Prenatal care, commonly referred to as antenatal care (ANC), encompasses the comprehensive medical and nursing supervision given to a pregnant woman from conception until the onset of labor. The primary aim is to monitor the normal progression of pregnancy and promote the health of both mother and fetus. Safe motherhood initiatives depend heavily on accessible, quality antenatal services, particularly in resource-limited settings across Nigeria where maternal mortality remains a major public health challenge. Nurses serve as the frontline educators, screeners, and coordinators of this care, establishing vital trust and continuity for expectant mothers.
Structured antenatal visits are scheduled to detect and manage potential complications early. The World Health Organization recommends a minimum of eight contacts for a positive pregnancy experience, replacing the older four-visit model.
Key objectives include screening for pre-eclampsia, managing anemia, administering tetanus toxoid vaccination, and providing malaria prophylaxis.
Pregnancy induces profound anatomical and physiological adaptations across every body system to accommodate the growing fetus.
The initial antenatal booking visit requires a meticulous history and physical examination. The nurse must gather biographical data, medical history, surgical history, family history, and a detailed obstetric history summarized using the TPAL or GPA system (Gravida, Para, Abortion). Obstetric history must explore past labor complications, postpartum hemorrhages, or previous cesarean sections. The physical examination includes baseline vital signs, weight, height, systemic examination, and an abdominal examination to estimate gestational age via fundal height measurement once past 20 weeks.
Routine laboratory investigations are essential screening tools during early and subsequent antenatal visits.
| Test | Purpose | Timing |
|---|---|---|
| Hemoglobin / PCV | Screen for baseline anemia | Booking and 28-32 weeks |
| Urinalysis | Detect protein, glucose, and infection | Every visit |
| Blood Group & Genotype | Identify Rhesus incompatibility and sickle cell trait | Booking visit |
| Serology (HIV, VDRL, HBsAg) | Screen for vertical transmission infections | Booking visit |
Midwifes and nurses must review these results promptly to institute timely interventions, such as administering anti-D immunoglobulin to Rhesus-negative mothers.
Adequate nutrition supports fetal development and maternal tissue expansion. Pregnant women require an increase in daily caloric intake, balanced across carbohydrates, proteins, and healthy fats. Standard antenatal supplementation includes folic acid in the first trimester to prevent neural tube defects, and iron and folate combinations thereafter to prevent anemia. Health promotion must also cover safe water consumption, adequate rest, avoidance of self-medication, and the use of insecticide-treated bed nets to prevent malaria.
Nurses must remain vigilant in identifying danger signs that signal severe obstetric complications. Any high-risk condition—such as multiple gestation, malpresentation, severe hypertension, vaginal bleeding, or severe abdominal pain—demands prompt escalation or referral to a higher-level facility.
Birth preparedness and complication readiness (BPCR) is a strategy aimed at reducing delays in obtaining emergency obstetric care. Every pregnant woman and her family must make concrete plans before labor begins. This involves identifying a skilled birth attendant, choosing a health facility, arranging emergency transport, securing funds for potential medical costs, and identifying a compatible blood donor if needed. Nurses guide families through these plans to ensure swift action when labor starts or if a life-threatening emergency occurs.
