Correct Answer is B

C. Inhaling slowly and deeply is recommended for effective medication delivery when using an MDI with a spacer.
D. Covering the exhalation slots would prevent proper airflow and could cause the child to inhale exhaled air, which is not recommended during inhalation.
Correct Answer is A
Explanation
A. A child whose parents consistently answer questions on their behalf may indicate a lack of autonomy and could be a sign of potential abuse or neglect, as it may suggest the parents are controlling or overly involved.
