The nurse admits a patient into the emergency department who complains of light-headedness and nausea. During the assessment, the nurse determines that the radial pulse is 42 and regular, the QRS complex is within normal limits, and there is no measurable PR interval because there is no consistent relationship between the P waves and the QRS complexes. How would the nurse interpret this dysrhythmia?

The description provided suggests third-degree AV block, also known as complete heart block, where there is no consistent relationship between P waves and QRS complexes, resulting in a slow and irregular heart rate. This condition can lead to symptoms such as lightheadedness and nausea. Sinus bradycardia and sinus arrest both involve a consistent relationship between P waves and QRS complexes, and supraventricular tachycardia involves a rapid heart rate.
