Q

New Terminology Matching

Example: G2 P0101
Gravida (pregnancies) and then the numbers after the Para you have TPAL

A

A → 2 Term >37wks

B → 1 Preterm <37wks

C → 3 Abortions (Miscarriage or other loss)

D → 4 Living Children

Therefore a G2 P0101 = G2 pregnancies, P = 0 term births, 1 preterm, 0 abortions and 1 living child
