Fetal Health Surveillance | Set 1 Questions and Answers with
100% Correct Answers | Latest Version
Question 1.
What were the 3 main findings of the Cochrane review on intrapartum EFM vs IA?
Correct Answer: 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)
Question 2.
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
Correct Answer: Continuous labour support (1-to-1)
Question 3.
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 adminis-
tered, the infusion rate is not increased. (III-B)
Correct Answer: 30 minutes
Question 4.
Is EFM or IA recommended for the labour admission assessment of a low risk individual?
Correct Answer: IA
Question 5.
1. nerves - medulla oblon- gata --> ventricles
2. neurotransmitter is norepinephrine
3. stimulation = increase FHR
Correct Answer: Sympathetic Nervous System
Question 6.
Parasympathetic Nervous System
Correct Answer: 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
, Question 7.
Where are baroreceptors located?
Correct Answer: 1. Aortic arch
2. Carotid sinus
Question 8.
Are barometric responses abrupt or gradual?
Correct Answer: abrupt (<30 seconds from onset to nadir)
Question 9.
Are chemoreceptor changes abrupt or gradual?
Correct Answer: gradual (>30 seconds from onset to nadir
Question 10.
Where are the peripheral and central chemoreceptors located?
Correct Answer: peripherally in the aortic arch and carotid sinus centrally in
medulla
Question 11.
Peripheral chemoreceptors produce (slowing/in- crease) of the FHR, while central
chemoreceptors produce (slowing/increase) of FHR
Correct Answer: slowing, increase
Question 12.
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
Correct Answer: A) Parasympathetic nervous system
Question 13.
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
D) Causes catecholamine release and increased maternal heart rate
Correct Answer: C) Causes vena-cava compression and poor placental perfusion
