Final answer:
Using the maximum vertical depth method, a pocket greater than 7 cm indicates polyhydramnios, while a pocket less than 3 cm indicates oligohydramnios; the 2-8 cm range is generally considered normal.
Step-by-step explanation:
Using the maximum vertical depth method of assessing the Amniotic Fluid Volume (AFV), a pocket that is greater than 7 cm indicates polyhydramnios, while a pocket less than 3 cm indicates oligohydramnios. A measurement between 2 and 8 cm is often considered the normal range, so none of the provided options exactly match the widely accepted standards. Amniotic fluid is crucial for fetal development, providing protection and essential nutrients. It plays a critical role in lung development, and an abnormal volume can lead to severe conditions such as hypoplastic lungs.
