DHA Staff Nurse - Free Test Sample Questions

Your patient has been fitted with a pacemaker to correct a serious dysrhythmia. The pacemaker that was implanted fires at a constant rate. You recognize that this type of pacemaker is which of the following types?

Correct Answer:
fixed


acemakers are medical devices used to treat arrhythmias, which are problems with the rate or rhythm of the heartbeat. when a person’s heart does not beat normally, doctors may recommend the implantation of a pacemaker. the function of a pacemaker is to electrically stimulate the heart to maintain a proper heart rate and rhythm.

acemakers come in different types, chiefly categorized into fixed-rate pacemakers and demand-rate pacemakers. a fixed-rate pacemaker, also known as an asynchronous pacemaker, continuously sends electrical impulses at a steady rate, regardless of the patient's natural heart activity. this means it does not sense the heart's own electrical activity and fires at a preset rate typically determined by the healthcare provider based on the patient’s typical needs.

acemakers are crucial when the heart’s natural pacemaker (the sinoatrial node) is dysfunctional or when the electrical pathways are blocked. an asynchronous or fixed-rate pacemaker is commonly used in situations where the heart’s intrinsic electrical activity is minimal or unreliable, and there is a need for a consistent, steady pacing to maintain adequate heart function.

acemakers are different from demand pacemakers, or synchronous pacemakers, which monitor the heart's natural rhythm and only send electrical impulses if the heart rate falls below a preset threshold. these pacemakers are equipped with sensors that detect the heart's intrinsic electrical activity and initiate pacing only when necessary, thereby working in sync with the heart's natural pacemaker.

acemakers have evolved over the years with advancements in technology. today, most pacemakers are demand pacemakers due to their ability to work in conjunction with the natural heart rhythm, which helps conserve battery life and reduces unnecessary pacing, thereby providing a more natural heart rhythm experience for the patient. however, fixed pacemakers are still used in specific clinical situations where constant pacing is required.

acemakers are typically implanted under the skin in the chest area, and wires (leads) are threaded through the veins to the heart to deliver the electrical impulses that stimulate heartbeats. regular check-ups are essential to ensure the pacemaker functions correctly and adjustments are made as needed for optimal patient health.
