A nurse is caring for a patient with mitral stenosis. Based on the pathophysiology of this disease process, the nurse would expect the patient to exhibit which of the following heart rhythms?
A) Normal sinus rhythm
B) Supraventricular tachycardia
C) Atrial fibrillation
D) Electromechanical dissociation
Ans: C
Feedback: A patient with mitral stenosis has a weak and often irregular pulse because of atrial fibrillation (caused by strain on the atrium). A low-pitched, rumbling, diastolic murmur is heard at the apex. The patient experiences atrial dysrhythmias. An echocardiogram is used to diagnose mitral stenosis.
