Answer

Venturi mask

Question 7

What is the purpose of using a humidifier in oxygen therapy equipment?

Accepted Answer

To prevent nasal dryness

Answer

To enhance oxygen absorption

Answer

Answer

To warm the oxygen

Question 8

In the context of long-term oxygen therapy at home, which type of oxygen delivery device is commonly employed?

Accepted Answer

Nasal cannula, designed for continuous and comfortable delivery of oxygen

Answer

Venturi mask, used to administer precise concentrations of oxygen

Answer

Non-rebreather mask, employed in emergencies to deliver high concentrations of oxygen

Answer

Tracheostomy collar, utilized for long-term ventilation support

Question 9

What is the primary purpose of utilizing a Venturi mask in oxygen therapy?

Accepted Answer

Delivering a precise concentration of oxygen, making it suitable for specific therapeutic needs

Answer

Providing high-flow oxygen therapy, commonly used in emergency situations or for patients with severe respiratory distress

Answer

Treating patients with respiratory distress by providing a high concentration of oxygen

Answer

Preventing aspiration, a condition where foreign substances enter the lungs, which is not a primary function of a Venturi mask

Question 10

When applying a non-rebreather mask, which technique is essential for ensuring effective oxygen delivery?

Accepted Answer

Placing the mask snugly over the patient's nose and mouth to create a proper seal

Answer

Using a reservoir bag to collect exhaled gases, allowing for re-inhalation

Answer

Administering oxygen at a flow rate of 10-15 L/min to deliver high concentrations of oxygen

Answer

Monitoring the patient's breathing and adjusting the flow rate as needed to maintain optimal oxygenation

Question 11

In providing oxygen therapy to a patient experiencing respiratory distress, what should be the initial step to prioritize?

Accepted Answer

Assessing the patient's airway, breathing, and circulation status to ensure their overall stability

Answer

Administering oxygen immediately at a flow rate of 15 L/min via nasal cannula, assuming it will be beneficial

Answer

Applying a non-rebreather mask, which delivers high concentrations of oxygen without the need for initial assessment

Answer

Monitoring the patient's vital signs, but delaying oxygen administration until a thorough assessment is complete

Question 12

Which of the following is NOT a non-invasive oxygen delivery device?

Accepted Answer

Tracheotomy

Answer

Nasal cannula

Answer

Face mask

Answer

Venturi mask

Yes

Question 14

What is the primary purpose of a Venturi mask?

Accepted Answer

To deliver precise oxygen concentrations

Answer

To increase airway pressure

Answer

To humidify inspired gases

Answer

To perform mechanical ventilation

Question 15

Is it necessary to closely monitor a patient receiving oxygen therapy for signs of respiratory distress?

Accepted Answer

Yes

Answer

No

Question 16

What is the recommended target range for oxygen saturation levels in a patient experiencing respiratory distress?

Accepted Answer

94-98%

Answer

88-92%

Answer

99-100%

Answer

100-105%

Question 17

How does pulse oximetry differ from capnography?

Accepted Answer

Pulse oximetry measures oxygen saturation, capnography measures carbon dioxide levels.

Answer

Pulse oximetry measures heart rate, capnography measures respiratory rate.

Answer

Pulse oximetry is an invasive procedure, capnography is non-invasive.

Answer

There is no difference between pulse oximetry and capnography.
