Her pregnancy has been otherwise uneventful. The past medical history is unremarkable. The blood pressure is 195150 mm Hg and the pulse is 88min. On examination, moderate pitting edema is present in her ankles. The urinalysis is normal except for 3 proteinuria. The obstetrician orders a complete blood count CBC, liver function tests LFTs, creatinine, and a coagulation profile. The obstetrician transfers her to the hospital by ambulance for expectant management. Which of the following medications would be most helpful for this patient?? A: Hydrochlorothiazide, B: Lisinopril, C: Metoprolol, D: Olmesartan, E: Nifedipine,  <response>: This is a question about the appropriate medication treatment for a pregnant patient presenting with severe preeclampsia. The key findings in the stem are the 28-week gestation, severe headache, blurred vision, vomiting, very elevated blood pressure of 195150 mmHg, pitting edema, and 3 proteinuria on urinalysis. These findings are consistent with severe preeclampsia. The goal of treatment is to control the severely elevated blood pressure to prevent complications like stroke, seizure, placental abruption, and adverse effects on the fetus. Of the medication choices provided, nifedipine is a calcium channel blocker that can rapidly lower blood pressure and is considered first-line for treating severe hypertension in pregnancy. Hydrochlorothiazide is a diuretic and would not be first-line. Lisinopril is an ACE inhibitor contraindicated in pregnancy. Metoprolol is a beta blocker that may worsen placental perfusion. Olmesartan is an angiotensin receptor blocker also contraindicated in pregnancy.E: Nifedipine
