termed placenta:

• previa
• increta
• accreta
• percreta
• abruptio
• accreta

Chorionic villi of placenta is in direct contact with myometrium Placement of the placental margin within 2 cm of the internal cervical os is termed?

• low lying placenta
• circumvallate placenta
• succenturiate placenta
• marginal placental previa
• incomplete placenta previa
• low lying placenta

marginal placental previa=placental abuts the cervical os

The location of an UV varix is most frequently within the:

• placenta
• fetal liver
• fetal pelvis
• fetal abd
• UC
• fetal abd

focal dilation of UV

The UC is covered by which of the following:

• amnion
• chorion
• vernix
• meconium
• Wharton jelly
• amnion

Insertion of the UC into the end margin of the placenta is

termed:

• a battledore placenta
• placental migration
• a velamentous placenta
• a membranous placenta
• a circumvallate placenta
• battledore placenta

Placenta accreta can be ruled out by observing a normal:

• cord insertion
• chorionic plate
• retroplacental complex
• maternal bladder
• homogenous echo pattern
• retroplacental complex

disrupts the uteroplacental vessels

A single UA is associated with a diameter greater than:

• 2 mm
• 4 mm
• 8 mm
• 10 mm
• 15 mm
• 4 mm

similar in size to UV During the first trimester, the length of the normal UC is

equal to the:

• gestational weeks

B. MSD

C. CRL

D. BPD

• width of the gestational sac

C. CRL

Classical symptoms of placental abruption include:

• painless vaginal bleeding
• sever pelvic pain & vaginal bleeding
• mild abd pain & vaginal spotting
• sever pelvic pain without vaginal bleeding
• mild to sever lower back pain and tender cervix
• sever pelvic pain & vaginal bleeding

painless vaginal bleeding = placenta previa Identification of arterial flow on each side of the fetal bladder verifies which of the following?

• normal renal function
• two umbilical arteries
• normal femoral arteries
• normal aortic bifurcation
• duplicated hypogastric arteries
• two umbilical arteries

UA arise from the hypogastric arteries Extension of an anterior placenta into the maternal

bladder is a sonographic finding associated with:

• adenomyosis
• endometriosis
• placenta increta
• placenta previa
• placenta percreta
• placenta percreta

goes through the myometrial & serosal layer

Which portion of the gestational sac develops into the fetal side of the placenta?

• chorion leave
• choionic villi
• chorion basalis
• chorion parietalis
• chorion frondosum
• chorion frondosum

Which of the following describes a condition where the chorionic plate of the placenta is smaller than the basal plate?

• vasa previa
• abruptio placentae
• battledore placenta
• succenturiate placenta
• circumvallate placenta
• circumvallate placenta

results in attachment of placental membranes to fetal surface of placent

A true nuchal cord is defined as:

• one complete loop of the UC near the fetal neck
• one complete loop of the UC around the fetal neck
• two or more complete loops of the UC near the fetal

neck

• two or more complete loops of the UC around the

fetal neck

• thickening of the nuchal fold coexisting with one

complete loop of the UC around the fetal neck

• two or more complete loops of the UC around the fetal neck

A placenta located immediately adjacent to the cervix is

termed:

• low-lying placenta
• batteldore placenta
• succenturiate placenta
• marginal placental previa
• incomplete placenta previa
• marginal placental previa

Membranous insertion of the UC is termed a:

• vasa previa
• allantois cord
• Wharton cord
• velamentous cord
• battledore placenta
• velamentous cord

Inserts into the amniochorionic membrane of the gestational sac adjacent to the placenta

Fusion of the amnion and chorion should occur by:

• 10 weeks
• 12 weeks
• 16 weeks
• 20 weekd
• 24 weeks
• 16 weeks

An eccentric insertion of the UC into the placenta is

termed a:

• vasa previa
• placenta percreta
• velamentous cord
• battledore placenta
• circumvallate placenta
• battledore placenta

insert of UC into end margin of placenta circumvallate placenta = abnormal placental shape Placental implantation enroaching (abuts) upon the

internal cervical os is termed:

• placental increta
• marginal previa
• placental accreta
• complete previa
• low-lying placenta
• marginal previa

The vascular projections arising from the chorion are

termed:

• allantoic ducts
• chorionic villi
• chorionic leave
• chorionic venules
• myxomatous tissue
• chorionic villi

major functioning unit of the placenta WHich of the following conditions demonstrates extension of the chorionic villi into the wall of the maternal bladder?

• placenta increta
• placentomalacia
• placenta accreta
• placenta percreta
• battledore placenta
• placenta percreta

placenta increta = extension into myometrium

Coiling of the UC is associated with:

• a long cord
• a short cord
• a normal fetus
• premature labor
• chormosomal abnormalities
• a normal fetus

non-coiling is associated with abnormalities Which of the following is the most common placental location for deposits of fibrin to collect?

• basal plate
• subchorionic
• within a placental lake
• within a placental neoplasm
• within the retroplacental complex
• subchorionic

found throughout the placenta but most commonly behind the chorionic plate (subchorionic)
