Answer to Question 1

B
Feedback:
An advantage of biophysiologic measures is that patients cannot distort the measurements and they include objective measures. Biophysiologic measures include both in vivo and in vitro measures. Biophysiologic measures are accurate, precise, and objective. They are not self-reported and cannot effectively indicate pain levels.
