AMCB PRACTICE QUESTION REVIEW QUESTIONS AND
DETAILED ANSWERS|ALREADY GRADED A
Latent Phase of Labor Correct Ans- Onset of labor until cervical dilation
reaches 4-6 m
Long arc rotation Correct Ans- Most commonly performed by babies
beginning labor in LOP presentation
FHR Variability: controlling system Correct Ans-
Parasympathetic/sympathetic nervous system
Pudendal Anesthesia Administration Correct Ans- Ideal timing to
administer in multip women is at 8-9cm, just before complete dilation, to
cover birth and repair
Sudden fetal bradycardia in 2nd stage Correct Ans- commonly caused
by a vagal response in the fetus related to descent
Engagement occurs when Correct Ans- Widest diameter of the
presenting part descends to or below the pelvic inlet
The widest diameter of the fetal head is the biparietal diameter
Iron Deficiency Labs Correct Ans- Microcytic, hypochromic
Low Hgb, Hct, MCV, MCHC, RBCs, iron, ferritin
High TIBC
,High RDW
Leg cramp in pregnancy relief Correct Ans- Flexion of the foot
Changes in respiratory system in pregnancy Correct Ans- May cause
increased chest diameter; thoracic circumference increases by 5-6cm and
residual volume decreases
polyhydramnios fetal etiology Correct Ans- CNS or GI tract fetal
anomalies
Autosomal Recessive Trai Correct Ans- Expressed only when both
copies of the gene are the same; ex cystic fibrosis and sickle cell anemia
Infant effects of maternal tobacco use Correct Ans- IUGR, premature
birth, and SGA
Severe features of preeclampsia Correct Ans- thrombocytopenia, renal
insufficiency, impaired liver function, pulmonary edema, and cerebral or
visual symptoms
Hemodynamic Changes in Initial Postpartum Period Correct Ans-
Elevated cardiac output for as long as 48 hours after birth; cardiac output
increases 60-80%
,Placental transport of oxygen and glucose Correct Ans- Transported
across the placenta via facilitated diffusion
Amniotic fluid production Correct Ans- Produced by the amniotic
epithelium; water transfers across the amnion and through the fetal skin
-in the 2nd trimester, the fetus starts to swallow, urinate, and inspire
amniotic fluid
Trichomoniasis treatment in Pregnancy Correct Ans- Metronidazole
(Flagyl) 2 g PO x1 at any stage in pregnancy
Ritgen maneuver Correct Ans- Assist in delivery of the fetal head during
extension
Used to expedite the delivery of the fetal head when necessary
It involves applying upward pressure from the coccygeal region to
extend the head during actual delivery, thereby protecting the
musculature of the perineum.
Maternal breastfeeding contraindications Correct Ans- HIV positive and
untreated
Active TB
Illicit drug use
Take prescribed chemotherapy agents
Acrocyanosis Correct Ans- Bluish discoloration of the hands and feet
caused by reduced peripheral circulation.
, Normal within first 24-48 hours after birth
Variable decelerations description Correct Ans- Abrupt in nature
Decrease in FHR from a baseline of >15BPM lasting >15 seconds but
<2 min
Anterior asynclitism Correct Ans- exists when the sagittal suture is
closer to the sacrum and the anterior parietal bone is presenting first
Oligohydramnios fetal etiology Correct Ans- Associated with
genitourinary abnormalities in the fetus
Midplane Definition/Elements Correct Ans- Ischial spines distance and
sacrum
Distance b/w the ischial spines normally measures 10 cm
Smallest diameter of the pelvis
Chorionic Villi Correct Ans- The chorionic villi develop from the outer
wall of the blastocyst which establishes and intimate connection with the
endometrium and gives rise to the placenta
Blood in the chorionic villi pertains to the circulation of the fetus
Umbilical Cord Vessels Correct Ans- 2 arteries that carry fetal
deoxygenated blood to the placenta, smaller in diameter
