Q

In a term newborn with neonatal encephalopathy, which MOST STRONGLY suggests that acute hypoxia-ischemia in the peripartum or intrapartum period was a contributor?

A

Presence of multi-system organ failure increases the chances of hypoxic-ischemic injury as an explanation for neonatal encephalopathy.
This finding has the strongest association with hypoxic-ischemic encephalopathy of the options presented.
However, it alone is insufficient for the diagnosis.

Q

Name some sentinel obstetric events?

A

sentinel obstetric events occurring immediately before or during labor and delivery increase the chance of hypoxic-ischemia contributing to neonatal encephalopathy. Examples include uterine rupture, placental abruption, umbilical cord prolapse, amniotic fluid embolus, and hemorrhage associated with vasa previa.

Q

Recommendation for delivery mode in twins with cephalic presentation of Twin A?

A

Perinatal outcomes for twin gestations in which first twin is in cephalic presentation are not improved by cesarean delivery. Thus, women with either cephalic/cephalic-presenting twins or cephalic/noncephalic-presenting twins should be counseled to attempt vaginal delivery

Q

Which of the following is the most common indication for fetal intracardiac intervention?

A

Most common is balloon aortoplasty in fetus.
Possible fetal procedures include aortic valvuloplasty for critical aortic stenosis; atrial septostomy for hypoplastic left heart syndrome with intact interatrial septum, and pulmonary valvuloplasty for pulmonary atresia with intact interventricular septum.

A

With normal UA Doppler deliver at 38-39 weeks
If absent end diastolic flow deliver at 34 weeks, if the antepartum testing is reassuring

Q

A G1P0 is admitted for preterm labor at 26 weeks gestation. Which of the following is the MOST appropriate reason to administer intravenous magnesium sulfate?

A

Reduction in cerebral palsy AND death (not just CP alone)

24
Q

What best describes the research regarding the efficacy of activity restriction in reducing the risk of preterm birth in this patient?

A

Only studied retrospectively and found to be harmful towards preterm birth.

25
Q

What is the incidence of a stillbirth per thousand (corrected for anomalies and unpredictable causes) within 1 week of a normal modified biophysica profile?

A
The following is a list of antenatal surveillance test modalities and their associated incidence of stillbirth per thousand, within one week of testing:
 Non stress test- 1.9 
 Biophysical profile- 0.8 
 Modified biophysical profile- 0.8 
 Contraction stress test- 0.3
26
Q
Which of the following has the best positive predictive value for subsequent development of preeclampsia?
 First trimester Uterine Doppler
 Low PAPP-A
 Second Trimester MSAFP
 Clinical Risk Assessment
A

Clinical Risk Assessment

27
Q

Why do infants born to diabetic mothers have increased bilirubin?

A

Increased polycythemia from glucose stimulation resulting in increased bilirubin productiondue to RBC breakdown.

28
Q

A cesarean delivery is performed at 33 weeks gestation due to preterm labor and breech presentation. After the initial resuscitation, the neonate has persistent tachypnea, grunting, and cyanosis and continuous positive airway pressure (CPAP) is initiated. The chest x-ray shows low lung volumes, a diffuse reticulogranular pattern, and air bronchograms. Which is the most likely diagnosis?

A

Respiratory Distress Syndrome

29
Q

The single most important clinical benefit for delayed cord clamping in preterm infants is the possibility for a nearly 50% reduction in?

A

intraventricular hemorrhage

30
Q

ECMO Inclusion criteria?

A

Birth weight >2 kg
Gestational age >34 weeks
Absence of significant intracranial or other hemorrhage
Absence of lethal congenital or chromosomal abnormalities

31
Q

Mom is CF Carrier, dad tested and is negative for 80% of mutations, population risk is 1/25 of being a carrier, what is the risk of an affected child?

A

1/2 (mom) * 1/25 (carrier risk) *0.20(% left that he wasn’t tested for) * 1/2 (risk to pass it on) = 1/500?

32
Q

cfDNA RHD testing requires what to be valid?

A

SNP > 6 of 92 differing from the Mom (if fetus is female to make sure its not moms)

33
Q

If cdDNA RHD testing is not valid due to low SNP what can you do?

A

Consider repeating if time to get results back would be in time to initiate surveillance.

34
Q

A
Alphabetical ascending order
 #1 Cardiovascular
 #2 Chromosomal
 #3 Hematologic
 #4 Infectious
35
Q

Management of TTTS once diagnosed stage 1?

Prognosis?

A

Most experts agree that expectant management with weekly ultrasound surveillance is the appropriate choice to manage twins with Stage 1 TTTS.
The overall survival rate for Stage 1 TTTS with expectant management is 86%,after amnioreduction is 77% and after laser photocoagulation is 86%.
So expectant management is whats most recommended.

A

not be used in women with severe (decompensated) cirrhosis

its okay in mild cirrhosis or chronic hepatitis b

A

Combined oral estrogen/progestin contraceptives can be safely used in women with a history of restrictive procedure, but should be avoided in women with a history of malabsorptive procedure.
