A nurse is providing teaching to a client who has a new permanent pacemaker. Which of the following statements by the client indicates an understanding of the teaching?

A permanent pacemaker is an implanted electronic device used to regulate heart rhythm in clients with bradyarrhythmias or conduction disorders. Postoperative teaching focuses on preventing device interference, protecting the insertion site, and gradually resuming activity. Clients must also be educated about electromagnetic interference (EMI) and proper device precautions to ensure safe long-term function. Understanding these instructions helps prevent complications and ensures effective pacing. A. Resuming physical activity within 2 weeks is not fully accurate because clients are typically advised to avoid strenuous arm movements on the affected side for several weeks to allow proper lead stabilization. Activity is gradually increased based on provider instructions. Early unrestricted activity may dislodge pacing leads. B. Holding the cellphone on the opposite side of the pacemaker demonstrates correct understanding of electromagnetic interference precautions. Although modern devices are well shielded, keeping electronic devices away from the pacemaker site reduces the risk of interference with device function. This reflects appropriate patient education. C. Avoiding microwave oven use is no longer necessary with modern pacemakers because they are designed to withstand household electromagnetic fields. Clients can safely use microwaves as long as the device is functioning properly. This statement reflects outdated information. D. Covering the pacemaker with a dressing when showering is unnecessary after the incision has healed. Once the surgical site is no longer at risk for infection, routine showering without dressings is allowed. Excessive covering is not part of standard long-term care instructions.
