Final answer:
The pregnant patient with preeclampsia has secondary hypertension, which is caused by an underlying condition, in this case, pregnancy.
Step-by-step explanation:
The patient is in her 8th month of pregnancy with a blood pressure of 210/100 mm Hg and diagnosed with preeclampsia has secondary hypertension. Secondary hypertension is a type of high blood pressure that results from a specific underlying condition, unlike primary hypertension, which has no identifiable cause and is more common. In the case of preeclampsia, the hypertension is directly related to the pregnancy and is therefore classified as secondary. Management of this condition is critical, as untreated hypertension can lead to serious health complications like heart disease, stroke, and complications in pregnancy.
