The nurse is listening to the patient's lungs. Which information should the nurse use to document normal patient lung sounds?
a. Rales in the right lower lobe
b. No adventitious breath sounds
c. Pleural friction rub in the left lung
d. Inspiratory wheezing in the upper lobes
B
A clinical indicator of normal lung sounds is a lack of adventitious breath sounds, meaning that the patient does not exhibit crackles, rhonchi, rubs, stridor, or wheezing. Rales are the same as crackles and indicate fluid or atelectasis in the alveoli. Pleural friction rubs are not normal and indicate inflammation of the pleural lining. Wheezing indicates constriction of the airway as heard during an asthma attack.
