Question 1 of 5
Rales and rhonchi are frequently noted during an examination of lung sounds. What is the difference between the two?
Correct Answer: C
Rationale: The correct answer is that rales occur on inspiration, while rhonchi occur on expiration. Rales are typically heard during inhalation when there is fluid in the alveoli or air passages. Rhonchi, on the other hand, are caused by air passing through obstructed airways during exhalation due to secretions in the respiratory tract.
Choice A is incorrect because the loudness of the sounds is not the primary distinguishing factor between rales and rhonchi.
Choice B is incorrect as rhonchi can be heard in individuals beyond infancy.
Choice D is incorrect as rales can be present in patients of various age groups, not just infants.
