Answer to Question 1

ANS: B
To determine if an individual will tolerate lung resection surgery, reports of activity tolerance and pulmonary function testing are used. Although no one pulmonary function study or absolute cut-off has proven ideal, the FEV1 and diffusing capacity for carbon monoxide (DLCO) are the most frequently used measures.

Answer to Question 2

ANS: B
One of the major factors that determines the prognosis of lung cancer and guides the proper se-lection of treatment is the extent to which the cancer has spread in the lungs and throughout the body.
