AMCB Practice Question Review with answers
2024\2025 A+ Grade
Latent Phase of Labor
- correct answer Onset of labor until cervical dilation reaches 4-6 m
Long arc rotation
- correct answer Most commonly performed by babies beginning labor in LOP presentation
FHR Variability: controlling system
- correct answer Parasympathetic/sympathetic nervous system
Pudendal Anesthesia Administration
- correct answer 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 answer commonly caused by a vagal response in the fetus related to descent
Engagement occurs when
- correct answer 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 answer Microcytic, hypochromic
Low Hgb, Hct, MCV, MCHC, RBCs, iron, ferritin
High TIBC
High RDW
,Leg cramp in pregnancy relief
- correct answer Flexion of the foot
Changes in respiratory system in pregnancy
- correct answer May cause increased chest diameter; thoracic circumference increases by 5-6cm and
residual volume decreases
polyhydramnios fetal etiology
- correct answer CNS or GI tract fetal anomalies
Autosomal Recessive Trai
- correct answer 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 answer IUGR, premature birth, and SGA
Severe features of preeclampsia
- correct answer thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, and
cerebral or visual symptoms
Hemodynamic Changes in Initial Postpartum Period
- correct answer Elevated cardiac output for as long as 48 hours after birth; cardiac output increases 60-
80%
Placental transport of oxygen and glucose
- correct answer Transported across the placenta via facilitated diffusion
Amniotic fluid production
- correct answer 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 answer Metronidazole (Flagyl) 2 g PO x1 at any stage in pregnancy
Ritgen maneuver
- correct answer 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 answer HIV positive and untreated
Active TB
Illicit drug use
Take prescribed chemotherapy agents
Acrocyanosis
- correct answer Bluish discoloration of the hands and feet caused by reduced peripheral circulation.
Normal within first 24-48 hours after birth
Variable decelerations description
- correct answer Abrupt in nature
Decrease in FHR from a baseline of >15BPM lasting >15 seconds but <2 min
Anterior asynclitism
- correct answer exists when the sagittal suture is closer to the sacrum and the anterior parietal bone is
presenting first
Oligohydramnios fetal etiology
- correct answer Associated with genitourinary abnormalities in the fetus
Midplane Definition/Elements
- correct answer Ischial spines distance and sacrum
, Distance b/w the ischial spines normally measures 10 cm
Smallest diameter of the pelvis
Chorionic Villi
- correct answer 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 answer 2 arteries that carry fetal deoxygenated blood to the placenta, smaller in diameter
1 vein that carries oxygenated blood from the placenta to the fetus; characterized by twisting or
spiralizing
Implantation
- correct answer Occurs 6-7 days after fertilization
Usually in the upper posterior wall of the uterus
Human zygote
- correct answer consists of haploid number of chromosomes; 23 pairs
Possesses half the diploid or number of pairs of chromosomes, 46 pairs, found in somatic, or body cells
Trophoblast
- correct answer The outer layer of cells that develops in the germinal period. These cells provide
nutrition and support for the embryo.
Ultimately becomes the placenta
Drop in diastolic BP during normal pregnancy
- correct answer Lower in the first 2 trimesters because of the development of new vascular beds and
the relaxation of peripheral tone by progesterone, which result in decreased flow resistance
Nullipara
- correct answer women who has not carried a baby to 500g or 20 weeks
