🩺
📒 The 1-minute cheat sheet
📌 Define
SBP > 180 or DBP > 120
Emergency = organ damage
🩺 Signs
Severe HA, blurred vision
Chest pain, dyspnea
Confusion, seizures, stroke
✅ Do
IV nitroprusside/labetalol
Lower BP slowly (25% in 1h)
Continuous BP + cardiac monitor
📌 Avoid
Too-rapid drop → ischemia
📚 Hypertensive Crisis — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Hypertensive crisis is a severe elevation in blood pressure, typically systolic over 180 mmHg and/or diastolic over 120 mmHg, that can damage organs. A hypertensive emergency includes acute target-organ damage (brain, heart, kidneys, eyes) and requires immediate, controlled BP lowering. Common precipitants include medication nonadherence and abrupt withdrawal of antihypertensives.
🔑
Key points
Understand these first
Defined as systolic over 180 mmHg and/or diastolic over 120 mmHg.
Hypertensive emergency = severe BP WITH acute organ damage; urgency = severe BP WITHOUT acute damage.
Common cause is abrupt stopping or nonadherence to antihypertensive medication.
Target-organ damage includes stroke, encephalopathy, MI, heart failure, aortic dissection, and acute kidney injury.
IV antihypertensives (e.g., nicardipine, labetalol, nitroprusside) are used in emergencies with continuous monitoring.
BP must be lowered gradually — typically no more than about 25% in the first hour — to avoid organ hypoperfusion.
✅
Nursing priorities
What to do, in order
Establish continuous BP monitoring (often arterial line) and frequent neuro/cardiac assessment.
Administer IV antihypertensives via pump and titrate carefully per protocol.
Lower BP gradually to prevent cerebral, cardiac, or renal hypoperfusion.
Never abruptly stop antihypertensive medications — take them consistently.
Monitor blood pressure at home and keep follow-up appointments.
Report severe headache, chest pain, vision changes, or shortness of breath immediately.
Limit sodium, manage stress, avoid stimulants, and adhere to lifestyle changes.
❓ Hypertensive Crisis: NCLEX FAQs
What are the priority nursing interventions for Hypertensive Crisis?
Establish continuous BP monitoring (often arterial line) and frequent neuro/cardiac assessment. Administer IV antihypertensives via pump and titrate carefully per protocol. Lower BP gradually to prevent cerebral, cardiac, or renal hypoperfusion. Assess for target-organ damage: neuro changes, chest pain, dyspnea, vision changes, urine output.
What are the warning signs of Hypertensive Crisis a nurse must report?
Severe headache, confusion, visual changes, or focal weakness suggest stroke/encephalopathy — emergency. Tearing chest/back pain with a BP difference between arms may indicate aortic dissection. Chest pain, dyspnea, or decreasing urine output signals cardiac/renal injury. Dropping BP too fast can cause ischemic stroke or MI from hypoperfusion.
What do I need to know about Hypertensive Crisis for the NCLEX?
Defined as systolic over 180 mmHg and/or diastolic over 120 mmHg. Hypertensive emergency = severe BP WITH acute organ damage; urgency = severe BP WITHOUT acute damage. Common cause is abrupt stopping or nonadherence to antihypertensive medication. Target-organ damage includes stroke, encephalopathy, MI, heart failure, aortic dissection, and acute kidney injury.
What patient teaching is important for Hypertensive Crisis?
Never abruptly stop antihypertensive medications — take them consistently. Monitor blood pressure at home and keep follow-up appointments. Report severe headache, chest pain, vision changes, or shortness of breath immediately. Limit sodium, manage stress, avoid stimulants, and adhere to lifestyle changes.
