A nurse is assisting in the care of a client at 30 weeks of gestation who has a blood pressure reading of 160/116 mm Hg and 4 hours previously it was 164/114 mm Hg. The client reports blurred vision and a persistent frontal headache.
Which of the following complications of gestation should the nurse suspect?
Gestational hypertension.
Preeclampsia with severe features.
Preeclampsia without severe features.
Chronic hypertension.
The Correct Answer is B
Choice A rationale
Gestational hypertension is diagnosed when high blood pressure develops after 20 weeks of pregnancy without other symptoms of preeclampsia, such as proteinuria or end-organ dysfunction.
Choice B rationale
Preeclampsia with severe features includes high blood pressure, proteinuria, and symptoms like blurred vision and headaches. These indicate severe disease, which can endanger both the mother and the fetus if left untreated.
Choice C rationale
Preeclampsia without severe features involves high blood pressure and proteinuria but without the additional severe symptoms like blurred vision and headache.
Choice D rationale
Chronic hypertension refers to high blood pressure that was present before pregnancy or diagnosed before 20 weeks of gestation. It does not typically present with acute symptoms like blurred vision and headache that develop suddenly.

Correct Answer is B
Explanation
Choice A rationale
Hyperthyroidism is more likely to occur in women of childbearing age and does not have a higher incidence post-menopause. It is often associated with autoimmune disorders such as Graves' disease, which can affect individuals at any age.
Choice B rationale
Graves' disease is an autoimmune disorder that is a common cause of hyperthyroidism. It results from the immune system producing antibodies that stimulate the thyroid gland to produce excessive thyroid hormones.
Choice C rationale
Cardiovascular disease is not a direct cause of hyperthyroidism. However, untreated hyperthyroidism can lead to complications such as atrial fibrillation and heart failure due to the overproduction of thyroid hormones.
Choice D rationale
Hyperthyroidism results in excessive production of thyroid hormones, not too little. This excess leads to symptoms such as weight loss, heat intolerance, tremors, and increased metabolism, distinguishing it from hypothyroidism.
Correct Answer is B
Explanation
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.
