Which pattern in the fetal heart rate would increase
suspicion of a nuchal cord? - ....ANSWER...C. Variable
decelerations
Shelby delivers a male infant with Apgar scores of 2
and 3. Umbilical arterial cord blood gases show:
pH: 6.92
pCO2: 79
pO2: 11
BE: -7.6
What is the correct interpretation of the cod blood
gas? - ....ANSWER...A. Respiratory academia
,If fetal arterial pressure begins to fall below normal
levels: - ....ANSWER...A. BARORECEPTORS CAUSE
VASOCONSTRICTION AND INCREASE THE FHR
An increase in arterial blood pressure produces
vessel distension and causes arterial baroreceptors
to send neuronal messages to the cardioinhibitory
center, which in turn causes rapid slowing of the
fetal heart rate via the parasympathetic vagus nerve.
A decrease in arterial pressure results in an
increased heart rate.
Which of the following is an extrinsic influence on
the FHR? - ....ANSWER...Fetal-placental circulation
Fetal heart rate vaiability is definded as fluctuations
in the baseline that are irregular in -
....ANSWER...AMPLITUDE and FREQUENCY
The most highly oxygenated blood in fetal circulation
is carried by: - ....ANSWER...Ductus venosus
An increase in the fetal heart rate immediately
preceding a variable deceleration is caused by: -
....ANSWER...Occlusion of the umbilical vein
, The etiology of variable decelerations is likely
related to umbilical venous and arterial occlusion.
Initially, with occlusion of the thin-walled umbilical
vein, venous return to the fetal right atrium is
reduced, producing a reflex tachycardia. This pattern
often is observed as a shoulder on the FHR monitor
strip immediately before the abrupt variable FHR
deceleration

When assessing a FHR tracing, the first step is to -
....ANSWER...Estabilish the baseline rate
Which deceleration in the FHR is considered benign
and does not require an intervention to correct? -
....ANSWER...Early deceleration
If the umbilical vein is the only vessel occluded
during cord compression -
....ANSWER...Deoxygenated blood cannot be removed
from fetal circulation
