The nurse is assessing the respiratory system of a newborn. Which anatomic differences place the infant at risk for respiratory compromise? (Select All that Apply.)
The nasal passages are narrower.
The tongue is smaller.
There are significantly fewer alveoli.
The larynx is more funnel shaped.
The trachea and chest wall are less compliant.
Correct Answer : A,C,D,E
A. Narrower nasal passages can lead to increased airway resistance and difficulty in breathing, as infants are primarily nasal breathers.
B. A smaller tongue does not directly contribute to respiratory compromise; however, it can pose a risk for airway obstruction if the tongue falls back against the oropharynx.
C. Significantly fewer alveoli mean less surface area for gas exchange, which can impair oxygenation and carbon dioxide elimination.
D. A more funnel-shaped larynx can predispose infants to upper airway obstruction and increase the work of breathing.
E. Less compliant trachea and chest wall make it harder for the infant to expand the lungs, leading to increased work of breathing and potential respiratory distress.
