2“I’ll tighten the valve stem as much as I can so it won’t come loose.”

3“I’m going to leave the regulator set to 15 LPM so it will be ready when we need it.”

4“I’ll stand the oxygen tank on the floor beside the stretcher so everyone will know where it is.”

Answer 1

1“I’ll place the oxygen tank in its protective case until we need to use it again.”

Question 2

A 74-year-old patient with a history of chronic emphysema is complaining of sudden onset of shortness of breath. They appear to be in acute respiratory distress. Physical exam of the anterior chest wall reveals crepitus. Based on the patient’s history and physical exam, you would suspect which of the following conditions?
-Acute bronchitis
-Congestive heart failure
-Spontaneous pneumothorax
-Carbon monoxide poisoning

Answer 2

Spontaneous pneumothorax

Question 3

Which of the following actions causes an individual to inhale?

Answer 3

The diaphragm contracts and flattens.

Question 4

You are correctly performing the jaw-thrust maneuver when you:

Answer 4

open the patient’s airway by slightly pushing down on the forehead and thrusting the jaw upward.

Question 5

What is the most common oxygen delivery device used by OEC Technicians?

Answer 5

A nonrebreather mask

Question 6

Despite coaching and explaining the benefits of a nonrebreather face mask, a patient with chest pain panics and states that they cannot tolerate the mask over their face. The more that the patient panics, the worse the chest pain becomes. The best course of action is to:

Answer 6

disconnect the nonrebreather and replace it with a nasal cannula.

Question 7

You are documenting your assessment of the patient who just left in an ambulance. The patient told you that they felt short of breath. You would document this as:

Answer 7

dyspnea.

Question 8

You have been asked to put a patient on a nonrebreather mask at 15 LPM. After you have finished attaching the regulator to the oxygen cylinder, your next step is to:

Answer 8

turn the valve stem on the top of the cylinder using a special oxygen wrench or key.

Question 9

You appropriately size a nasopharyngeal airway by measuring the:

Answer 9

distance from the patient’s nose to the earlobe.

Question 10

You are called to assist a 16-year-old who is reportedly having trouble breathing. Your assessment reveals an anxious patient with rapid respirations who is complaining of pins and needles around their lips. Based on your training you suspect that:

Answer 10

these findings will disappear if they slow the rate of breathing because they are most likely hyperventilating.

Question 11

What is the correct sequence for the passage of air into the lungs once it passes the pharynx?

Answer 11

Larynx, trachea, bronchi, alveoli

Question 12

Which of the following respiratory rates may signify significant respiratory issues in an adult?
-More than 20 respirations per minute
-Fewer than 8 respirations per minute
-More than 24 respirations per minute
-Fewer than 12 respirations per minute

Answer 12

Fewer than 8 respirations per minute

Question 13

During a scene size-up, which of the following observations most strongly suggests that your adult patient is suffering from an acute respiratory emergency?
1The patient’s respiratory rate is 20.
2The patient is holding a metered-dose inhaler.
3The patient is in the tripod position.
4The patient’s hands are trembling.

Answer 13

The patient is in the tripod position.

Question 14

For what scenario would a placement of an oropharyngeal airway indicated?

Answer 14

An unresponsive patient who has neither a gag reflex nor a cough reflex

Question 15

You have been asked to teach a new patroller how to put a patient in the recovery position:

Answer 15

Turn the patient on their side and flex their upper leg so that it anchors them on their side

Question 16

Which of the following statements shows that the OEC technician understands how to suction patients properly in a field setting?
1”When there is active bleeding in the mouth, I may need to use gravity and suction concurrently.”

2”It is helpful to pour sterile water into a patient’s mouth to liquefy vomit and make it easier to suction out.”

3”A rigid suction catheter is affected more by temperature than a flexible catheter, and, therefore, flexible catheters should be chilled.”

4”To thoroughly suction a patient, I insert the rigid tip of the catheter past the base of the tongue and into the pharynx.”

Answer 16

“When there is active bleeding in the mouth, I may need to use gravity and suction concurrently.”

Question 17

When the diaphragm and intercostal muscles relax, which event occurs?

Answer 17

Exhalation

Question 18

If a patient gags while you are inserting an oropharyngeal airway, you should remove the airway and:

Answer 18

have suction ready.

Question 19

Which of the following statements about respiratory accessory muscles is not correct?
1They bring more oxygen into the body by helping the chest wall expand more fully.

2They include chest, shoulder, and abdominal muscles.

3They decrease negative internal chest pressure to draw more air into the lungs.

4They are recruited whenever the body’s oxygen demand exceeds oxygen availability.

Answer 19

They decrease negative internal chest pressure to draw more air into the lungs.

Question 20

Hyperventilation syndrome is a common psychological condition that:

Answer 20

results in abnormally low blood carbon dioxide levels.
