EMR 9.0 Principles of Airway Management and Ventilation (2)

Front

What is the purpose of suctioning? It includes the removal of:

Back

blood, vomitus, and other secretions.

Answer explanation

The purpose of suctioning is to clear the airway by removing blood, vomitus, and other secretions that can obstruct breathing. This is essential for maintaining a clear airway, unlike the other options listed.

Front

When suctioning an adult patient who is unconscious, never suction for longer than _____ seconds at a time.

Back

15

Answer explanation

When suctioning an unconscious adult, it's crucial to limit suction time to prevent hypoxia. The recommended maximum duration is 15 seconds to ensure patient safety and adequate oxygenation.

Front

Atmospheric air contains _____ oxygen.

Back

21%

Answer explanation

Atmospheric air contains approximately 21% oxygen, which is essential for respiration in most living organisms. The other options, such as 10%, 16%, and 25%, do not accurately represent the oxygen concentration in the atmosphere.

Front

Rescue breathing is:

Back

the application of positive pressure ventilations.

Answer explanation

Rescue breathing specifically refers to the application of positive pressure ventilations to assist someone who is not breathing. It does not involve restarting heart rhythms or restoring both heart and breathing functions.

Front

When performing the head-tilt/chin-lift maneuver on an adult, tilt the head:

Back

as far back as possible

Answer explanation

The head-tilt/chin-lift maneuver requires tilting the head as far back as possible to open the airway. This position helps prevent the tongue from obstructing the airway, making it the correct choice.

Front

The recommended method for opening the airway of a patient with a possible neck or spine injury is the __________ maneuver.

Back

jaw-thrust

Answer explanation

The jaw-thrust maneuver is the preferred method for opening the airway in patients with potential neck or spine injuries, as it minimizes movement of the cervical spine, reducing the risk of further injury.

Front

Clinical death occurs when the patient's:

Back

heart beat and breathing have stopped.

Answer explanation

Clinical death is defined as the cessation of both heartbeat and breathing. This means that the correct answer is when the heart beat and breathing have stopped, indicating a loss of vital functions.

Front

A pocket face mask allows the rescuer to provide ventilations while minimizing:

Back

direct contact with the patient's mouth and nose.

Answer explanation

A pocket face mask minimizes direct contact with the patient's mouth and nose, which helps reduce the risk of infection for the rescuer while still allowing effective ventilations.

Front

During rescue breathing, you should check for adequate breathing by: looking for chest rise and fall, listening for airflow, and observing skin color.

Back

looking for chest rise and fall, listening for airflow, and observing skin color.

Answer explanation

The correct choice includes all three methods: looking for chest rise and fall, listening for airflow, and observing skin color. These indicators together help assess if rescue breathing is effective.

Front

If an infant becomes unresponsive before you can clear an airway obstruction, you should first:

Back

place her on a firm surface and begin chest compressions.

Answer explanation

If an infant is unresponsive, placing her on a firm surface and beginning chest compressions is crucial to restore circulation and oxygenation, especially if airway obstruction is suspected.
