Exam Questions and CORRECT Answers
The BPP
biophysical profile
measures 5 things: - CORRECT ANSWER - 1. Reactive HR
2. Breathing
3. Body movements
4. Fetal tone
5. Amniotic fluid volume
Physiologic cause of late decelerations - CORRECT ANSWER - Transient interruption in
fetal oxygenation during uterine contractions
fetal fibronectin - CORRECT ANSWER - Biochemical marker used to predict pre-term
birth
Intrauterine Pressure Catheter (IUPC) - CORRECT ANSWER - A catheter that can be
placed through the cervix into the uterus to measure uterine pressure during labor. Some types of
catheters may be inserted for the purpose of infusing warmed saline to add additional intrauterine
fluid when oligohydramnios is present. Useful in the treatment of variable decelerations
variability - CORRECT ANSWER - most important FHR characteristic. It is the most
important indicator of normal fetal pH or acidosis. Moderate ___________ reliably predicts the
absence of fetal metabolic acidosis.
Accelerations in FHR - CORRECT ANSWER - Reflect a sympathetic nervous system
response and results in an increase in FHR
Neural tube defects - CORRECT ANSWER - Elevated maternal serum alpha-fetoprotein is
associated with
, Foramen ovale - CORRECT ANSWER - Shunt that is responsible for the movement
between RT and LT atria. In fetal life it shunts RT to LT
umbilical vein - CORRECT ANSWER - delivers oxygenated blood from the placenta to
the fetus
Catacholamines - CORRECT ANSWER - dopamine, norepinephrine, epinephrine
catecholamines - CORRECT ANSWER - Endogenous, when released during birth process
they are responsible for glucose homeostasis, thermoregulation, increasing BP, and stimulating
surfactant production
surfactant - CORRECT ANSWER - decreases surface tension to maintain a functional
residual capacity
diaphragmatic hernia - CORRECT ANSWER - presents as scaphoid abdomen, heart/breath
sounds greater on the RT side
diaphragmatic hernia - CORRECT ANSWER - abnormal opening in the diaphragm that
allows part of the abdominal organs to migrate into the chest cavity
Cephalohematoma - CORRECT ANSWER - Swelling caused by bleeding between the
osteum and periosteum of the skull. This swelling does not cross suture lines.
choanal atresia - CORRECT ANSWER - cyanotic when quiet, but pinks up when crying is
a sign of
Esophagus - CORRECT ANSWER - ETT tube is where if breath sounds can be heard in
the lung fields and over the stomach
