Final answer:
The nurse would likely explain that the child is experiencing regression, a common response to the stress of hospitalization, where they revert to earlier comfort behaviors like thumb-sucking to cope with anxiety. The Correct Answer is Option. D.
Step-by-step explanation:
The nurse might explain a six-year-old child's thumb-sucking and baby-talking behaviors while hospitalized for cellulitis to the parents as follows: "These behaviors are indicative of regression, common in stressful situations like hospitalization. It helps the child cope with anxiety." This explanation recognizes that the child may be reverting to earlier stages of development in response to the stress and uncertainty associated with being in a hospital.
Behaviors such as thumb-sucking and seeking comfort through familiar actions, are often a reflection of a child's need for self-soothing during times of distress. Regression occurs when children temporarily fall back to earlier developmental stages, which is a normal part of how they manage their feelings of anxiety or unfamiliarity in certain situations.
It's essential for parents to understand that these behaviors are a normal response to stress and not necessarily indicative of developmental delays or attention-seeking. Offering comfort, understanding, and reassurance to the child during hospitalization can be beneficial.
