All of the following factors are used to assess intrauterine growth retardation, EXCEPT: 
Select and explain. 
A. Fetal movements, B. Head size, C. Fundal height, D. Abdominal circumference
A: Fetal movements
Answer: A: Fetal movements 
Explanation: Serial fundal height measurements are reasonably accurate screening method to detect intrauterine growth retardation (IUGR). With sonography, the most common method for establishing the diagnosis of fetal-growth restriction is the estimation of fetal weight using multiple fetal biometric measurements like head, abdomen, and femur dimensions. Fetal movements are not indicative of IUGR. Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y. (2010). Chapter 38. Fetal Growth Disorders. In F.G. Cunningham, K.J.
