Henrietta is three years old and has been asked to come to see you today in your clinic for review after an attendance at the local Accident and Emergency Department late last night. She is new to this area.

Henrietta's mother tells you she took her to hospital at about 1a.m. after she woke with cough and difficult breathing. There was an obvious wheeze. She gives you the letter from the Accident and Emergency Dept.
