Passage / Scenario
A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthmaA nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
Correct answer
B
Rationale
The spacer increases the amount of medication reaching the lungs by reducing deposition in the mouth and throat, enhancing the therapeutic effect of the MDI. Inhaling rapidly can reduce effectiveness, covering exhalation slots interferes with technique, and while minimizing oropharyngeal deposition is true, the primary benefit is improved lung delivery.
