CONCEPT MAP WORKSHEET DESCRIBE DISEASE PROCESS AFFECTING PATIENT (INCLUDE PATHOPHYSIOLOGY OF DISEASE PROCESS) “Preeclampsia is the result of generalized vasospasms. The underlying cause of vasospasm remains a mystery, but some of the physiologic processes are known. In a normal pregnancy, vascular volume is significantly increased, and cardiac output is increased. Despite these factors, blood pressure does not rise in a normal pregnancy, probably because pregnant women develop resistance to the effects of vasoconstrictors such as angiotensin II. Moreover, a decrease in peripheral vascular resistance occurs from the effects of certain vasodilators, such as prostacyclin (PGI2), prostaglandin E2 (PGE2), and endothelium-derived relaxing factor (EDRF). In preeclampsia, however, peripheral vascular resistance increases because of the sensitivity of some women to angiotensin II and a decrease in vasodilators. For example, the ratio of thromboxane A2 to PGI2 increases. Thromboxane, produced by kidney and trophoblastic tissue, causes vasoconstriction and platelet aggregation (clumping)/ PGI2, produced by placental tissue and endothelial cells causes vasodilation and inhibits platelet aggregation.” (McKinney, James, Murray, Nelson, & Ashwill, 2018) “Severe preeclampsia consists of blood pressure that is 160/110 mm Hg or greater, proteinuria greater than 3+, oliguria, elevated blood creatinine greater than 1.1 mg/dL, cerebral or visual disturbances (headache and blurred vision, hyperreflexia with possible ankle clonus, pulmonary or cardiac involvement, extensive peripheral edema, hepatic dysfunction, epigastric and right upper-quadrant pain, and thrombocytopenia.” (Holman et al., 2019)
