Preeclampsia NCLEX Questions With Answers and Rationales

Preeclampsia NCLEX questions test whether you can recognize maternal danger cues and choose the safest priority action. The key pattern is confirmed new-onset hypertension after 20 weeks of gestation in a previously normotensive client, with proteinuria or end-organ findings. On priority questions, stabilize the mother first: protect the airway and safety during seizure activity, treat severe-range blood pressure per protocol, prevent seizures with magnesium sulfate, monitor for toxicity, and prepare for delivery when indicated.

Use this practice set as NCLEX clinical judgment review, not as individualized pregnancy care advice. Answer each question first, then read the rationale and the reason the correct answer wins.

Quick NCLEX Answer

Most tested preeclampsia cue: confirmed blood pressure of 140/90 mm Hg or higher after 20 weeks of gestation, in a previously normotensive client, plus proteinuria or end-organ findings.

Severe danger cue: systolic blood pressure of 160 mm Hg or higher or diastolic blood pressure of 110 mm Hg or higher, severe headache, visual changes, right upper quadrant (RUQ) or epigastric pain, pulmonary edema, platelets below 100,000/mm3, elevated liver enzymes, renal insufficiency, decreased urine output, clonus, or seizure activity.

Priority logic: In a crisis, maternal stabilization comes before fetal assessment and delivery planning. Delivery is the definitive treatment, but the NCLEX priority is usually to control immediate maternal risks first.

Preeclampsia NCLEX Practice Questions

Question 1

A client at 32 weeks of gestation has a blood pressure of 150/96 mm Hg, 2+ protein in the urine, a persistent headache, and blurred vision. Which condition do these findings most strongly suggest?

1. Normal discomforts of pregnancy
2. Gestational diabetes
3. Preeclampsia
4. Placenta previa

Correct answer: 3. The cue pattern is hypertension after 20 weeks with proteinuria and neurologic symptoms; the blood pressure should be confirmed and escalated according to the care setting. Normal pregnancy discomforts do not explain hypertension with proteinuria. Gestational diabetes and placenta previa have different cue patterns. Why this answer wins: the stem gives the classic NCLEX recognition pattern for preeclampsia.

Question 2

Which findings are severe features of preeclampsia? Select all that apply.

1. Blood pressure 166/112 mm Hg
2. Platelet count 85,000/mm3
3. Persistent right upper quadrant pain
4. Visual spots
5. Mild ankle edema at the end of the day
6. New pulmonary edema

Correct answers: 1, 2, 3, 4, and 6. Severe-range blood pressure, platelets below 100,000/mm3, right upper quadrant or epigastric pain, visual symptoms, and pulmonary edema are severe features. Mild dependent edema alone is nonspecific in pregnancy. Why these answers win: they point to stroke risk, hepatic involvement, platelet involvement, neurologic irritability, or respiratory compromise.

Question 3

A client at 35 weeks of gestation has preeclampsia with blood pressure 170/114 mm Hg, severe headache, and clonus. Which action should the nurse anticipate first?

1. Encourage the client to ambulate to reduce edema.
2. Initiate seizure precautions and notify the obstetric team.
3. Delay care until a 24-hour urine protein result is available.
4. Teach the client about low-sodium meal planning.

Correct answer: 2. Severe-range blood pressure with headache and clonus indicates high seizure and stroke risk. The nurse should initiate seizure precautions and escalate care. Ambulation increases injury risk. Waiting for more protein data is unsafe because proteinuria is not required when severe features are present. Teaching can wait. Why this answer wins: it addresses the immediate maternal safety threat.

Question 4

A client receiving magnesium sulfate has absent deep tendon reflexes, respirations of 9/min, and urine output of 20 mL/hr. Which action is most appropriate?

1. Continue the infusion because decreased reflexes are expected.
2. Stop or hold the magnesium infusion per protocol and notify the provider.
3. Administer the next dose faster to prevent eclampsia.
4. Place the client in Trendelenburg position.

Correct answer: 2. Absent reflexes, respiratory depression, and oliguria are signs of magnesium sulfate toxicity. The nurse should stop or hold the infusion according to protocol, notify the provider, support breathing, and anticipate calcium gluconate per protocol or prescription. Why this answer wins: it prevents worsening respiratory depression and cardiac complications.

