Which term describes increased amniotic fluid volume?

Which term describes increased amniotic fluid volume?

• A. Poly
• B. Oligo
• C. Hydrocephalus
• D. Banana Sign

Answer: (A)

Increased amniotic fluid volume is described by polyhydramnios, often shortened to poly. The prefix poly- means many or much, and hydramnios refers to fluid in the amniotic sac, so this term directly describes excess fluid. This is different from oligohydramnios, where olig/o means few and indicates too little fluid. The other two options aren’t about fluid volume: hydrocephalus is an accumulation of fluid within the brain’s ventricles, and the Banana Sign is a sonographic appearance of the cerebellum seen with certain fetal brain conditions, not a term for fluid amount.
