Missed Preeclampsia: What the Nursing Records Show

In a missed preeclampsia case, the nursing records usually show the warning signs: elevated blood pressures in the flowsheet, a headache or visual change in a triage note, a lab result that came back abnormal. The question is what happened next. A nurse reviewer lines up every reading and symptom against the times the provider was notified and treatment was given, and the gaps between them are often the case.

Why preeclampsia is missed

Preeclampsia is a hypertensive disorder of pregnancy that usually appears after 20 weeks and can first appear after delivery, often in the days after discharge. It can progress to eclampsia (seizures), HELLP syndrome, stroke, placental abruption and organ injury. Common reasons it is missed:

• A single high reading is rechecked, the second is lower, and nothing further is done.
• Symptoms such as headache, visual changes, epigastric or right upper quadrant pain, or shortness of breath are charted but never tied to the blood pressure.
• Blood pressure is measured with the wrong cuff size or in a position that changes the reading.
• A postpartum patient comes to an emergency department that does not ask about a recent pregnancy.
• Discharge teaching does not tell the patient which symptoms mean return now.

What the standard looks like in general

ACOG guidance treats a systolic pressure of 160 or higher, or a diastolic pressure of 110 or higher, confirmed on repeat measurement, as severe-range hypertension that calls for urgent treatment. ACOG advises giving first-line medication as soon as reasonably possible, generally within 30 to 60 minutes of confirmation. Many hospitals build this into a protocol or order set, often based on national safety bundles for severe hypertension in pregnancy, with steps nurses can start. Under such protocols, nurses are generally expected to:

1. Measure correctly: the right cuff size, the patient positioned as the protocol says, and a repeat at the interval policy sets.
2. Notify the provider of severe-range readings and of symptoms, and document the time, the person notified and the response.
3. Start the protocol if the order set allows nurse initiation, and give antihypertensive medication on time once ordered.
4. Recheck blood pressure after each dose at the intervals in the protocol, and escalate if targets are not met.
5. Assess for symptoms and changes: headache, vision, pain, breathing, level of consciousness, reflexes.
6. Monitor magnesium sulfate if given for seizure prophylaxis: respiratory rate, deep tendon reflexes, urine output and level of consciousness, with calcium gluconate available, per protocol.
7. Use the chain of command if the provider does not respond or the plan does not address the readings.
8. Teach postpartum warning signs at discharge, such as AWHONN's POST-BIRTH warning signs, and document the teaching.

The facility's protocol sets its own recheck intervals and nurse-initiated orders. Get the version in effect on the dates at issue.

The records to request

• Prenatal records: baseline blood pressures, urine protein results, risk factors
• The obstetric triage record, including the acuity assigned (some units use AWHONN's Maternal Fetal Triage Index)
• The vital signs flowsheet, with every blood pressure, its time and the device, plus any readings stored by automated cuffs or monitors that were never charted
• Nursing notes describing symptoms
• Provider notification documentation and paging logs
• The MAR for antihypertensives and magnesium, with administration times and barcode scan data
• The magnesium flowsheet and intake and output records
• Lab results with collection and result times: platelets, liver enzymes, creatinine, urine protein
• Fetal monitoring strips, if the patient was still pregnant
• Discharge instructions and teaching documentation
• Postpartum contacts: emergency department and urgent care records, nurse advice line logs, patient portal messages

Building the blood pressure timeline

The core work product is a single timeline that puts every reading next to every response. A reviewer usually builds it with these columns:

Flowsheet rows can be hard to read in a printed production; how to read nursing flowsheets explains the layout. A medical chronology built on this timeline is often the exhibit the experts work from.

What a nurse reviewer finds

• Severe readings with no notification note anywhere near them.
• Notification charted, but no order and no escalation when the provider did not act.
• Medication ordered but given late, with scan data showing a later time than the charted one.
• Missing rechecks after a dose, so no one knew whether treatment worked.
• Readings explained away as pain, anxiety or a bad cuff, without a documented recheck.
• Discharge with elevated readings and no sign the provider was aware.

Postpartum presentations in the emergency department

Some of the most serious cases involve a patient who delivered days earlier and comes to an emergency department with a headache or shortness of breath. The triage nurse who does not ask about recent pregnancy may assign a low acuity and record the headache as a migraine. These cases overlap with emergency department delays, and the ED triage record, its timestamps and the waiting room reassessments belong in the same timeline.

Causation

A nurse can address recognition, notification, escalation and treatment timing. Whether earlier treatment would have prevented a stroke, eclamptic seizure or abruption needs an obstetrician or maternal-fetal medicine specialist, and often a neurologist. Patients with severe hypertension can also hemorrhage; see postpartum hemorrhage and nursing negligence for the bleeding side, and labor and delivery nursing records for the rest of the intrapartum chart. Reviewers with labor and delivery experience know these protocols from the bedside.

Next step

Request a chronology for a preeclampsia case: describe it without names, and labor and delivery nurses send proposals. Records stay private until you hire.
