Why does the nurse emphasize proper inhaler technique with a 10-year-old boy?

Emphasizing proper inhaler technique with a 10-year-old boy enhances his self-esteem through the mastery of a new skill. At this developmental stage, children are eager to learn and achieve independence in managing their health. Successfully using an inhaler can empower the child, giving him a sense of control over his asthma or respiratory condition. Acquiring this skill not only promotes effective treatment but also reinforces his confidence in handling his medical needs. This mastery contributes positively to his overall self-concept, as he perceives himself as an active participant in his health management.

While the other options touch on important aspects of a child's development and self-concept, they do not specifically relate to the immediate benefits of learning inhaler technique. The focus on skill mastery directly aligns with the child's need for competency and accomplishment, which is a core aspect of developing a positive self-image.
