Q

albuterol: RN intervention

A

Prevention is key
Get the flu shot!
Asthma attack - short acting bronchodilators
Inhale short acting inhaler first and then long-acting steroid inhaler (glucocorticoid)
Common cause of asthma attack is not taking medications correctly
Keep rescue inhaler with you at all times
Drink 2 to 3 quarts of fluids to help thin secretions
Use MDI and spacer correctly
Avoid caffeine
Report chest pain and heart palpitations
