The nurse auscultates a systolic murmur in the second intercostal space to the right of the sternum while performing a cardiac assessment on a client. The nurse interprets this finding as:

Choice A reason: A history of cardiac disease is not directly related to enlarged axillary lymph nodes. Cardiac disease may affect the heart, blood vessels, and circulation, but not the lymphatic system. ¹

Choice B reason: A recent infection is a possible cause of enlarged axillary lymph nodes. Lymph nodes are part of the immune system and they swell when they are fighting an infection. ² The nurse should ask the client about any signs or symptoms of infection, such as fever, sore throat, or skin rash.

Choice C reason: Shortness of breath is not directly related to enlarged axillary lymph nodes. Shortness of breath may indicate a respiratory problem, such as asthma, bronchitis, or pneumonia. ³ However, these conditions do not usually affect the lymph nodes in the armpit area.

Choice D reason: Surgery on the neck is not directly related to enlarged axillary lymph nodes. Surgery on the neck may affect the lymph nodes in the neck or the collarbone area, but not the lymph nodes in the armpit area. The nurse should ask the client about any history of surgery or trauma to the lymph nodes or the surrounding tissues.

Choice A reason: This is not a correct interpretation. An occlusion of the right coronary artery is a blockage of the blood flow to the right side of the heart, which can cause a heart attack or ischemia. This condition does not produce a systolic murmur, but rather chest pain, shortness of breath, sweating, or nausea. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.

Choice B reason: This is not a correct interpretation. An aneurysm of the descending aorta is a bulging or weakening of the wall of the large artery that carries blood from the heart to the lower body. This condition does not produce a systolic murmur, but rather a pulsating mass in the abdomen, back pain, or abdominal pain. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.

Choice C reason: This is not a correct interpretation. Decreased fluid in the pericardial sac is a condition where the amount of fluid that surrounds and cushions the heart is reduced. This can be caused by dehydration, infection, or inflammation. This condition does not produce a systolic murmur, but rather a pericardial friction rub, which is a scratching or grating sound that occurs when the layers of the pericardium rub against each other. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.

Choice D reason: This is the correct interpretation. Distortion of one or more heart valves is a condition where the shape or function of the valves that regulate the blood flow through the heart is altered. This can be caused by congenital defects, rheumatic fever, endocarditis, or aging. This condition can produce a systolic murmur, which is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve. The location and the intensity of the murmur can help identify which valve is affected. A systolic murmur in the second intercostal space to the right of the sternum can indicate a problem with the aortic valve.
