#1

What is the most common method of oxygen delivery in emergency medical care?

Bag-valve-mask
Explanation

Delivers higher tidal volumes and oxygen concentrations.

#2

Which of the following is a characteristic of a Venturi mask?

It delivers oxygen at a fixed concentration
Explanation

Precise oxygen delivery.

#3

What is the main purpose of using a pulse oximeter during oxygen therapy?

To monitor oxygen saturation levels
Explanation

Ensures adequate oxygenation.

#4

Which of the following is a complication associated with high-flow oxygen therapy?

Hypercapnia
Explanation

Excessive CO2 buildup.

#5

In airway management, what is the purpose of the chin lift maneuver?

To maintain alignment of the airway
Explanation

Prevents airway obstruction.

#6

Which of the following is a potential complication of oxygen therapy in patients with chronic obstructive pulmonary disease (COPD)?

Hyperoxemia
Explanation

Excessive oxygen levels.

#7

What is the primary function of a non-rebreather mask in delivering oxygen?

To prevent rebreathing of exhaled air
Explanation

Ensures fresh oxygen supply.

#8

Which of the following oxygen delivery devices is most suitable for providing oxygen therapy to a patient with facial burns?

Tracheostomy mask
Explanation

Protects damaged facial tissue.

#9

What is the primary advantage of using a bag-valve-mask (BVM) device for ventilation?

It can deliver higher tidal volumes and oxygen concentrations
Explanation

Optimal oxygenation and ventilation.

#10

Which of the following is a potential complication of endotracheal intubation?

Pneumothorax
Explanation

Risk of lung puncture.

#11

What is the recommended initial flow rate for oxygen administration via nasal cannula in adult patients?

3-5 L/min
Explanation

Standard starting flow for adults.

#12

Which of the following is a contraindication for the use of a nasopharyngeal airway?

Severe facial trauma
Explanation

Risk of exacerbating injury.

#13

What is the recommended action if oxygen saturation does not improve with oxygen therapy?

Switch to a different oxygen delivery device
Explanation

Alternative method may be more effective.

#14

Which of the following statements regarding high-flow nasal cannula (HFNC) therapy is true?

It provides positive end-expiratory pressure (PEEP) to the airway
Explanation

Maintains airway pressure.

#15

What is the recommended action if a patient receiving oxygen therapy develops signs of oxygen toxicity?

Switch to a lower FiO2 delivery device
Explanation

Reduces oxygen concentration.
