In a client diagnosed with mitral regurgitation, which symptom should the nurse expect to find in the documentation?

• A. Ascites
• B. Low red blood cell count
• C. Exertional dyspnea
• D. Pulse deficit

Answer: (C)

In a client diagnosed with mitral regurgitation, exertional dyspnea is a common symptom that can be expected. Mitral regurgitation occurs when the mitral valve fails to close properly, leading to backflow of blood from the left ventricle into the left atrium during systole. This backflow can contribute to increased pressure in the pulmonary circulation, resulting in pulmonary congestion. As a result, clients with mitral regurgitation often experience difficulty breathing during physical activities, which is termed exertional dyspnea. This symptom arises because the heart has to work harder to pump blood efficiently, and when the oxygen demand increases during exertion, the compromised function of the heart can lead to insufficient oxygenation, triggering feelings of breathlessness. While the other symptoms listed may be associated with different conditions, in the context of mitral regurgitation specifically, exertional dyspnea stands out as a direct manifestation of the hemodynamic changes caused by the regurgitant flow and its impact on pulmonary circulation.
