What is the preferred delivery method for cromolyn sodium in young children?

1. Large-volume nebulizer

2. Small-volume nebulizer

3. MDI with mask

4. Powder inhaler

The correct answer is: Small-volume nebulizer

The preferred delivery method for cromolyn sodium in young children is through a small-volume nebulizer. This method is particularly effective because it allows for the administration of medication in a gentle aerosol form, which is easier for young children to inhale. Small-volume nebulizers are designed to deliver a concentrated dose of medication directly into the lungs, and their slower delivery provides a higher chance that a child will successfully inhale the medication. Younger patients often have difficulty coordinating their breathing with device use, which makes small-volume nebulizers a favorable option as they do not require the same level of patient cooperation and skill that other methods, such as metered-dose inhalers (MDIs) with masks or powder inhalers, do. These devices can be particularly challenging for young children who may not yet understand how to take deep breaths or use inhalers properly. Therefore, using a small-volume nebulizer effectively addresses the needs of young children by ensuring they receive the necessary medication for optimal respiratory management.
