FETAL HEALTH SURVEILLANCE QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+||BRAND NEW!!
What were the 3 main findings of the Cochrane review on intrapartum
EFM vs IA? Ans✓✓✓1. EFM associated with higher C/S
2. No difference in neo or mat mortality or morbidity
3. EFM reduction 50% of neonatal seizures, but no long term differences
(cerebral palsy, mortality or well-being)
The following are outcomes related to which type of labour support?:
Increased spontaneous vaginal birth
Shorter duration of labour
Decreased operative births (cesarean and instrumental vaginal birth)
Decreased use of any analgesia and/or regional analgesia
Fewer low 5-minute Apgar scores
Fewer negative feelings about childbirth experience
Ans✓✓✓Continuous labour support (1-to-1)
When a normal tracing is identified it may be appropriate to interrupt the
EFM tracing for up to _____________ minutes to facilitate periods of
ambulation, bathing, or position change, providing that a) the maternal
fetal condition is stable and b) if Oxytocin is being administered, the
infusion rate is not increased. (III-B) Ans✓✓✓30 minutes
,Is EFM or IA recommended for the labour admission assessment of a
low risk individual? Ans✓✓✓IA
Sympathetic Nervous System Ans✓✓✓1. nerves - medulla oblongata --
> ventricles
2. neurotransmitter is norepinephrine
3. stimulation = increase FHR
Parasympathetic Nervous System Ans✓✓✓1. vagus nerve from medulla
oblongata innervates the sino-atrial (SA) and atrioventricular (AV)
nodes in the heart
2. neurotransmitter is acetylcholine
3. stimulation = decrease FHR
Where are baroreceptors located? Ans✓✓✓1. Aortic arch
2. Carotid sinus
Are barometric responses abrupt or gradual? Ans✓✓✓abrupt (<30
seconds from onset to nadir)
Are chemoreceptor changes abrupt or gradual? Ans✓✓✓gradual (>30
seconds from onset to nadir
, Where are the peripheral and central chemoreceptors located?
Ans✓✓✓peripherally in the aortic arch and carotid sinus
centrally in medulla
Peripheral chemoreceptors produce (slowing/increase) of the FHR,
while central chemoreceptors produce (slowing/increase) of FHR
Ans✓✓✓slowing, increase
Which of the following fetal heart rate regulatory factors gradually
matures and can be expected to be functional at 28 to 32 weeks
gestation?
A) Parasympathetic nervous system
B) Chemoreceptors
C) Baroreceptors
D) Sympathetic nervous system Ans✓✓✓A) Parasympathetic nervous
system
Supine positioning in labour:
A) Increases maternal arterial blood pressure
B) Results in increased uterine activity and dysfunctional labour
C) Causes vena-cava compression and poor placental perfusion
