Which dysrhythmia should the RN monitor for in a patient after lung resection surgery?

1. S.V.T.

2. Sinus bradycardia

3. V.Fib

4. P.V.C.

The correct answer is: S.V.T.

After lung resection surgery, the patient is at an increased risk for several complications, including dysrhythmias. The correct answer relating to the specific concern following this type of surgery is supraventricular tachycardia (SVT). Patients who have undergone lung surgery may experience various triggers for SVT, such as pain, hypoxia, or fluid shifts. The stress of surgery, along with the potential for electrolyte imbalances and respiratory changes, can contribute to the development of this tachyarrhythmia. Monitoring for SVT is crucial because it can lead to decreased cardiac output and worsen the hemodynamic status of the patient, impacting their recovery. While other dysrhythmias like sinus bradycardia, ventricular fibrillation (V.Fib), and premature ventricular contractions (PVCs) may occur in the postoperative setting, SVT is particularly relevant due to its link with stress from surgery, the postoperative state, and the physiological responses that can occur after lung resection. Understanding the specific risks associated with such a surgical procedure helps the nursing staff focus their monitoring efforts on the most likely complications.
