The nurse is providing medications to a patient with asthma. What does the nurse recognize about the use of corticosteroid inhalers for this patient?
1. They should be provided after the bronchodilator.
2. They are used only for acute asthma attacks.
3. They are used often with methylxanthines.
4. They are used to activate muscarinic receptors.
Correct Answer: 1
Corticosteroids are given after the bronchodilator, as the bronchodilator opens the airways. Corticosteroids require weeks to begin to have an effect on breathing and therefore cannot be used for acute attacks. Corticosteroids are usually not combined with methylxanthines but may be combined with adrenergic stimulants. The anticholinergics affect the muscarinic receptors.
