NUR 208 Oxygen Therapy ATI Post Test – Study Guide, Practice Questions &
Nursing Review
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 - ANS ✔✔B. Reposition the elastic
band frequently
Tubing and elastic bands that are part of oxygen-delivery devices can cause pressure on the skin
that can lead to a 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 ER 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 - ANS ✔✔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.
, Administering oxygen therapy with a nonrebreather mask has which of the following
advantages?
A. offers the highest oxygen concentration of the low-flow systems
B. Provides oxygen concentration of 40% to 60%.
C. Incorporates a design that requires minimal monitoring of the client
D. Is designed for safety once the masks valves and flaps are sealed. - ANS ✔✔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 a nasal cannula
(delivering about 24% to 44%) or a simple mask (delivering 40-60%).
A nurse should recognize that which of the following findings is an indication for oxygen
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% - ANS ✔✔D. Oxygen saturation (SaO2) 90%
A nurse is caring for a critically ill client who has COPD and requireds 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
