FetalHeart
Monitoring
Quiz
Prior
to
32
weeks
gestation,
a
fetal
heart
rate
acceleration
is
defined
as
an
increase
in
FHR
that
must
be
at
least
______
above
the
baseline
and
must
last
at
least
________.
-
ANS
10
bpm
above
the
baseline
and
the
acceleration
must
last
at
least
10
seconds
FHR
variability
can
be
interpreted
with
an
external
monitor
-
ANS
using
a
Doppler
technology
called
autocorrelation
As
the
history
of
EFM
continues
to
unfold,
one
thing
is
certain:
research
continues
to
be
needed
to
identify
best
practices
for
EFM
or
IA
in
laboring
women.
Technology
alone
will
never
be
the
answer.
Standardization
of
terminology,
multidisciplinary
education
regarding
FHR
interpretation
and
underlying
physiology,
and
management
based
on
collaboration
and
teamwork
remain
the
best
approach
to
safe
passage
for
mother
and
child,
regardless
of
the
technology
employed.
True/False
-
ANS
true
Fetal
oxygenation
consists
of
two
basic
elements:
the
fetal
response
to
interruption
of
oxygen
&
transfer
of
oxygen
from
the
environment
to
the
fetus
True/False
-
ANS
true
Three
anatomic
shunts
_________,
_________
&
_________
permit
fetal
blood
to
bypass
the
liver
and
the
lungs
-
ANS
ductus
venosus,
ductus
arteriosus
and
foramen
ovale
Vasa
previa
is
a
placental
vessel
that
traverses
the
chorioamniotic
membrane
in
close
proximity
to
the
cervical
os
True/False
-
ANS
true
Name
3
causes
of
interrupted
transfer
of
oxygen
from
the
environment
to
the
fetus
-
ANS
lungs,
heart,
vasculature,
uterus,
placenta,
umbilical
cord
Accumulation
of
lactic
acid
in
the
tissues
results
in
metabolic
acidosis.
lactic
acid
accumulation
can
lead
to
utilization
of
buffer
bases
(primarily
bicarbonate)
to
help
stabilize
tissue
pH.
If
the
buffering
capacity
is
exceeded,
the
blood
pH
may
begin
to
fall,
leading
to
metabolic
acidemia.
Eventually,
recurrent
or
sustained
tissue
hypoxia
and
acidosis
can
lead
to
loss
of
peripheral
vascular
smooth
muscle
contraction,
reduced
peripheral
vascular
resistance,
and
hypotension,
in
turn
leading
to
potential
hypoxic
ischemic
injury
to
many
tissues,
including
the
brain
and
heart.
True/False
-
ANS
true
There
is
a
broad
consensus
in
the
literature
that
the
presence
of
moderate
variability
or
accelerations
of
the
FHR
reliably
exclude
hypoxic
injury
at
the
time
they
are
observed.
