchal Translucency
> BPP
> US guided Amniocentesis
- Chronic Villus Sampling
- Percutaneous Umbilical Blood Sampling
- Assessing with Electronic Fetal Monitoring
> NST
> CST
