<quiz display=simple>
 
{Which of the following options would be the earliest invasive diagnostic technique carried out clinically:
|type="()"}
- &nbsp; ultrasound
|| Incorrect! {{Ultrasound}} is not an invasive diagnostic technique, while the {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
- &nbsp; amniocentesis
|| Incorrect! {{Amniocentesis}} is a prenatal diagnostic test carried out mainly between {{GA}} week 14 to 18, the {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
+ &nbsp; chorionic villus sampling
|| Correct! {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12. Amniocentesis is a later test carried out mainly between {{GA}} week 14 to 18.
- &nbsp; none of the above
|| Incorrect! {{chorionic villus sampling}} test is done in {{GA}} week 10 to 12.
 
{Which placental parameter is measured by ultrasound at the mid-portion from the chorionic plate to the basilar plate.
|type="()"}
- &nbsp; placental diameter
|| Incorrect! placental diameter is measured in the transverse section by calculating the maximum dimensions of the chorionic surface.
+ &nbsp; placental thickness
|| Correct! Note that the placental thickness approximates in millimeters to the weeks of gestation.
- &nbsp; placental volume
|| Incorrect! placental volume is measured by a range of different methods and calculations, more recently with three-dimensional ultrasound.
- &nbsp; placenta position
|| Incorrect! placental thickness is measured by ultrasound at the mid-portion from the chorionic plate to the basilar plate.
 
{Doppler ultrasound of the placental cord can be used to mainly measure:
|type="()"}
- &nbsp; placental cord diameter
|| Incorrect! While ultrasound will show the placental cord diameter, {{doppler ultrasound}} is a noninvasive measure of blood flow and blood pressure by bouncing ultrasound off circulating red blood cells.
- &nbsp; placental artery diameter
|| Incorrect! While ultrasound will show the placental artery diameter, {{doppler ultrasound}} is a noninvasive measure of blood flow and blood pressure by bouncing ultrasound off circulating red blood cells.
- &nbsp; placental vein diameter
|| Incorrect! While ultrasound will show the placental vein diameter, {{doppler ultrasound}} is a noninvasive measure of blood flow and blood pressure by bouncing ultrasound off circulating red blood cells.
- &nbsp; placenta position
|| Incorrect! While ultrasound will show the placenta position, {{doppler ultrasound}} is a noninvasive measure of blood flow and blood pressure by bouncing ultrasound off circulating red blood cells.
+ &nbsp; placental blood flow
|| Correct! {{doppler ultrasound}} is a noninvasive measure of blood flow and blood pressure by bouncing ultrasound off circulating red blood cells.
 
{The amniotic fluid volume increases as the embryo and fetus grows, with the rate of change varying during the pregnancy. When typically is the period of maximum weekly volume increase?
|type="()"}
- &nbsp; up to 8 weeks
|| Incorrect! up to 8 weeks - increases at 10 ml/week
- &nbsp; 8 to 13 weeks
|| Incorrect! 8 to 13 weeks - increases at 25 ml/week
+ &nbsp; 13 to 21 weeks
|| Correct! 13 to 21 weeks - increases at 60 ml/week
- &nbsp; 21 to 33 weeks
|| Incorrect! amniotic volume increase starts decreasing and eventually levels.
- &nbsp; 34 weeks
|| Incorrect! amniotic volume peaks at about 800 mL, but not maximum production.
- &nbsp; 40 weeks
|| Incorrect! amniotic volume increase starts decreasing and eventually levels and at 40 weeks (GA) has about 600 mL at term.
 
 
{Cord stem cells can be derived from which of the following tissues:
|type="[]"}
+ &nbsp; placental cord blood
|| Correct!
+ &nbsp; placental cord connective tissue
|| Correct!
- &nbsp; maternal placental tissue
|| Incorrect!
- &nbsp; all of the above
|| Incorrect!
- &nbsp; none of the above
|| Incorrect!


<quiz display=simple>


{Which of the following is the most correct statement about the primitive streak:
{Which of the following diagnostic techniques has in the past identified as having the higher risk for miscarriage?
|type="()"}
|type="()"}
- &nbsp; extends from the primitive node to the parachordal plate
- &nbsp; ultrasound
- &nbsp; is a primary inducer during organogenesis
|| Incorrect! {{Ultrasound}} is non-invasive and has not been shown to affect miscarriage rates.
+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
- &nbsp; amniocentesis
|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
|| Incorrect! {{Amniocentesis}} when the test is carried out by an obstetrician experienced in the technique, the risk of a miscarriage related to the test is said to be about 1%.
- &nbsp; persists as the parachordal plate
+ &nbsp; chorionic villus sampling
- &nbsp; all of the above are correct
|| Correct! {{chorionic villus sampling}} when the test is carried out by an obstetrician experienced in the technique, the risk of miscarriage related to the test is said to be about 2%. Though at least one recent study has shown about an equal risk to {{Amniocentesis}}. {{#pmid:27416616}}
- &nbsp; fetal cells from maternal blood
|| Incorrect! [[Fetal Cells in Maternal Blood]] is a [[Non-Invasive Prenatal Testing|noninvasive prenatal test]] (NIPT) and has not been shown to affect miscarriage rates.
