What are the components of the classic triad of pre-eclampsia?

The classic triad of pre-eclampsia is characterized by hypertension, edema, and proteinuria. This condition typically occurs after the 20th week of gestation and can pose significant risks to both the mother and fetus if not properly managed.

Hypertension refers to elevated blood pressure, which is a primary feature of pre-eclampsia and is crucial for diagnosis. Edema, or swelling, particularly of the hands and face, can occur due to fluid retention and is common in this condition. Proteinuria, the presence of excess protein in the urine, indicates that the kidneys are affected, which is another hallmark sign of pre-eclampsia.

While the other options include symptoms or conditions that may be observed in various medical scenarios, they do not specifically align with the defining characteristics of pre-eclampsia. Therefore, the response identifying hypertension, edema, and proteinuria as the components of the classic triad accurately captures the critical clinical features of this serious pregnancy complication.
