Answer to Question 1
A
Feedback:
If there is a normal mixture of oxygen and other gases in the environment, the oxygen analyzer will indicate 0.21 (21). An oxygen analyzer is a device that measures the percentage of delivered oxygen to determine whether the client is receiving the amount prescribed by the physician. The nurse or respiratory therapist first checks the percentage of oxygen in the room air with the analyzer. If there is a normal mixture of oxygen and other gases in the environment, the analyzer indicates 0.21 (21). When the analyzer is positioned near or within the device used to deliver oxygen, the reading should register at the prescribed amount (>0.21).

Feedback:
The client's assessment of pain, based on a pain rating, is the most appropriate assessment data. The pain is rated on a 1 to 10 scale and nursing actions are then implemented to reduce the pain. The nurse's impression of pain and nonverbal clues are subjective data. Pain relief after nursing intervention is appropriate, but is a part of evaluation.
