Refer to tracing A-3. Silvia's vital signs were BP 123/70,
pulse 86 bpm, respirations 18/minute. The oxytocin was
infusing at 11 mU/min and VE findings were 3-4 cm, 80%
effaced, -2 station, membranes intact and cephalic
presentation, with a moderate amount of blood on vaginal
exam. WHICH OF THE FOLLOWING IS AN
APPROPRIATE PHYSIOLOGIC GOAL BASED ON
TRACING A-3? - Answer-Maximize utero-placental
circulation
Refer to tracing A-3. The correct assessment of this
tracing includes: - Answer-Sinusoidal pattern
Refer to tracing A-4. At the time of tracing 4, the resident
performed an AROM and fluid was clear. A vaginal exam
indicated the cervix was unchanged. The resident placed a
fetal spiral electrode and had difficulty placing an IUPC.
The nurse could palpate contractions but could not
determine the frequency and duration by palpation. The
oxytocin was discontinued, an intravenous fluid bolus was

administered, and Silvia was repositioned. WHAT FHR
CHARACTERISTICS SHOULD THE NURSE REPORT TO
THE PROVIDER? - Answer-Recurrent decelerations
Refer to tracing A-4. The correct physiologic interpretation
of this tracing is: - Answer-Fetal hypoxemia may be
present
Refer to tracing A-5. At 1332, the resident successfully
placed the IUPC and an amnioinfusion was initiated at
1430. The resident telephoned the provider to report the
initiation of the amnioinfusion. WHICH INTRINSIC
HOMEOSTATIC RESPONSE IS THE FETUS
DEMONSTRATING? - Answer-Baroreceptor
Refer to tracing A-5. An amnioinfusion is intended to
relieve which extrinsic factor that compromises oxygen
transport? - Answer-Umbilical cord compression
At 1410, the nurse again telephoned the provider to report
Silvia's status, including two more dark red blood clots and
absent variability with recurrent decelerations, and asked
the provider to come to the bedside for evaluation. The
provider indicated she was "on the way to the hospital"

and ordered an emergency cesarean to be started by the
senior resident. Silvia was prepped for cesarean birth. The
nurse is planning to document her telephone report to the
attending physician. Given the emergent situation, the
best approach to documentation would be: - Answer-
Continue providing care for Silvia and write a late entry
summarizing the conversation after the cesarean is
completed
What additional action should the nurse take to minimize
risk, based on this case scenario? - Answer-Ensure that
the neonatal team is notified of the circumstances and is
present for the birth
The provider delivered a male infant by cesarean birth at
1447 and noted bloody amniotic fluid at delivery. Apgar
scores were 3/3/3 at 1/5/10 minutes. The infant was visibly
pale. Inspection of the placenta revealed a velamentous
insertion of the umbilical cord and a ruptured fetal vessel.
The umbilical cord gases were: pH 6.88/PCO2 114
mmHg/PO2 10 mmHg/bicarb 15/base excess -20 mEq/L.
The initial hematocrit was 20% and the hemoglobin was 8.
WHICH INTERPRETATION OF THSE UMBILICAL CORD
AND INITIAL NEONATAL BLOOD RESULTS IS
CORRECT? - Answer-The neonate is anemic

THESE UMBILICAL CORD GASES INDICATE: - Answer-
Mixed acidosis (respiratory & metabolic)
CASE STUDY B) NELL. Nell, a 24-year-old G3 P020 at
42&3 weeks arrived on L&D for an evening IOL for post-
dates. Nell has had an exploratory lap. to remove scar
tissue on her L ovary and intestines and has had
infrequent menstrual cycles. She had has 2 SABs - at 12
and 5 weeks. Prenatal labs were WDL. Her thyroid is
enlarged; however, her TSH, T4, and T3 were done at 39
weeks and were WDL. Nell has a family history of HTN.
An US at 19 weeks revealed a low-lying placenta that
resolved by 37 5/7 weeks. Today in triage, an US revealed
an EFW of 3300g and an AFI of 3 cm. Nell has had
reactive NSTs. Admission vital signs were WDL. SVE
findings: fingertip, 40%, and -2 station. Membranes intact
and cephalic presentation. Nell denied feeling regular
