The nurse is performing a physical assessment of a 10-year-old boy. The nurse notes that during last year's check-up, the child weighed 80 lb. According to average growth for this age group, what would be his expected current weight?

A. Administer at mealtimes: While iron supplements can be given with meals to reduce gastrointestinal upset, they are typically better absorbed on an empty stomach. Therefore, giving them at mealtimes may not optimize absorption.

B. Administer at bedtimE. Administering iron supplements at bedtime is not typically recommended unless specifically instructed by a healthcare provider.

C. Give with a 240 mL (8 oz) glass of milk: Milk can decrease the absorption of iron due to its calcium content, so giving iron supplements with milk is not recommended.

D. Give with orange juicE. Vitamin C enhances iron absorption, so giving iron supplements with orange juice is a common practice to improve absorption.

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.
