A nursing student asked the respiratory floor nurse why the adventitious wheezing breath sounds are present in asthmatic patients. The nurse should respond:

this is an abnormal breath sound due to bronchial airways being narrowed, bronchoconstriction

this is a normal breath sound due to normal gas exchanged

this is an abnormal breath sound due to bronchial airways being dilated, bronchodilation

this is a normal breath sound due to the alveoli being fluid-filled
