A 39-year-old pregnant woman in labor with preeclampsia develops chest tenderness and right upper quadrant pain, as well as pain when breathing deeply. Her lab results are as follows: hemoglobin 7.8 g/dL; aspartate aminotransferase 313 U/L; alanine aminotransferase 225 U/L; platelets 85,000/mcL. Which of the following most closely aligns with this clinical scenario?

Choice A reason: HELLP syndrome is a severe form of preeclampsia characterized by Hemolysis, Elevated Liver enzymes, and Low Platelets. The patient’s lab values and clinical symptoms of right upper quadrant pain and chest tenderness are classic indicators of HELLP. Choice B reason: Gestational diabetes involves hyperglycemia during pregnancy and does not typically present with liver enzyme elevations, hemolysis, or low platelets. Choice C reason: Toxoplasmosis is an infectious condition that can affect the fetus but does not produce the constellation of maternal lab abnormalities seen here. Choice D reason: Cytomegalovirus infection can cause systemic symptoms, but it does not explain the combination of preeclampsia, elevated liver enzymes, low platelets, and hemolysis.
