Which is NOT a sign of respiratory problems?

Question

Quizplus · Accepted Answer

Making barely audible breath sounds could be a sign of normal breathing or respiratory problems, so it cannot be conclusively attributed to respiratory problems. The other options are signs of respiratory problems. The soft tissues of the chest retracting with each breath indicates a struggle to breathe, holding the mouth open while breathing suggests difficulty with breathing through the nose, and spreading the nostrils suggests a struggle to inhale enough air through the nose.
