A client who is 1 day postpartum receives a varicella vaccine in the hospital.
Which of the following responses indicates that the client will need further teaching about the vaccine?

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 A rationale

An increase in serum bilirubin levels indicates worsening hyperbilirubinemia rather than improvement. Effective phototherapy should result in a decrease in bilirubin levels as it helps break down bilirubin into a form that can be excreted.

Choice B rationale

Hemoglobin and hematocrit levels are not directly affected by phototherapy. These values are more related to red blood cell count and do not indicate the effectiveness of phototherapy for treating hyperbilirubinemia.

Choice C rationale

A decrease in transcutaneous bilirubin (TcB) levels from 6 hours ago indicates effective phototherapy. Phototherapy reduces bilirubin levels in the blood by converting it to a water-soluble form that can be eliminated from the body.

Choice D rationale

Jaundice typically moves from the head to the lower body as bilirubin levels decrease. Movement from chest to groin level without a corresponding decrease in bilirubin levels does not necessarily indicate effective phototherapy. .
