A nurse in a clinic is caring for an adolescent client who is at 24 weeks of gestation and showing signs of preeclampsia. Which of the following findings should the nurse expect?

A. Decreased BUN is not expected in preeclampsia. Instead, renal impairment can cause BUN and creatinine to increase due to decreased kidney perfusion. B. Serum uric acid typically increases in preeclampsia as a result of reduced renal clearance; a decreased value would not be expected. C. Increased protein in urine (proteinuria) is a hallmark sign of preeclampsia, reflecting glomerular damage and impaired renal function. It is used diagnostically in conjunction with elevated blood pressure and edema. D. Increased platelet count is incorrect because preeclampsia often causes thrombocytopenia due to platelet aggregation and consumption within damaged vessels.
