Final answer:
A woman at 36 weeks gestation with a fundal height measurement of 34 cm and an abdomen appearing widest from side to side may have a breech fetal presentation.
Step-by-step explanation:
The perinatal nurse suspects that a woman at 36 weeks gestation with a fundal height measurement of 34 cm and an abdomen appearing widest from side to side may have a breech fetal presentation. Breech presentation occurs when the baby's buttocks or feet are positioned to come out first during birth instead of the head. This type of presentation can increase the risk of birth complications, so it's important for healthcare providers to identify it early.
