A 28-year-old multigravida (G3P2L2) from urban Delhi presents at 32 weeks of gestation for her third antenatal visit. She reports good adherence to iron-folic acid supplementation and has received TT Dose 1 at 16 weeks and TT Dose 2 at 20 weeks. On examination, blood pressure is 128/82 mmHg, weight gain is appropriate, and urine shows no proteinuria. She has no symptoms of gestational diabetes. According to the comprehensive antenatal care package, which of the following is the MOST appropriate action at this visit?

Explanation

## Antenatal Care Package at 32 Weeks Gestation (Third Trimester) ### Third Trimester Visit Components **Key Point:** At 32 weeks (third trimester), the focus shifts to maternal monitoring for complications, fetal well-being assessment, and preparation for labour and delivery. TT booster vaccination, if indicated, is completed in the third trimester. ### Timeline of TT Immunization in Pregnancy | Dose | Timing | Protection Duration | |---|---|---| | TT Dose 1 | First visit (≤16 weeks) | — | | TT Dose 2 | 4 weeks after Dose 1 (~20 weeks) | Protective immunity achieved | | TT Booster | If last TT >5 years ago OR if only 1 dose in pregnancy | Reinforces immunity | **High-Yield:** In India, if a woman has received 2 TT doses during pregnancy (as in this case), she is fully protected. However, if she had not received TT in the preceding 5 years, a booster may be considered in the third trimester for additional assurance. The current guideline emphasizes that 2 doses during pregnancy provide adequate protection. ### Third Trimester Antenatal Care Package (28–40 weeks) **Clinical Pearl:** The third trimester visit at 32 weeks typically includes: 1. **Vital signs monitoring** — Blood pressure, weight, urine examination (screen for preeclampsia, gestational proteinuria) 2. **Fetal assessment** — Abdominal examination, fundal height, fetal movements, presentation (by 36 weeks) 3. **Maternal counselling** — Danger signs in pregnancy (vaginal bleeding, severe headache, visual disturbances, epigastric pain, reduced fetal movements), birth preparedness, and newborn care 4. **TT booster** (if indicated by history) 5. **Anemia assessment** — Repeat Hb if indicated 6. **Fetal well-being** — Cardiotocography is NOT routine at 32 weeks in uncomplicated pregnancies; it is reserved for high-risk cases or third trimester complications **Mnemonic:** **THIRD** — **T**etanus booster (if needed), **H**ypertension screening, **I**nformation on danger signs, **R**outine vitals, **D**anger sign counselling and birth preparedness. ### Why Other Interventions Are Inappropriate - **Repeat OGTT:** GDM screening is done once at 24–28 weeks. Repeat testing is not indicated unless the first test was abnormal or the patient is high-risk. - **Antihypertensive therapy:** BP of 128/82 mmHg is elevated but does not meet criteria for hypertension in pregnancy (≥140/90 mmHg for Stage 1). No proteinuria is present, so preeclampsia is not diagnosed. Antihypertensive therapy is not indicated. - **Cardiotocography (CTG):** Routine CTG at 32 weeks is not recommended in uncomplicated pregnancies. It is indicated in high-risk pregnancies or if there are signs of fetal compromise. - **Prophylactic antibiotics:** Not indicated in uncomplicated pregnancy at 32 weeks; used only for specific indications (e.g., GBS colonization near term, or in preterm labour).
