A hypertensive crisis is a severe elevation of blood pressure that requires prompt assessment and management because it may lead to acute damage to vital organs. In critical care nursing, hypertensive crisis is generally considered when blood pressure is markedly elevated, often around 180/120 mmHg or higher. It may present as a hypertensive urgency, where there is severe hypertension without acute target-organ damage, or a hypertensive emergency, where severe hypertension is associated with acute damage to organs such as the brain, heart, kidneys, eyes, or aorta. Emergency management begins with rapid assessment of the patient’s airway, breathing, and circulation. The nurse should ensure airway patency, assess respiratory effort and oxygen saturation, and monitor circulation. The patient should be placed in a comfortable position, usually with the head elevated, particularly when there are neurological or respiratory symptoms. Blood pressure should be measured accurately using an appropriate cuff and repeated to confirm the reading. Both
