Final answer:
Provide immediate care to the boy by assisting him with his asthma inhaler and ensure he sits upright. If symptoms persist, call emergency services as it may be a severe asthma attack requiring medical attention.
Step-by-step explanation:
If a 12-year-old boy who has asthma is experiencing an asthma attack, indicated by wheezing and chest tightness, the first step is to help him use his fast-acting asthma inhaler if he has one. This step is crucial as the inhaler contains medication that can quickly relax and open the airways, providing rapid relief from the symptoms. If he doesn't have an inhaler available, or if the symptoms do not improve within a few minutes after using the inhaler, call emergency services immediately, as this could indicate a severe asthma attack.
In the meantime, while waiting for the medication to take effect or emergency services to arrive, have the boy sit in an upright position which can aid in breathing. Avoid exposure to any potential asthma triggers and keep him calm, as panic can worsen symptoms. Do not offer any food or drink, as this can pose a choking risk.
It's important to monitor the boy's condition closely. If he shows signs of a severe asthma attack, like blue lips or face, confusion, drowsiness, rapid pulse, sweating, or severe anxiety, these are indicators that he needs immediate medical attention. In such cases, do not delay seeking professional help.
