During auscultation of the lungs, the nurse expects decreased breath sounds to be heard in which situation?
When adventitious sounds are present
When the bronchial tree is obstructed
In conjunction with whispered pectoriloquy
In conditions of consolidation, such as pneumonia
The Correct Answer is B
A. Adventitious sounds (e.g., wheezing, crackles, or stridor) are abnormal sounds that may be heard in addition to breath sounds. They do not specifically correlate with decreased breath sounds.
B. When there is obstruction in the bronchial tree (such as in conditions like asthma, chronic obstructive pulmonary disease (COPD), or a foreign body obstruction), the airflow is reduced, leading to decreased breath sounds in the affected areas.
C. Whispered pectoriloquy refers to hearing whispered sounds through the stethoscope, which would be more clearly heard with consolidation or lung tissue becoming more solid (e.g., in pneumonia), not with decreased breath sounds.
D. In consolidation (such as pneumonia), breath sounds are typically increased or bronchial, not decreased. The consolidation makes the lung tissue more solid, which can amplify breath sounds.

Correct Answer is B
Explanation
A. Increased tactile fremitus and dull percussion tones would suggest consolidation or pathology, which is not normal.
B. Muffled voice sounds and symmetric tactile fremitus are normal findings in healthy lung tissue.
C. Adventitious sounds and limited chest expansion would indicate pathology such as pneumonia or other lung diseases.
D. Absent voice sounds and hyper resonant percussion tones would be indicative of a pneumothorax or emphysema, not normal lung findings.
