- 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. | |||

|type="()"} | |||
- up to 8 weeks | |||
|| Incorrect! up to 8 weeks - increases at 10 ml/week | |||
- 8 to 13 weeks | |||

- 21 to 33 weeks | |||
|| Incorrect! amniotic volume increase starts decreasing and eventually levels. | |||
- 34 weeks | |||
|| Incorrect! amniotic volume peaks at about 800 mL, but not maximum production. | |||
- 40 weeks | |||
|| Incorrect! amniotic volume increase starts decreasing and eventually levels and at 40 weeks (GA) has about 600 mL at term. | |||

|| Incorrect! | |||
{Which of the following diagnostic techniques has in the past identified as having the higher risk for miscarriage? | |||
|type="()"} | |||
- ultrasound | |||
|| Incorrect! {{Ultrasound}} is non-invasive and has not been shown to affect miscarriage rates. | |||
- amniocentesis | |||
|| 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%. | |||
+ chorionic villus sampling | |||
|| 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}} | |||

|| 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. | |||
