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.

Answer and Explanation

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 B

Explanation

A. At 6 years, children are expected to have mastered the ability to descend stairs without needing to place both feet on each step or hold onto the railing.

B. By 3 years of age, children typically begin to walk up stairs using a reciprocal pattern, placing only one foot on each step, but may still require a railing for support when going down.

C. At 4 years, children should be able to go both up and down stairs using a reciprocal pattern and without the need for a rail.

D. By 5 years, the expectation is that children can confidently navigate stairs in a manner similar to adults, without placing both feet on each step or requiring railing support.

A. Myelination of the brain and spinal cord is complete at about 24 months. B. Alveoli reach adult numbers by 3 years of age. C. Urine output in a toddler typically averages approximately 30 mL/hour. D. Toddlers typically have strong abdominal muscles by the age of 2.

Correct Answer is A

Explanation

A. Myelination of the brain and spinal cord is a continuous process that begins during fetal development and continues through childhood and adolescence. While significant myelination

occurs during infancy and toddlerhood, it is not complete by 24 months. However, substantial progress in myelination does occur during the toddler years, contributing to the development of motor and cognitive skills.

B. Alveoli reach adult numbers by 3 years of age. This statement is incorrect. Alveoli continue to develop and increase in number after birth, reaching adult numbers around adolescence, not by 3 years of age.

C. Urine output in a toddler typically averages approximately 30 mL/hour. This statement is incorrect. Toddlers typically have higher urine output rates than adults due to their smaller

bladder capacity and higher metabolic rate. The average urine output for a toddler is around 1-2 mL/kg/hour, which varies depending on factors such as hydration status and activity level.

D. Toddlers typically have strong abdominal muscles by the age of 2. This statement is incorrect. While toddlers may develop some abdominal muscle strength through activities such as walking and climbing, their muscle tone and strength are still developing and may not be as strong as in older children or adults.
