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

Rationale: A. "The pacemaker will deliver a shock if I develop a dysrhythmia.": Permanent pacemakers do not deliver shocks; they provide low-energy electrical impulses to maintain an adequate heart rate. Devices that deliver shocks to correct dangerous rhythms are implantable cardioverter-defibrillators (ICDs). Confusing a pacemaker with an ICD indicates a misunderstanding. B. "I need to check my pulse rate every day for a full minute.": Daily pulse monitoring helps the client ensure the pacemaker is effectively maintaining heart rate within the prescribed range. Assessing the pulse for a full minute provides accurate detection of bradycardia, missed beats, or irregularities, allowing early identification of potential device malfunction. C. "I need to maintain pressure over the pacemaker site with an elastic bandage.": Applying pressure with a bandage is not recommended and could disrupt the device’s positioning, interfere with healing, or cause skin breakdown. Post-implant care focuses on keeping the site clean, dry, and avoiding heavy lifting with the affected arm. D. "When a microwave oven is in use, I need to stay out of the room.": Modern pacemakers are shielded against electromagnetic interference from household appliances, including microwave ovens. It is safe for clients to use microwaves and remain in the room during operation. There is no need to avoid normal household electrical devices.
