Emergency Cardiovascular Life Support Practice Questions:
1. Do Respiratory Therapists play a vital role in emergency cardiovascular life support?
Yes, yes they do. And that is what we’re going to be discussing in this study guide. 🙂
2. What is the goal of basic life support?
The goal of basic life support (BLS) is to restore ventilation and circulation to victims of airway obstruction and respiratory or cardiac arrest.
3. What is CPR?
Cardiopulmonary resuscitation (CPR) basic emergency procedure for life support, consisting of artificial respiration and manual external cardiac massage.
4. What is the most common cause of sudden death in adults?
Coronary artery disease; accidents are the most common cause of death in young people.
5. What are the fundamental steps of basic CPR of health care providers for a witnessed cardiac arrest?
(1) Confirm unresponsiveness. (2) Call for help and activate the EMS system. (3) Check for a pulse (less than 10 seconds). (4) Perform 30 cardiac compressions. (5) Give two 1-second breaths to produce visible chest rise. (6) Initiate automated external defibrillation immediately
(perform defibrillation as soon as possible).
6. During CPR, how many compressions and breaths should you give?
Five cycles of 30 compressions to 2 ventilations CPR for adults should be given between attempts at defibrillation using only one shock followed immediately by chest compressions.
7. Evaluating the effectiveness of CPR is important and requires rescuers to watch for what?
Visible chest rise and fall with ventilation and to push hard and fast when delivering chest compressions.
8. What are the complications of CPR?
Worsening of potential neck injuries, gastric inflation and vomiting, and internal trauma during chest compressions. Correct technique minimizes the risk for such complications.
9. The Respiratory Therapist is most often called on to do what during CPR?
Establish an airway and ventilation with elevated FiO2 during ACLS of hospitalized patients. Most often, knowledge and skill with bag-valve devices and oropharyngeal airways are required. Special care should be taken not to hyperventilate the patient during or after cardiac arrest.
10. Common pharmacologic agents used during ACLS include?
Atropine for bradycardia, epinephrine and amiodarone or lidocaine for ventricular arrhythmias, and epinephrine or vasopressin for cardiac arrest and hypotension.

11. In the post-resuscitative phase, the Respiratory Therapist may need to do what?
Help maintain normal ventilation and oxygenation and assist the physician and nurses in monitoring the patient’s condition.
12. The Respiratory Therapist is often involved in care after cardiac arrest of a victim who does what?
Responds favorably to CPR.
13. What is an abdominal thrust?
External pressure forcefully exerted on the abdomen, under the diaphragm, to expel obstructing objects from the upper airway
14. What is ACLS?
It stands for Advanced Cardiac Life Support and includes emergency medical procedures beyond basic life support; includes intravenous fluid life establishment, possible defibrillation, drug administration, control of cardiac arrhythmia, and use of ventilation equipment. This procedure usually needs direct or indirect supervision of a physician.
15. Why are chest compressions performed?
To provide adequate circulation.
16. How to perform chest compressions?
Compress the sternum 2 inches at a rate of 100 compressions per minute. If there is an interruption, resume quickly.

23. What is CPR?
It is the basic emergency procedure for life support, consisting of artificial respiration and manual external cardiac massage.
24. What is defibrillation used for?

26. Electrical shock can cause what?
Cardiac or respiratory arrest. Remove the patient from the electrical source, turn off electricity, and maintain rescuer safety.
27. Exhaled air provides what percentage of oxygen?
28. What is gastric inflation?
It is the introduction of air into the stomach and intestine and is caused by prolonged mouth to mouth. It occurs 17% of cases. For prevention, use a mask.
29. Health care providers should use what ratio for adult and children during CPR?
30:2, compressions to ventilations.
30. Health care providers should use a ratio of what for infants?
3:1, compressions to ventilations (2 rescuers).
31. What are the CPR considerations for patients with implanted pacemakers and defibrillators?
Compressions should be done, generally, do not interfere with compressions, pads should be placed at least 1 inch from the location of pacemaker or defibrillator.
32. What are some considerations for performing infant compressions?
Use the lower half of sternum, place index finger at the nipple line, then tall and ring finger are used for the compressions, use the other hand to maintain head position, compress 1.5 in. at 100/minute.
33. In general, how should you give compressions on an adult?
Hard and fast.
34. What are the most effective instructions for giving CPR?
Give 100 compressions per minute, depth of 2 inches, allow the chest to recoil and minimize interruptions.
35. What is mouth to mouth ventilation?
The rescuer uses deeper breath than normal 700-1000ml, delivers breath over 1 second. There should be a visible chest rise.
36. What should you do if the patient has a pulse but is not breathing?
Start ventilation immediately and 8-10 breaths/minute.
37. Providing artificial ventilation must take place how quickly to prevent biologic death?
Within 4-6 minutes.
38. When should pulse and rhythm checks after the shock be performed?
After 5 cycles of CPR have been completed.
39. Pulseless ventricular rhythms are what?
They are the first manifestation of cardiac arrest in 25% of cases.
40. How to restore the airway?
Inspect for a neck/facial injury, move the victim to the supine position, movement of lower jaw and extension of neck pulls the tongue out of the way, head-tilt chin-lift, jaw thrusts.
41. How to restore ventilation?
Asses for breathing, check for chest movement; it takes no longer than 3-5 minutes.
42. What is the leading cause of death in the United States?
Sudden Cardiac Arrest.
43. What are the steps for administering BLS as a single practitioner?
(1) Check for lack of movement, response, and not normal breathing or only gasping. (2) No response, check for pulse within 10 seconds. (3) Activates emergency response system. (4) If no AED, start compressions and rescue breathing at a ratio of 30:2 for adult cardiac arrest. (5) Open the airway and check breathing. (6) If the patient is not breathing, give 2 breaths that can produce a rise of the chest and resume compressions. (7) When AED arrives with the response team, perform shock.
44. What is synchronized cardioversion?
A counter-shock synchronized with the heart’s electrical activity.
45. When do you stop ALS?
When there is a spontaneous pulse and breathing, pronounced death by the doctor, or if the patient has a DNR status.
46. When is mouth to nose ventilation used?
Trismus (involuntary contraction of the jaw muscles-lock jaw), traumatic jaw, mouth injury, or if the mouth seal is difficult to maintain.
47. When should you start to use chest compressions on a neonate?
If the heart rate decreases to less than 60 beats per minute despite adequate ventilation with 100% oxygen.
48. With two rescuers, how often should you switch positions?
Every 5 cycles, or about every 2 minutes.
49. An advanced airway will allow the rescuer to achieve one or more of the following goals:
Deliver ventilations that are nonsynchronous with chest compressions, restore airway patency, maintain adequate ventilation, isolate and protect the airway from aspiration, provide access for clearance of secretions, and provide an alternate route for administration of selected drugs.
