The client has been prescribed furosemide 40 mg IV to treat peripheral edema. Which method should the nurse use to best evaluate the client's response to this medication?

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.

Choice A reason: Performing daily weights is the best method to evaluate the client's response to furosemide, a drug that reduces fluid retention and swelling by increasing the urine output. ¹ Daily weights can help monitor the changes in the client's fluid status and the effectiveness of the drug. The nurse should weigh the client at the same time each day, using the same scale and clothing.

Choice B reason: Taking the blood pressure is not the best method to evaluate the client's response to furosemide. Furosemide can also lower the blood pressure by reducing the volume of fluid in the blood vessels. ¹ However, blood pressure can be influenced by many other factors, such as heart rate, stress, or medications. Blood pressure is not a reliable indicator of the client's fluid status or the effectiveness of the drug.

Choice C reason: Auscultating breath sounds is not the best method to evaluate the client's response to furosemide. Furosemide can help improve the breath sounds by reducing the fluid accumulation in the lungs, which can cause shortness of breath or crackles. ¹ However, breath sounds can also be affected by other factors, such as lung infections, asthma, or allergies. Breath sounds are not a reliable indicator of the client's fluid status or the effectiveness of the drug.

Choice D reason: Measuring urinary output is not the best method to evaluate the client's response to furosemide. Furosemide can increase the urinary output by stimulating the kidneys to excrete more water and electrolytes. ¹ However, urinary output can also vary depending on the fluid intake, kidney function, or other medications. Urinary output is not a reliable indicator of the client's fluid status or the effectiveness of the drug.
