The vessels of the umbilical cord

What are two arteries and one vein?

100
How oxygen passes into the placental villi
What is simple diffusion?
100
Tetanic contraction
What is a contraction called that lasts longer than 120 seconds?
100
Maternal supine position
What maternal positioning is avoided to promote uterine blood flow?
100
Carries oxygenated blood to the fetus
What is the umbilical vein?
200
Gelatinous substance that protects the vessels
What is Wharton's Jelly?
200
Increases by 30% to 50% during pregnancy above the non pregnant state, to facilitate placental perfusion and fetal oxygenation
What happens to maternal cardiac output during pregnancy?
200
Maneuvers to assess fetal lie, presentation, position and descent, by abdominal palpation
What are Leopold's Maneuvers?
200
During augmentation of labor, You stop this when fetal distress is apparent
What is Oxytocin, Pitocin, or prostaglandin?
200
The primary organ for fetal respiration and nutrition
What is the placenta?
300
Normal Fetal heart rate range
What is 110-160?
300
A factor determining maternal oxygen delivery to her tissue and placenta
What is hemoglobin concentration?
300
Fetal heart rate deceleration associated with cord compression
What is variable deceleration?
300
Breathing patterns, massage, guided imagery, reposition, distractions
What are comfort measures or non pharmacological pain relief interventions?
300
> 5 contractions in 10 minutes, averaged over a 30 minute window.
What is tachysystole?
400
Part of the autonomic nervous system that decreases the fetal heart rate: A. Sympathetic B. Parasympathetic C. Chemoreceptor
What is parasympathetic?
400
Hyperthermia, infection, dehydration, hyperthyroidism, anxiety, CNS stimulating drugs
What are Maternal factors leading to fetal tachycardia?
400
Determined in a 10 minute window, excludes accels and decels, shows with irregular fluctuations in amplitude of peaks and troughs
What is baseline variability?
400
Do these things for a prolonged deceleration
What are position change, IV fluid bolus, oxygen, stop Pitocin, tocolytic administration, reduce maternal pain?
400
During interruptions of oxygenation, the fetus relies on this
What is fetal reserve?
500
Fetal circulation ensures delivery of blood to these vital organs
What are the brain, heart, and adrenals?
500
Maternal arteries and spiral arteries remain in a state of A. Vasoconstriction B. Vasodilation C. Spasm
How does Vasodilation maintain uterine blood flow, placental perfusion, and fetal well-being?
500
A gradual decrease in FHR, onset is delayed in timing, nadir occurs after peak of ctx
What is a late deceleration?
500
Administered to relax the uterus for intractable tachysystole (drug, dose, route)
What is Terbutaline 0.25 mg, sq
500
Maternal factors that compromise Blood flow to the placenta
What are smoking, abruptio, post term (aging placenta), diabetes, hypertension, hypotension?
