Final answer:
Mild preeclampsia is diagnosed with high blood pressure and protein presence in urine after 20 weeks of pregnancy. It requires monitoring for signs of progression to provide adequate treatment and prevent complications.
Step-by-step explanation:
The requirement for diagnosing mild preeclampsia includes a combination of high blood pressure and the presence of protein in urine after 20 weeks of pregnancy. In particular, a blood pressure that is greater than or equal to 140/90 mmHg on two occasions, at least 4 hours apart, and proteinuria of 300 mg or more in a 24-hour urine sample, or a protein/creatinine ratio of at least 0.3, or a dipstick reading of 1+ (on at least two random urine samples collected at least 4 to 6 hours apart with no exercise in between).
It's important to monitor the case for any signs of worsening to prevent potential complications for both the mother and the fetus. Because it can progress to severe preeclampsia, close observation and management are critical. Treatment focuses on managing symptoms and includes close monitoring of both the mother and baby, possible bed rest, and sometimes medications.
