A nurse auscultates rhonchi when assessing a patient's lungs. This lung sound can be differentiated from crackles (rales) in that rhonchi
1. frequently occur during inspiration.
2. may clear after coughing.
3. are usually associated with fluid or secretions in small airways or alveoli.
4. have a musical quality tone.
Correct
2
Rationale: Rhonchi are course bubbly sounds that frequently occur during expiration and are heard over the larger airways. Rhonchi are associated with fluid or secretions in the larger airways and may clear after a strong cough as a result of movement of the secretions. Crackles (rales) are discrete popping sounds frequently heard during inspiration and are often caused by fluid or secretions in the smaller airways or alveoli. Wheezes are caused by narrowed air passages and have a musical quality.
