A nurse is monitoring a client's heart rhythm following insertion of a permanent pacemaker. Which of the following images should the nurse expect?

A
B
C
D
The Correct Answer is D
A: This tracing shows occasional premature ventricular contractions (PVCs) with normal QRS complexes, which is not characteristic of a paced rhythm. A permanent pacemaker typically produces consistent pacing spikes preceding the QRS complex.
B: This tracing demonstrates a very rapid, wide-complex rhythm consistent with ventricular tachycardia, not a normal paced rhythm. This is a potentially life-threatening arrhythmia requiring immediate intervention.
C: This tracing shows an irregular rhythm with abnormal QRS morphology, likely atrial fibrillation with conduction abnormalities. It does not show consistent pacemaker spikes before each QRS complex.
D: This tracing displays regular pacing spikes immediately preceding each QRS complex, which is expected in a client with a functioning permanent pacemaker. The spikes indicate the pacemaker is delivering electrical impulses to stimulate ventricular contraction.

Correct Answer is ["C","D","E","G"]
Explanation
A. Blood glucose level: The client’s blood glucose is 103 mg/dL, which is within normal limits. While monitoring glucose is important for a client with diabetes, this finding does not require immediate follow-up in acute chest pain and suspected myocardial infarction.
B. Bowel sounds: Bowel sounds are present in all four quadrants, indicating normal gastrointestinal function. This assessment is routine and does not necessitate urgent follow-up compared with cardiovascular concerns.
C. Blood pressure: The client’s blood pressure is 164/80 mm Hg, indicating hypertension. Elevated blood pressure can increase myocardial oxygen demand and worsen cardiac ischemia, making it important to address immediately.
D. Pain level: The client reports chest tightness rated 7/10 with radiation to the left arm and associated nausea and diaphoresis. This presentation is characteristic of acute myocardial infarction and requires immediate intervention to reduce myocardial damage and prevent complications.
E. Electrocardiogram findings: The ECG shows tachycardia with ST-segment elevation and T-wave changes, indicating myocardial injury or infarction. Immediate follow-up is critical to initiate reperfusion therapy and prevent further cardiac damage.
F. Lung sounds: Lungs are clear to auscultation, which is expected and does not indicate acute respiratory compromise. No immediate follow-up is required in this context.
G. Troponin T level: Troponin T is elevated at 0.40 ng/mL, confirming myocardial injury. This requires urgent follow-up to guide treatment and assess the extent of cardiac damage.
Correct Answer is ["D","E","F"]
Explanation
A. Temperature: The client’s temperature is stable and within normal postoperative limits, and there are no signs in the assessment suggesting fever or infection as the primary concern. Reassessing temperature does not directly evaluate the effectiveness of interventions related to abdominal distention, pain, or bowel function.
B. Hematocrit: The hematocrit value is mildly low but expected after surgery and shows no indication of acute bleeding or fluid imbalance requiring reevaluation. Monitoring hematocrit will not provide information about the effectiveness of interventions for abdominal symptoms or pain management on postoperative day 3.
C. Urine output: The output is currently high (66.7\ mL/hr). While continuous monitoring is always necessary, the primary focus of re-evaluation after intervening for the GI issue is not the urine output.
D. Abdomen: The client has abdominal distention, hypoactive bowel sounds, and ongoing severe pain, indicating possible ileus or obstruction. Reassessing the abdomen allows the nurse to evaluate whether interventions are improving bowel motility and reducing gastrointestinal distress.
E. Pain rating: The client continues to experience severe pain despite medication, suggesting limited response to current interventions. Reassessing pain helps determine whether additional or alternative pain management measures are required and whether abdominal pathology is worsening.
F. Flatus: The presence or absence of flatus is a key indicator of returning bowel function following abdominal surgery. Reassessing flatus helps evaluate whether interventions are improving gastrointestinal motility and reducing the risk of postoperative ileus or obstruction.
G. Oxygen saturation: The client’s oxygen saturation is stable, and no respiratory issues are noted in the assessment. Reassessing oxygen saturation does not provide meaningful information about the effectiveness of interventions focused on abdominal symptoms and pain.
