Past medical history is significant for essential hypertension, managed with lifestyle modifications and 2 antihypertensives for the previous 6 months. Her blood pressure is 15090 mm Hg. Neurological examination is normal. A third antihypertensive drug is added that acts as a selective α2 adrenergic receptor agonist. On follow-up, she reports that she does not have any symptoms and her blood pressure is 12482 mm Hg. Which of the following mechanisms best explains the therapeutic effect of this new drug in this patient?? A: Negative inotropic effect on the heart, B: Vasodilation of peripheral veins, C: Vasodilation of peripheral arteries, D: Decreased peripheral sympathetic outflow, E: Vasodilation of peripheral arteries and peripheral veins,  <response>: This is a question about the mechanism of action of an α2 adrenergic receptor agonist antihypertensive drug in treating a patient with hypertension. The key details in the stem are that the patient has hypertension, is on two other antihypertensives, and adding this new drug improved her blood pressure. α2 agonists work centrally to reduce sympathetic outflow, so the mechanism must relate to reducing peripheral resistance through effects on arteries andor veins.D: Decreased peripheral sympathetic outflow
