Test 3 Review Flashcards

Q

What carries the oxygenated blood? (ductus venosus or ductus arteriosus)

A

Ductus venosus carries oxygen rich blood from the umbilical vein directly to the IVC which empties directly into the right atrium
p 1126

From the right ventricle, the blood courses from the pulmonary artery into the ductus arteriosus and thru the descending aorta to provide oxygenated blood to the abdominal organs.
p 1126

i think the answer is ductus venosus

Q

What is the difference between asymmetric and symmetric IUGR?

A

Symmetric IUGR is a fetus that is small in all physical parameters, usually the result of a severe insult in first tri
Asymmetric IUGR is more common and is usually caused by placental insufficiency, possibly the result of maternal disease

28
Q

In a macrosomic fetus what might the placenta look like?

A

Placentas of the macrosomic fetus can become significantly large and thick because they are not immune to the growth-enhancing effects of fetal insulin. Greater than 5 cm in thickness.
