Which of the Following Suggestions Might You Make to Children

Which of the following suggestions might you make to children with asthma and their parents about exercise?

A) Aerobic conditioning may increase ventilation requirement for activity, thus increasing the rate of ventilation with exertion.
B) Wear a face mask and inhale through the nose to warm up and humidify inhaled air.
C) Use inhalers before going to school because children may not be able to carry inhalers with them during school.
D) Use warm-up and cool-down periods even though it might exacerbate symptoms.
