What device is used to deliver inhaled meds to a child who cannot coordinate inhalation with a spacer?

• A. Metered-dose inhaler
• B. Nebulizer
• C. Dry powder inhaler
• D. Inhalation chamber with spacer

Answer: (B)

When a child can’t coordinate inhalation with a spacer, you need a method that doesn’t depend on breath timing. A nebulizer fits this need because it turns liquid medicine into a fine mist that the child inhales over several minutes, typically through a mask or mouthpiece, while breathing normally. There’s no need to time inhalation with actuation, so even uncooperative or very young children receive the full dose.

In contrast, a metered-dose inhaler (even with a spacer) still requires some coordination between actuation and inhalation; a dry powder inhaler requires a quick, forceful breath; and while a spacer helps, it doesn’t eliminate the need for some breath timing. Therefore, the nebulizer is the best choice for someone who cannot coordinate inhalation with a spacer.
