EMT Airways and Breathing Practice Test 3

This is a timed quiz. You will be given 60 seconds per question. Are you ready?


A 70-year-old patient is complaining of shortness of breath. She has a history of emphysema. You should:

Correct! Wrong!

While it may be true that providing high levels of oxygen over prolonged time periods may cause the hypoxic drive to fail, it is a rare occurrence in the prehospital field. With the complaint of shortness of breath, it is better to ensure that the patient is fully oxygenated rather than taking a chance that she is hypoxic. The EMT-Basic is prepared to ventilate the patient if she goes into respiratory arrest due to the high levels of oxygen.

The Sellick's maneuver is designed to:

Correct! Wrong!

The Sellick's maneuver is designed to reduce the risk of vomiting during intubation by directly collapsing the esophagus. In addition, it can also help bring the vocal cords into view.

Cardiac arrest in children is most often caused by:

Correct! Wrong!

The most common complication causing pediatric cardiac arrest is inadequate breathing or other respiratory compromise.

An intervention for someone who is apneic would be?

Correct! Wrong!

Someone who is apneic is not breathing. Therefore any or all of the above would be correct interventions to help this patient.

A spontaneous pneumothorax is ?

Correct! Wrong!

Spontaneous pneumothorax is commonly seen in COPD Patients, but can also be caused by a rupture of certain types of blisters in the lung.

After placing an endotracheal tube and performing an auscultation, you notice lung sounds on the right are present, but lung sounds on the left are absent or diminished. What should you do?

Correct! Wrong!

When you hear lung sounds on the right side and not on the left after an intubation, the likely cause is that you advanced the tube too far and inserted the tube into the right Bronchi. This normally occurs on the right side due to its straighter angle.

You arrive at the scene of an elderly woman who has fallen and injured her ribs. She is breathing very rapidly at a rate of 40 and shallow. How is this a serious life threat?

Correct! Wrong!

In her current state, the patient may not be moving enough air for adequate tissue perfusion.

Which statement about inadequate breathing is correct?

Correct! Wrong!

A respiratory rate that is either too fast or too slow may be a sign of inadequate breathing. Respiratory distress occurs with many medical and trauma problems and spans the age groups, making choice b inaccurate. An increased work (effort) of breathing frequently accompanies inadequate breathing as the patient attempts to compensate, but it should never be considered a “normal sign” as suggested by choice c. Patients may breathe shallowly or deeply for a number of reasons, only one of which is to compensate for an abnormal rate, making choice d inaccurate.

A danger of using a rigid suction catheter with infants and young children is that stimulating the back of the throat can:

Correct! Wrong!

When using a rigid catheter to suction infants and small children, take care not to touch the back of the throat, since stimulation here can cause bradycardia due to stimulation of the vagus nerve.

Paradoxical motion of the chest during exhalation is often caused by what type of injury?

Correct! Wrong!

A Flail Chest occurs when multiple adjacent ribs are broken in multiple places, separating a segment, so a part of the chest wall moves independently. This independent movement is known as Paradoxical motion.

The first step in artificial ventilation with a bagvalve-mask unit in patients with no suspected trauma is to:

Correct! Wrong!

The correct order of steps would be b, c, a, d.

Your patient is a 35-year-old trauma victim who is not breathing. You are unable to open the airway by means of the jaw thrust and suctioning. You should:

Correct! Wrong!

Although the head-tilt/chin-lift is not ordinarily used on trauma patients because it interferes with spinal immobilization and alignment, opening the airway takes priority over all other considerations. Be sure to document your actions in the patient care report.

What is the structure that prevents food and liquid from entering the trachea during swallowing?

Correct! Wrong!

The epiglottis is the leaf-shaped structure that closes off the trachea during swallowing. The larynx is the voice box, the structure that produces speech vibrations; the cricoid cartilage forms the lower portion of the larynx; the diaphragm is a large muscle that contracts to initiate inhalation.

Medical control has ordered you to assist a patient with a metered dose inhaler. Before assisting this patient, you must ensure what

Correct! Wrong!

Before assisting anyone with a metered dose inhaler, you must make sure it is their medication and is not out of date.

The endotracheal tube is primarily intended to:

Correct! Wrong!

By inserting the endotracheal tube in to the trachea, you isolate the trachea from the esophagus. This creates a patent airway.
