Which term describes reduced amniotic fluid volume?

• A. Oligo
• B. Poly
• C. Hydrocephalus
• D. Frontal Bossing

Answer: (A)

Reduced amniotic fluid volume is described with the prefix oligo-, forming oligohydramnios. The prefix oligo- means scant or few, so this term specifically signals decreased amniotic fluid. In practice, oligohydramnios is used when amniotic fluid volume falls below normal thresholds (for example, an AFI ≤ 5 cm or a deepest pocket ≤ 2 cm). The other terms aren’t about amniotic fluid quantity: poly- indicates increased fluid, while hydrocephalus and frontal bossing describe other conditions (brain ventricle enlargement and facial/skull features, respectively).
