Answer to Question 1

A
Feedback:
Sampling involves selecting a portion of the population to represent the population. A low power to detect a difference in the outcomes of the two group results from a sample size that is too small. The other answers are not effects of having a sample size that is too small.

Answer to Question 2

A, C, D
Feedback:
Nurse researchers have used biophysiologic measures for a wide variety of purposes, and these measures have many advantages. They are relatively accurate and precise, objective, not easily distorted by patients, and valid. However, they cannot effectively measure subjective experiences such as pain and fatigue; a visual analog scale would be more appropriate for that.
