A normal, healthy 35-year-old male client visits the doctor’s office for a routine annual physical. When auscultating between the first and second interspaces on the anterior chest, the nurse anticipates which type of breath sound?

Number 1 is correct.

Rationale: Located between the first and second interspaces in the anterior chest are bronchovesicular sounds. Normally heard throughout the lung fields are vesicular sounds. Located between the second and third intercostal spaces of the anterior chest are bronchial sounds. Heard over the trachea are tracheal breath sounds.
