Passage / Scenario
An infant with a history of recurrent respiratory infections.The mother of an infant who has been treated for recurrent respiratory infections asks the nurse why infants are at increased risk for respiratory infections. What is the best response by the nurse?
Correct answer
C
Rationale
The correct answer is C. Infants have narrower airways, making them more prone to obstruction and trapping of organisms, leading to increased risk of respiratory infections. This physiological difference makes it easier for pathogens to become trapped and cause infection. Choice A is incorrect as it does not address the anatomical differences in infants' airways. Choice B is incorrect because the question does not focus on the size of the airways, but rather on their narrowness. Choice D is incorrect as infants' faster respiratory rates do not directly contribute to increased risk of respiratory infections.
