A client with a history of COPD is being assessed. When the nurse percusses the client's chest, which characteristic sound is expected?
Tympany
Hyperresonance
Resonance
Dullness
The Correct Answer is B
Choice a reason:
Tympany is a drum-like, resonant sound that is typically heard over air-filled structures, such as the gastric bubble, not the chest. It is not a sound associated with the lungs, especially in the context of COPD.
Choice b reason:
Hyperresonance is an abnormally loud, lower-pitched sound than normal resonance heard over hyperinflated areas of the lung, such as in cases of COPD. This is due to the increased air content within the lungs, often because of overdistension or destruction of alveolar tissue, as seen in emphysema, a common type of COPD.
Choice c reason:
Resonance is the normal sound heard over healthy lung tissue when percussed. However, in the case of COPD, particularly emphysema, the destruction of lung tissue leads to hyperinflation and thus a hyperresonant sound rather than the normal resonance.
Choice d reason:
Dullness is heard when fluid or solid tissue replaces air in the lung or occupies the pleural space, as in the case of pneumonia or pleural effusion. This is not characteristic of COPD, where there is an increase in air due to the breakdown of alveolar walls.

Correct Answer is A
Explanation
Choice A Reason:
This approach is recommended as it allows for a systematic comparison between the two sides of the chest. Percussion should start at the apices of the lungs, which are located just above the clavicles, and proceed downwards. This method ensures that any differences in percussion note, which could indicate underlying pathology, are identified by direct comparison.
Choice B Reason:
While this approach also involves a systematic assessment, it does not allow for immediate comparison between the two sides of the chest. It is important to compare corresponding areas on each side as you go to detect any asymmetry or changes in resonance.
Choice C Reason:
This method, similar to choice B, does not facilitate immediate side-to-side comparison during the assessment. Immediate comparison is crucial for identifying subtle differences that may indicate conditions such as pleural effusion or pneumothorax.
Choice D Reason:
Starting the percussion above the left clavicle and moving to the right chest after completing the left side does not allow for direct comparison of symmetrical chest areas. Additionally, assessing the right chest moving upward from the liver is not a standard practice, as the liver dullness can interfere with the percussion of the lower right lung fields.
Correct Answer is D
Explanation
Choice a reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. Bronchovesicular sounds do not involve the change of vowel sounds during auscultation.
Choice b reason:
Bronchophony is the term used when the voice sounds are more clear and louder over the chest wall, usually indicating lung consolidation. However, it does not specifically refer to the change of vowel sounds from "ee" to "ay."
Choice c reason:
Normal voice resonance is when voice sounds heard through auscultation are muffled and indistinct. It does not involve a clear change in vowel sounds, which is what occurs with egophony.
Choice d reason:
Egophony is characterized by the change of the "ee" vowel sound to a nasal "ay" or "a" sound when auscultating the lungs. This phenomenon typically suggests lung consolidation, as might be seen with pneumonia.
