A patient develops the dysrhythmia shown below:Blood pressure is 83/40.

The dysrhythmia shown in the image is likely a rapid ventricular tachycardia (VT), given the hemodynamic instability (BP 83/40, patient pale, diaphoretic, lethargic, and disoriented). Synchronized cardioversion at 100 joules is the appropriate treatment for unstable VT, as it can effectively terminate the arrhythmia and restore normal sinus rhythm, addressing both the dysrhythmia and the patient's symptoms.References: = CCRN Exam Handbook, page 33
