Vasoconstriction
π· Vasoconstriction is correct because preeclampsia involves widespread endothelial dysfunction that leads to increased vascular tone and narrowing of blood vessels.
π· This abnormal vasoconstriction decreases organ perfusion and contributes to platelet activation and coagulation changes.
π· As the disease progresses, clotting factors and platelets can be consumed in the damaged vascular system.
π· This helps explain why coagulation-related laboratory values may gradually worsen during pregnancy.
π· Because vasoconstriction is a central pathophysiologic feature of preeclampsia, it is responsible for the abnormal laboratory trend.
Vasospasms
π· Vasospasms are correct because preeclampsia is classically associated with widespread vasospasm and reduced perfusion to maternal organs and the placenta.
π· Vasospasm causes tissue hypoxia and endothelial injury, which promote platelet consumption and coagulation abnormalities.
π· These vascular changes are part of why preeclampsia is considered a multisystem disorder.
π· Persistent vasospasm can progressively worsen maternal laboratory values even before severe complications appear.
π· Therefore, vasospasms are an important cause of the clientβs current clotting-factor changes.
Client end-organ damage
π· Client end-organ damage is correct because preeclampsia affects organs such as the kidneys, liver, brain, and hematologic system through abnormal vascular injury and reduced perfusion.
π· End-organ involvement contributes to laboratory abnormalities, including thrombocytopenia and deranged coagulation in worsening disease.
π· Even without severe features, the disease process is still based on multisystem endothelial injury.
π· The slow change in clotting-related labs reflects the underlying systemic pathophysiology rather than a normal pregnancy adaptation.
π· For that reason, end-organ damage is appropriately associated with the clientβs abnormal values.
Proteinuria
π· Proteinuria is a manifestation of renal involvement in preeclampsia, not the underlying pathophysiologic cause of decreasing clotting factors.
π· It reflects glomerular injury rather than being the process that drives the coagulation abnormalities.
Cardiac dysfunction
π· Cardiac dysfunction is not the primary pathophysiologic response used to explain the typical clotting-factor decline in preeclampsia.
π· The major mechanism is widespread endothelial injury with vasoconstriction and vasospasm.
Pulmonary edema
π· Pulmonary edema is a serious complication or severe feature of preeclampsia, not the main mechanism causing gradual clotting-factor changes.
π· It reflects disease severity rather than the underlying vascular cause of the abnormal labs.
