Final answer:
Abnormal laboratory values in preeclampsia may include thrombocytopenia, the presence of burr cells, and elevated BUN. A low hemoglobin level and elevated LDH may also be present but should be evaluated in context.
Step-by-step explanation:
Patients diagnosed with preeclampsia commonly exhibit certain abnormal laboratory values. The laboratory values that may be found in a patient with preeclampsia include a low hemoglobin level, thrombocytopenia (low platelet count), elevated levels of liver enzymes such as lactate dehydrogenase (LDH), the presence of burr cells (echinocytes) on a peripheral blood smear, and a possible increase in blood urea nitrogen (BUN). Specifically, options B (Platelet count of 75,000), D (Burr cells), and E (BUN 25 mg/dL) could be associated with preeclampsia. A hemoglobin level of 8 g/dL (option A) could reflect the hemolysis that occurs in severe cases, and LDH 100 units/L (option C) seems to be within the normal range and might not be indicative of preeclampsia without additional context.
