Administering oxygen therapy with a nonrebreather mask has which of the following advantages?
A. Offers the highest oxygen concentration of the
... [Show More] low-flow systems
B. Provides oxygen concentrations of 40% to 60%
C. Incorporates a design that requires minimal monitoring of the client
D. Is designed for safety once the mask's valves and flaps are sealed
A. Offers the highest oxygen concentration of the low-flow systems
A nonrebreather mask delivers oxygen concentrations of 60% to 80%. Thus, it provides a higher fraction of inspired oxygen (FiO2) than other low-flow systems such as nasal cannula (delivering about 24% to 44%) or a simple mask (delivering 40% to 60%)
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
B. A tracheostomy collar
A tracheostomy collar is a piece of equipment that fits over the tracheostomy site and is held in place by an adjustable elastic strap that fits around the client's neck. The collar provides the client with the prescribed oxygen concentration while also providing high humidity
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
B. SaO2 90%
C. Cardiac output 5.6 L/min
D. PaCO2 68 mm Hg
A. Respiratory rate 14/min
The expected reference range for respirations is 12 to 20/min. Stabilization of the respiratory rate, especially if the client was previously tachypneic, is an indication that oxygen therapy is effective
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."
B. "Keep the oxygen tank at least 6 feet away from a heat source."
C. "Ensure you are close to electricity to use your oxygen tank."
D. "Turn the valve on the oxygen tank until an alarm sounds."
A. "Place the oxygen tank in a clutter-free environment."
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
B is incorrect because the nurse should instruct the client to keep the oxygen tank at least 10 feet from a heat source (such as an open flame candle or fireplace) because oxygen can ignite as ar result of the heat, causing a fire
A nurse is providing discharge teaching to a client who will continue oxygen therapy at home. The nurse should instruct the client that turning the knob on the oxygen flow meter all the way to the right...
A. starts the flow of oxygen
B. Provides the maximal oxygen flow
C. Provides a minimal oxygen flow
D. Stops the flow of oxygen
D. Stops the flow of oxygen
Turning the knob on the flow meter all the way to the right allows no oxygen to flow from the oxygen cylinder to the client... or in layman's terms "righty tighty, lefty loose'y"
A nurse is caring for a client who was admitted with community-acquired pneumonia and has been receiving oxygen therapy for several days. Which of the following findings indicates an adverse effect of oxygen therapy?
A. Poor skin turgor
B. Copious respiratory secretions
C. Cracks in the oral mucosa
D. Elevated heart rate
C. Cracks in the oral mucosa
Oxygen, especially when delivered long-term and without sufficient humidification, has a drying effect that can cause cracks in the nasal and oral mucosa.
A home health nurse is teaching a client who has just started receiving oxygen therapy via 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.
D. Make sure there is adequate condensation in the tubing.
B. Reposition the elastic band frequently.
Tubing and elastic bands that are part of oxygen-delivery devices can cause pressure not he skin that can lead to breakdown. Padding them and frequently changing their position can help prevent this complication.
Oxygen therapy is prescribed for a client who is brought to an emergency department in the early stages of hypoxia. When assessing this client, a nurse should expect which of the following findings?
A. Elevated blood pressure
B. Decreased respiratory rate
C. Cyanosis
D. Peripheral edema
A. Elevated blood pressure
During the early stages of hypoxia, blood pressure is usually elevated (unless shock is the cause of the client's hypoxia). In the late stages of hypoxia, clients are likely to develop hypotension
A nurse is caring for a client who has dyspnea, slight cyanosis, and a respiratory rate of 28/min. During which of the following phases of the nursing process will the nurse determine that the client has impaired gas exchange?
A. Assessment
B. Diagnosis
C. Planning
D. Evaluation
B. Diagnosis
During the diagnosis phase, the nurse analyzes and interprets data gathered from the nursing assessment to formulate a nursing diagnosis, which in this case is impaired gas exchange
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
C. Venturi mask
D. Face tent
C. Venturi mask
A Venturi mask is most often used for critically ill clients who require administration of a specific concentration of oxygen. This is the most accurate form of oxygen delivery and keeps carbon dioxide buildup minimal
A nurse should recognize that which of the following findings is an indication for oxygen therapy?
A. Respiratory rate 32/min
B. PaO2 90mm Hg
C. Fraction of inspired oxygen (FiO2) 65% for 4 days
D. Oxygen saturation (SaO2) 90%
D. Oxygen saturation (SaO2) 90%
Oxygen therapy is indicated for clients who are at risk for or have developed hypoxia. In the early stages of hypoxia, the heart rate increases and the arterial oxygen saturation (SaO2) falls below 94%
A 57-year-old client with a 30-pack-year smoking history has recently received confirmation of a possible malignant tumor in the lower lobe of his right lung. He is scheduled for a tumor resection and a lower-lobe lobectomy in the morning. This client was also diagnosed a year ago with mild chronic bronchitis, but has never used oxygen therapy. (Lifetime smoking exposure is expressing in pack years. With 20 cigarettes in a pack, multiply the number of packs smoked per day by the number of years of smoking to determine the pack year. This client smoked one pack a day for 30 years, hence his 30 pack-year history).
Which of the following statements should you make to the client to describe the effects of the planned surgery not he client's oxygen demand?
A. You will be short of breath for the rest of your life and will need to greatly decrease your daily activities.
B. Your left lung will compensate after the surgery and you will breathe much easier.
C. "Removing a section of your right lung will decrease the oxygen your body receives, but we can provide extra oxygen if you need it."
C. "Removing a section of your right lung will decrease the oxygen your body receives, but we can provide extra oxygen if you need it."
This statement both identifies and discusses the appropriate intervention for a situation that is likely to affect the client's oxygen demand.

Which of the following statements indicates that the client understands how to identify when he needs supplemental oxygen therapy?
A. "When I feel anxious and have to work at breathing, I will know I need oxygen."
B. "I will use my oxygen when I know I'll be walking for any long distances."
C. "When I can't sleep at night, I'll put on my oxygen."
A. "When I feel anxious and have to work at breathing, I will know I need oxygen."
