Which monitoring parameter is most important for early detection of progression from preeclampsia to severe disease requiring urgent delivery?

• A. Monthly maternal height measurements since changes in stature predict progression to eclampsia.
• B. Trends of blood pressure, new or worsening proteinuria, and signs of end-organ dysfunction such as rising liver enzymes, low platelets, or worsening renal function.
• C. Reliance solely on fetal movement counts without maternal clinical assessment, because maternal disease does not progress without fetal symptoms.
• D. Only home urine color observation is required because a darker urine always precedes organ failure.

Answer: (B)
