A nurse is assisting in the care of a client who has preeclampsia with severe features and is reporting blurred vision and the inability to think clearly.
Which of the following factors should the nurse recognize as the primary cause of the client's clinical manifestations?
Platelet aggregation.
Autoregulation dysfunction of the cerebral vasculature.
Oxidative stress inflammatory response.
Uteroplacental ischemia.
The Correct Answer is B
Choice A rationale
Platelet aggregation is associated with the formation of blood clots, which may contribute to complications like stroke but is not the primary cause of the client's symptoms of blurred vision and cognitive impairment in preeclampsia.
Choice B rationale
Autoregulation dysfunction of the cerebral vasculature causes increased cerebral blood flow and edema, leading to neurological symptoms such as blurred vision and impaired cognitive function. This dysfunction is a primary factor in the pathophysiology of preeclampsia with severe features.
Choice C rationale
Oxidative stress and inflammatory response contribute to endothelial dysfunction in preeclampsia but are not directly responsible for the neurological symptoms described. These factors play a broader role in the progression of the disease.
Choice D rationale
Uteroplacental ischemia affects the placenta and fetal environment, contributing to fetal growth restriction and distress but does not directly cause neurological symptoms like blurred vision in the mother.

Choice C rationale
Three parity is incorrect because the previous pregnancies did not result in three separate viable deliveries.
Choice D rationale
Four parity is incorrect as the client’s history includes one viable delivery (twins) and does not account for four separate viable births. .
