PU Placenta and Amniotic Fluid Evaluation 2

Question 1

Which condition is most commonly associated with polyhydramnios?

Accepted Answer

Fetal gastrointestinal obstruction

Answer

Upper GI tract obstructions such as esophageal or duodenal atresia prevent the fetus from swallowing amniotic fluid, leading to polyhydramnios.

Question 2

What is a succenturiate lobe of the placenta?

Accepted Answer

An accessory placental lobe separate from the main placenta

Answer

A succenturiate lobe is an accessory lobe of placental tissue connected to the main placenta by blood vessels running through the membranes.

Question 3

What ultrasound finding suggests renal agenesis as a cause of oligohydramnios?

Accepted Answer

Absent or severely abnormal kidneys with no bladder filling

Answer

In renal agenesis, the fetal kidneys are absent and the bladder does not fill, leading to severe oligohydramnios due to absent urine production.

Question 4

Where is the placenta most commonly located in uncomplicated pregnancies?

Accepted Answer

Posterior uterine wall

Answer

The placenta most commonly implants on the posterior uterine wall, though anterior and fundal implantation are also normal locations.

Question 5

What does placental grading assess on ultrasound?

Accepted Answer

Placental maturity based on echogenicity and calcifications

Answer

Placental grading (Grannum classification) assesses maturity by evaluating echogenicity patterns, calcifications, and basal layer changes on ultrasound.
