COPD - CCE - Certified Chronic Obstructive Pulmonary Disease Educator Oxygen Therapy and Devices Questions and Answers

Question 1

A patient with COPD is being discharged on long-term oxygen therapy.
As a COPD educator, you review the GOLD guidelines to confirm the qualifying criteria.
Which of the following findings in a stable patient on optimal medical therapy meets the criteria for initiating long-term oxygen therapy to improve survival?

Accepted Answer

PaO2 ≤ 55 mmHg or SpO2 ≤ 88% at rest.

Answer

PaO2 of 65 mmHg or SpO2 of 91% at rest.

Answer

PaO2 of 60 mmHg or SpO2 of 90% during exercise.

Answer

SpO2 that drops to 88% only during sleep for more than 10% of the night.

Question 2

A patient with COPD is admitted with an acute exacerbation and is noted to be a CO2 retainer. The physician orders oxygen to maintain a specific, controlled saturation level and wants to deliver a precise fraction of inspired oxygen (FiO2) of 28%. Which of the following oxygen delivery devices is most appropriate for this patient?

Accepted Answer

Venturi (air-entrainment) mask

Answer

Nasal cannula at 6 L/min

Answer

Simple face mask at 5 L/min

Answer

Non-rebreather mask at 15 L/min

Question 3

A COPD educator is providing critical safety instructions to a patient and their family before the delivery of home oxygen equipment. Which of the following points is the MOST important to emphasize to prevent a fire-related accident?

Accepted Answer

Strictly prohibit smoking and keep oxygen at least 10 feet away from any open flame or heat source.

Answer

Store oxygen cylinders upright in a well-ventilated space.

Answer

Use water-based lubricants for dry nares instead of petroleum-based products.

Answer

Ensure the oxygen tubing does not exceed 50 feet to prevent falls.

Question 4

A patient using portable compressed oxygen cylinders for ambulation complains that the tanks run out too quickly, limiting their time away from home. Which of the following devices is specifically designed to deliver oxygen more efficiently and extend the duration of a portable oxygen supply?

Accepted Answer

An oxygen-conserving device (OCD)

Answer

A high-flow nasal cannula

Answer

An oxygen concentrator

Answer

A liquid oxygen system

Question 5

A COPD educator needs to calculate the approximate duration of a portable E-cylinder for a patient. The tank pressure gauge reads 1800 psi, the prescribed flow rate is 3 L/min, and the tank factor for an E-cylinder is 0.28. How many minutes will the oxygen supply last?

Accepted Answer

168 minutes

Answer

280 minutes

Answer

1920 minutes

Answer

504 minutes

Question 6

Which of the following oxygen systems is generally preferred for a highly active COPD patient who requires continuous oxygen at a high flow rate (e.g., 4-5 L/min) and prioritizes longer duration and lighter carrying weight for extended periods away from home?

Accepted Answer

A portable liquid oxygen system

Answer

A portable oxygen concentrator (POC)

Answer

A compressed gas E-cylinder with an oxygen-conserving device

Answer

A stationary oxygen concentrator with 50-foot tubing
