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.

Correct Answer is B
Explanation
Choice A rationale
Whitish vaginal discharge is not typically associated with a hydatidiform mole. Instead, it can be a normal finding or related to other conditions.
Choice B rationale
Excessive uterine enlargement is a common sign of a hydatidiform mole, as the abnormal growths cause the uterus to expand more than expected for the gestational age.
Choice C rationale
Rapidly dropping hCG levels are not associated with a hydatidiform mole. In fact, hCG levels are typically abnormally high in cases of a hydatidiform mole due to the overproduction of hCG by the trophoblastic tissue.
Choice D rationale
Fetal heart rate irregularities are not applicable in the case of a complete hydatidiform mole, as there is no viable fetus present.
Correct Answer is A
Explanation
Choice A rationale
Rhythmic respirations indicate the client is using controlled breathing techniques to manage labor pain, which demonstrates effective coping. This method helps maintain oxygen levels and can reduce the perception of pain through focused breathing.
Choice B rationale
Crying during labor may indicate emotional distress or pain, suggesting the client might be struggling to cope effectively with labor. While it is a natural response, it is not typically associated with controlled coping mechanisms.
Choice C rationale
Lack of concentration can indicate that the client is overwhelmed by pain or anxiety, which may hinder her ability to use coping strategies effectively. It suggests she might be struggling to manage her labor experience.
Choice D rationale
Perspiration is a common physiological response to the exertion and stress of labor, but it does not specifically indicate how well the client is coping with labor pain or stress. It is a normal part of the labor process but not a clear sign of effective coping.
