A nurse collects data from a child descending stairs by placing both feet on each step and holding on to the railing. The nurse should understand that these actions are developmentally appropriate at which of the following ages?
6 years
3 years
4 years
5 years
The Correct Answer is B
A. 6 years: By age 6, most children can walk down stairs alternating feet without needing to hold a railing. Using both feet on each step at this age may indicate a developmental delay in gross motor skills.
B. 3 years: At 3 years old, it is typical for a child to descend stairs using both feet on each step while holding the railing for balance. This reflects age-appropriate coordination and muscle strength.
C. 4 years: Most 4-year-olds begin to alternate feet when descending stairs, showing improvement in balance and leg strength. Using both feet on each step would be more typical for a younger child.
D. 5 years: By age 5, children typically master alternating feet going up and down stairs without assistance. Using both feet on each step would not align with expected motor development at this stage.

Correct Answer is D
Explanation
A. "Newborns do not expand their lungs fully with each respiration." While newborns have smaller lung capacity and immature respiratory mechanics, this does not directly explain why the respiratory rate must be counted for a full minute.
B. "Newborns are abdominal breathers." Abdominal breathing is common in newborns due to diaphragmatic dominance, but this characteristic does not necessitate counting respiratory rate for a full minute. It affects observation location more than timing.
C. "Activity will increase the respiratory rate." Activity level can cause fluctuations in respiratory rate, but the need to count for a full minute is primarily related to irregular rhythm, not just activity changes. Activity effects are an additional consideration but not the main reason.
D. "The rate and rhythm of breath are irregular in newborns." Newborns commonly have irregular breathing patterns, including variable rate and pauses (periodic breathing), which requires a full minute count to accurately assess their true respiratory rate and avoid misinterpretation.
Correct Answer is ["A","C","D","E"]
Explanation
A. Drinks from a cup: By age 2, toddlers typically develop the fine motor skills necessary to drink from an open cup with minimal assistance. This reflects growing independence and coordination.
B. Engages in associative play with other children: Associative play generally emerges around 3–4 years of age. Two-year-olds are more likely to engage in parallel play, where they play beside rather than with peers.
C. Walks independently: Most toddlers begin walking independently between 12 and 18 months. By age 2, this ability is well established and includes improvements in balance and coordination.
D. Speaks up to 20 words: By 24 months, toddlers typically have a vocabulary of about 50 or more words, with some variation. Speaking at least 20 words is an expected developmental milestone at this age.
E. Feeds themselves with a spoon: Using a spoon is a common self-help skill developed around 18–24 months, supporting a toddler’s drive for autonomy and self-feeding abilities.
