Legal Implication • Nurses must exercise caution when discussing obstetric history with the expectant mother in the presence of her family or significant other. • The confidentiality of the pregnant woman must always be protected. Why?

Health History Assessment • Collect information about: • Obstetric History -- Current and past pregnancies • Menstrual History – Is there regularity? • Family history--genetic and environmental factors that affect health • Medical history-- diabetes, heart • Perform Physical Examination including a Pelvic Examination (Pap test, measurements, cervical culture) • Perform Laboratory Studies • Hgb., Hct, Type, Rh, CBC, Rubella, Hepatitis, HIV

Pelvic Measurement

Calculation of Gravida and Parity • Obstetrical Status • Gravida = number of times pregnant regardless of duration or outcome • Parity = number of deliveries after the age of viability (20 weeks). ** It is not the number of babies delivered, but the number of deliveries

Calculation of Parity • Further Breakdown into TPAL • T = Term • P = Preterm • A = Abortions • L = Living children

Check Yourself ! • The nurse obtained the following data from Mrs. Andrews. She has five year old twins that delivered at 35 weeks, a three year old son that delivered at 39 weeks, and a miscarriage last year at 12 weeks gestation. • What is her gravida and parity? • What is her gravida and parity using the TPAL system?
