Study Notes
Antepartum Care Overview
- Initial prenatal visit recommended at 6-8 weeks for risk assessment and health promotion.
- Gather comprehensive history, including chronic medical issues, previous pregnancies, genetic screenings, and psychosocial history.
Estimation of Delivery
- Estimated date of delivery (EDD) calculated as 40 weeks from the last menstrual period (LMP) for regular 28-day cycles.
Prenatal Visits
- Regular visits monitor weight, blood pressure, fetal measurements, and overall health.
- Diabetes screening involves an oral glucose test at 24-28 weeks; for obese women, testing occurs at the first visit.
- Fetal heart rate can be detected as early as 12 weeks.
- Ultrasound for fetal survey performed between 18-24 weeks.
Fetal Monitoring and Movement
- Nonstress test assesses fetal heart rate patterns and accelerations over at least 20 minutes.
- Maternal kick counts recommend observing for 5 movements in 1 hour or 10 movements in 2 hours.
Maternal Health Considerations
- Fundal height and amniotic fluid volume are measured during prenatal visits.
- Respiratory system is the last to develop in the fetus.
- Folic acid supplementation should be 0.4 mg daily; 4 mg daily for those with neurotube defects.
Weight Gain Recommendations
- Pre-pregnancy BMI under 29 allows for a weight gain of 11-20 lbs.
Dietary Restrictions
- Avoid consumption of cold lunch meats and unpasteurized dairy products.
- Moderate exercise and sexual activity are generally permitted; travel up to 36 weeks is acceptable with breaks every 1-2 hours.
Medication and Health Precautions
- Avoid certain medications such as ACE inhibitors, Coumadin, and retinoids.
- Emphasize shared decision-making and patient education during all visits.
Initial Prenatal Visit Components
- Initial visit often occurs around 10 weeks, with a thorough history and physical exam similar to preconception visits.
- Full head-to-toe examination includes vital signs, HEENT, cardiovascular, respiratory, abdomen, musculoskeletal, neurological, gynecological evaluations.
Laboratory Tests During Initial Visit
- Blood tests include CBC with differential, blood type and Rh factor, antibody screen, and infectious disease screening (e.g., HIV, Hepatitis B).
- Urinalysis and cultures for urinary tract infections and sexually transmitted infections.
Additional Testing Based on History
- Diabetes screening for individuals with BMI over 25 and risk factors relating to diabetes.
- TSH levels checked for thyroid disorders; additional genetic and cancer screenings if needed.
- Varicella immunity confirmed if vaccination history is unclear.
Dating the Pregnancy
- Determining EDD based on LMP using Naegel’s rule: add 7 days to LMP, subtract 3 months, adjusting days for different months.
- Demonstrates uterine size progression from nonpregnant to 12 weeks, described as varying fruit sizes.
Example Calculation
- If LMP is May 3, 2024, EDD would be calculated accordingly.
