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.

Correct Answer is D
Explanation
A. Uses thumb and index fingers in a pincer grasp: The pincer grasp typically develops around 9 to 12 months of age, not at 6 months.
B. Sitting steadily without support: Most infants begin to sit steadily without support between 6 and 8 months of age, so this would be considered a developmental milestone for a 6-month-old.
C. Closed posterior fontanel: The posterior fontanel typically closes by 2 months of age. By 6 months, the posterior fontanel should be closed, so this finding would not be expected.
D. Lateral incisors: By 6 months of age, most infants will have erupted their lower central
incisors. The eruption of the lateral incisors typically occurs around 9 to 13 months of age, so this would be a normal finding for a 6-month-old infant.
Correct Answer is C
Explanation
A. Transduction - Transduction refers to the process of reasoning from one specific instance to another without necessarily understanding the broader concept. The girl's statement about the sky and her throat does not demonstrate this mental process.
B. Centration - Centration involves focusing on only one aspect of a situation while ignoring others. The girl's statement may involve a degree of focus, but it's more indicative of a broader imaginative process.
C. Magical thinking - Magical thinking involves attributing human emotions or characteristics to inanimate objects or natural phenomena. The girl's belief that the sky is crying because it's sad about her throat hurting reflects this type of thinking.
D. Animism - Animism is a belief system that attributes life or consciousness to natural objects or phenomena. While the girl's statement involves anthropomorphizing the sky, it specifically
involves emotions rather than attributing life itself to the sky. Therefore, magical thinking is a more accurate description.
