A patient arrives on the nursing unit because of a sudden onset of dyspnea. Which assessment
data would the nurse expect to find?
1 A respiratory rate of 24 breaths/min
2 Cyanosis
3 Clubbing of the fingers
4 A regular breathing pattern - CORRECT ANSWERS 1
Rationale: A respiratory rate of 24 breaths/min could be seen in a dyspneic patient. All of the
other options would be seen when hypoxia has been present for a long period of time.
A patient with an oxygen mask with a reservoir bag is seen while making initial rounds. Which
problem might the patient experience if the reservoir bag becomes deflated?
1 Elevated oxygen levels
2 Elevated carbon dioxide levels
3 Drying of the nasal mucous membranes
4 Decrease in the number of respirations - CORRECT ANSWERS 2
Rationale: If the reservoir is deflated, the patient can breathe large amounts of carbon dioxide.
You are preparing to observe a patient with COPD perform incentive spirometry exercises. With
which of the following steps is the patient likely to have difficulty?
1 Placing the mouthpiece correctly
2 Being able to hold breath for 3 seconds after inhalation

3 Being able to blow quickly into the device
4 Performing incentive spirometry three times for each reading - CORRECT ANSWERS 2
Rationale: A patient with COPD often has difficulty holding the breath at the end of inhalation.
There is no reason the patient would not be able to hold the mouthpiece. Patients do not blow
into an incentive spirometer. Three readings are made with a peak flow meter.
Humidification is added to a nasal cannula when the flow is set at:
1 1 L/min.
2 2 L/min.
3 3 L/min.
4 4 L/min. - CORRECT ANSWERS 4
Rationale: When the oxygen rate is 4 L/min or greater, humidifica- tion is needed to prevent
drying of the nasal mucous membrane. Under 4 L the moisture can be provided by the nasal
passages.
A patient needs an FiO2 of 80%. Which of these oxygen delivery devices can deliver oxygen at
this FiO2 level? (Select all that apply.)
1 Nasal cannula at 6 L/min
2 Venturi mask at 12 L/min
3 Nonrebreathing mask at 6 L/min
4 Partial rebreathing mask at 6 L/min - CORRECT ANSWERS 2
