Gastrointestinal System Quiz Questions Questions
Question 1 of 5
A 28-year-old woman at 34 weeks of gestation presents with elevated liver enzymes and pruritus. Labs reveal total bilirubin to be 4.2 mg/dL, AST 480 U/L, ALT 640 U/L, and alkaline phosphatase 232 U/L. Viral hepatitis serologies and ANA are negative. On physical examination, she is jaundiced, but has a normal blood pressure, no edema, and a soft abdomen. The fetus is in no distress. Which of the following is true?
Correct Answer: B
Rationale: The likely diagnosis is intrahepatic cholestasis of pregnancy, which resolves after delivery. Prompt delivery is indicated only for fetal distress. Intrahepatic cholestasis tends to recur with subsequent pregnancies and can be treated with cholestyramine and ursodeoxycholic acid. LCHAD deficiency is associated with acute fatty liver of pregnancy and HELLP syndrome.
