OXYGEN THERAPY AND RESPIRATORY CARE
EXAM Q & A
1) The nurse is administering oxygen to clients in the PACU. What is the most
important safety issue related to oxygen that the nurse should consider?
A) Oxygen allows common flammable materials to burn faster and hotter.
B) Oxygen should be given to all clients postoperatively to prevent nosocomial
infections.
C) Oxygen can increase the heart's work of pumping blood.
D) Decreased oxygen concentration weakens the stimulus to breathe.
2) The nurse is explaining to a client with cystic fibrosis the goals of the oxygen
therapy prescribed for her. Which of the following is a therapeutic effect of oxygen
administration?
A) It reverses high and low oxygen concentrations in the blood.
B) It increases the work of the respiratory system, allowing it to work more efficiently.
C) It decreases the heart's work in pumping blood and eases the heart's load.
D) It affects ventilatory drive control mechanisms and increases the stimulus to breathe.
3) The nurse administering oxygen to clients with respiratory disorders is careful to
monitor concentrations to prevent oxygen toxicity. How does this adverse reaction
manifest itself?
A) Changes in heart rate