Question 5

Before continuing a magnesium sulfate infusion, which assessment is most important?

1. Food preferences
2. Respiratory rate, deep tendon reflexes, and urine output
3. Fundal height only
4. Skin turgor only

Correct answer: 2. Magnesium is cleared by the kidneys and can depress neuromuscular and respiratory function. The nurse monitors respirations, reflexes, level of consciousness, oxygenation, urine output, blood pressure, and fetal status when applicable. Why this answer wins: it checks the findings most connected to magnesium safety.

Question 6

A client with severe preeclampsia asks why magnesium sulfate is prescribed. Which response is best?

1. It lowers blood pressure as the primary antihypertensive.
2. It prevents or treats seizures associated with preeclampsia and eclampsia.
3. It increases platelet production.
4. It cures HELLP syndrome without delivery.

Correct answer: 2. Magnesium sulfate is used for seizure prevention and treatment. Severe hypertension may require medications such as IV labetalol, IV hydralazine, or oral immediate-release nifedipine depending on orders and facility protocol. Why this answer wins: it separates seizure prophylaxis from blood pressure control.

Question 7

Which medication should be readily available for a client receiving magnesium sulfate?

1. Calcium gluconate
2. Protamine sulfate
3. Vitamin K
4. Flumazenil

Correct answer: 1. Calcium gluconate is the antidote used for magnesium sulfate toxicity. Protamine reverses heparin, vitamin K reverses warfarin effects, and flumazenil reverses benzodiazepines. Why this answer wins: it matches the medication risk in the stem.

Question 8

A client with preeclampsia begins having a generalized seizure. What should the nurse do first?

1. Insert a padded tongue blade into the mouth.
2. Restrain the client's arms and legs.
3. Call for help, protect the client from injury, and maintain airway support with lateral positioning when feasible.
4. Leave the room to obtain discharge instructions.

Correct answer: 3. During an eclamptic seizure, the priority is maternal safety and airway support. Do not place objects in the mouth and do not restrain the client. After immediate safety measures, the nurse anticipates magnesium sulfate, ongoing stabilization, fetal assessment, and delivery planning. Why this answer wins: airway and injury prevention are first during active seizure activity.

Question 9

A client at 34 weeks has epigastric pain, nausea, malaise, platelets 72,000/mm3, elevated AST and ALT, and signs of hemolysis. Which complication is most consistent with these cues?

1. HELLP syndrome
2. Uncomplicated heartburn
3. Iron-deficiency anemia only
4. Hyperemesis gravidarum only

Correct answer: 1. HELLP syndrome involves hemolysis, elevated liver enzymes, and low platelets. Right upper quadrant or epigastric pain, nausea, malaise, abnormal liver enzymes, and thrombocytopenia are high-yield NCLEX cues. Why this answer wins: the labs and pain pattern show severe maternal risk, not routine pregnancy discomfort.

Question 10

A nurse is caring for four pregnant clients. Which client should be assessed first?

1. Client at 28 weeks with blood pressure 118/72 mm Hg and mild nausea
2. Client at 31 weeks with blood pressure 162/110 mm Hg and a severe headache
3. Client at 22 weeks asking about prenatal vitamins
4. Client at 30 weeks with mild ankle swelling after standing

Correct answer: 2. Severe-range blood pressure and severe headache suggest preeclampsia with severe features and risk for stroke or seizure. The other clients may need routine assessment or teaching, but they are not the priority. Why this answer wins: unstable maternal findings take priority over stable teaching needs.

Question 11

A postpartum client calls the clinic 5 days after delivery and reports a severe headache, blurred vision, shortness of breath, and home blood pressure of 164/108 mm Hg. What should the nurse instruct the client to do?

1. Rest and call back at the 6-week visit.
2. Drink more fluids and recheck the blood pressure in a week.
3. Seek emergency evaluation immediately.
4. Assume preeclampsia cannot occur after birth.

