General Concepts Chapter 1 Flashcards
In which locations do most out-of-hospital cardiac arrests occur?
Homes
Which is the most common cause of cardiac arrest in children?
Respiratory failure/shock
What is the third link in the adult out-of-hospital Chain of Survival
Rapid Defibrillation
Which statement best describes sudden cardiac arrest?
When an abnormal rhythm develops and the heart stops beating unexpectedly
A 53-year old man suddenly collapses and becomes unresponsive. You witness him collapse and are the first rescuer to arrive at the scene. You find him lying motionless on the floor.
Which is the first action you should take in this situation?
Verify that the scene is safe for you and the victim.
A 53-year old man suddenly collapses and becomes unresponsive. You witness him collapse and are the first rescuer to arrive at the scene. You find him lying motionless on the floor.
The man doesn’t respond when you touch his shoulders and shout, “Are you OK?” What is your best next action?
Shout for nearby help.
Several rescuers respond, and you ask them to activate the emergency response and retrieve the AED and emergency equipment. As you check for a pulse and breathing, you notice that the man is gasping for air and making “snorting” sounds. You do not feel a pulse. What is your next best action?
Start high-quality CPR, beginning with chest compression.
What is the ratio of chest compression to breaths when providing CPR to an adult?
30 compression’s to 2 breaths.
What are the rate and depth for chest compression on an adult?
A rate of 100 to 120 compression’s per minute and a depth of at least 2 inches.
What action should you take when more rescuers arrive?
Assign tasks to other rescuers and rotate compressors every 2 minutes or more frequently if needed to avoid fatigue.
If you suspect that an unresponsive victim has head or neck trauma, what is the preferred method for opening the airway?
Jaw thrust
What is the most appropriate first step to take as soon as the AED arrives at the victims side?
Power on the AED
Which step is one of the universal steps for operating an AED?
Placing the pads on the victim’s bare chest.
If a victim of cardiac arrest has an implanted pacemaker or defibrillator, what special steps should be taken?
Avoid placing the AED pad directly over the implanted device.
What action should you take when the AED is analyzing the heart rhythm.
Stand clear of the victim.
After performing high-quality CPR for 5 minutes, the team leader frequently interrupts chest compressions to check for a pulse even though the victim has no organized rhythm when the AED analyzes the rhythm. Which action demonstrates constructive intervention?
Suggest to resume chest compression’s without delay
The team leader asks you to perform bag-mask ventilation during a resuscitation attempt, but you have not perfected that skill. What would be an appropriate action to acknowledge your limitations?
Tell the team leader that you are not comfortable performing that task.
What is the appropriate action to demonstrate closed-loop communication when the team leader assigns you a task?
Repeat back to the team leader the task you were assigned.
What is the correct compression-to-ventilation ratio for a single rescuer of a 3-year old child?
30 compressions to 2 breaths
What is the correct compression-to-ventilation ratio for a 7-year old child when 2 or more rescuers are present?
15 compressions to 2 breaths
For what age victim is the 2-thumb-encircling hands technique recommended when 2 or more rescuers are present?
An infant younger than 3 years
What is the correct chest compression depth for a child?
At least one third the depth of the chest or about 2 inches.
What i the correct chest compression depth for an infant?
At least one third the depth of the chest, or about 1 1/2 inches.
What should you do when using an AED on an infant or a child less than 8 years of age?
Use adult AED pads if the AED does not have child pads.
