The nurse is assessing a 4-month-old boy during a scheduled visit. Which findings might suggest a developmental problem?
The child does not vocally respond to voices.
The child never squeals or yells.
The child does not babble.
The child does not say dada or mama.
The Correct Answer is C
A. The child does not vocally respond to voices: While vocal responsiveness is an important aspect of development, it may vary among infants and is not necessarily indicative of a developmental problem at 4 months.
B. The child never squeals or yells: Squealing and yelling are vocalizations that infants may or may not exhibit at this age, and their absence alone may not necessarily indicate a developmental problem.
C. The child does not babblE. Babbling, which typically begins around 4 to 6 months of age, involves the repetition of consonant-vowel combinations (e.g., "bababa"). The absence of babbling by 4 months may suggest a delay in language development and could be a potential sign of a developmental problem.
D. The child does not say dada or mamA. Infants may begin to associate "dada" or "mama" with specific caregivers, but this typically occurs later, closer to 6 to 9 months of age. The absence of this behavior at 4 months may not necessarily indicate a developmental problem.

Correct Answer is C
Explanation
A. Height in girls increases rapidly after menarche and usually ceases immediately after
menarchE. Height increases during adolescence are not directly related to menarche. Growth in girls typically continues for several years after menarche, although at a slower rate compared to the pre-pubertal growth spurt.
B. Boys' growth spurts usually begin between the ages of 8 and 14 years and end between the ages of 13½ and 17½ years: While boys do experience a growth spurt during adolescence, the timing and duration of growth spurts can vary widely among individuals. Growth typically
continues beyond the age of 14, with some boys reaching their full adult height in their late teens or early twenties.
C. Peak height velocity (PHV) occurs at approximately 12 years of age in girls or about 6 to 12 months after menarchE. Peak height velocity refers to the period of most rapid growth during adolescence. In girls, PHV typically occurs around the age of 12, with growth continuing for some time after menarche.
D. Boys reach PHV and peak weight velocity (PWV) at about 16 years of agE. Boys generally experience PHV and PWV later than girls, typically occurring around the age of 14 to 16. These milestones mark the period of most rapid growth in boys, with height and weight increasing significantly during this time.
Correct Answer is B
Explanation
A. At 3 months, infants are not expected to have the fine motor skills necessary to pick up objects with their fingers.
B. By 3 months, infants should be able to lift their head and chest during tummy time, and the inability to do so could indicate developmental delays or other health issues.
C. Infants typically cannot sit without support until they are around 6 months old.
D. The ability to bring objects to the mouth develops around 4 months of age, so it is not expected for a 3-month-old infant to do this consistently.
