Which statement by the mother indicates successful understanding of care for a child treated for bronchiolitis?

The statement regarding the need to wash hands more often reflects a clear understanding of infection control and hygiene, which is crucial in caring for a child with bronchiolitis. Proper hand hygiene helps prevent the spread of respiratory infections, including viruses that can exacerbate conditions like bronchiolitis. This demonstrates that the mother is aware of the importance of minimizing the risk of transmission, not only to herself but also to others around her child, which is vital, especially in managing respiratory illnesses in young children.

The other statements do not indicate the same level of understanding about caring for a child with bronchiolitis. For example, hoping to avoid a cold from the child does not contribute to effective care and indicates a reactive mindset rather than a proactive one focused on prevention. Listening to the chest is not a practical action for a mother without medical training, and taking the child's temperature daily may not be necessary unless specifically instructed by a healthcare provider. The emphasis on hand hygiene underscores proactive engagement in the child’s care and aligns with recommendations for managing infections in pediatric patients.
