A client has been treated for uncontrolled atrial fibrillation with cardioversion. Following the cardioversion, which assessment finding indicates to the nurse that the desired outcome was achieved?
Normal sinus rhythm (NSR) at 84 beats/minute.
Regular rhythm with consistent pacemaker capture.
Return of elevated ST segment to the baseline.
Increased frequency of QRS complexes.
The Correct Answer is A
A. Normal sinus rhythm (NSR) at 84 beats/minute. The goal of cardioversion for atrial fibrillation (AFib) is to restore a normal sinus rhythm (NSR). NSR indicates that the atria and ventricles are depolarizing in a coordinated manner, reducing the risk of thromboembolism, stroke, and hemodynamic instability. A heart rate of 84 beats/minute is within the normal range, confirming the success of the procedure.
B. Regular rhythm with consistent pacemaker capture. Cardioversion is used to restore normal rhythm in AFib, not to manage pacemaker function. A pacemaker is not part of standard AFib cardioversion unless the client has underlying conduction issues requiring pacing.
C. Return of elevated ST segment to the baseline. ST elevation suggests acute myocardial infarction (MI), which is unrelated to atrial fibrillation or cardioversion. Cardioversion does not treat ST elevation or myocardial ischemia, making this an incorrect indicator of success.
D. Increased frequency of QRS complexes. An increase in QRS frequency suggests tachycardia, which would indicate treatment failure rather than success. The goal of cardioversion is to restore a normal, controlled heart rate and rhythm, not to increase the number of ventricular contractions.

Correct Answer is A
Explanation
A. Provide a bedside table for the client to lean across. Clients with acute pancreatitis often experience severe epigastric pain that radiates to the back. Leaning forward helps reduce pressure on the inflamed pancreas and relieves pain by minimizing peritoneal irritation. Providing a bedside table allows the client to rest in a comfortable, supported position, improving pain management without additional interventions.
B. Place bed in the reverse Trendelenburg position. Reverse Trendelenburg elevates the head and lowers the feet, which does not specifically relieve pain associated with pancreatitis. The client instinctively leans forward for relief, and adjusting the bed position would not provide the same benefit. This intervention does not directly address the underlying cause of discomfort.
C. Encourage bed rest until analgesic takes effect. Although pain control is essential, keeping the client in a supine or bedrest position can increase abdominal pressure and worsen discomfort. Allowing the client to assume a comfortable position enhances the effectiveness of analgesics and prevents unnecessary distress. Pain relief strategies should focus on both pharmacologic and positioning interventions.
D. Raise the head of the bed to a 90-degree angle. Elevating the head of the bed can improve breathing and reduce reflux, but it does not provide the same pressure relief as leaning forward. Sitting upright without forward support does not effectively relieve peritoneal irritation from pancreatic inflammation. Providing a bedside table supports proper positioning and enhances comfort.
Correct Answer is A
Explanation
A. Document that the client is experiencing a paced rhythm. A pacemaker spike before each QRS complex indicates that the pacemaker is functioning properly and triggering ventricular depolarization as intended. Since the client is 24 hours postoperative from a pacemaker insertion, this is an expected finding and should be documented accordingly.
B. Reposition the ECG leads and obtain another recording. If the ECG showed artifact, lead displacement, or interference, repositioning the leads might be appropriate. However, the presence of consistent pacemaker spikes before each QRS complex suggests proper pacemaker function rather than a lead issue.
C. Assess the client for symptoms of decreased cardiac output. A paced rhythm is expected after pacemaker insertion and does not necessarily indicate hemodynamic instability. While assessment is always important, there is no indication that the client is experiencing decreased cardiac output symptoms such as hypotension, dizziness, or altered mental status.
D. Notify the healthcare provider (HCP) of the telemetry recording. Routine paced rhythms do not require immediate provider notification unless there are malfunctions such as failure to capture, failure to sense, or failure to pace. Since the pacemaker is functioning appropriately, notifying the HCP is unnecessary.
