HELLP Syndrome nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
HELLP syndrome nursing care starts with recognising right upper quadrant or epigastric pain in a pregnant or postpartum patient as a liver and clotting emergency, not indigestion. Priorities are seizure precautions, strict blood pressure and neuro monitoring, urgent liver enzyme and platelet trending, and preparing for expedited delivery, since HELLP resolves only once the pregnancy ends.
Recognising it at the bedside
A patient at 28 to 36 weeks reports right upper quadrant or epigastric pain, nausea and malaise that she describes as flu-like or as heartburn that will not settle with antacids. She may have no headache, no visual changes and a blood pressure that is only mildly elevated. That combination is exactly why HELLP gets missed on a first pass.
Look past the vague complaint to the triad the name spells out: haemolysis, elevated liver enzymes, low platelets. Bruising at IV sites, petechiae, or oozing from venepuncture sites are visible clues to the platelet drop. Dark urine and scleral jaundice point to haemolysis. Ask directly about right upper quadrant pain in any pregnant patient past 20 weeks who presents unwell, even without hypertension on the chart.
Why the classic presentation misleads
Nursing education anchors preeclampsia to hypertension and proteinuria, so a patient with a blood pressure of 138/88 and 1+ proteinuria reads as reassuring. In HELLP, up to 15 to 20% of patients have minimal or no hypertension at diagnosis, and the liver and haematological picture can be severe while the blood pressure looks unremarkable.
The abdominal pain is the trap. Right upper quadrant pain in the third trimester is triaged toward gallbladder disease, gastritis, or round ligament strain far more often than toward a pregnancy-specific liver process. That default triage costs time HELLP does not forgive, because hepatic swelling from HELLP can progress to subcapsular haematoma and rupture. Treat new right upper quadrant or epigastric pain in pregnancy as HELLP until labs say otherwise.
Priority nursing actions
Get IV access, send a full preeclampsia panel, and place the patient on continuous fetal monitoring and frequent maternal vital signs. Seizure precautions apply even without reported hypertension, because HELLP sits on the severe end of the preeclampsia spectrum and can progress to eclampsia quickly.
If magnesium sulfate is ordered for seizure prophylaxis, monitor deep tendon reflexes, respiratory rate and urine output before each bolus and hourly during infusion, and keep calcium gluconate at the bedside as the antidote. Watch bleeding precautions given the platelet count: minimise venepunctures, avoid intramuscular injections, and use a soft toothbrush and razor precautions if the patient is admitted for more than a day. Notify the provider immediately for platelets trending under 100,000, worsening right upper quadrant pain, or any sign of altered mental status, since these change the urgency of delivery planning.
Labs and diagnostics to expect
Expect a full haemolysis, liver and coagulation workup ordered together: complete blood count with platelets, peripheral smear for schistocytes, lactate dehydrogenase, haptoglobin, AST and ALT, bilirubin, and a coagulation panel if bleeding is a concern. Platelets under 100,000/microlitre, AST or ALT roughly double the upper limit of normal, and an elevated LDH with low haptoglobin together confirm the diagnosis.
Repeat labs are drawn frequently, often every 6 to 12 hours, because HELLP can deteriorate within hours. A right upper quadrant ultrasound is used if subcapsular haematoma is suspected. Track the trend, not just the single value; a platelet count dropping from 140,000 to 90,000 over two draws is more urgent than a stable count sitting at 95,000.
Complications and their early signs
The complication that separates HELLP from routine preeclampsia is hepatic: subcapsular haematoma or liver rupture. Sudden, severe right upper quadrant pain with shoulder tip pain, hypotension and tachycardia is a surgical emergency and should trigger an immediate provider call, not a wait-and-reassess.
Disseminated intravascular coagulation follows from the platelet consumption and can present as oozing from IV sites, gum bleeding, or heavy vaginal bleeding out of proportion to labour. Pulmonary oedema and acute kidney injury also occur, so track fluid balance and urine output closely, particularly if magnesium sulfate is running. Placental abruption is another feared complication; sudden, constant abdominal pain with a rigid uterus or vaginal bleeding needs immediate escalation and continuous fetal monitoring.
Teaching that changes outcomes
Delivery is the only cure for HELLP, so counsel the patient early that treatment is aimed at stabilising her and the fetus for expedited birth rather than curing the condition while pregnant. This reframes what can otherwise feel like an alarming shift from a low-risk pregnancy to an urgent delivery plan.
Teach her to report right upper quadrant pain, headache, visual changes or swelling immediately rather than waiting for the next scheduled visit, since HELLP can develop between antenatal appointments. For postpartum patients, explain that HELLP can present or worsen up to 48 hours after birth, so the same symptoms warrant an urgent call even after discharge. Reassure her that platelets and liver enzymes typically normalise within days of delivery, but that recovery is monitored with repeat labs before she is cleared.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our maternity and newborn practice questions are the closest set to what this page covers.
Common questions
Can HELLP syndrome occur without high blood pressure?
Yes. A notable proportion of patients with HELLP have normal or only mildly elevated blood pressure at diagnosis. Relying on hypertension alone to trigger suspicion will miss these patients, so right upper quadrant pain, malaise or lab abnormalities should be treated as red flags on their own.
What is the priority nursing intervention for a patient with suspected HELLP syndrome?
Institute seizure precautions and get a full preeclampsia lab panel sent immediately, alongside continuous fetal and maternal monitoring. Rapid identification of the platelet count and liver enzymes drives the urgency of the delivery decision.
How is HELLP syndrome different from preeclampsia?
HELLP is considered a severe variant of preeclampsia, defined by haemolysis, elevated liver enzymes and low platelets rather than by blood pressure and proteinuria alone. It carries a higher risk of hepatic and haematological complications and can develop rapidly.
Can HELLP syndrome develop after delivery?
Yes, HELLP can present or worsen in the postpartum period, typically within 48 hours of birth. Any postpartum patient reporting right upper quadrant pain, headache or visual disturbance needs the same urgent workup as an antenatal patient.
What NCLEX-style priorities come up most for HELLP syndrome?
Expect questions testing recognition of right upper quadrant pain as a HELLP symptom rather than gallbladder disease, prioritisation of seizure precautions and magnesium sulfate monitoring, and identification of falling platelets or rising liver enzymes as the trigger for escalation.
