During auscultation of the lungs, the nurse knows that decreased breath sounds would most likely be heard:
1.
when the bronchial tree is obstructed.
2.
when adventitious sounds are present.
3.
in conjunction with whispered pectoriloquy.
4.
in conditions of consolidation, such as pneumonia.
The correct answer is:
1. When the bronchial tree is obstructed.
Explanation: Decreased breath sounds are most commonly heard when there is an obstruction in the bronchial tree, such as in cases of asthma, bronchitis, or a foreign body blocking the airways, which can reduce airflow and the ability to hear normal breath sounds.