Correct answer: 3. Preeclampsia can occur postpartum, often within days and up to 6 weeks after delivery. Severe headache, visual symptoms, shortness of breath, and severe-range systolic blood pressure require urgent evaluation. Why this answer wins: postpartum status does not remove the risk of hypertensive emergency, seizure, stroke, or pulmonary edema.

Question 12

A client with preeclampsia without severe features is being discharged with instructions for home monitoring. Which statement shows correct understanding?

1. I will report severe headache, vision changes, right upper abdominal pain, shortness of breath, decreased fetal movement, or high blood pressure readings.
2. I only need to call if my feet swell at night.
3. I should stop all follow-up visits if my urine protein improves.
4. Seizures cannot happen unless I have heavy vaginal bleeding first.

Correct answer: 1. Teaching should include warning signs of worsening preeclampsia, fetal concerns, and the need for follow-up. Edema alone is nonspecific. Improved protein does not replace monitoring, and seizures can occur without vaginal bleeding. Why this answer wins: it names the symptoms that require prompt follow-up.

Question 13

Which finding in a pregnant client with hypertension most directly supports severe preeclampsia even if proteinuria is not documented?

1. New visual disturbances and platelets 90,000/mm3
2. Occasional leg cramps after exercise
3. Increased appetite
4. Mild urinary frequency with normal blood pressure

Correct answer: 1. Preeclampsia can be diagnosed with hypertension and severe features or end-organ findings even without proteinuria. Visual symptoms and thrombocytopenia are concerning. Why this answer wins: the NCLEX trap is waiting for proteinuria when severe features are already present.

Question 14

A high-risk pregnant client asks about low-dose aspirin. Which teaching is most accurate for NCLEX review?

1. Low-dose aspirin may be prescribed for prevention in selected high-risk clients, but it is not the acute treatment for severe preeclampsia.
2. Aspirin is used to stop eclamptic seizures immediately.
3. Aspirin replaces magnesium sulfate for severe features.
4. Aspirin should be started by the client without discussing it with the provider.

Correct answer: 1. ACOG and SMFM guidance supports low-dose aspirin 81 mg daily for clients at high risk or with more than one moderate-risk factor, usually started between 12 and 28 weeks, optimally before 16 weeks, and continued until delivery when prescribed. It is prevention, not acute stabilization. Why this answer wins: it keeps prevention separate from emergency treatment.

Question 15

A client with severe preeclampsia at 35 weeks asks why the team is not taking the client for immediate cesarean birth before treating the blood pressure and seizure risk. Which explanation is best?

1. Delivery is never used for preeclampsia.
2. Maternal stabilization is the priority before delivery planning when the client is unstable.
3. Fetal assessment is always more important than maternal airway and circulation.
4. Proteinuria must be corrected before any other action.

Correct answer: 2. Delivery is the definitive treatment for preeclampsia, but severe maternal instability requires stabilization first. The nurse focuses on airway, breathing, circulation, seizure prevention, blood pressure control, and preparation for delivery. Why this answer wins: the mother is the resuscitation priority, and fetal status depends on maternal stability.

Question 16

Which order should the nurse question for a client actively seizing from suspected eclampsia?

1. Administer oxygen as needed.
2. Place the client in a lateral position when possible.
3. Insert an object into the client's mouth during the seizure.
4. Administer magnesium sulfate per protocol.

Correct answer: 3. Objects should not be placed into the mouth during a seizure because they can cause injury or obstruct the airway. Oxygen, lateral positioning, and magnesium sulfate are appropriate parts of emergency management. Why this answer wins: it identifies the unsafe seizure intervention.

Next Gen NCLEX Preeclampsia Case Study

A 29-year-old G1P0 client at 34 weeks of gestation arrives with a severe headache, blurred vision, epigastric pain, and decreased fetal movement. Blood pressure is 168/112 mm Hg. Urine protein is 3+. Deep tendon reflexes are brisk with clonus. Platelets are 92,000/mm3, AST and ALT are elevated, and creatinine is 1.2 mg/dL. Fetal tracing is category II.

Question 17: Recognize Cues

Which assessment findings require immediate follow-up? Select all that apply.

