(chapter 50 & 51) || All Accurately solved.
Abdominal circumference correct answers Measurement at the level of the stomach, left portal
vein, and left umbilical sign.
Age range analysis correct answers Size and proportionality of the fetal parameter expressed as
age.
Average age correct answers Average age of multiple fetal parameter's age.
Binocular distance correct answers Measurement that includes both fetal orbits at the same time
to predict gestational age.
Biparietal Diameter (BPD) correct answers Fetal transverse cranial diameter at the level of the
thalamus and cavum septum pellucidum.
Crown-Rump length (CRL) correct answers Most accurate measurement for determining
gestational age
Made in the first trimester.

Femoral length correct answers Measurement of the femoral diaphysis
Gestational Sac Diameter correct answers Used in first trimester to estimate appropriate
gestational age with menstrual dates.

humerus.
