Hydramnios, or polyhydramnios, is defined by an amniotic fluid volume of which threshold?

• A. Greater than 2000 mL
• B. Greater than 1000 mL
• C. Greater than 3000 mL
• D. Greater than 1500 mL

Answer: (A)

Polyhydramnios is diagnosed when there is too much amniotic fluid. The commonly used volume threshold is greater than 2000 mL, which aligns with how ultrasound measurements are interpreted in practice (an amniotic fluid index over about 24 cm or a maximum vertical pocket over 8 cm corresponds to roughly that volume). The other volumes listed do not match the standard diagnostic cutoff, with 3000 mL indicating more severe accumulation but not the typical threshold, and 1000 or 1500 mL being below the threshold.
