MULTIPLE CHOICE

 

1. The most detrimental effect of breathing a high concentration of oxygen is development of oxygen:

a.	tolerance.
b.	dependence.
c.	toxicity.
d.	saturation.

 

ANS:   C

The most detrimental effect of breathing a high concentration of oxygen is the development of oxygen toxicity. It can occur in any patient breathing oxygen concentrations of higher than 50% for more than 24 hours. Patients most likely to develop oxygen toxicity are those who require intubation, mechanical ventilation, and delivery of high oxygen concentrations for extended periods.

2. As a result of receiving oxygen in higher than normal concentrations, patients with chronic obstructive pulmonary disease may develop:

a.	air trapping.
b.	carbon dioxide retention.
c.	air hunger.
d.	respiratory alkalosis.

 

ANS:   B

In patients with severe chronic obstructive pulmonary disease, carbon dioxide retention may occur as a result of administration of oxygen in higher concentrations.

3. Which of the following arterial blood gas values would indicate a need for oxygen therapy?

a.	PaO2 80 mm Hg
b.	PaCO2 35 mm Hg
c.	HCO3– 24 mEq
d.	SaO2 87%

 

ANS:   D

The amount of oxygen administered depends on the pathophysiological mechanisms affecting the patient’s oxygenation status. In most cases the amount required should provide an arterial partial pressure of oxygen (PaO₂) of greater than 60 mm Hg or an arterial hemoglobin saturation (SaO₂) of greater than 90% during both rest and exercise.

4. Which of the following oxygen administration devices delivers the highest concentration of oxygen?

a.	Non-rebreathing mask
b.	Nasal cannula
c.	Partial rebreathing mask
d.	Simple mask

 

ANS:   A

A non-rebreathing mask with a tight seal over the face can deliver 55% to 70% oxygen.

5. The most accurate and reliable control of FIO₂ can be achieved through the use of a:

a.	simple mask.
b.	non-rebreathing circuit (closed).
c.	air-entrainment mask.
d.	non-rebreathing mask.

 

ANS:   B

The most reliable and accurate means of delivering a prescribed concentration of oxygen is through the use of a non-rebreathing circuit (closed).
