The nurse auscultates a heart murmur on a client with cardiovascular disease. At which anatomic landmark will an aortic murmur be heard the loudest?

Second intercostal space, right of sternum.

Third intercostal space, left of sternum.

Second intercostal space, left of sternum.

Fourth intercostal space, left mid-clavicular line.

Answer and Explanation

The Correct Answer is C

Choice A reason: The second intercostal space, right of sternum, is not the anatomic landmark where an aortic murmur will be heard the loudest. A heart murmur is an abnormal sound that is produced by turbulent blood flow through the heart valves or chambers. ¹ An aortic murmur is a type of heart murmur that occurs when the aortic valve, which separates the left ventricle and the aorta, is damaged or diseased. ² The second intercostal space, right of sternum, is the location where the aortic valve can be best heard, but not the location where the aortic murmur will be most audible. ³

Choice B reason: The third intercostal space, left of sternum, is not the anatomic landmark where an aortic murmur will be heard the loudest. A heart murmur is an abnormal sound that is produced by turbulent blood flow through the heart valves or chambers. ¹ An aortic murmur is a type of heart murmur that occurs when the aortic valve, which separates the left ventricle and the aorta, is damaged or diseased. ² The third intercostal space, left of sternum, is the location where the pulmonary valve, which separates the right ventricle and the pulmonary artery, can be best heard, but not the location where the aortic murmur will be most audible. ³

Choice C reason: The second intercostal space, left of sternum, is the anatomic landmark where an aortic murmur will be heard the loudest. A heart murmur is an abnormal sound that is produced by turbulent blood flow through the heart valves or chambers. ¹ An aortic murmur is a type of heart murmur that occurs when the aortic valve, which separates the left ventricle and the aorta, is damaged or diseased. ² The second intercostal space, left of sternum, is the location where the aortic murmur will be most audible, as it is the closest to the aorta, the largest artery in the body. ³

Choice D reason: The fourth intercostal space, left mid-clavicular line, is not the anatomic landmark where an aortic murmur will be heard the loudest. A heart murmur is an abnormal sound that is produced by turbulent blood flow through the heart valves or chambers. ¹ An aortic murmur is a type of heart murmur that occurs when the aortic valve, which separates the left ventricle and the aorta, is damaged or diseased. ² The fourth intercostal space, left mid-clavicular line, is the location where the tricuspid valve, which separates the right atrium and the right ventricle, can be best heard, but not the location where the aortic murmur will be most audible. ³

Correct Answer is A

Explanation

Choice A reason: This is the correct answer. Tremors and twitching are signs of hypomagnesemia, which is a low level of magnesium in the blood. Magnesium is a mineral that is involved in many enzymatic reactions and neuromuscular functions. A low magnesium level can cause hyperexcitability of the nerves and muscles, leading to involuntary movements and spasms. Alcoholism can cause hypomagnesemia by reducing the absorption and increasing the excretion of magnesium.

Choice B reason: Positive Chvostek's sign is not a sign of hypomagnesemia, but of hypocalcemia, which is a low level of calcium in the blood. Calcium is another mineral that is important for the function of nerves and muscles. A low calcium level can cause tetany, which is a condition of sustained muscle contraction. Chvostek's sign is a test that involves tapping the facial nerve in front of the ear and observing for a twitching of the facial muscles. A positive Chvostek's sign indicates hypocalcemia, not hypomagnesemia.

Choice C reason: Decreased deep tendon reflexes are not a sign of hypomagnesemia, but of hypermagnesemia, which is a high level of magnesium in the blood. A high magnesium level can cause hyporeflexia, which is a reduced or absent response to stimuli. Magnesium has a sedative effect on the nerves and muscles, and can inhibit the transmission of impulses. Hypermagnesemia can be caused by excessive intake or impaired excretion of magnesium.

Choice D reason: Polyuria and flank pain are not signs of hypomagnesemia, but of kidney problems, such as infection, stones, or failure. Polyuria is the production of abnormally large amounts of urine, and flank pain is the pain in the side or back below the ribs. These symptoms can indicate damage or inflammation of the kidneys, which can affect the balance of fluids and electrolytes in the body. Hypomagnesemia does not directly cause polyuria or flank pain, but it can be a result of kidney dysfunction.

A. Have analgesic properties without sedation B. Can trigger vasodilation and improve blood flow C. Improve contractility and decrease afterload D. Inhibit platelet aggregation and clot formation

Correct Answer is A

Explanation

Choice A reason: Having analgesic properties without sedation is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel are antiplatelet drugs that prevent blood clots from forming in the arteries that supply the heart. They do not have significant analgesic or sedative effects.

Choice B reason: Triggering vasodilation and improving blood flow is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel do not directly cause vasodilation or increase blood flow. They work by reducing the stickiness of platelets and preventing them from clumping together and blocking the arteries.

Choice C reason: Improving contractility and decreasing afterload is not the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel do not affect the contractility or the afterload of the heart. They act on the blood vessels and the blood cells, not on the heart muscle. Contractility and afterload are influenced by other drugs such as beta-blockers, calcium channel blockers, and angiotensin-converting enzyme inhibitors.

Choice D reason: This is the correct answer. Inhibiting platelet aggregation and clot formation is the rationale for prescribing aspirin and clopidogrel for coronary artery disease. Aspirin and clopidogrel are antiplatelet drugs that interfere with the function of platelets, which are blood cells that help with clotting. By inhibiting platelet aggregation and clot formation, aspirin and clopidogrel reduce the risk of heart attack and stroke in people with coronary artery disease.
