Answer to Question 1

B

Feedback
A The sensor should be placed on an extremity site (such as an earlobe or digit) with adequate local circulation, and the site should be free of moisture. The sensor should not be positioned on the arm.
B Peripheral vascular disease can reduce pulse volume, which may affect the pulse oximetry reading.
C Reduced light in the room will not affect the oximetry reading. Outside light sources can interfere with the oximeter's ability to process reflected light.
D An increased temperature of the room will not affect the oximetry reading. If the room were very cold, the patient's peripheral blood flow might decrease, affecting the oximetry reading.

Answer to Question 2

C
Chronic pain disorders, irritable bowel syndrome, somatization disorder, and clinical depression have all been linked to chronic stress.
A client's avoiding discussion of the problem may not be related to chronic stress.
The client's negative comments about his or her colleagues may not be related to chronic stress.
The client's blaming of the boss may not be related to chronic stress.
