NURSING 2900, THEORY EXAM 1:
Perfusion/Oxygenation/Tissue Integrity Questions
with Correct Answers
Sinus Rhythms
Atrial Fibrillation
Atrial Flutter
Junctional (AV note)
Paroxysmal Supraventricular Tachycardia Correct Answer ✓✓ What are
the supraventricular waves (normal QRS complexes)?
Premature ventricular contractions
Ventricular Tachycardia
Ventricular Fibrillation Correct Answer ✓✓ What are the ventricular
rhythms?
fast, regularly irregular atrial rate (p-wave), looks like there are multiple
p-waves between each QRS Correct Answer ✓✓ What are the
characteristics of atrial fibrillation?
atrial fibrillation Correct Answer ✓✓ Which rhythm places a client at
increased risk for thromboemboli and stroke?
EKG
Cardioversion
,Catheter albation
Assess for decreased cardiac output, underlying cause, labs
Beta blockers Correct Answer ✓✓ What interventions are used to treat
atrial fibrillation?
the rate of the QRS complex is over 100bpm; regular rhythm Correct
Answer ✓✓ What are the characteristics of ventricular tachycardia?
sustained ventricular tachycardia causes decreased cardiac output and is
a medical emergency Correct Answer ✓✓ Why should the nurse be
concerned about ventricular tachycardia?
ventricular tachycardia, but the QT wave is prolonged Correct Answer
✓✓ Torsades de pointes is what type of dysrhythmia?
EKG
Cardioversion (if hemodynamically stable)
Defibrillation
,Implanted cardioverter
Assess for decreased cardiac output, underlying cause, and labs
IA (quinidine, procanamide), IB (lidocaine, phenytoin), potassium
channel blockers Correct Answer ✓✓ The nurse can expect what
interventions for the client with ventricular tachycardia?
no electrical activity as a result of cardiac death/MI Correct Answer ✓✓
What is asystole?
if there is any question of whether the client might actually be in fine v-
fib; otherwise asystole is unshockable Correct Answer ✓✓ Why would
someone with asystole be defibrillated?
chaotic and rapid ventricular activity; when a client is in v-fib there is
NO cardiac output Correct Answer ✓✓ What is characteristic of
ventricular fibrillation?
CPR/defibrillation
Epinephrine, amiodorone Correct Answer ✓✓ What interventions
should be implemented for the client in ventricular fibrillation?
, continued electrical activity despite the fact that the heart is not
pumping; client will be unconscious, apneic, and pulseless Correct
Answer ✓✓ What is pulseless electrical activity (PEA)?
Hypovolemia
Hypoxia
H+ ion excess (acidosis)
Hypoglycemia
Hypokalemia
Hyperkalemia
Hypothermia
Tension Pneumothorax
Tamponade (cardiac)
Toxins
Thrombosis (pulmonary)
Thrombosis (acute MI) Correct Answer ✓✓ What can cause pulseless
electrical activity (H&T's)?
saline or lactated ringers bolus Correct Answer ✓✓ PEA caused by
hypovolemia can be treated with...
hyperventilation, sodium bicarbonate Correct Answer ✓✓ PEA caused
by acidosis can be treated with...
