The client with suspected mitral valve prolapse asks the nurse about tests that will be done to confirm the diagnosis. Which is the best response by the nurse?
A) "A halter monitor will be used to confirm diagnosis."
B) "An echocardiogram along with clinical symptoms will assist in diagnosis."
C) "A chest x-ray will reveal a prolapse if present."
D) "An ECG that presents a notched P wave will assist with diagnosis."
B
Feedback:
The echocardiogram shows abnormal movement of mitral valve leaflets during systole and can assist in the diagnosis of mitral valve prolapse when used along with clinical symptoms. A notch in the P wave on ECG shows that the left atrium takes longer to depolarize and can assist in the diagnosis of mitral stenosis. A 24-hour ECG via halter monitor is used essentially to eliminate an MI and other causes of chest pain. A chest x-ray can be used to visualize the size and location of the heart but not as significant as echocardiogram.
