The auscultation of bronchophony, egophony, and whispered pectoriloquy provides useful information to determine if the lungs are filled with air or fluid. Which guideline is recommended for examining these voice sounds?
a. Only one of the three techniques needs to be performed, because they all provide the same information.
b. All of the techniques need to be included in a comprehensive examination if tactile fremitus has been performed.
c. All three techniques should be performed if an abnormality is detected during the general auscultation, percussion, or palpation.
d. Two of the three techniques should be performed if an abnormality is detected during the general auscultation, percussion, or palpation.
A
The examination of voice sounds will reveal whether the lungs are filled with air, fluid, or are solid. This auscultation needs to be performed only if an abnormality is detected during the general auscultation, percussion, or palpation. There are three techniques by which voice sounds can be examined: bronchophony, egophony, and whispered pectoriloquy. Only one of these examinations needs to be performed because they are all variations of the same physical principle and examination technique, and they all provide the same information. The voice sound findings will parallel those obtained during tactile fremitus.
