Answer to Question 1

D
Feedback:
When administering oxygen to a critically ill client using a nonrebreather mask, the nurse should remember that an oxygen concentration of more than 50 given for longer than 48 hours can cause oxygen toxicity in the client. Oxygen toxicity means lung damage that develops when oxygen concentrations of more than 50 are administered for longer than 48 to 72 hours. The best way to prevent oxygen toxicity is to administer the lowest FiO2 possible for the shortest amount of time.

Answer to Question 2

A
Feedback:
A nurse who is cross-trained is able to assume non-nursing jobs, depending on the census or levels of client acuity on any given day. This does not necessarily guarantee changes to work scheduling or earlier retirement. Cross-training does not address the orientation of new employees or students.
