Final answer:
In a person with congestive heart failure, the type of breath sound that is more likely to be heard is crackles. These sounds are caused by the presence of fluid in the lungs—a common symptom of congestive heart failure due to fluid overload and pulmonary congestion.
Step-by-step explanation:
In the context of congestive heart failure, the type of breath sound that is more likely to be heard is crackles. Crackles are caused by the sudden opening of small airways and alveoli collapsed by fluid or exudate, or the movement of fluid within the airways during a breath. They are often associated with the presence of fluid in the lungs, which is a common symptom in congestive heart failure due to the heart's inability to pump blood effectively, leading to fluid overload and pulmonary congestion.
In contrast, rhonchi are more typical of airway obstruction caused by secretions and are often heard in conditions like chronic bronchitis. Decreased or absent breath sounds may be present in conditions like pneumothorax or pleural effusion, where air or fluid interferes with the transmission of sound. Stridor is a high-pitched, wheezing sound most commonly associated with upper respiratory obstructions and is not characteristic of congestive heart failure.
