Objectives of Antenatal Care

• Ensure a healthy mother and newborn
• Estimate gestational age and expected date of delivery
• Identify high-risk pregnancies
• Detect and treat diseases during pregnancy
• Detect congenital fetal malformations
• Educate patients and prepare them for childbirth

Elements of Antenatal Care

• History taking
• Physical examination
• Investigations (routine and screening tests)
• Plan schedule for return visits
• Instructions and advice
• Reassurance
• Plan for delivery
• Documentation
