Study Notes

Estimating Due Date

Last Menstrual Period (LMP) is the starting point for calculating the estimated due date (EDD).
Nagele’s Rule steps:
- Subtract 3 months from the LMP.
- Add 7 days.
- Add 1 year.
Example: LMP on 1/1/23 leads to an EDD of 10/8/24 after calculations.

Obstetric Terms

Gravid: State of being pregnant.
Gravida/Gravidity: Total number of pregnancies, including terminations and multiple births; multiple gestation counts as one pregnancy.
Nulligravida: Woman with no previous pregnancies.
Primigravida: Woman pregnant for the first time.
Secundigravida: Woman pregnant for the second time.
Multigravida: Woman pregnant for the third time or more.
Para: Number of births after 20 weeks gestation, regardless of outcomes; multiple births count as one.
Nullipara: Woman who has not had a viable birth (≥20 weeks).
Primipara: Woman with one birth after 20 weeks.
Multipara: Woman with two or more births after 20 weeks.

Preconception and Interconception Care

Aim: Optimize health and well-being prior to pregnancy to improve outcomes and reduce problems.
Focus areas:
- Immunization status.
- Pre-existing medical conditions.
- Reproductive healthcare practices.
- Nutrition and lifestyle.
- Psychosocial issues.
- Medication and drug use.
Identifying risks like alcohol misuse, certain drugs, diseases (e.g., diabetes, STD), obesity, and nutritional deficiencies (e.g., folic acid).

First Prenatal Visit Components

Comprehensive health history.
Physical examination.
Laboratory tests.

Comprehensive Health History

Main areas of inquiry:
- Reason for care: Suspecting pregnancy, last menstrual period date, pregnancy signs, and hCG testing.
- History: Medical, surgical, family histories.
- Reproductive history: Menstrual cycle, obstetric background, gynecological history.
Estimating EDD is critical for prenatal care and involves:
- Guidance for maternal/fetal tests.
- Tracking fetal growth.
- Planning specific interventions for complications.
Ultrasound is the most reliable method for determining EDD.

Importance of Estimated Due Date

Establishing the estimated date of confinement (EDC) is essential for monitoring and managing the pregnancy effectively.
Nagele's Rule is a valuable tool for calculating EDC based on LMP.