1. Blood pressure 168/112 mm Hg
2. Blurred vision
3. Epigastric pain
4. Platelets 92,000/mm3
5. Decreased fetal movement
6. Client is 34 weeks pregnant

Correct answers: 1, 2, 3, 4, and 5. Severe-range blood pressure, visual symptoms, epigastric pain, thrombocytopenia, and decreased fetal movement are concerning. Gestational age provides context but is not itself the abnormal cue. Why these answers win: they identify maternal severe features and possible fetal compromise.

Question 18: Analyze Cues

Based on the case, which condition is most concerning?

1. Preeclampsia with severe features and possible HELLP syndrome
2. Uncomplicated nausea of pregnancy
3. Normal late-pregnancy swelling
4. Postpartum preeclampsia

Correct answer: 1. Severe-range blood pressure, headache, visual symptoms, epigastric pain, clonus, low platelets, elevated liver enzymes, and creatinine above 1.1 mg/dL support preeclampsia with severe features and possible HELLP syndrome. The client is antepartum, not postpartum. Why this answer wins: it connects the cue cluster to the highest-risk maternal problem.

Question 19: Prioritize Actions

Which actions should the nurse anticipate? Select all that apply.

1. Initiate seizure precautions.
2. Administer magnesium sulfate as prescribed.
3. Treat severe blood pressure per protocol as prescribed.
4. Continue maternal and fetal monitoring.
5. Prepare for delivery after maternal stabilization.
6. Encourage independent ambulation to reduce edema.

Correct answers: 1, 2, 3, 4, and 5. The client needs seizure precautions, magnesium sulfate, severe blood pressure treatment, close maternal-fetal monitoring, and delivery planning after stabilization. Ambulation is unsafe with severe features and seizure risk. Why these answers win: they match the priority chain: stabilize mother, monitor fetus, prepare for delivery.

Question 20: Bow-Tie Style

Complete the clinical judgment pattern.

Rationale: This client has neurologic, hepatic, renal, hematologic, and fetal warning cues. The safest plan controls maternal seizure and stroke risk while monitoring for magnesium toxicity and fetal compromise.

Question 21: Ordered Response

Place the nursing priorities in the best order for the unstable client in the case.

1. Assess airway, breathing, circulation, level of consciousness, and seizure risk.
2. Call for help and notify the obstetric team.
3. Initiate seizure precautions and administer magnesium sulfate as prescribed.
4. Treat severe-range blood pressure per protocol as prescribed.
5. Prepare for delivery or transfer after maternal stabilization.

Correct order: 1, 2, 3, 4, 5. The nurse first assesses immediate physiologic risk, activates help, prevents or treats seizures, supports urgent blood pressure control, and prepares for delivery once the mother is stabilized. Why this order wins: it protects maternal airway, brain, and circulation before definitive delivery planning.

High-Yield Preeclampsia Review For NCLEX

Preeclampsia vs Eclampsia vs HELLP

Magnesium Sulfate Nursing Considerations

Magnesium sulfate is one of the most important preeclampsia medications for NCLEX because it is tied to both seizure prevention and toxicity monitoring. The nurse should know why it is used, what to assess before and during infusion, and what findings require follow-up.

• Purpose: prevent or treat eclamptic seizures.
• Not the purpose: primary control of severe hypertension.
• Monitor: respiratory rate, oxygen saturation, level of consciousness, deep tendon reflexes, clonus, urine output, blood pressure, and fetal status if antepartum or intrapartum.
• Toxicity cues: absent reflexes, respiratory depression, oliguria, marked sedation, and worsening mental status.
• Antidote: calcium gluconate should be available according to facility protocol.

Delivery And Prioritization Rules

Delivery is the definitive treatment for preeclampsia, but timing depends on gestational age, maternal status, fetal status, and severity. For NCLEX purposes, preeclampsia or gestational hypertension without severe features is commonly associated with delivery at 37 weeks or later. Preeclampsia with severe features is commonly associated with delivery at 34 weeks or later after maternal stabilization, or earlier if maternal or fetal status deteriorates.

