An older adult male client is admitted after three reported syncopal episodes at home. He has several bruises at various stages of healing noted over his arms and legs. The cardiac monitor shows atrial fibrillation (A-fib) with a ventricular response of 140 beats/minute. In addition to contacting the client's healthcare provider (HCP), which intervention should the nurse implement?

A. Contact the client's healthcare power of attorney: This is appropriate if the client is unable to make decisions or if end-of-life care planning is being addressed. However, the client is alert enough to report syncopal episodes, and the priority is stabilizing his condition. B. Call for immediate help from the rapid response team (RRT): The rapid response team is called for acute, life-threatening changes in clinical. Although the client is tachycardic, there is no indication of immediate decompensation requiring emergency intervention. C. Report the client’s falls and bruises to adult protective services: The presence of bruises alone is not sufficient to trigger a report without further assessment. These bruises may be related to the syncopal events. The nurse must first assess and stabilize the client. D. Monitor the client’s blood pressure and oxygen saturation: With atrial fibrillation and a rapid ventricular response, the client is at risk for hemodynamic instability. Monitoring vital signs helps determine whether the high heart rate is compromising perfusion or oxygenation, guiding the urgency of treatment and further evaluation.
