Question 1 of 5
A 55-year-old woman with a long history of poorly controlled essential hypertension had recently added atenolol to her therapeutic regimen. Which of the following was most likely a primary mechanism that mediated the antihypertensive effect of atenolol in this patient?
Correct Answer: C
Rationale: The correct answer is C: Blockade of beta receptors of the vascular wall. Atenolol is a beta-blocker that works by blocking beta receptors in the vascular wall, leading to reduced sympathetic stimulation and vasodilation, ultimately lowering blood pressure. Choice A is incorrect as atenolol primarily affects beta receptors, not large veins. Choice B is incorrect as atenolol does not directly affect epinephrine release from the adrenal medulla. Choice D is incorrect as atenolol primarily acts at the beta receptors in the vascular wall rather than affecting sympathetic outflow from the vasomotor area.
