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.
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 C
Explanation
Choice A reason: Stopping the medication if the client develops a change in vision is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Change in vision is not a common or serious side effect of rosuvastatin, and it may be caused by other factors, such as eye strain, infection, or disease. The nurse should not advise the client to stop the medication without consulting the healthcare provider, as this may increase the risk of adverse outcomes, such as heart attack or stroke.
Choice B reason: Monitoring body weight weekly is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Body weight is not a direct indicator of the effectiveness or safety of rosuvastatin, and it may fluctuate due to various factors, such as diet, exercise, or fluid retention. The nurse should encourage the client to maintain a healthy weight and lifestyle, but not to focus on the weekly changes in body weight.
Choice C reason: Reporting muscle weakness or pain is the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. However, statins can also cause muscle damage, which can manifest as weakness, pain, tenderness, or cramps. This can be a sign of a serious condition called rhabdomyolysis, which is the breakdown of muscle tissue that can lead to kidney failure or death. The nurse should instruct the client to report any muscle symptoms to the healthcare provider as soon as possible, and to avoid taking any other drugs or supplements that may interact with rosuvastatin and increase the risk of muscle damage.
Choice D reason: Having biannual renal function studies is not the information that the nurse should provide in the teaching about rosuvastatin. Rosuvastatin is a drug that lowers the cholesterol and prevents the complications of cardiovascular disease. It belongs to a class of drugs called statins, which work by inhibiting an enzyme that produces cholesterol in the liver. Renal function studies are tests that measure the health and function of the kidneys, which are responsible for filtering the blood and removing waste and excess fluid. Rosuvastatin is not known to cause significant kidney damage, and it is excreted mainly by the liver. The nurse should not recommend the client to have biannual renal function studies, as this may be unnecessary and costly. The nurse should advise the client to follow the healthcare provider's orders regarding the frequency and type of laboratory tests that are needed to monitor the effects of rosuvastatin.
Correct Answer is D
Explanation
Choice A reason: Taking a baby aspirin with a full glass of cold water at bedtime is not a good discharge instruction for this client. Aspirin can increase the risk of bleeding, especially in the stomach and intestines. ¹ Taking aspirin at bedtime may increase the exposure of the GI mucosa to the drug and worsen the bleeding. ² Cold water may also irritate the stomach lining and cause discomfort.
Choice B reason: Taking 81 mg of enteric coated aspirin with orange juice at lunch time is not a good discharge instruction for this client. Enteric coated aspirin is designed to dissolve in the small intestine, not the stomach, to reduce the risk of GI bleeding. ³ However, orange juice is acidic and may damage the coating and release the aspirin in the stomach. ⁴ This may increase the bleeding and cause pain or ulcers.
Choice C reason: Taking the aspirin with some ginseng tea in the evening is not a good discharge instruction for this client. Ginseng is an herbal supplement that may interact with aspirin and increase the risk of bleeding. ⁵ Taking the aspirin in the evening may also have the same drawbacks as taking it at bedtime, as explained in choice A.
Choice D reason: Taking the aspirin with a glass of milk or food in the morning is the best discharge instruction for this client. Milk and food can help protect the stomach lining from the irritating effects of aspirin and reduce the risk of bleeding. Taking the aspirin in the morning can also minimize the exposure of the GI mucosa to the drug during the night, when the stomach is empty and more vulnerable. ²
