When assessing the respiration of a client, a nurse observes a hissing, crowing sound. Based on this information, the nurse recognizes that which is the possible cause of this sound?
A) Spasms and edema of the bronchi
B) Air passing through secretions present in the air passages
C) Obstruction near the glottis
D) Air passageway being partially blocked
C
Feedback:
Obstruction near the glottis causes a hissing, crowing sound. Spasms and edema of the bronchi do not cause a hissing, crowing sound; they cause asthma, a condition that causes difficulty breathing. Air passing through secretions present in the air passages causes stertorous breathing, but does not cause a hissing, crowing sound. Partially blocked air passageway causes snoring, which is not a hissing, crowing sound. Snoring is common during sleep, when the person's tongue falls back as a result of relaxation.
