The nurse is performing a health history on a 6-year-old boy who is having trouble adjusting to school. Which question would be most likely to elicit valuable information?

To calculate the total fluid intake, add up the volume of each item consumed:
- 1⁄2 cup of juice = approximately 120 mL
- 3 oz gelatin = approximately 90 mL
- 1 oz of an ice pop = approximately 30 mL
- 20 mL ginger ale
Total fluid intake = 120 mL (juice) + 90 mL (gelatin) + 30 mL (ice pop) + 20 mL (ginger ale)
= 260 mL

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.
