Postpartum Hypertension with Worsening Headache on Day 3
A 34-year-old G2P2 delivered vaginally 3 days ago after an uncomplicated pregnancy. She was discharged yesterday with BP 132/84. Today she returns to triage with a severe frontal headache that has worsened over 6 hours, blurred vision, and nausea. BP is 168/108 on two readings 15 minutes apart. Reflexes are 2+ and symmetric; she has 1+ proteinuria on dipstick. She reports swelling in her hands and face that she did not have at discharge. Platelets were 210,000 at delivery; today they are 98,000. AST is 88, ALT is 76. She is breastfeeding and asks whether she can continue. Fetal/newborn status is not relevant here; the infant is at home with family.
1. What is your assessment and immediate plan?

This is postpartum preeclampsia with severe features - severe-range BP (168/108), headache, visual changes, nausea, edema, thrombocytopenia (98,000), and elevated transaminases. Onset after discharge is common and can occur up to 6 weeks postpartum.
Immediate plan:
- Notify the provider immediately and initiate a severe hypertension protocol.
- Antihypertensives: administer rapid-acting agents per protocol (e.g., IV labetalol, hydralazine, or oral nifedipine) to bring BP below severe range, typically within 30-60 minutes. Recheck BP every 10-15 minutes after each dose.
- Magnesium sulfate: initiate for seizure prophylaxis given severe features (headache, visual changes, thrombocytopenia, elevated liver enzymes). Monitor reflexes, respiratory rate, urine output, and mental status.
- Labs: repeat CBC, platelets, AST/ALT, creatinine, and urine protein; monitor trends.
- Continuous monitoring: maternal vital signs, fetal status not applicable, but monitor for signs of HELLP syndrome and pulmonary edema.
- Safety: fall precautions, seizure precautions, quiet environment, and IV access.
- Communication: explain the diagnosis and plan to the mother; she is frightened and needs clear information.
2. The mother asks whether she can continue breastfeeding and whether the medications are safe. How do you respond?
Read the worked answer
Breastfeeding is generally compatible with postpartum preeclampsia treatment:
- Magnesium sulfate: small amounts pass into breast milk; it is generally considered compatible with breastfeeding. Monitor the infant for sedation or feeding changes, but it is not a reason to stop.
- Labetalol: considered compatible with breastfeeding; low levels in milk.
- Nifedipine: considered compatible; commonly used in lactation.
- Hydralazine: considered compatible.
- Methyldopa: generally avoided in breastfeeding due to concerns about infant sedation and other effects; not first-line here.
Nursing response: reassure the mother that she can continue breastfeeding, explain that the medications are commonly used in breastfeeding mothers, and encourage her to pump or feed as she is able. If she is too ill to feed, support pumping and storage. Provide lactation consultation and involve the provider in medication selection. Document the teaching and her understanding.
3. Twelve hours later her BP is 156/96, platelets are 88,000, and she reports right upper quadrant pain. What is your concern and what do you do?

RUQ pain with thrombocytopenia and elevated liver enzymes suggests HELLP syndrome (hemolysis, elevated liver enzymes, low platelets) and possible hepatic involvement. This is an obstetric emergency.
Actions:
- Notify the provider immediately and escalate to the obstetric team.
- Continue magnesium sulfate for seizure prophylaxis; monitor closely.
- Repeat labs: CBC, platelets, AST/ALT, LDH, haptoglobin, bilirubin, and creatinine; monitor for hemolysis.
- Assess for hepatic rupture or hematoma: severe RUQ or epigastric pain, shoulder pain, hypotension, and tachycardia warrant urgent imaging and surgical consultation.
- BP management: continue antihypertensives to keep BP below severe range.
- Prepare for possible transfer to a higher level of care or ICU if the patient deteriorates.
- Fluid balance: monitor intake and output; avoid fluid overload.
- Communication: keep the mother and family informed; explain the need for close monitoring.
- Documentation: timeline, notifications, interventions, and responses.
