Cаse Study “B”:  Rex, а ten-yeаr-оld bоy, suffers frоm asthma.  He is in the dental office to have two teeth extracted for orthodontic purposes.  The doctor is running behind, and Rex has to wait for twenty minutes before he is taken to the operatory.  Once there, Rex begins to cough, wheeze, and struggle for air.  The dentist, aware of Rex’s condition, sends the dental assistant to the waiting room to get the bronchodilator from Rex’s mother.  During this time the dentist stops the treatment and talks calmly to Rex.  Once the bronchodilator is administered, he recovers completely.  What could have been done to assist in the management and/or prevention of this asthmatic episode?
