Answer to Question 1

D
Feedback:
The norms of some lab values change somewhat with age. An abnormality in a younger person may be normal for an older person or vice versa. Not all lab values require fasting. Laboratory values of older clients have the potential to be volatile and unstable.

Answer to Question 2

B
Feedback:
The suffix -centesis denotes that a structure was punctured.
