Final answer:
The nurse should remain alert for ventricular tachycardia as the dysrhythmia associated with frequent premature ventricular contractions (PVCs) in a client admitted for myocardial infarction.
Step-by-step explanation:
The nurse should remain alert for ventricular tachycardia as the dysrhythmia associated with frequent premature ventricular contractions (PVCs) in a client admitted for myocardial infarction. Ventricular tachycardia is a potentially life-threatening arrhythmia characterized by three or more consecutive PVCs at a rate greater than 100 beats per minute.
In ventricular tachycardia, the electrical signals in the heart are originating from the ventricles instead of the normal pacemaker cells. This can cause the heart to beat rapidly and disrupt its normal rhythm.
It is important for the nurse to monitor the client closely for any signs of worsening symptoms or hemodynamic instability, as ventricular tachycardia can lead to a more serious condition such as ventricular fibrillation.
