Concerning small-for-gestational-age (SGA) infants and intrauterine growth restriction (IUGR), nurses should be aware that:
1. in the first trimester, diseases or abnormalities result in asymmetric IUGR.
2. infants with asymmetric IUGR have the potential for normal growth and devel-opment.
3. in asymmetric IUGR, the weight will be slightly more than SGA and length and head circumference will be somewhat less than SGA.
4. symmetric IUGR occurs in the later stages of pregnancy.
2
1, 3, 4. Incorrect. IUGR is either symmetric or asymmetric. Symmetric occurs in the first trimes-ter; SGA infants have reduced brain capacity. Asymmetric occurs in the later stages of pregnancy. Weight is less than the 10th percentile; head circumference is greater than the 10th percentile. Infants with asymmetric IUGR have the potential for normal growth and development.
2. Correct. IUGR is either symmetric or asymmetric. Symmetric occurs in the first trimester; SGA infants have reduced brain capacity. Asymmetric occurs in the later stages of pregnancy. Weight is less than the 10th percentile; head circumference is greater than the 10th percentile. Infants with asymmetric IUGR have the potential for normal growth and development.
