Advanced Cardiac Life Support (ACLS)
Exam Practice Tests
Course Introduction
Advanced Cardiac Life Support (ACLS) is an intensive course designed for healthcare professionals to enhance their skills in the management of adult patients experiencing cardiac arrest and other cardiovascular emergencies. The course covers advanced interventions such as airway management, pharmacology, recognition and management of arrhythmias, effective resuscitation team dynamics, post-cardiac arrest care, and the application of algorithms for cardiac arrest, acute dysrhythmias, stroke, and acute coronary syndromes. Through a combination of lectures, interactive case studies, and hands-on simulations, participants gain the critical knowledge and practical skills needed to lead and respond effectively during complex cardiac emergencies in hospital or prehospital settings.

Sample Questions
Q1) Stimulation of beta-adrenergic receptor sites will result in peripheral vasoconstriction.
A)True
B)False
Answer: False
Q2) What is meant by the term ejection fraction?
Answer: Ejection fraction is the percentage of blood pumped out of a heart chamber with each contraction.Each ventricle holds about 150 mL when it is full; they normally eject only about half this volume (70 to 80 mL)with each contraction.
Q3) Rapid ejection of blood from the ventricular chambers of the heart occurs because the _____ and _____ valves open.
A) pulmonic; aortic
B) tricuspid; mitral
C) pulmonic; mitral
D) tricuspid; aortic
Answer: A
Q4) The right atrium receives blood low in oxygen from three vessels.Name them.
Answer: Superior vena cava,inferior vena cava,and coronary sinus
