Station 8 — Antenatal Care: Maternal Health Chart and WHO Visit Schedule
🎯 Candidate Task
Identify the mother-and-child-health chart provided at the station. State the recommended antenatal-care contact schedule for an uncomplicated pregnancy according to WHO criteria.
⚡ Model Station Answer
- Identification: This is a mother-and-child-health record/chart used to document and follow maternal and fetal care during pregnancy.
- WHO recommendation: A minimum of 8 antenatal contacts is recommended for an uncomplicated pregnancy.
- Schedule: First contact by 12 weeks, followed by contacts at 20, 26, 30, 34, 36, 38 and 40 weeks.
- The chart should be updated at each contact so that maternal and fetal progress can be followed longitudinally.
🔎 How to Perform / Approach
- Step 1 — Identify the chart.
Recognize it as a mother-and-child-health or antenatal record containing maternal, pregnancy and follow-up information. - Step 2 — Confirm pregnancy details.
Look for relevant identifiers such as gestational age, expected date of delivery and previous antenatal entries. - Step 3 — Recall the WHO model.
State that WHO recommends a minimum of 8 antenatal contacts rather than the older four-visit model. - Step 4 — First trimester.
Arrange the 1st contact by 12 weeks of gestation. - Step 5 — Second trimester.
Arrange the 2nd contact at 20 weeks and the 3rd at 26 weeks. - Step 6 — Third trimester.
Arrange contacts at 30, 34, 36, 38 and 40 weeks. - Step 7 — Document and individualize.
Record each contact on the maternal-health chart and arrange additional assessment when maternal or fetal risk requires closer follow-up.
Easy recall: 12 → 20 → 26 → 30 → 34 → 36 → 38 → 40 weeks
Exam wording: WHO uses the term “contact” rather than simply “visit” because antenatal care should involve active assessment, support and communication between the woman and healthcare provider.
