HESI RN CRITICAL CARE EXAM REVIEW
2026 COMPLETE TEST BANK 350
QUESTIONS WITH VERIFIED CORRECT
ANSWERS
⩥ Atrial Fibrillation. Answer: Rapid, random, ineffective *contractions
of the atrium*
No P Waves, *Normal QRS w/ irreg intervals*
Risk for thrombi
Tx: anti coagulants (Heparin), TEE, Synchronized Cardioversion
⩥ Atrial Flutter. Answer: No P Waves, QRS at reg intervals
Sawtooth or FLUTTER WAVES
Tx: Anti coagulants, TEE, synchronized cardioversion
Adenosine, beta blockers, calcium channel blockers, digitalis (digoxin)
(Fluttering in a circle singing "ABCDs")
,⩥ Supraventricular Tachycardia (SVT). Answer: Episodes of abnormally
fast/racing heartbeat (between 150-250)
Normal QRS w/ reg intervals
Tx: first - valsalva's maneuver, carotid massage, ice to face
*Adenosine*, beta blockers, calcium channel blockers, dig
⩥ Premature Atrial Complexes (PAC). Answer: stimulus can be caffeine,
nicotine, alcohol stress
common but if pt has cardiac probs it can cause ischemia
usually asymptomatic
tx: take away trigger
⩥ Ventricular Tachycardia (V-tach). Answer: Can deteriorate to V Fib
Tx: check pulse and LOC... if they have a pulse: synchronized
cardioversion
Vasopressin, Lidocaine, Amiodarone, Magnesium, Epi (V TACH = V
LAME)
if pulseless = CPR and defibrillation
⩥ 3 or more PVCs in a row. Answer: V-tach
, ⩥ Ventricular Fibrillation (V-fib). Answer: abnormal heart rhythm which
results in quivering of ventricles
*FATAL RHYTHM*
Tx: *Defibrillation*, CPR
⩥ Asystole. Answer: no electrical impulses
unconscious and pulseless
*DO NOT START CPR UNTIL YOU CHECK TWO LEADS*
TX: CPR, epi or vasopressin
⩥ Cardioversion. Answer: - Elective procedure (informed consent is
needed)
- Synchronized with QRS
- *50-100* Joules
⩥ Defribrillation. Answer: - Emergency (call code)
- V-fib / V-Tach
- Begin with 200 joules (can go up to 300)
