A 34-year-old previously healthy female was admitted to the hospital in labor. She was hypertensive on admission and complained of right upper quadrant pain. Fifteen minutes after delivery she developed a generalized onset motor seizure and was intubated and admitted to the ICU.

Her seizure is MOST likely:

a. A late initial manifestation of a preexisting epilepsy
b. A complication of delivery before normalization of blood pressure
c. Associated with subcortical vasogenic cerebral edema on imaging
d. A complication of high dermatomal level of epidural analgesia/anesthesia
e. Associated with thrombocytosis and cerebral vascular occlusion

Question 2#Print Question

A 63-year-old man with a history of hypertension controlled with three agents and type 2 diabetes treated with metformin presents with new-onset confusion, nausea, and vomiting. His daughter states that he had self-discontinued his antihypertensive medications. He is normoglycemic but hypertensive with systolic blood pressure consistently above 200 mm Hg.

Brain imaging did not show evidence of acute hemorrhage or ischemic changes; chest imaging was unremarkable. Assuming that the patient’s symptoms are due to hypertension, the recommended goal for blood pressure reduction during the first hour is:

a. <140 mm Hg
b. <160 mm Hg
c. ≤15%
d. ≤25%
e. ≤40%

Which of the following is MOST likely to predict an adverse clinical outcome in this patient?
