A nurse is caring for a client following a synchronized cardioversion. Which of the following findings indicates a therapeutic response to the treatment?

Rationale: A. Weak peripheral pulses on palpation: Weak peripheral pulses can indicate poor circulation or low cardiac output, which is not a therapeutic response to synchronized cardioversion. The goal is to restore a normal rhythm and improve perfusion. B. Cardiac monitor indicates sinus rhythm: Sinus rhythm on the cardiac monitor indicates that the cardioversion was successful in restoring a normal heart rhythm, making this the therapeutic response. This is the desired outcome after synchronized cardioversion. C. Diminished breath sounds on auscultation: Diminished breath sounds are more indicative of respiratory issues, such as fluid in the lungs or atelectasis, and are not related to the effectiveness of synchronized cardioversion. D. Pacer spikes precede the QRS complex on the ECG tracing: Pacer spikes are seen in patients with a pacemaker, not typically following synchronized cardioversion. If pacer spikes are seen, it indicates that pacing is occurring, which may be necessary in some situations, but it is not a sign of the success of cardioversion.
