DAANCE PRACTICE EXAM 2025/2026 QUESTIONS WITH
ANSWERS GRADED A+
✔✔Supraventricular foci - ✔✔Central points of origin of dysrhythmias, which are located
above the level of ventricles in the atria

✔✔Ventricular focus(foci) - ✔✔A displaced point of origin for a dysrhythmia that is in the
ventricles

✔✔Sinus rhythms - ✔✔Cardiac rhythms in which the pacemaker is the sinoatrial node

✔✔Atrial (Supraventricular) rhythms - ✔✔Dysrhythmias in which the pacemaker is in the
atria above the level of the ventricles (Supraventricular) area.

✔✔Ventricular rhythms - ✔✔Cardiac dysrhythmia in which the pacemaker is in the
ventricles rather than in the SA node

✔✔Arrest rhythms - ✔✔Cardiac rhythms in which there is a cardiac arrest. Some arrest
rhythms such as pulseless ventricular tachycardia are accompanied by a rhythm
display, but there is no contraction

✔✔Rate of firing in the SA node - ✔✔60-100

✔✔Rate of firing in the atria - ✔✔60-80

✔✔Rate of firing in the AV node - ✔✔40-60

✔✔Rate of firing in the ventricles - ✔✔20-40

✔✔Normal sinus rhythm - ✔✔Regular rhythm with a rate of 60-100 bpm. Has P waves,
QRS complex and T wavs

✔✔Sinus arrhythmia - ✔✔Similar to normal sinus rhythm but with slight variation in rate
with inspiration and expiration

✔✔Sinus bradycardia - ✔✔Similar to normal sinus rhythm except a slower rate of less
than 60 bpm

✔✔Sinus tachycardia - ✔✔Similar to normal sinus rhythm except for an increase in rate
of greater than 100 bpm but usually less than 150 bpm

✔✔Atrial and superventricular rhythms - ✔✔Those above the level of the ventricles
