therapy?
A. Respiratory rate 32/min
B. PaO2 90 mm Hg
C. Fraction of inspired oxygen (FiO2) 65% for 4 days
D. Oxygen saturation (SaO2) 90%
Answer: D. Oxygen saturation (SaO2) 90%
Question: 4 of 11
A nurse is caring for a critically ill client who has COPD and requires delivery of a precise
concentration of oxygen. Which of the following types of oxygen-delivery devices is
indicated for this client?
A. Simple face mask
B. Nasal cannula

Question: 5 of 11

mask. The nurse should emphasize that the client must
A. clean the mask with soapy water once every other day.
B. reposition the elastic band frequently.
C. apply petroleum jelly around and inside the nares.

Question: 6 of 11
A nurse is caring for a client who has a tracheostomy. Which of the following pieces of
equipment should the nurse use when administering oxygen to this client?
A. Distilled water for humidification
B. A tracheostomy collar
C. A nasal cannula
D. An aerosol mask
Answer: B. A tracheostomy collar
Question: 7 of 11
A nurse is providing discharge teaching with a client who is going home on continuous liquid
oxygen therapy. Which of the following instructions should the nurse include?
A. “Place the oxygen tank in a clutter-free environment.”
Correct:
The nurse should instruct the client to place the oxygen-delivery system in a clutter-free
environment that is well ventilated. This prevents injuries from improper placement of the
oxygen equipment.
Incorrect:
B. “Keep the oxygen tank at least 6 feet away from a heat source.”
The nurse should instruct the client to keep the oxygen tank at least 10 feet away from heat
sources, such as open flames (candles, fireplaces, stoves), because oxygen supports
combustion. This means that even small sparks or heat can cause a fire to ignite more easily
and burn more intensely in the presence of oxygen. Keeping the tank at a safe distance helps
reduce the risk of accidental fires and ensures the client’s safety while using oxygen therapy.
Additionally, the nurse should educate the client on the importance of not smoking near
oxygen equipment and ensuring proper ventilation in the area where oxygen is used.
Always prioritize safety when using oxygen to minimize potential hazards.

adverse effect of oxygen therapy?
A. Poor skin turgor
B. Copious respiratory secretions
C. Cracks in the oral mucosa
D. Elevated heart rate
Answer: C. Cracks in the oral mucosa
Question: 9 of 11
A nurse is caring for a client who has been receiving oxygen via nasal cannula for 4 hr.
Which of the following assessment findings helps indicate that oxygen therapy has been
effective?
A. Respiratory rate 14/min

C. Cardiac output 5.6 L/min
D. PaCO2 68 mm Hg
Answer: A. Respiratory rate 14/min