The safest test-taking rule is this: unstable maternal findings come first. During an active seizure, protect the client, support airway and breathing, call for help, and anticipate magnesium sulfate. With severe-range blood pressure, anticipate urgent antihypertensive therapy per protocol. Fetal assessment matters, but fetal well-being depends on maternal oxygenation, circulation, and seizure control.

Common NCLEX Traps

• Waiting for proteinuria: severe features or end-organ findings can make the situation urgent even when proteinuria is not documented.
• Calling magnesium sulfate an antihypertensive: magnesium is for seizure prevention and treatment.
• Choosing delivery before stabilization: delivery may be needed, but airway, breathing, circulation, seizure control, and severe BP treatment come first in an unstable client.
• Ignoring postpartum symptoms: preeclampsia can occur after delivery.
• Minimizing RUQ or epigastric pain: this can signal liver involvement or HELLP syndrome.
• Using unsafe seizure actions: do not restrain the client and do not place objects in the mouth.

FAQs

What is the priority nursing action for preeclampsia on the NCLEX?

The priority depends on the cue. Severe-range blood pressure, headache, visual changes, clonus, shortness of breath, RUQ pain, low platelets, or abnormal labs require prompt escalation. In general, the nurse prioritizes maternal stabilization, seizure precautions, magnesium sulfate when prescribed, urgent blood pressure treatment per protocol, and fetal monitoring.

What is the priority during an eclamptic seizure?

Protect the client from injury, call for help, support airway and oxygenation, and position laterally when feasible. Do not restrain the client and do not place anything in the mouth. After immediate safety actions, anticipate magnesium sulfate and continued stabilization.

Does preeclampsia always require proteinuria?

No. NCLEX questions may show confirmed hypertension after 20 weeks with severe features even without proteinuria. Do not delay action when the stem gives severe headache, visual changes, pulmonary edema, low platelets, renal insufficiency, elevated liver enzymes, or severe-range blood pressure.

What blood pressure is severe preeclampsia?

Severe-range blood pressure is generally systolic 160 mm Hg or higher or diastolic 110 mm Hg or higher. On NCLEX questions, this is urgent because of maternal stroke and seizure risk, especially when symptoms such as headache, visual changes, or clonus are present.

Is magnesium sulfate an antihypertensive?

No. Magnesium sulfate is used to prevent or treat seizures in severe preeclampsia and eclampsia. Severe hypertension may require medications such as labetalol, hydralazine, or immediate-release nifedipine when prescribed and appropriate.

What should the nurse monitor during magnesium sulfate therapy?

Monitor respiratory rate, oxygen saturation, deep tendon reflexes, level of consciousness, urine output, blood pressure, and fetal status when applicable. Absent reflexes, respiratory depression, oliguria, and decreased level of consciousness suggest possible toxicity and require immediate follow-up.

What is the antidote for magnesium sulfate toxicity?

Calcium gluconate is the antidote associated with magnesium sulfate toxicity. It should be available according to facility protocol when a client is receiving magnesium sulfate.

When is delivery indicated for preeclampsia?

Delivery is the definitive treatment, but timing depends on severity, gestational age, fetal status, and maternal stability. Common NCLEX framing is delivery at 37 weeks or later for preeclampsia without severe features, delivery at 34 weeks or later for severe features after stabilization, and earlier delivery for deterioration such as eclampsia, HELLP syndrome, abruption, disseminated intravascular coagulation (DIC), uncontrolled severe hypertension, worsening organ function, or nonreassuring fetal status.

What is HELLP syndrome on NCLEX questions?

HELLP stands for hemolysis, elevated liver enzymes, and low platelets. NCLEX stems may include RUQ or epigastric pain, nausea, malaise, low platelets, abnormal AST or ALT, and hemolysis clues. Treat it as a severe maternal complication that requires prompt escalation.

Can preeclampsia happen after delivery?

Yes. Postpartum preeclampsia can occur after birth, most often within a few days and up to 6 weeks after delivery. Postpartum clients should report severe headache, visual changes, RUQ or epigastric pain, shortness of breath, chest pain, severe nausea or vomiting, seizure activity, high blood pressure readings, sudden swelling, or neurologic symptoms.
