Answer 1

rigor mortis

Question 2

Blood settling to the lowest point of the body, causing discoloration of the skin; a definitive sign of death

Answer 2

dependent lividity

Question 3

Advanced life-saving procedures, some of which are now being provided by the EMT

Answer 3

advanced life support

Question 4

Noninvasive emergency life-saving care that is used to treat medical conditions, including airway obstruction, respiratory arrest and cardiac arrest

Answer 4

basic life support

Question 5

A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow

Answer 5

ischemia

Question 6

Rapid or deep breathing that lowers the blood carbon dioxide level below normal

Answer 6

hyperventilation

Question 7

A valve device placed between the endotracheal tube and a bag-mask device that limits the amount of air entering the lungs during the recoil phase between chest compressions

Answer 7

impedance threshold device

Question 8

A circumferential chest compression device composed of a constricting band and backboard that is either electrically or pneumatically driven to compress the heart by putting inward pressure on the thorax

Answer 8

load-distributing band

Question 9

A technique that involves compressing the chest and then actively pulling it back up to its neutral position or beyond

Answer 9

active compression-decompression CPR

Question 10

A harsh, high-pitched respiratory sound, generally heard during inspiration, that is caused by partial blockage or narrowing of the upper airway

Answer 10

stridor

Question 11

A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation

Answer 11

gastric distention

Question 12

A side-lying position used to maintain a clear airway in unresponsive patients who are breathing adequately and do not have suspected injuries to the spine, hips or pelvis

Answer 12

recovery position

Question 13

The return of a pulse and effective blood flow to the body in a patient who was previously in cardiac arrest

Answer 13

return of spontaneous circulation

Question 14

The combination of chest compressions and rescue breathing used to establish adequate ventilation and circulation in a patient who is not breathing and has no pulse

Answer 14

cardiopulmonary resuscitation

Question 15

A device that depresses the sternum via a compressed gas-powered or electric-powered plunger on a backboard

Answer 15

mechanical piston device

Question 16

The exchange of air between the lungs and the environment

Answer 16

ventilation

Question 17

A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients

Answer 17

head tilt-chin lift maneuver

Question 18

The total percentage of time during a resuscitation attempt in which active chest compressions are being performed

Answer 18

chest compression fraction

Question 19

Technique to open the airway by placing the fingers behind the angle of the jaw and bringing the jaw forward; used for patients who may have a cervical spine injury

Answer 19

jaw-thrust maneuver

Question 20

The preferred method to dislodge a severe airway obstruction in adults and children

Answer 20

abdominal thrust maneuver
