A nurse is reinforcing teaching with a client who is scheduled for implantation of a vagus nerve stimulator. Which of the following statements should the nurse include in the teaching?

Choice A reason: Extreme fatigue for several weeks is not a common side effect associated with the implantation of a vagus nerve stimulator. While patients may experience some discomfort and mild fatigue immediately following surgery, it is typically short-term. Prolonged extreme fatigue is not a standard outcome and would warrant further medical evaluation if it occurs. Choice B reason: Hoarseness or changes in voice is a common side effect after the implantation of a vagus nerve stimulator. The stimulator affects the vagus nerve, which is close to the vocal cords. As a result, stimulation can lead to changes in voice, including hoarseness. Patients should be informed of this potential side effect so they are not alarmed if it occurs. Choice C reason: It is unrealistic to expect depression to improve within 72 hours after the implantation of a vagus nerve stimulator. While this treatment can be effective for certain individuals with treatment-resistant depression, it generally takes several weeks to months for patients to notice significant improvement in their symptoms. Setting realistic expectations is crucial for patient adherence and satisfaction with the treatment. Choice D reason: Patients should not assume they can schedule an appointment at any time to turn off the device. The vagus nerve stimulator is implanted as part of a treatment plan, and any changes to its operation should be thoroughly discussed with and managed by the healthcare provider. Turning off the device without proper consultation can impact the effectiveness of the treatment and the patient’s overall health.
