Physiological AdaptationQuestion 769 of 2368

A healthy 22-year-old client has an irregular rhythm on the monitor. The rate rises with each inspiration and slows with each expiration. How should the nurse interpret this finding?

  1. It indicates ventricular tachycardia needing cardioversion
  2. It indicates atrial fibrillation needing anticoagulation
  3. It indicates second-degree block needing a pacemaker
  4. It is a normal finding in young, healthy adults
Show answer

Correct answer: It is a normal finding in young, healthy adults

Respiratory sinus arrhythmia is typically normal in young, healthy adults because the rhythm follows the breathing cycle.
