ARRT CI PRACTICE EXAM 2025/2026 QUESTIONS WITH
ANSWERS TAGGED A+
✔✔leads II, III, aVf reflect activity in what wall of the heart - ✔✔inferior
✔✔leads I, aVl, and chest leads v5 and v6 reflect activity in what wall of the heart? -
✔✔lateral
✔✔chest leads v1 and v2 reflect activity in what region? - ✔✔septal
✔✔chest leads v3 &v4 reflect activity in what wall of the heart? - ✔✔anterior
✔✔sign of inferior-posterior MI? - ✔✔ST segment & T wave changes
✔✔sign of ischemia - ✔✔ST elevation occurs in leads V1 to V3
✔✔signs of acute injury - ✔✔ST depression occurs
✔✔signs of infarction on ECG - ✔✔R wave instead of Q wave in leads V1 TO V3
✔✔P-WAVE - ✔✔atrial depolarization
✔✔p-r interval - ✔✔from start of atrial depolarization to start of QRS complex
✔✔QRS complex - ✔✔ventricular depolarization
✔✔systole - ✔✔Contraction of the heart
✔✔normal p-interval in adutls - ✔✔0.18-0.20 seconds
✔✔QRS interval - ✔✔0.07-0.10 seconds
✔✔what do the ST segment and T wave represent - ✔✔diastole
✔✔What are PVCs? - ✔✔premature ventricular contractions- abnormal activity in the
ventricles.
✔✔what does a PVC look like? - ✔✔wide, bizzare QRS?
✔✔what is a unifocal PVC? - ✔✔originating from the same spot each time. So every
PVC looks exactly the same.
, ✔✔what is a multifocal PVC? - ✔✔originating from different points on the ventricles so
the PVCs look different.
✔✔what is hypovolemia? - ✔✔low volume of plasma
✔✔how to treat hypovolemia from ischemia or vasovagal reaction? - ✔✔atropine
✔✔how to treat drug induced hypovolemia? - ✔✔narcan for narcotics and flumazenil for
benzodiazepines
✔✔you see V-FIB, whats next? - ✔✔unsynchronized cardioversion
✔✔persistent VT occurs, what drip might the doctor ask for? - ✔✔amiodarone, 150 mg
IV bolus
✔✔sustained v-tach persists after catheter removal, whats next - ✔✔perform
cardioversion
✔✔what IV drip is an alternative to amiodarone? - ✔✔lidocaine, 1 to 1.5 mg bolus
✔✔patient goes into asystole, whats next? - ✔✔CPR, give epinephrine every 3-5
minutes
✔✔causes of PE? - ✔✔HYPOVOLEMIA, PERICADIAL TAMPONADE, MASSIVE PE
✔✔patient is stable, but in SVT. whats next? - ✔✔synchronized cardioversion
✔✔in SVT, the ventricular response can be controlled by what drug? - ✔✔beta-blocker
or IV diltiazem
✔✔indications for IABP? - ✔✔cardiogenic shock, acute MI w/ complex impairement
✔✔contraindications for IABP - ✔✔abnomaility of femoral/iliac arteries, aortic dissection,
AI
✔✔what does IABP do? - ✔✔lowers myocardial oxygen demand, raises diastolic
pressure and coronary blood flow
✔✔when does the IABP inflate? - ✔✔in diastole at the dicrotic notch
✔✔when does the IABP deflate? - ✔✔just before systole
✔✔what does the impella do? - ✔✔provides direct unloading of LV
