[{'content': 'A 32-year-old primigravida at 39 weeks of gestational age has a blood pressure reading of 150/100 mm Hg obtained during a routine visit. Her baseline blood pressure during the pregnancy was 120/70 mmHg. The patient denies any headache, visual changes, nausea, vomiting, or abdominal pain. Her repeat BP is 160/90 mmHg, and urinalysis is negative for protein. Which of the following is the most likely diagnosis? \nSelect and explain. \nA. Preeclampsia, B. Chronic hypertension with superimposed preeclampsia, C. Eclampsia, D. Gestational hypertension', 'role': 'user'}, {'content': "Answer: D \nExplanation: Ans. is 'd' i.e., Gestational hypertension * Hypertension in pregnancy is defined as blood pressure of 140/90 mmHg or greater on at least two separate occasions that are 6 h or more apart. The presence of edema is no longer used as a diagnostic criterion because it is so prevalent in normal pregnant women. A rise in systolic blood pressure of 30 mmHg and a rise in diastolic blood pressure of 15 mmHg are also no longer used.* In gestational hypertension, maternal blood pressure reaches 140/90 or greater for the first time during pregnancy, and proteinuria is not present. In preeclampsia, blood pressure increases to 140/90 after 20 weeks of gestation and proteinuria is present (300 mg in 24 h or 1+ protein or greater on dipstick). Eclampsia is present when women with preeclampsia develop seizures.* Chronic hypertension is defined as BP >140/90 mmHg before pregnancy or diagnosed before 20 weeks of gestation, or hypertension first diagnosed after 20 weeks of gestation and persistent after 12 weeks postpartum.* A woman with hypertension who develops preeclampsia is described as having chronic hypertension with superimposed preeclampsia.", 'role': 'assistant'}]
