Which physiological response will the nurse expect to assess in patients taking hydralazine (Apresoline), which is a vasodilator medication?

Choice A reason: This is not a physiological response to hydralazine. Cool extremities are a sign of poor peripheral perfusion, which can be caused by vasoconstriction, not vasodilation. Choice B reason: This is not a physiological response to hydralazine. Increased urinary output is a sign of diuresis, which can be caused by diuretic medications, not vasodilators. Choice C reason: This is not a physiological response to hydralazine. Pale skin is a sign of reduced blood flow to the skin, which can be caused by vasoconstriction, not vasodilation. Choice D reason: This is a physiological response to hydralazine. Reflex tachycardia is a compensatory mechanism that occurs when the blood pressure drops due to vasodilation. The heart rate increases to maintain the cardiac output and perfusion pressure.
