to listen with a stethoscope to heart and lung sounds

Question 9

percussion

Answer 9

examination method of tapping on the body to elicit vibrations and sounds to estimate the size, border, or fluid content of a cavity, such as the chest

Question 10

lung biopsy (Bx)

Answer 10

removal of a small piece of lung tissue for pathologic examination

Question 11

lung scan; ventilation-perfusion (V/Q) scan

Answer 11

a two-part nuclear scan of the lungs to detect abnormalities of ventilation or perfusion (blood flow)

Question 12
