Which nursing assessment confirms that the angiotensin II receptor blocker (ARB) that a patient is taking is effective?
LDL cholesterol levels have decreased
Weight loss of more than 2 pounds/week
Urinary output is increased
Blood pressure has decreased
The Correct Answer is D
Choice A reason: ARBs do not affect the LDL cholesterol levels. They lower the blood pressure by blocking the action of angiotensin II, which is a hormone that causes vasoconstriction and sodium retention. Statins are the drugs that lower the LDL cholesterol levels.
Choice B reason: ARBs do not cause weight loss of more than 2 pounds/week. They lower the blood pressure by blocking the action of angiotensin II, which is a hormone that causes vasoconstriction and sodium retention. Diuretics are the drugs that cause weight loss by increasing the urine output and reducing the fluid volume.
Choice C reason: ARBs do not increase the urinary output. They lower the blood pressure by blocking the action of angiotensin II, which is a hormone that causes vasoconstriction and sodium retention. Diuretics are the drugs that increase the urinary output by inhibiting the reabsorption of sodium and water in the kidneys.
Choice D reason: ARBs lower the blood pressure by blocking the action of angiotensin II, which is a hormone that causes vasoconstriction and sodium retention. Therefore, a nursing assessment that confirms that the ARB that a patient is taking is effective is a decrease in the blood pressure. This is the correct statement that describes the expected outcome of ARBs.

Correct Answer is A
Explanation
Choice A reason: This is the correct mechanism of action of propranolol. Propranolol is a beta blocker medication, which means that it blocks the beta receptors in the heart and blood vessels. This reduces the sympathetic stimulation in cardiac muscle, which lowers the heart rate, contractility, and oxygen demand. This also reduces the renin release from the kidneys, which lowers the blood pressure.
Choice B reason: This is not the mechanism of action of propranolol. Propranolol does not increase the diuretic response in the renal tubules. This is the effect of diuretic medications, such as furosemide or hydrochlorothiazide, which increase the urine output and decrease the blood volume and pressure.
Choice C reason: This is not the mechanism of action of propranolol. Propranolol does not inhibit the conversion of angiotensin I to angiotensin II. This is the effect of angiotensin-converting enzyme (ACE) inhibitors, such as lisinopril or enalapril, which block the formation of angiotensin II, a potent vasoconstrictor that raises the blood pressure.
Choice D reason: This is not the mechanism of action of propranolol. Propranolol does not block alpha receptors throughout the body. This is the effect of alpha blockers, such as doxazosin or prazosin, which block the alpha receptors in the blood vessels and cause vasodilation, which lowers the blood pressure.
Correct Answer is D
Explanation
Choice A reason: Abnormally dilated arteries and veins are not a result of atherosclerosis. They are a sign of aneurysms or varicose veins, which are caused by different factors.
Choice B reason: Arterial wall thinning and weakening are not a result of atherosclerosis. They are a sign of arteriosclerosis, which is a general term for the loss of elasticity and flexibility of the arteries.
Choice C reason: Autonomic nervous system imbalances are not a result of atherosclerosis. They are a sign of dysautonomia, which is a disorder of the nervous system that affects the regulation of vital functions.
Choice D reason: Abnormal thickening and hardening of vessel walls are a result of atherosclerosis. They are caused by the accumulation of plaque, which is composed of cholesterol, fatty substances, calcium, and other materials.
