How is severe preeclampsia defined?

Severe preeclampsia is characterized by specific criteria that indicate significant health risks for both the mother and the fetus. The correct application of these criteria involves understanding blood pressure thresholds alongside accompanying symptoms or complications.

When it comes to severe preeclampsia, the defining characteristic is blood pressure measurements greater than 160/110 mmHg combined with either significant proteinuria or signs of end-organ dysfunction. This classification is critical because it helps healthcare providers identify cases that may require immediate medical intervention to prevent severe complications, such as eclampsia or maternal organ failure. The presence of proteinuria and/or end-organ dysfunction indicates that the disease process is affecting not only the blood pressure but also the overall health of the maternal body.

Other choices either do not meet the criteria for severe preeclampsia or describe different stages or related conditions. For example, blood pressure readings greater than 140/90 mmHg do not specify the severity required for the diagnosis of severe preeclampsia, whereas blood pressure above 130/80 mmHg is too vague and does not coincide with the diagnostic criteria for this condition. Similarly, blood pressure measurements that fall between 140/90 mmHg and 160/110 mmHg may indicate mild hypertension
