Answer to Question 1

ANS: B
If there is still no visible mist output, the clinician should inspect the couplant chamber to confirm proper fill level and the absence of any visible dirt or debris.

Answer to Question 2

ANS: A
To minimize problems in this area, all clinicians should strictly follow CDC standards and air-borne precautions, including those specified for control of exposure to tuberculosis.
